Problems solved by technology

Because in clinical applications, doctors are faced with various bone defects, not all finished titanium meshes can completely cover the bone defects after trimming, resulting in poor surgical results
(5) The titanium mesh that cannot fit well with the bone wall will cause the wound to crack, resulting in the exposure of the titanium mesh
There is also no titanium mesh auxiliary tool with precise positioning capabilities

Abstract

The invention relates to a titanium mesh manufacturing method for the alveolar bone defect, which comprises the steps of 1, synthesizing 3D model data of the dentition and jaw according to dentition data and jaw data; 2, generating three-dimensional data of a titanium mesh covering a bone defect structure according to the bone defect structure; 3, generating a positioning wing, and generating dataof the positioning wind connecting a natural tooth adjacent to the bone defect position and the titanium mesh according to the three-dimensional data of the titanium mesh and the 3D model data; 4, determining positioning holes used for fixing the titanium mesh on the jaw according to the three-dimensional data of the titanium mesh; and 5, printing the titanium mesh. The position matching betweenthe titanium mesh and the adjacent natural tooth is realized due to the setting of the positioning wing, the installation location of the titanium mesh can be positioned according to the positioning wing when the titanium mesh is installed so as to enable the titanium mesh to be accurately fixed at the predetermined location.

Description

technical field [0001] The invention relates to the field of making titanium mesh, in particular to a method for making titanium mesh for alveolar bone defect. Background technique [0002] The reconstruction and bone regeneration of large local alveolar ridge defects has always been a difficult point in oral implant restoration. When the alveolar bone resorbs in the horizontal and vertical directions at the same time, three-dimensional reconstruction is even more difficult. In 2001, Maiorana et al. (1) applied titanium mesh and bone powder materials (the ratio of autologous iliac crest: inorganic bovine bone was 1:1) for bone augmentation, and proved for the first time that titanium mesh has a positive effect on human alveolar bone from clinical and histological levels. Volume expansion is effective. Studies have shown that using titanium mesh as a barrier for bone regeneration, bone augmentation can reach 10mm vertically and horizontally, which is much greater than that w...
