Description

Technical Field

[0001] This application relates to the field of dental computer-aided design, and in particular to methods, devices, computer equipment and storage media for denture fabrication. Background Technology

[0002] When performing oral treatments, it is necessary to rearrange teeth, especially for patients with missing teeth, such as those with complete or partial edentulism. Currently, the main methods are manual and automated tooth rearrangement. Manual tooth rearrangement relies heavily on the technician's experience and is a complex process. The fabrication of artificial denture bases is cumbersome, typically involving multiple impression taking, pouring, and resin curing steps. This process is complex, has a high failure rate, and repeated modifications not only affect the production cycle but also reduce the precision and consistency of the final restoration. Automated tooth rearrangement and denture base shapes often fail to meet clinical or aesthetic requirements on the first attempt, requiring multiple adjustments and verifications to achieve the desired result. This adjustment process usually relies on the technician's experience, is cumbersome, inefficient, and lacks consistent results. Existing technologies suffer from low tooth rearrangement efficiency. Summary of the Invention

[0057] When treating a patient's original teeth, it is necessary to rearrange the teeth. Currently, the main methods are manual and automated tooth rearrangement. Manual tooth rearrangement relies heavily on the technician's experience and is a complex process. Automated tooth rearrangement often fails to meet clinical or aesthetic requirements on the first attempt, requiring multiple adjustments and verifications to achieve the desired result. This adjustment process typically depends on the technician's experience, is cumbersome, inefficient, and lacks consistent results. Existing technologies suffer from low tooth rearrangement efficiency.

[0058] To address the aforementioned issues, embodiments of this application provide a method, apparatus, computer device, and storage medium for denture generation.

[0059] In some embodiments, the present denture generation method is applied to a denture generation computer device, which may be a terminal or a server. The terminal may be a smartphone, tablet computer, handheld computer, or laptop computer, etc.

[0060] Figure 1 This is a schematic flowchart of the denture generation method provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps S110-S150.

[0061] S110. Obtain the target dental model;

[0062] As an example, in the field of dental computer-aided design, dentists use scanners to scan the patient's mouth to obtain a target dental model, or use scanners to scan physical impressions of the patient's mouth, such as desktop scanners scanning plaster models.

[0063] For patients requiring dentures, the scanned dental model is the patient's actual dental model. The patient may have missing teeth or be about to lose teeth. Therefore, a denture to replace the naturally missing teeth needs to be designed.

[0064] The target dentition model includes dental arch data, based on which the arch morphology can be determined. The dental arches include the maxillary and mandibular arches. The target dentition may include either the maxilla or mandible, with either maxillary or mandibular edentulism; alternatively, the target dentition may include both the maxilla and mandible, with both missing teeth. In other words, the target dentition can be a partial or complete edentulous jaw. Missing teeth may be a few or all teeth.

[0065] S120. Based on the target dental model, determine the first dental arch morphology corresponding to the target dental model and the first row of teeth data corresponding to the first dental arch morphology.

[0066] In this embodiment, the first dental arch is the initial dental arch corresponding to the target dentition. It is generally the patient's dental arch before treatment. If the patient or doctor is dissatisfied with this first dental arch, for example, due to dissatisfaction with the arch shape or occlusion, adjustments to the first dental arch are necessary. The morphology of the first dental arch is derived from data from the target dentition model.

[0067] Correspondingly, the second dental arch is not obtained directly from the target dental model, but rather is derived from improvements made to the first dental arch. For example, the second dental arch is obtained by functionally or aesthetically improving the first dental arch corresponding to the patient's target dental arch.

[0068] Because the tooth arrangement generated by existing automated tooth alignment technology often fails to meet clinical or aesthetic requirements in one go, multiple adjustments and verifications are required to achieve the desired results. The process of adjusting the dental arch involves designing and adjusting the initial arch, or readjusting an already adjusted arch. These adjustments typically rely on the technician's experience, are cumbersome, inefficient, and lack consistent results.

[0069] However, in this application, only a few parameters need to be changed to quickly adjust the tooth alignment and denture shape. After the teeth are aligned, if the current tooth alignment is unsatisfactory, only a few parameters need to be changed to quickly adjust the first dental arch to the second dental arch. The entire process is automated and does not rely on a technician, avoiding the problems of cumbersome operation and low efficiency, and the results are more stable.

[0070] Based on the target jaw model, tooth arrangement design can be performed. Based on the target jaw model, the first dental arch morphology corresponding to the target jaw and the first row of teeth data corresponding to the first dental arch morphology are determined. The first row of teeth data includes the original tooth data obtained when acquiring the jaw, and also includes tooth data generated based on the acquired jaw.

[0071] As an example, the first row of teeth data can be generated from template teeth in the template tooth database. Alternatively, the teeth arrangement can be automatically generated according to user needs, or the initial teeth arrangement can be manually performed by the user, such as a doctor, to obtain the first row of teeth data. There are no restrictions on the method of obtaining the initial teeth arrangement data; it can be generated manually, semi-automatically, or automatically.

[0072] S130. In response to the adjustment command for the first dental arch shape, the first dental arch shape is adjusted to the second dental arch shape.

[0073] This embodiment enables rapid control of the dental arch morphology and automatic adjustment of tooth arrangement, significantly improving tooth arrangement efficiency and consistency.

[0074] As an example, a user manually drags the first dental arch shape to make it more rounded, or adjusts its height or width. Adjustment instructions for the first dental arch shape are generated based on the user's manual dragging action. Alternatively, the user can input adjustment parameters without manual dragging, and adjustment instructions for the first dental arch shape are generated based on these parameters. The dental arch shape can be adjusted via parameters, such as adjusting the width of the front, middle, and back segments of the arch curve, the curvature of the anterior teeth, and symmetry.

[0075] In response to the adjustment instruction for the first dental arch morphology, the first dental arch morphology is adjusted to the second dental arch morphology. The first dental arch morphology is derived from data from the target dental model, typically the patient's dental arch before treatment. The second dental arch morphology is not directly obtained from the target dental model but is obtained by improving upon the first dental arch. The second dental arch morphology is obtained after the first dental arch morphology is changed. After the dental arch morphology is changed, the teeth need to be rearranged according to the new dental arch morphology.

[0076] S130, including S1301-S1302:

[0077] S1301. In response to an adjustment command for the first dental arch shape, extract adjustment parameters from the adjustment command, wherein the adjustment parameters include any one of dental arch curve, dental arch width, dental arch height, and myostatic line of dental arch.

[0078] The dental arch morphology is related to many parameters. In this embodiment, the dental arch curve, dental arch width, dental arch height, and myostatic line of the dental arch are selected. These parameters control the dental arch model.

[0079] Upon receiving an adjustment command for the first dental arch shape, adjustment parameters are extracted from the adjustment command. The adjustment parameters include any one of the following: dental arch curve, dental arch width, dental arch height, and myostatic line of the dental arch.

[0080] S1302. Based on the adjustment parameters, the first dental arch shape is adjusted to the second dental arch shape.

[0081] As an example, based on the width of the dental arch, only the width of the dental arch in the first dental arch shape is adjusted to obtain the second dental arch shape.

[0082] In some embodiments, only one of the dental arch curve, dental arch width, dental arch height, and myostatic line of the dental arch may be adjusted, or multiple of them may be adjusted simultaneously.

[0083] S140. Map the first row of teeth data onto the second dental arch shape to obtain the second row of teeth data temporarily corresponding to the second dental arch shape.

[0084] Because the dental arch shape has changed from the first dental arch shape to the second dental arch shape, the tooth arrangement data corresponding to the original first dental arch shape no longer matches in the second dental arch shape, and it is necessary to rearrange the teeth for the second dental arch shape.

[0085] The first row of teeth data corresponding to the original first dental arch shape is remapped onto the second dental arch shape to obtain temporary second row of teeth data corresponding to the second dental arch shape. This second row of teeth data is temporary and cannot be perfectly matched. That is, this second row of teeth data is the initial tooth arrangement data corresponding to the second dental arch before the adjustment process to optimize the occlusal collision relationship. This temporary second row of teeth data can be displayed in the interactive interface, or it can be used as data during the adjustment process without being displayed separately in the interactive interface.

[0086] S150. Based on the second dental arch morphology, the second tooth arrangement data is adjusted to obtain the target tooth arrangement data.

[0087] In some embodiments, the collision relationship and / or occlusal relationship of the second row of teeth are adjusted by adjusting the position of the teeth, and a new collision relationship and / or a new occlusal relationship is determined based on multiple teeth with new positions.

[0088] Collision relationships include those between adjacent teeth on the same side of the jaw. This includes lateral collision relationships between teeth within the same dental arch, such as those between teeth within the maxillary dental arch.

[0089] Occlusal relationship refers to the mutual occlusal matching relationship between teeth in heterognathic dental arches, that is, the relative pose of the upper and lower jaws in three-dimensional space, which corresponds to the position transformation matrix between the upper and lower jaw models.

[0090] As an example, if the patient's missing tooth is located in the maxillary dental arch, the lateral collision relationship of the teeth within the maxillary dental arch is adjusted, with a focus on adjusting the lateral collision relationship at the site of the missing tooth. In addition to adjusting the lateral collision relationship of the teeth within the maxillary dental arch, selectively, the occlusal relationship at the point of occlusion opposite the missing tooth in the maxillary dental arch can also be adjusted.

[0091] The target dental model also includes heterognathic tooth data corresponding to the first dental arch model, S150, including S1501-S1502:

[0092] S1501. Based on the second row of tooth data, determine the collision relationship between adjacent teeth on the same side.

[0093] In this embodiment, all teeth in the maxilla are referred to as ipsilateral dentition, or all teeth in the mandible are also referred to as ipsilateral dentition. The upper and lower teeth of ectopic dentition refer to the teeth in the maxilla and the teeth in the mandible.

[0094] The collision relationship between adjacent teeth on the same side or the occlusal relationship between upper and lower teeth on the opposite side before tooth arrangement can be determined based on the doctor's experience.

[0095] In some embodiments, the collision and occlusal relationships after tooth arrangement can be determined using tools such as old dentures, wax embankments, cone-beam computed tomography (CBCT), scanners, and dental articulators.

[0096] S1502. Based on the second dental arch morphology, the collision relationship between adjacent teeth on the same side of the second row of teeth is adjusted, wherein the collision distance between adjacent teeth on the same side of the teeth is adjusted.

[0097] As an example, adjusting the lateral collision relationship involves determining the collision distance between teeth within the same maxillary dental arch and / or between teeth within the same mandibular dental arch. This adjustment can be achieved by modifying the collision distance between adjacent teeth using the intercutting value. As another example, the collision distances of adjacent teeth can be constrained to be the same or different; the specific collision distance can be set as needed.

[0098] Selective adjustments may include adjustments to the collision relationship and / or occlusion relationship. Both adjustments can be made by repositioning the teeth. Users may adjust only the collision relationship, only the occlusion relationship, or both.

[0099] The target dental model includes a maxillary model and a mandibular model. Step S150, which involves adjusting the second tooth arrangement data based on the second dental arch morphology to obtain the target tooth arrangement data, further includes steps S1503-S1504:

[0100] S1503. Based on the second upper row of teeth data corresponding to the maxillary model and the second lower row of teeth data corresponding to the mandibular model, determine the occlusal relationship between the maxilla and mandible;

[0101] S1504. Adjust the occlusal relationship of the second upper row of teeth data and the second lower row of teeth data to obtain the target row of teeth data, wherein the collision depth between the upper and lower teeth on the opposite side is adjusted to within a preset depth range.

[0102] As an example, the oral cavity is divided into anterior and posterior regions based on tooth number 3. Tooth number 3 is in a special position, serving as the boundary between the anterior and posterior regions.

[0103] The reason for dividing the tooth base into anterior and posterior regions is that the design is based on the distinct characteristics of each region. These two regions differ significantly in anatomical structure, functional requirements, and aesthetics, thus influencing the formation of the tooth base in different ways.

[0104] The core objective of the anterior region is aesthetic function. When designing the denture base, attention must be paid to the thin, blade-like margins of the anterior region and appropriate buffering of the personalized gingival morphology. The main parameters to consider are aesthetic parameters and anatomical constraint parameters. As an example, a denture base with a certain thickness and convexity is set to restore the normal fullness of the face and lips. Incisive papilla parameters affect the precise buffering or morphological fit of the denture base tissue surface. To assist pronunciation and increase realism, the palatal fold morphology is replicated more accurately. As an example, the axial direction and inclination of the anterior teeth, i.e., the inclination angle of the central anterior teeth during tooth arrangement, directly affect the amount and shape of the cervical region of the central anterior teeth that require denture base support. As an example, the gingival margin morphology and cervical line directly affect aesthetics; the gingival portion of the denture base needs to simulate the wavy contour and gingival papilla morphology of natural gums. Its high point position, curvature, and transition with artificial teeth must be natural; digital design requires precise extraction of this curve from the tooth arrangement results.

[0105] The core objectives for the posterior region are function and support. When designing the denture base, it is important to maximize arch coverage, ensure marginal closure, and incorporate internal reinforcement. The main parameters to consider are mechanical and functional constraints. The dominant parameters for the posterior region include the width and shape of the alveolar ridge crest. A wide, flat alveolar ridge crest is an ideal load-bearing area, and the denture base should fit it tightly with the maximum possible surface area. For sharp or narrow alveolar ridge crests, the denture base design needs to consider better stress distribution, sometimes requiring an intentionally larger base area.

[0106] As an example, the anterior region includes the central incisors, lateral incisors, and canines. The posterior region includes the premolars and molars. Because the teeth corresponding to the anterior region are quite different from those corresponding to the posterior region, the parameters considered when designing a denture base for the anterior region are different from those considered when designing a denture base for the posterior region.

[0107] Adjust the collision depth between heterognathic teeth to within a preset depth range.

[0108] The occlusal relationship between the maxilla and mandible includes mesial relationship, centric relationship, or distal relationship, such as... Figure 2 S1504 adjusts the occlusal relationship of the second upper row of teeth data and the second lower row of teeth data to obtain the target tooth arrangement data, including A1-A3:

[0109] A1. The two contact points between tooth 3 in the second upper row of teeth and teeth 3 to 4 in the second lower row of teeth are symmetrically distributed on the same dental arch. The occlusal relationship is determined based on the contact position of the contact points. The occlusal relationship includes mesial relationship and distal relationship.

[0110] Occlusal relationships include mesial relationship, distal relationship, and centric relationship.

[0111] One method for determining occlusion is as follows: if the contact point falls on the mesial surface of tooth number 4 in the second lower row of teeth, the occlusion is mesial; if the contact point falls directly above the area between teeth number 3 and 4 in the second lower row of teeth, the occlusion is centric; and if the contact point falls on the distal surface of tooth number 3 in the second lower row of teeth, the occlusion is distal.

[0112] In this context, tooth number 3 is a canine, and tooth number 4 is the first premolar. The contact point between the cusp of the maxillary canine number 3 and the mandibular teeth (specifically, the mandibular teeth refer to the mandibular canine number 3 and the mandibular first premolar number 4) is considered a mesial relationship if the contact point falls on the mesial surface of tooth number 4 in the second lower row of teeth. A mesial relationship means the mandible is positioned anteriorly, so the mandibular teeth bite in a position slightly anterior to the maxillary teeth. When the upper and lower teeth bite, the cusp of the maxillary canine crosses the gap behind the mandibular canine and bites on the mesial surface of the mandibular first premolar number 4. The mesial surface of tooth number 4 refers to the anterior surface of tooth number 4, even biting into the gap between tooth number 4 and tooth number 5. This indicates a mesial relationship between the maxilla and mandible. If the contact point falls on the distal surface of tooth number 3 in the second lower row of teeth, the occlusion is considered a distal relationship. Distal relationship means that the mandible is positioned posteriorly, so the mandibular teeth bite in a position that is posterior to the maxillary teeth. This indicates that the mandible is in a distal relationship relative to the maxilla.

[0113] In addition, it should be noted that the method for judging the mesial or distal occlusal relationship is not limited to the above method and can be adjusted according to actual needs.

[0114] A2. For the mesial relationship, the occlusal relationship of the second upper row of teeth data and the second lower row of teeth data is adjusted to obtain the target row of teeth data. The adjustment process includes reducing the collision depth of the molars when adjusting the position of the teeth.

[0115] A3. For the aforementioned distal relationship, the occlusal relationship of the second upper row of teeth data and the second lower row of teeth data is adjusted to obtain the target row of teeth data. The adjustment process includes increasing the collision depth of the molars when adjusting the tooth position.

[0116] The collision depth of tooth #3 is limited, with the point of impact falling between two preset collision points, thus obtaining the required collision depth between maxillary and mandibular tooth #3. Based on the morphologically adjusted new dental arch and the required collision depth, the collision depth of the heterognathic teeth is determined.

[0117] Based on the dental data of tooth #3 (the non-occlusal tooth), the collision depth between tooth #3 and tooth #3 (the non-occlusal tooth) in the second row of dental data can be determined. The collision depth of tooth #3 in the second row of dental data is then adjusted to within a preset depth range.

[0118] As an example, the contact point between tooth number 3 in the second upper row of teeth and teeth 3-4 in the second lower row of teeth is determined. The occlusal relationship is then determined based on the contact point: mesial, centric, or distal. If the contact point falls directly above the area between teeth 3-4 in the second lower row of teeth, the occlusal relationship is centric. A centric relationship requires no adjustment, while mesial and distal relationships require adjustment. The impact depth of the molars is then adjusted sequentially based on either the mesial or distal relationship.

[0119] In a standard occlusion, the maxillary third tooth and the mandibular fourth tooth should be in a centric relationship, meaning the cusp of the maxillary third tooth should fall precisely into the contact space between the mandibular third tooth and the mandibular fourth premolar. If the cusp of the maxillary third tooth does not fall into the contact space, it is not a centric relationship. This indicates a misalignment of the maxillary and mandibular dental arches, such as an overall occlusion commonly referred to as an overbite or protruding teeth. The mandible is in a receding position relative to the maxilla.

[0120] Because mesial or distal relationships influence the pattern of lateral chewing movements. During lateral movements, the maxillary canine on the working side slides along the mandibular canine, guiding the teeth in the posterior region out of contact. The denture base must adapt to and support this dynamic movement process to ensure the stable function of the prosthesis. Therefore, when designing the denture base, the impact depth of the molars is adaptively adjusted according to the mesial or distal relationship of the third tooth.

[0121] Specifically, in cases of distal relationship, the impact depth of the molars is reduced; in cases of mesial relationship, the impact depth of the molars is increased. Based on the contact point between the cusp of the maxillary canine (tooth 3) and the mandibular teeth 3-4, the occlusal relationship can be effectively constrained.

[0122] In S1504, the occlusal relationship of the second upper row of teeth data and the second lower row of teeth data is adjusted to obtain the target tooth arrangement data. Then, the overbite and overjet relationship between the second upper row of teeth data and the second lower row of teeth data is adjusted to obtain the target tooth arrangement data.

[0123] The pre-defined overbite-overjet relationship refers to the overbite-overjet relationship between the maxillary and mandibular dental arches.

[0124] Constraints are applied to the data of the second upper row of teeth and the data of the second lower row of teeth to constrain the overbite and overlay relationships between heterognathic arches, thereby obtaining the target tooth arrangement data.

[0125] At this point, based on the original tooth arrangement data in the dental arch, it is mapped onto the new dental arch. The tooth arrangement data is transferred seamlessly to the new dental arch, resulting in a stable and adaptive alignment on the new arch shape. Without relying on the technician's experience, the position of the entire row of teeth is controlled with a few parameters, achieving rapid and accurate adjustment of tooth arrangement.

[0126] In some embodiments, after obtaining the target tooth arrangement data based on the new dental arch, the target tooth arrangement data can be processed and applied in many scenarios.

[0127] As an example, the target tooth arrangement data obtained after arranging teeth based on the new dental arch is used to generate a denture base model when making the denture base.

[0128] When patients lose their natural teeth due to cavities, periodontal disease, trauma, or congenital absence, they can restore basic functions such as chewing, speech, and facial appearance by wearing or installing dentures. Dentures, also known as "false teeth," are artificial restorations used to replace missing natural teeth and adjacent structures. During dental treatment of a patient's natural teeth, dentures replace them and are fixed to the patient's gums via a denture base. There are many types of dentures, such as removable dentures, fixed dentures, and implant dentures. Removable dentures are those that patients can put on and take off themselves. They generally consist of a denture base and artificial teeth; the base is fitted onto the patient's remaining natural teeth for a stable position. The fabrication process for removable dentures is relatively simple. Fixed dentures, on the other hand, cannot be removed by the patient. They are fixed between the natural teeth using the patient's remaining natural teeth as support. Fixed dentures are characterized by their closer resemblance to natural teeth; when fitting a fixed denture, it is necessary to grind down the adjacent natural teeth beforehand. Finally, dental implants are currently the most advanced method of tooth restoration. This involves inserting an artificial tooth root, or implant, into the alveolar bone in the area of ​​the missing tooth. Once the implant has firmly integrated with the patient's alveolar bone, a crown is attached to it. Dentures can also be categorized according to the extent of restoration. For example, partial dentures are used to fill the missing tooth if only a single tooth or a few teeth are to be restored, while complete dentures are used to fill the entire missing jaw if the entire upper or lower jaw is to be restored. In this embodiment, the dentures referred to are removable dentures, including removable partial dentures and removable complete dentures.

[0129] In denture treatment, the dentist first aligns the artificial teeth (prosthetic teeth) and then fabricates the denture base based on this alignment. This alignment involves precisely placing each artificial tooth onto the base according to its correct anatomical position and occlusal relationship. The base is a crucial component of removable dentures; it is the pink artificial gum tissue that supports the bite force and transmits it to the underlying alveolar bone. Currently, the primary methods are artificial tooth alignment and custom-designed bases. Artificial tooth alignment relies heavily on the technician's experience and is complex. Custom-designed bases require multiple impressions, molding, and resin curing steps, making the process intricate and potentially requiring revisions. Therefore, the production of denture bases is slower when designed.

[0130] After S150, such as Figure 3 Including S160-S190:

[0131] S160. In response to a denture base generation command for the target tooth arrangement data, acquire denture base control data for the target tooth arrangement data;

[0132] The final shape of the denture base is controlled by the control data of the target dental model, which is influenced by many factors. The patient's physiological parameters directly affect the final shape of the denture base. First, the three-dimensional morphology of the patient's alveolar ridge has the most direct impact on the shape of the denture base. Its length, width, and height determine the overall size and support area of ​​the denture base. Its slope affects the marginal closure design of the denture base. Second, the occlusal relationship, such as the relative position of the upper and lower jaws, affects the overall spatial layout and lingual morphology of the denture base. Finally, the influence of these physiological parameters on the denture base still needs to be limited by specific numerical rules. For example, the thickness range of the denture base should consider the influence of the denture base material and patient comfort; the edge shape of the denture base should be thin-edged, rounded, or have a certain thickness; the edge area of ​​the denture base should smoothly transition to a thin-edged shape; and there are also parameters such as the extension range of the denture base.

[0133] In response to a denture base generation command based on target tooth arrangement data, acquire denture base control data based on the target tooth arrangement.

[0134] In some embodiments, the denture base control data includes at least one of the following: dental arch morphology, gingival boundary control parameters, and thickness control parameters.

[0135] S170. Based on the base control data, generate a temporary bottom base model;

[0136] The baseplate control data includes gingival boundary control parameters and thickness control parameters. Based on the gingival boundary control parameters and thickness control parameters, a temporary baseplate model is generated.

[0137] The bottom temporary denture model represents the denture base portion that adheres to the alveolar ridge mucosa. It is typically a triangular mesh or parametric surface that defines the outer edge of the denture base.

[0138] As an example, a temporary base model is generated based on the myostatic line.

[0139] S180. Based on the temporary base model and the target tooth arrangement data, generate a gingival model;

[0140] The gingival margin is a continuous closed spatial curve at the neck of each tooth, defining the boundary between the tooth and the gingiva.

[0141] A gingival model is generated based on the gingival margin line corresponding to the bottom temporary base model and the target tooth arrangement data.

[0142] A gingival model includes the anatomical structure of the gingiva, which includes keratinized gingiva and gingival papillae.

[0143] S190. The temporary base model at the bottom is smoothly fused with the gingival model to obtain the denture base model.

[0144] The transition surfaces and gingival papilla surfaces of the gingival model are Boolean-unified with the underlying temporary denture model to ensure a seamless connection. The merged surfaces are then smoothed to eliminate sharp edges or unevenness while preserving important anatomical features, resulting in the denture base model. Parametric control of the gingival anatomy allows for personalized generation of gingival structures such as keratinized gingiva or gingival papillae, ensuring the denture base meets both functional and aesthetic requirements for the patient.

[0145] The process of generating denture base models based on control parameters on the updated dental arch is convenient and quick, eliminating the need for manual tooth alignment and base design, and is independent of technician experience. It enables digital and iterative generation of denture bases, improving model generation efficiency. Furthermore, it enhances base consistency, ensuring the generated bases are independent of individual experience.

[0146] As an example, when the generated denture base model does not meet expectations, it can be regenerated by adjusting parameters, thus achieving rapid iterative digital denture base models.

[0147] After S190, such as Figure 4 Including C1-C2:

[0148] C1, If ​​the denture base model does not meet the preset requirements, then new base control data is obtained;

[0149] If the denture base model does not meet the preset requirements, new base control data is obtained.

[0150] C2, based on the new baseboard control data, updates the baseboard control data.

[0151] Based on the new denture base control data, the denture base control data is updated. Specifically, based on the new denture base control data and the bottom temporary denture base model, a new gingival model is regenerated. The bottom temporary denture base model and the new gingival model are then smoothly fused together to obtain a new denture base model.

[0152] In this embodiment, the basement model is validated and updated after generation, making the generated basement model more in line with the expected effect and improving the accuracy of the generated basement model. The revised basement model is used in advance to avoid the loss caused by discovering that it is unsuitable during future use by patients and then having to make modifications.

[0153] After smoothly fusing the temporary denture base model with the gingival model in S190 to obtain the denture base model, including D1-D2:

[0154] D1. Based on the target tooth arrangement data and the denture base model, determine the denture model;

[0155] D2. Send the denture model to a preset user terminal, or send the denture model to a 3D printing device for the 3D printing device to print based on the selected material.

In this application embodiment, based on the mapping of tooth arrangement data in the original dental arch, the tooth arrangement data is seamlessly transferred to the new dental arch, adaptively aligned on the new arch, and achieves rapid adjustment of the tooth arrangement without relying on the technician's experience.
