A universal prefabricated bone ring for oral implant

Abstract

The invention discloses a universal prefabricated bone ring for oral implant which belongs to the field of medical instruments and is suitable for implant cases with bone increment. The bone ring is in a ring shape, wherein a guide hole is arranged at the center of the bone ring, and the outer diameter of the bone ring is in the range of 4.5-8.5 mm, guide hole diameter is in the range of 1-3.4 mm,the height range is 2-7 mm. Bone rings are made from xenogeneic bone, allogeneic bone, or synthetic materials. The implant was implanted into the implant socket through the through-hole, and the bonering was fixed in the implant bed, and the implant and bone incremental operation are completed simultaneously. The bone ring adopts a guide hole design, and the step-by-step reaming hole can be adapted to different planting systems and models; The height, outer diameter and thickness of the bone ring can be selected flexibly, which ensures that the prefabricated bone ring has stronger adaptability and versatility.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a general preformed bone ring which needs to use bone augmentation technology in oral implant treatment. Background technique [0002] Dental implants are one of the most important means of fixed denture restoration today. Dental implants require sufficient bone mass in the area. Unfortunately, 40%-60% of patients with missing teeth have bone defects. For these patients, how to use bone? Incremental technology to solve the problem of bone defects has become the key to successful implantation. [0003] There are many clinical bone augmentation techniques commonly used, and there are different options for different types of bone defects. Among them, the ring-shaped bone graft technology has received widespread attention in just over ten years since its invention, because it has many advantages: 1. The ring-shaped bone block can effectively maintain the three-dimensiona...

AI Technical Summary

Problems solved by technology

However, there will be major defects in actual use: 1. The diameter of the through hole is large, which directly corresponds to the diameter of the implant. It is difficult to correspond to hundreds of implant systems and models at present. Due to mechanical errors, stable fit cannot be achieved; 2. The outer diameter of the bone ring of this utility model is large, but the actual bone defects vary widely in clinical practice, and the defect range is often less than 7mm. If the outer diameter is too large, it cannot meet the needs of different bone defects; 3. The thickness of the ring is fixed at 2mm, and the selection of one implant type can only repair the fixed size bone defect, which is obviously inconsistent with the actual clinical situation
