Abstract
Description
Technical Field
[0001] This invention relates to the field of removable partial dentures, and more specifically to a planar design communication method for removable partial dentures. Background Technology
[0002] Removable partial dentures are manufactured according to a standardized process. The overall procedure involves first obtaining an impression, pouring a standard plaster model, and then designing the entire removable partial denture on this model. The positioning angle of the denture is observed and analyzed using an instrument, or computer-aided design is used to find the positioning angle and the corresponding area to be ground down. However, a problem arises: it's unclear whether the observation and analysis should be performed by the dentist or a technician. Furthermore, the core issue of partial denture design can be highly variable. Each patient has unique characteristics, and each dentist's design perspective differs, resulting in each denture being completely unique. It's rare to encounter identical cases clinically, due to factors such as the design plan, the area to be ground down, loose natural teeth, and decay. Each denture may also require a different clinical approach. Because dentists are often busy, or many are general practitioners, communication regarding the design plan may be unclear, leading to low communication efficiency in removable partial denture work and impacting the patient experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a planar design communication method for removable partial dentures that is clear in expression and highly efficient in communication.
[0004] This invention is achieved through the following technical solution:
[0005] A planar design communication method for removable partial dentures includes the following steps:
[0006] S1: Determine the basic information of outpatients, patients, and doctors to prevent misdesign of plans among multiple outpatients or multiple patients within an outpatient clinic;
[0007] S2: Fill in the problems found through the analysis of the plaster model, and the corresponding solutions, including which tooth is suspected to be loose, whether to consider extraction later, or whether the upper and lower bites are too tight to repair the defect with long rings and artificial resin teeth, etc.
[0008] S3: Determine the denture placement direction, select the major connector, select the clasp, and select the support;
[0009] S4: Description of tooth preparation;
[0010] S5: Specify the exact height, width, and thickness of the prepared teeth, specify the placement angle and direction of the prosthesis, mark the issues that need to be considered during tooth grinding, and show a rough design plan.
[0011] Furthermore, in S2, the upper and lower jaw models are observed and analyzed, and lines are drawn to obtain the denture placement angle and the amount of material removed, allowing problems to be identified from four perspectives.
[0012] Furthermore, in S3, determining the denture placement direction is related to the overall design scheme, and the angle at which all the tooth grinding positions mentioned later are established.
[0013] Furthermore, regarding the selection of the large connector in S3, many doctors are unclear about which large connector is more suitable for the patient, or this is not fully discussed during the patient's first visit. The selection scheme for denture large connectors provided here is convenient for both doctors and patients to understand.
[0014] Furthermore, in S3, the selection of clasps is a prerequisite for determining which tooth might be prepared. The corresponding clasp selection also indirectly tells the doctor whether it will affect the patient's aesthetics, or that the doctor has already marked the aesthetic issues that need to be considered during the design when mailing the model.
[0015] Furthermore, in S3, the choice of abutment tells the dentist which tooth needs to be supported by the denture, or whether it does not need to be supported at all.
[0016] Furthermore, in S4, the textual description of tooth preparation will use professional medical terminology to tell the doctor which tooth needs to be ground down, the location of the grinding, and the height, width, and thickness of the grinding.
[0017] Furthermore, in S5, the doctor can clarify the meaning of the specific height, width, and thickness of the tooth preparation mentioned above.
[0018] Furthermore, in S5, the positioning angle of the denture refers to the positioning angles of both the upper and lower jaws.
[0019] Furthermore, in S5, a rough design scheme is shown from the cheek side in this case. This scheme allows the doctor to clearly understand what the general design of the case should look like, and also shows the images that represent the various components that need to be described in the denture design.
[0020] Compared to existing technologies, this invention addresses problems identified through plaster model analysis and provides corresponding solutions. It determines the denture placement direction, the selection of major connectors, clasps, and supports; describes tooth preparation, specifying the height, width, and thickness of the prepared teeth; clarifies the denture placement angle; marks issues to consider during tooth grinding; and presents a general design scheme. This addresses doctors' design challenges for partial dentures. By analyzing various issues observed in the model, corresponding solutions are identified, and problems are resolved through a design communication form. This significantly saves clinical treatment time, frees up doctors' hands, and allows more young doctors with no prior experience in partial dentures to quickly understand a rational and standardized design and begin fabricating for patients. The clear communication of the design scheme improves medical communication efficiency and enhances the patient experience. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] like Figures 1 to 4 The present invention discloses a planar design communication method for removable partial dentures, comprising the following steps:
[0028] S1: Determine the basic information of outpatients, patients, and doctors to prevent misdesign of plans among multiple outpatients or multiple patients within an outpatient clinic;
[0029] S2: Fill in the problems found through the analysis of the plaster model, and the corresponding solutions, including which tooth is suspected to be loose, whether to consider extraction later, or whether the upper and lower bites are too tight to repair the defect with long rings and artificial resin teeth, etc.
[0030] S3: Determine the denture placement direction, select the major connector, select the clasp, and select the support;
[0031] S4: Description of tooth preparation;
[0032] S5: Specify the exact height, width, and thickness of the prepared teeth, specify the placement angle and direction of the prosthesis, mark the issues that need to be considered during tooth grinding, and show a rough design plan.
[0033] By filling out the analysis of problems found through plaster models and their corresponding solutions, the placement direction of the prosthesis, the selection of major connectors, clasps, and rests are determined. The tooth preparation is described, specifying the height, width, and thickness of the prepared teeth, the placement angle of the prosthesis, and the issues that need attention during tooth grinding. A rough design scheme is presented, which can solve the doctor's design problems for partial prostheses. By analyzing various problems seen on the model, corresponding solutions are sorted out, and problems are solved through design communication forms, greatly saving clinical treatment time, freeing up the doctor's hands, and allowing more young doctors with no experience in partial prostheses to quickly understand a rational and standardized design and begin making them for patients. The clear expression and communication of the design scheme improves the efficiency of medical communication and enhances the patient experience.
[0034] In S2, the upper and lower jaw models are observed and analyzed, and lines are drawn to obtain the denture placement angle and the amount of material removed. Problems are identified from four perspectives. Here, the top view shows the patient's most pressing concern: the morphology of the major connections. This facilitates communication with the dentist, ensuring the design is perfectly suited to the patient's current needs, rather than a rough outline or a plan based on someone else's case. This avoids conflicts between the dentist's later recommendations and the patient's desired outcome.
[0035] In S3, determining the orientation of the denture placement is related to the overall design scheme, as well as the angle at which all tooth grinding positions mentioned later are based.
[0036] In S3, the choice of large connectors is often unclear to dentists, who may not be sure which type is best suited for each patient, or this may not have been fully discussed during the initial patient visit. This guide provides a selection scheme for denture large connectors to help both dentists and patients understand the process.
[0037] In S3, the choice of clasps is a prerequisite for indicating which tooth might be prepared. The corresponding clasp selection also indirectly tells the doctor whether it will affect the patient's aesthetics, or whether the doctor has marked the aesthetic issues to be considered when designing the model when mailing it. Here, we can give the doctor a design suggestion.
[0038] In S3, the choice of abutment tells the dentist which tooth needs to be supported by the denture, or whether it doesn't need support at all.
[0039] In S4, the written description of tooth preparation will use professional medical terminology to tell the doctor which tooth needs to be ground down, the location to be ground down, and the height, width, and thickness of the tooth to be ground down.
[0040] In S5, the dentist can clarify the meaning of the specific height, width, and thickness of the tooth preparation mentioned above.
[0041] In S5, the positioning angle of the denture is shown, which includes the positioning angles of both the upper and lower jaws.
[0042] S5 shows a rough design scheme from the cheek side in this case. This scheme allows the doctor to clearly understand what the general design of the case should look like. It also shows the images that represent the various components that need to be represented when designing the denture.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
