Description

Technical Field

[0001] The present application relates to the technical field of oral restoration, and in particular to a bridge structure and a tooth restoration system for tooth restoration. Background Art

[0002] Pontic Shield (bridge protection technology) belongs to the field of oral restoration and is an alternative technology for maintaining the alveolar ridge after tooth extraction. During tooth extraction, only part of the tooth root is removed, and a part of the vestibular surface of the root (the side close to the lips or cheek), usually a root fragment of about 1 mm thick, is retained. The retained root portion and the surrounding periodontal tissue help maintain the blood supply and physiological function of the alveolar bone, reduce alveolar bone resorption and remodeling after tooth extraction, especially the absorption of the buccal bone plate. The retained root fragment can provide better alveolar bone conditions and gingival morphology support for subsequent denture restorations, such as dental implants or fixed bridge restorations.

[0003] Compared with traditional methods such as not taking special measures after tooth extraction or only using bone graft materials, Pontic Shield technology can significantly reduce the absorption of alveolar bone after tooth extraction, better maintain the height and width of the alveolar ridge, and provide a good bone foundation for later repair. It helps to maintain the natural shape and fullness of the gums, especially in aesthetic areas such as the anterior teeth, which is crucial for achieving beautiful restoration effects. To a certain extent, it avoids complex bone augmentation surgery or soft tissue transplantation surgery, reduces surgical trauma and treatment time for patients, and also reduces treatment costs and the risk of complications.

[0004] The "pontic" in Pontic Shield refers to the bridge that is used to replace missing teeth and connect the abutment teeth at both ends. It can restore the appearance and some functions of teeth. The current bridge is designed with a denture cavity at the position of the missing teeth to maintain beauty and maintain the extraction space. However, the adjacent teeth are prone to fall to the cavity position during the movement process, which leads to abnormal growth of teeth. Summary of the invention

[0005] Based on this, it is necessary to provide a bridge structure and a tooth restoration system for tooth restoration in order to solve the above-mentioned technical problems.

[0014] In one embodiment, the first blocking surface and the second blocking surface are both configured as arcuate surfaces, wherein at least one of the first blocking surface and the second blocking surface is recessed along a direction from the tooth body cavity toward the cavitation cavity to form an arcuate surface.

[0015] In one embodiment, different tooth sockets have different maximum socket depths, and the maximum height of the blocking body is less than or equal to the maximum socket depth of the adjacent tooth socket.

[0033] See also Figures 1 to 3 As shown, the present application provides a bridge structure for tooth restoration, the bridge structure comprising a dental bridge body 1000 and a blocking component 2000. The dental bridge body 1000 and the blocking component 2000 are generally configured as an integrally formed structure. For example, the dental bridge body 1000 and the blocking component 2000 can be integrally formed and made of the same material by 3D printing. In one embodiment, the 3D printing method can be selected as liquid resin printing, also known as liquid resin photocuring 3D printing. Liquid resin printing is an additive manufacturing technology that uses liquid photosensitive resin as material to construct three-dimensional objects layer by layer through the principle of photocuring.

[0034] The basic principle of liquid resin printing is photocuring reaction, that is, when light of a specific wavelength is irradiated to the liquid photosensitive resin, the photoinitiator in the resin absorbs light energy and produces active species such as free radicals or cations. These active species trigger the polymerization reaction of monomers and prepolymers in the resin, so that the liquid resin quickly changes from liquid to solid, and prints a solid model part on the molding table. The model part is the dental bridge body 1000 and the blocking component 2000 of the above-mentioned one-piece molding structure. When the model part is printed, it is in a suspended state upside down on the molding table. At this time, an automatic unloading device is required to separate the top of the model part from the molding table so that the model part can fall freely.

[0035] Based on the above-mentioned 3D printing method, the thickness and position of the blocking component 2000 on the dental bridge body 1000 can be freely adjusted, and then it can be combined with the orthodontic correction plan to provide additional treatment force to help open or close the tooth extraction gap. Specifically, the operator can customize the thickness and position of the blocking component 2000 on the dental bridge body 1000 on the digital model according to the treatment needs, so as to design the best structure suitable for the patient's oral problems. In addition, those skilled in the art can choose appropriate materials and 3D printing production methods according to actual needs, which are not limited here.

[0036] For the convenience of description, the dental bridge body 1000 may be configured to be limited to a linear virtual distribution track 1001. It should be noted that the linear virtual distribution track 1001 is only a non-existent virtual track introduced for the convenience of describing the structural design of the dental bridge body 1000, and is not a track line actually existing on the dental bridge body 1000. Therefore, based on Figure 1 The shape of the linear virtual distribution trajectory 1001 can limit the dental bridge body 1000 to be provided with a plurality of tooth body cavities 1100 and at least one cavitation chamber 1200 along the linear virtual distribution trajectory 1001, wherein the tooth body cavities 1100 are used to be fixed on the teeth, and the cavitation chamber 1200 is used to isolate the gap between two teeth, therefore, each of the cavitation chambers 1200 is located between two adjacent tooth body cavities 1100.

[0037] Therefore, the number of tooth body cavities 1100 and the number of cavitation chambers 1200 set on the dental bridge body 1000 need to be designed specifically according to the actual conditions of the teeth of different patients. At the same time, the shape, size, etc. of each tooth body cavity 1100 and each cavitation chamber 1200 also need to be designed specifically. Technical personnel in this field can make the dental bridge body 1000 according to the actual conditions of the patients, and there is no limitation here.

[0038] In the present application, in order to solve the problem that adjacent teeth are prone to fall toward the position of the cavitation chamber 1200 during movement, thereby causing abnormal growth of teeth, a blocking component 2000 is provided on the dental bridge body 1000. The number of blocking components 2000 can be determined according to the number of cavitation chambers 1200. Therefore, the number of the blocking components 2000 can be configured to be at least one, so that at least one or several of the cavitation chambers 1200 can be equipped with the blocking component 2000 according to actual needs. The blocking component 2000 is matched with the cavitation chamber 1200, so that the blocking component 2000 is configured to isolate the cavitation chamber 1200 and at least one adjacent tooth body cavity 1100.

[0039] Therefore, the blocking component 2000 can provide support between the cavitation chamber 1200 and the adjacent tooth body cavity 1100, support the adjacent teeth, and prevent the teeth from falling over during the movement, thereby effectively preventing the teeth from growing abnormally and affecting the treatment expectations. Among them, the thickness and position of the dental bridge body 1000 can be adjusted according to actual conditions, and additional therapeutic force can be provided based on the adjustment of the position and thickness of the dental bridge body 1000 to help expand or reduce the gap between missing teeth. For example, in combination with an orthodontic treatment plan, additional therapeutic force can be provided to help open or close the extraction gap.

[0040] In one embodiment, the blocking component 2000 can be configured to isolate the cavitation chamber 1200 and at least one adjacent tooth housing cavity 1100, or the blocking component 2000 can be configured to simultaneously isolate the cavitation chamber 1200 and two adjacent tooth housing cavities 1100. That is, those skilled in the art can decide to provide support between the cavitation chamber 1200 and a certain adjacent tooth housing cavity 1100 according to actual conditions to solve the problem of tooth lodging in a targeted manner, which is not limited here.

[0041] The blocking component 2000 can be designed into a variety of structures. For example, in one embodiment, the blocking component 2000 can include at least two blocking bodies 2100, at least one blocking body 2100 is disposed between the cavitation chamber 1200 and an adjacent tooth housing cavity 1100, and at least one blocking body 2100 is disposed between the cavitation chamber 1200 and another adjacent tooth housing cavity 1100. Therefore, the two blocking bodies 2100 can provide support on the left and right sides of the cavitation chamber 1200, respectively, to prevent the teeth on the left and right sides from falling toward the cavitation chamber 1200. In one embodiment, at least one of the blocking bodies 2100 and the dental bridge body 1000 are configured as an integrally formed structure, or all of the blocking bodies 2100 and the dental bridge body 1000 are configured as an integrally formed structure.

[0042] In one embodiment, the blocking body 2100 is configured as a plate-shaped blocking. For example, the plate-shaped blocking has a first blocking surface 2101 and a second blocking surface 2102 facing oppositely, wherein the first blocking surface 2101 and the second blocking surface 2102 are configured to face the adjacent cavitation chamber 1200 and the tooth body cavity 1100 respectively, and at least one of the first blocking surface 2101 and the second blocking surface 2102 is configured as an arc surface, and the shape of the arc surface can be designed according to actual conditions.

[0043] For example, in one embodiment, the first blocking surface 2101 and the second blocking surface 2102 are both configured as arc-shaped surfaces, such as Figure 2 and Figure 3 As shown, at least one of the first blocking surface 2101 and the second blocking surface 2102 is recessed in the direction from the tooth housing cavity 1100 toward the cavitation chamber 1200 to form an arc surface, thereby allowing the teeth in the tooth housing cavity 1100 to contact the recessed direction of the arc surface, forming a more stable force contact state with a larger contact area.

[0044] At this time, the arc surface of the first blocking surface 2101 should fit the surface of the tooth contained in the corresponding tooth housing 1100, so as to provide better support. In addition, if the target patient is undergoing orthodontic plastic surgery, the blocking component 2000 can also configure its structure and position according to the orthodontic correction plan, so as to provide additional correction force to the teeth contained in the tooth housing 1100 in combination with the orthodontic correction plan.

[0045] Therefore, the thickness and position of the blocking component 2000 mentioned above on the dental bridge body 1000 can be freely adjusted, which is equivalent to the thickness and position of each blocking body 2100 on the dental bridge body 1000 being freely adjusted, wherein the thickness of each blocking body 2100 is Figure 3 The thickness formed between the first blocking surface 2101 and the second blocking surface 2102 as shown can arbitrarily adjust the thickness of each blocking body 2100 and arbitrarily adjust the position of each blocking body 2100 based on the advanced manufacturing method of 3D printing, so that the thickness and position of each blocking body 2100 have highly flexible adjustability, and the thickness of the blocking assembly 2000 can also be customized in combination with the orthodontic correction plan.

[0046] In one embodiment, different dental cavities 1100 have different maximum cavity depths. Since the different dental cavities 1100 are configured to accommodate teeth of specific shapes, each dental cavity 1100 has its own specific cavity structure, including a specific shape and depth. At this time, the depth from the cavity opening to the deepest cavity bottom position in the dental cavity 1100 can be defined as the maximum cavity depth of the dental cavity 1100.

[0047] The maximum height of the blocking body 2100 is less than or equal to the maximum cavity depth of the adjacent tooth cavity 1100. Moreover, different cavitation chambers 1200 have different maximum cavity depths, and the maximum height of the blocking body 2100 is less than or equal to the maximum cavity depth of the adjacent cavitation chamber 1200. For example, the maximum height of the blocking body 2100 is less than the maximum cavity depth of the adjacent tooth cavity 1100, and the maximum height of the blocking body 2100 is less than the maximum cavity depth of the adjacent cavitation chamber 1200, so that the blocking body 2100 can reduce its height as much as possible while providing sufficient support to prevent adverse effects on the gums around the teeth.

[0048] The present application provides a tooth restoration system, which includes the bridge structure. Since the specific structure, functional principle and technical effect of the bridge structure are described in detail above, they will not be repeated here. Any technical content related to the bridge structure can refer to the above records.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
