Description

Technical Field

[0001] This utility model relates to the field of oral restoration technology, specifically to a 3D-printed implant model for an edentulous jaw. Background Technology

[0002] In prosthodontics, treatment for edentulous patients includes traditional complete dentures and modern dental implant techniques. With the development of 3D printing technology, not only has production time been shortened, but the fit between implants and the patient's bone has also improved, thus enhancing treatment outcomes. Therefore, its application in prosthodontics is becoming increasingly widespread.

[0003] A major problem with existing 3D printed implant models is that most existing models fail to fully consider the specific morphological differences of the upper and lower jawbones in edentulous patients, which may lead to problems such as unsuitability or instability of the implants in actual applications. Furthermore, traditional designs often lack consideration for the supporting structures of the surrounding soft tissues, which further affects the stability and comfort of the implants. Utility Model Content

[0004] The purpose of this invention is to provide a 3D-printed implant model for edentulous jaws, in order to solve the problems of poor adaptability and insufficient stability of current 3D-printed implant models mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 3D-printed implant model for an edentulous jaw, comprising a jaw simulation body, wherein the jaw simulation body is provided with an occlusal contact layer, a bionic bone layer and a base adapter layer from top to bottom, the three being fixedly connected by an integral molding process, the bionic bone layer having multiple implant mounting cavities embedded inside, and the base adapter layer having multiple adjustable feet at its bottom, the adjustable feet being connected to the base adapter layer by rotating screws, and the jaw simulation body having occlusal guide grooves on both sides, with occlusal positioning blocks embedded in the occlusal guide grooves.

[0006] Preferably, the occlusal contact layer has an arc-shaped surface that smoothly transitions to the upper surface of the biomimetic bone layer, and the thickness of the biomimetic bone layer is uniformly distributed.

[0007] Preferably, the implant mounting cavity is cylindrical, and its inner wall is provided with multiple annular limiting grooves, which are evenly distributed along the axial direction of the implant mounting cavity.

[0008] Preferably, the adjusting leg is a hollow cylindrical structure with a threaded hole at its top, and the end of the rotating screw is connected to the threaded hole on the adjusting leg.

[0009] Preferably, the bite guide groove is a U-shaped groove with guide slopes on both sides, and the bite positioning block is a wedge-shaped structure with anti-slip texture on its surface.

[0010] Preferably, the outer surface of the jaw simulator is fitted with a soft tissue simulation layer, and the soft tissue simulation layer covers the outer surface of the occlusal contact layer and part of the biomimetic bone layer.

[0011] Compared with existing technologies, the beneficial effects of this invention are: the 3D-printed edentulous replacement implant model has a reasonable structural design and good adaptability, effectively improving the stability and wearing comfort of the implant. Through the integrated structural design of the occlusal contact layer and the biomimetic bone layer, the implant model realistically reproduces the patient's oral anatomy, improving the accuracy of implant placement angle and position. The limiting groove set within the implant mounting cavity enables precise positioning and stable fitting of the implant, preventing displacement or loosening during preoperative simulation. Combined with the design of adjustable support legs and rotating screws, the model can be height-adjusted and leveled as needed during use, enhancing operational stability.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: a 3D-printed implant model for an edentulous jaw, including a jaw simulation body 1. The jaw simulation body 1 has, from top to bottom, a biting contact layer 101, a bionic bone layer 102, and a base adapter layer 103, which are fixedly connected by an integral molding process. Multiple implant mounting cavities 2 are embedded inside the bionic bone layer 102, and each implant mounting cavity 2 has a limiting groove for positioning the implant. The base adapter layer 103 has multiple adjustable feet 3 at its bottom, which are connected to the base adapter layer 103 via a rotating screw 301. Furthermore, the jaw simulation body 1 has biting guide grooves 4 on both sides, with biting positioning blocks 5 embedded within the biting guide grooves 4. This structure, through the cooperation of the adjustable feet 3 and the rotating screw 301, allows the model to be adjusted according to different... The experimental platform or simulation environment undergoes fine-tuning and angle adaptation to ensure that the jaw simulation body 1 maintains a stable reference plane during operation. Based on this, the occlusal guide groove 4 and the occlusal positioning block 5 provide guidance during the alignment of the upper and lower jaws, ensuring the accuracy of the occlusal relationship and preventing the spatial layout of the implant from being affected by model misalignment. Simultaneously, the implant installation cavity 2 in the biomimetic bone layer 102, combined with the limiting groove design, enables precise implant insertion and axial fixation, avoiding deviation or depth errors during installation. The synergistic work of these structures makes the preoperative simulation more closely resemble the actual clinical situation, solving the problems of low implant positioning accuracy, insufficient occlusal relationship reproduction, and poor adaptability in existing edentulous jaw models. This design improves the reliability and clinical guidance value of implant simulation. The occlusal contact layer 101 has an arc-shaped surface that smoothly transitions to the upper surface of the biomimetic bone layer 102, with a uniform thickness. This structure allows the arc-shaped surface of the occlusal contact layer 101 to more realistically simulate the contact state of the patient's upper and lower teeth during occlusion. This not only improves the overall anatomical morphology reproduction of the model but also helps to achieve a more uniform stress distribution when simulating occlusal force transmission. Simultaneously, the uniform thickness of the biomimetic bone layer 102 ensures consistent support for the implant mounting cavity 2 at different locations, avoiding force deviations or simulation distortions caused by uneven material thickness in certain areas. This improves the accuracy of preoperative assessment and operation. To ensure stability during the procedure, the implant mounting cavity 2 is cylindrical, with multiple annular limiting grooves on its inner wall. These grooves are evenly spaced axially along the implant mounting cavity 2. This structure matches the shape of conventional implants, facilitating standardized operation and adapting to implants of different sizes. The annular limiting grooves on its inner wall provide multi-level positioning and engagement during implant insertion, enhancing the implant's fit stability in the model and preventing slippage or displacement during simulation. Simultaneously, the limiting grooves at different positions allow for precise control of the implantation depth. The adjusting leg 3 is a hollow cylindrical structure with a threaded hole at its top, and the end of the rotating screw 301 engages with the threaded hole on the adjusting leg 3.This structure, through the cooperation of hollow cylindrical adjusting feet 3 and rotating screw 301, allows for flexible adjustment of the model's bottom height and level, ensuring the jaw simulator 1 maintains a stable reference plane during use. Anti-slip pads enhance the friction of the support surface, preventing the model from sliding or shifting during operation. The occlusal guide groove 4 is a U-shaped groove with guide ramps on both sides, and the occlusal positioning block 5 is a wedge-shaped structure with anti-slip textures on its surface. This structure, through the cooperation of the U-shaped occlusal guide groove 4 and the wedge-shaped occlusal positioning block 5, utilizes the guide ramps to ensure proper alignment of the upper and lower jaw simulators. The automatic guidance and precise fitting during the process, along with the anti-slip texture, enhance the contact stability between the positioning block and the groove, preventing misalignment and slippage, thus ensuring accurate restoration of the occlusal relationship. The outer surface of the jaw simulation body 1 is fitted with a soft tissue simulation layer 6, which covers the outer surface of the occlusal contact layer 101 and part of the biomimetic bone layer 102. This soft tissue simulation layer 6 effectively simulates the morphology and support relationship of the soft tissues in the oral cavity of edentulous patients, making the entire implant model closer to the real oral environment in appearance and feel. This facilitates more intuitive and clinically relevant preoperative assessments and practice for doctors.

[0016] Working principle: When using the edentulous 3D printed substitute implant model, the jaw simulation body 1 is first placed on the operating platform through the adjustable support leg 3 at the bottom of the base adapter layer 103. The height and level of the model are then finely adjusted by rotating the screw 301 to ensure the stability of the model's reference plane. Subsequently, according to the alignment requirements of the upper and lower jaws, the occlusal positioning block 5 is slid into and fitted into place along the U-shaped groove of the occlusal guide groove 4. Its wedge-shaped structure and guide slope are used to achieve precise docking of the upper and lower jaw simulation bodies. On this basis, the implant is inserted into the implant installation cavity 2 inside the bionic bone layer 102 according to the preset position, and the outer wall of the implant is fitted into the limiting groove. At the same time, during the simulation process, the soft tissue simulation layer 6 covers the occlusal contact layer 101 and part of the outer side of the bionic bone layer 102 to help restore the spatial relationship of the soft and hard tissues of the oral cavity, thereby completing a series of tasks.

[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
