Description
Technical Field
The invention relates to the field of titanium mesh manufacturing, in particular to a method for manufacturing a titanium mesh for alveolar bone defect.
Background
Local large-area alveolar ridge bone defect reconstruction and bone regeneration are always difficult points for oral implant repair, and when the alveolar bone is absorbed in the horizontal direction and the vertical direction at the same time, three-dimensional reconstruction is more difficult. In 2001, Maiorana et al (1) applied a titanium mesh and a bone powder material (the ratio of autologous ilium to inorganic bovine bone is 1: 1) to perform bone amplification, and the titanium mesh is proved to be effective in human alveolar ridge bone mass amplification from clinical and histological levels for the first time. The study showed that: by using the titanium mesh as a barrier for bone regeneration, the bone increment can reach 10mm in the vertical direction and the horizontal direction, which is far larger than that under the condition of not using the titanium mesh as a support, and the long-term bone absorption capacity is smaller than that of the case without using the titanium mesh (2-4).
Nowadays, titanium mesh is often used in cases where bone defect is severe and rigid support is required to achieve large area bone regeneration due to its good mechanical properties. In the clinical bone grafting operation process, the finished titanium mesh needs to be trimmed and shaped so as to form the appearance of the joint bone defect, and meanwhile, the titanium mesh is also ensured to be overlapped with the periphery and the bone in partial area so as to fix the membrane nail. In clinical application, doctors are confronted with various bone defects, and not all finished titanium meshes can completely cover the range of the bone defects after trimming, so that the operation effect is poor. (5) A titanium mesh that does not fit well against the bone wall will cause the wound to split, resulting in exposure of the titanium mesh. Partial clinical case studies have shown that the incidence of titanium mesh exposure is as high as 50%. On the other hand, in the face of irregular bone defect appearance, the trimming of the titanium mesh is very complicated, the operation difficulty is high, long intraoperative time (6) is occupied, and the influence on the operative region of a patient and the postoperative recovery are both adversely affected.
Currently, digital-Aided Design (CAD) has been used to reconstruct the bone defect morphology from CBCT data of a patient and to Design the bone graft and the shape of the corresponding support material based on the bone defect range. Digital-to-analog Manufacturing (CAM) can be implemented by metal printing. Research shows that the personalized titanium net manufactured by metal printing is stable in form, sufficient in strength, effective and safe in clinical use (6-8). The only problem is that the contact area of the titanium mesh and the basal bone is limited, the positioning error is large, the inosculation degree between the titanium mesh and the dentition or the basal bone is deviated, and the proper fixing position is difficult to determine in the operation. Therefore, the positioning accuracy of the titanium net is improved, the positioning error of the titanium net is avoided, and the convenience of using the titanium net can be further improved. The CAD/CAM 3D printing personalized medical osteogenesis titanium net which is researched and developed independently is not available in China. There is also no titanium mesh aid with precise positioning capability.
