Description

TECHNICAL FIELD

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

[0002] Pontic Shield belongs to the technical field of oral prosthetics, which is a kind of alternative technology for maintaining the alveolar ridge after tooth extraction. During tooth extraction, only part of the tooth root is extracted, and a part of the vestibular surface (the surface close to the lip or cheek) of the tooth root is retained, usually about 1 millimeter thick. The retained part of the tooth root and the surrounding periodontal tissue help maintain the blood supply and physiological function of the alveolar bone, reduce the absorption and remodeling of the alveolar bone after tooth extraction, especially the absorption of the buccal bone plate. The retained tooth root fragment can provide better alveolar bone conditions and gum shape support for subsequent dental restoration, such as implant or fixed bridge restoration.

[0003] Compared with the traditional method of not taking special measures or only using bone grafting materials after tooth extraction, 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 the aesthetic area such as the anterior tooth area, which is crucial for achieving an aesthetically pleasing repair result. To a certain extent, it avoids complex bone augmentation surgery or soft tissue transplantation surgery, reduces the surgical trauma and treatment time of the patient, and also reduces the treatment cost and the risk of complications.

[0033] Referring to Figures 1 to 3 As shown, the present application provides a bridge structure for dental restoration, which comprises a dental bridge body 1000 and a barrier assembly 2000, the dental bridge body 1000 and the barrier assembly 2000 are generally configured as an integral structure, for example, the dental bridge body 1000 and the barrier assembly 2000 can be 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 build three-dimensional objects layer by layer through photocuring principle.

[0034] The basic principle of liquid resin printing is photocuring reaction, that is, when a specific wavelength of light irradiates the liquid photosensitive resin, the photoinitiator in the resin will absorb light energy and produce active species such as free radicals or cations, these active species initiate the polymerization reaction of monomers and prepolymers in the resin, making the liquid resin rapidly change from liquid to solid, and printing a solid model piece on the forming table, which is the dental bridge body 1000 and the barrier assembly 2000 of the above-mentioned integral structure, wherein the model piece is in a suspended state when printing is completed, at this time, the automatic unloading device is needed to separate the top end of the model piece from the forming table, so that the model piece falls freely,

[0035] Based on the above-mentioned 3D printing method, the thickness and position of the barrier assembly 2000 on the dental bridge body 1000 can be freely adjusted, thereby providing additional treatment force in combination with the orthodontic treatment plan to help open or close the extraction space. Specifically, the operator can customize the thickness and position of the barrier assembly 2000 on the dental bridge body 1000 on the digital model according to the treatment needs, thereby designing the best structure suitable for the patient's oral problems. In addition, those skilled in the art can select appropriate materials and 3D printing methods according to actual needs, which are not limited here.

[0036] For the convenience of description, the dental bridge body 1000 can be configured to define a linear virtual distribution track 1001, it should be noted that the linear virtual distribution track 1001 is a virtual track that does not exist and is introduced only 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 the shape of the linear virtual distribution track 1001, the dental bridge body 1000 can be provided with a plurality of dental sleeve cavities 1100 and at least one air bubble chamber 1200 along the linear virtual distribution track 1001, wherein the dental sleeve cavity 1100 is used to fix the sleeve on the tooth, and the air bubble chamber 1200 is used to isolate the gap between two teeth, therefore, each air bubble chamber 1200 is located between two adjacent dental sleeve cavities 1100. Figure 1

[0037] Therefore, the number of dental sleeve cavities 1100 and the number of air bubble chambers 1200 provided on the dental bridge body 1000 need to be designed according to the actual situation of the teeth of different patients, and the shape, size, etc. of each dental sleeve cavity 1100 and each air bubble chamber 1200 also need to be designed, and those skilled in the art can manufacture the dental bridge body 1000 according to the actual situation of the patient, which is not limited herein.

[0038] In the present application, in order to solve the problem that adjacent teeth are prone to grow abnormally when moving to the position of the air bubble chamber 1200, a blocking assembly 2000 is provided on the dental bridge body 1000, the number of blocking assemblies 2000 can be determined according to the number of air bubble chambers 1200, therefore, the number of blocking assemblies 2000 can be configured to be at least one, so that at least one or a plurality of air bubble chambers 1200 can be equipped with the blocking assembly 2000 according to actual needs, the blocking assembly 2000 matches the air bubble chamber 1200, so that the blocking assembly 2000 is configured to isolate the air bubble chamber 1200 and at least one adjacent dental sleeve cavity 1100.

[0039] Therefore, the blocking assembly 2000 can provide anchorage between the air bubble chamber 1200 and the adjacent dental sleeve cavity 1100, support the adjacent teeth, and avoid the occurrence of involution of the teeth during movement, thereby effectively avoiding the abnormal growth of the teeth and avoiding affecting the treatment expectation. Wherein the thickness and position of the dental bridge body 1000 can be adjusted according to the actual situation, and additional treatment force is provided based on the adjustment of the position and thickness of the dental bridge body 1000 to help expand or narrow the edentulous space. For example, additional treatment force is provided in combination with an orthodontic treatment scheme to help open or close the edentulous space.

[0040] ​In one embodiment, the barrier assembly 2000 can be configured to isolate the air bubble chamber 1200 and at least one of the adjacent tooth sleeve cavities 1100, or the barrier assembly 2000 can be configured to isolate the air bubble chamber 1200 and two of the adjacent tooth sleeve cavities 1100 at the same time. That is, the skilled person can decide to provide anchorage between the air bubble chamber 1200 and a certain adjacent tooth sleeve cavity 1100 according to the actual situation to solve the problem of tooth involution, which is not limited herein.

[0041] The barrier assembly 2000 can be designed in various structures. For example, in one embodiment, the barrier assembly 2000 can include at least two barrier bodies 2100, at least one of the barrier bodies 2100 is arranged between the air bubble chamber 1200 and one of the adjacent tooth sleeve cavities 1100, and at least one of the barrier bodies 2100 is arranged between the air bubble chamber 1200 and another of the adjacent tooth sleeve cavities 1100. Thus, the two barrier bodies 2100 can provide anchorage on the left and right sides of the air bubble chamber 1200, respectively, to prevent the teeth on the left and right sides from involution to the air bubble chamber 1200. In one embodiment, at least one of the barrier bodies 2100 is configured in an integral structure with the dental bridge body 1000, or all of the barrier bodies 2100 are configured in an integral structure with the dental bridge body 1000.

[0042] In one embodiment, the barrier body 2100 is configured as a plate-shaped barrier. For example, the plate-shaped barrier has a first barrier surface 2101 and a second barrier surface 2102 facing opposite directions, wherein the first barrier surface 2101 and the second barrier surface 2102 are configured to face the adjacent air bubble chamber 1200 and tooth sleeve cavity 1100, respectively, and at least one of the first barrier surface 2101 and the second barrier surface 2102 is configured as an arc-shaped surface, which can be designed according to the actual situation.

[0043] For example, in one embodiment, the first barrier surface 2101 and the second barrier surface 2102 are both configured as arc-shaped surfaces, as shown in Figure 2 and Figure 3 At least one of the first barrier surface 2101 and the second barrier surface 2102 is recessed to form an arc-shaped surface along the direction from the tooth sleeve cavity 1100 to the air bubble chamber 1200, so that the tooth in the tooth sleeve cavity 1100 can contact the recessed direction of the arc-shaped surface, forming a more stable and larger contact area stress contact state.

[0044] At this time, the arc surface of the first blocking surface 2101 should be in contact with the tooth surface contained in the tooth sleeve cavity 1100, so as to better provide support. In addition, if the target patient is undergoing orthodontic shaping, the blocking assembly 2000 can also configure its structure and position according to the orthodontic plan, so as to provide additional correction to the tooth contained in the tooth sleeve cavity 1100 in combination with the orthodontic plan.

[0045] Therefore, the thickness and position of the above-mentioned blocking assembly 2000 can be freely adjusted, which is equivalent to the thickness and position of each blocking body 2100 in the bridge body 1000. The thickness of each blocking body 2100 is the thickness formed between the first blocking surface 2101 and the second blocking surface 2102 as shown in the figure. Based on the advanced manufacturing method of 3D printing, the thickness of each blocking body 2100 can be adjusted arbitrarily, and the position of each blocking body 2100 can be adjusted arbitrarily, so that the thickness and position of each blocking body 2100 have high flexibility, and the thickness of the blocking assembly 2000 can also be customized in combination with the orthodontic plan. Figure 3

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

[0047] The maximum height of the blocking body 2100 is less than or equal to the maximum sleeve cavity depth of the adjacent tooth sleeve cavity 1100. Moreover, different air bubble chambers 1200 have different maximum chamber depths, and the maximum height of the blocking body 2100 is less than or equal to the maximum chamber depth of the adjacent air bubble chamber 1200. For example, the maximum height of the blocking body 2100 is less than the maximum sleeve cavity depth of the adjacent tooth sleeve cavity 1100, and the maximum height of the blocking body 2100 is less than the maximum chamber depth of the adjacent air bubble chamber 1200, so that the blocking body 2100 can provide sufficient support while minimizing the height and preventing adverse effects on the gums around the teeth.

[0048] The present application provides a dental restoration system, which comprises the bridge structure. Since the specific structure, functional principle and technical effects of the above-mentioned bridge structure have been described in detail in the foregoing, they will not be described here. Any technical content related to the above-mentioned bridge structure can refer to the foregoing description.

[0049] ​Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0050] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications 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.
