Embodiment 1

[0042] Figure 5 Schematic diagram of bone augmentation during implantation.

[0043] Figure 5 a) When the width of the bone is not enough, the implant placement causes part of the implant to be exposed or the residual bone wall is too thin, which is easy to be absorbed, cover the surface of the exposed implant or the surface of the thin residual bone wall with absorbable magnesium alloy barrier film, and in the barrier film gingival The side or mesio-distal are fixed with retaining screws, and the coronal side of the barrier film is placed on the edge of the implant, or it completely covers the surface of the implant and falls on the lingual edge, which can be fixed with cover screws, between the barrier film and the implant filled with bone material.

[0044] Figure 5 b and Figure 5 c is that when the bone width and bone height are insufficient, the implant cannot be fully embedded in the bone, resulting in the exposure of the upper end of the implant. Pre-formed or n...

[0046] Image 6 and Figure 7 Respectively, the schematic diagram of the application of the extraction socket site preservation after tooth extraction, and the schematic diagram of horizontal or vertical bone augmentation repair.

[0047] Its usage is the same as Example 1

Embodiment 3

[0049] Figure 8 It is a schematic diagram of periodontal guided tissue regeneration repair;

[0050] Figure 8 a: After the basic treatment of the periodontal pocket, the periodontal pocket is filled or not filled with bone graft material, and the opening of the periodontal pocket is covered with a barrier film, which can be fixed with or without fixation, and tightly sutured. Figure 8 b is to trim the barrier film to an appropriate size according to the size of the periodontal pocket, and pack the barrier film in the periodontal pocket, which can be retained by the elasticity of the barrier film. In the process of degradation of magnesium alloy, an alkaline environment is generated, which is beneficial to the control of periodontal microorganisms, promotes the recovery of periodontal infection, and promotes bone regeneration, which makes up for the gap that the current GTR membrane materials do not have bacteriostatic and osteogenic effects. .

Abstract

The invention discloses an absorbable magnesium alloy repairing system used for oral cavity guide bone / tissue regeneration and belongs to the technical field of planting systems. A magnesium alloy containing silver is used for the repairing system. A supporting nail is additionally arranged in the repairing system, the whole supporting nail is in a nail shape, a protrusive cylinder structure which is arranged in the center of the upper surface of a supporting wing is a penetrating membrane, the lower end portion of a nail body is provided with a supporting nail thread, a barrier membrane can be better supported, and the repairing effect is improved.

Description

technical field [0001] The invention relates to an absorbable magnesium alloy repair system for guiding bone / tissue regeneration in the oral cavity, and belongs to the technical field of implant systems. Background technique [0002] With the development of materials and medical technology, the application of oral implants has become more and more extensive, but in practical applications, problems such as insufficient bone mass (height and thickness) of patients and poor implant retention are often encountered. According to the characteristics of bone and soft tissue growth, Guide Bone Regeneration (GBR) or / and Guide Tissue Regeneration (GTR) technology is mostly used for bone expansion, that is, the use of fibroblasts and other cells with high migration speed and osteogenesis Due to the slow migration speed of cells, the biofilm made of biomaterials is placed between the soft and hard tissues of the oral cavity, thereby preventing fibroblasts from growing into the bone defe...
