Background
Currently, an ideal treatment for patients with dentition defects is oral implant restoration. Congenital diseases, acquired diseases, or natural aging may cause uneven absorption of the mandible, especially marked vertical absorption of the mandible, failing to complete implant repair. In order to obtain good full-mouth implant fixation or activity repair effect, the treatment can be completed by adopting a Sandwich bone grafting method. Because the important anatomy of the mandible is in the vicinity of the operative area, such as the restrictions of the chin hole, the nerve blood vessel bundle of the lower alveolus, etc., the osteotomy requires that the important anatomy is not damaged, and that a sufficient mandible height and width is obtained, thereby ensuring safe implementation of the implant surgery and long-term safety and stability.
In the prior art, most of the treatment methods are that an operator subjectively judges the osteotomy position, the osteotomy path is not clear, and the chin nerve, the lower alveolar nerve blood vessel bundles and the like can be damaged; too large, insufficient, or deviation of osteotomy direction may also occur. The bone cutting amount is too large, unnecessary damage is caused to patients, and the risk of insufficient planting height and reduced repair strength exists; the osteotomy quantity is too small, and the osteotomy or grinding is needed to be repeated for a plurality of times, so that the operation time, the risk of bleeding in the operation and damaging important anatomical structures are increased; the osteotomy direction is not good, and a better postoperative dental arch form and a good planting and repairing effect can not be formed.
After the osteotomy is completed, the traditional fixation is based on the experience of doctors, and the titanium plate cannot be pre-bent and fixed according to the best repair requirement, so that the fixation position is inaccurate, the pre-bent titanium plate is needed in the operation, the operation time is long, and the wound is large. When the titanium plate is fixed by using the titanium nails, the blind method of beating titanium nails can cause damage to important structures such as nerves and blood vessels.
