Problems solved by technology

Traditional implant dentures are usually composed of implants, abutments, and implant crowns. Due to the rigid connection between the above-mentioned components and the osseointegration of the implant and the alveolar bone, stress concentration occurs in the bone tissue around the implant neck. Cause bone resorption and damage to implants and abutments
In addition, due to the lack of elasticity of rigidly connected implant dentures, clinically, the implant crowns of patients are lower than normal natural teeth, resulting in inaccurate bites when patients bite lightly, and contact only when patients bite hard. Even so, it is still unavoidable stress concentration problem

Embodiment Construction

[0023] The implant denture with spring damper telescopic abutment provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Such as Figure 1-Figure 13 As shown, the implant denture with spring damper telescopic abutment provided by the present invention includes implant 1, lower telescopic abutment 2, upper telescopic abutment 3, fixing screw 4, damper 5, abutment cover 6 and dental implant Crown 7; wherein, the implant 1 is a cylindrical structure, external threads are formed on the outer peripheral surface, and are implanted into the bone tissue in the patient's oral cavity by using the external threads, and the middle part of the top surface is depressed to form a center Hole 1-1, the middle part of the bottom surface of the central hole 1-1 is recessed downwards to form a screw hole 1-2; the middle part of the lower telescopic abutment 2 is formed with an axial through hole 2-1, and t...

Abstract

An implant denture with a spring-damper telescopic abutment. It includes an implant, a lower telescopic abutment, an upper telescopic abutment, set screws, a damper, an abutment cover and an implant crown; the implant denture with a spring damper telescopic abutment provided by the present invention has the following beneficial effects: The abutment overcomes the defects of the traditional abutment and plays a buffer role in the occlusal force. Clinically, the damping value of the natural teeth and implants in the patient's mouth can be measured, and an appropriate damper can be selected to simulate the natural teeth to the greatest extent, so as to achieve the best occlusal contact and occlusal force.

Description

technical field [0001] The invention belongs to the technical field of denture structures, in particular to an implant denture with a spring damper telescopic abutment. Background technique [0002] In stomatology, implant restorations made after partial or complete tooth loss of upper and lower jaw teeth are collectively referred to as implant dentures. Traditional implant dentures are usually composed of implants, abutments, and implant crowns. Due to the rigid connection between the above-mentioned components and the osseointegration of the implant and the alveolar bone, stress concentration occurs in the bone tissue around the implant neck. Cause bone resorption and damage to implants and abutments. In addition, due to the lack of elasticity of rigidly connected implant dentures, clinically, the implant crowns of patients are lower than normal natural teeth, resulting in inaccurate bites when patients bite lightly, and contact only when patients bite hard. Even so, it i...
