Description

Titanium alloy Sandwich bone grafting retention titanium plate generated by three-dimensional printing technology

Technical Field

The utility model relates to the field of medical technology, in particular to a titanium alloy Sandwich bone grafting retention titanium plate generated by a three-dimensional printing technology.

Background

At present, the ideal treatment method for patients with dentition defects and dentition loss is oral implant restoration. Congenital diseases, acquired diseases, or natural aging may cause uneven absorption of the mandible, especially the mandibular alveolar bone is absorbed in a vertical direction significantly, failing to complete implant repair. In order to obtain good full-mouth implant fixation or movable repair effect, the treatment can be completed by adopting a Sandwich bone grafting method. Because the important anatomical structures of the lower jaw are limited near the operation area, such as the chin hole, the inferior alveolar neurovascular bundle, and the like, the osteotomy operation requires neither damage to the important anatomical structures nor acquisition of a sufficient height and width of the lower jaw bone, thereby ensuring safe implementation and long-term safe stability of the implant operation.

Most of the previous treatment methods are that an operator subjectively judges an osteotomy part, an osteotomy path is unclear, and the mental nerve, the inferior alveolar nerve vascular bundle and the like can be damaged; too large or insufficient osteotomy amount, deviation in osteotomy direction, and the like may occur. The bone cutting amount is too large, unnecessary damage can be caused to a patient, the planting height is insufficient, and the repairing strength is reduced; the bone cutting amount is too small, repeated bone cutting or grinding is needed, and the risks of operation time, bleeding during operation and damage to important anatomical structures are increased; the direction of osteotomy is not good, and good postoperative dental arch form and good planting and repairing effect can not be formed.

After the osteotomy is completed, the previous fixation is performed by the experience of a doctor, and the titanium plate cannot be fixed in a pre-bending way according to the optimal repair requirement, so that the fixation position is not accurate, the titanium plate needs to be pre-bent in the operation, the operation time is long, and the wound is large. When the titanium plate is fixed by the titanium nail, important structures such as nerves, blood vessels and the like can be damaged by blind-method titanium nail driving.
