Titanium alloy maxillary alveolar bone osteotomy guide plate generated through three-dimensional printing technology

Abstract

The invention relates to the technical field of medical treatment, in particular to a titanium alloy maxillary alveolar bone osteotomy guide plate generated through a three-dimensional printing technology. According to the titanium alloy maxillary alveolar bone osteotomy guide plate generated through the three-dimensional printing technology, through a three-dimensional printing method, a reverse-concave area can be avoided in design software before the surgery, a protruding blocking area is finished in advance, and smooth wearing of the guide plate can be guaranteed; an osteotomy guide grooveis formed in the surface of a main guide plate body, so that the main guide plate better fits the surface of the maxillary alveolar bone of the human body, retention holes are also formed in the surface of the osteotomy guide plate, people conveniently carry on retention through fixing nails, the position of the main guide plate body keeps stable and invariant, and therefore the best retention effect can be obtained; an osteotomy groove is formed in the surface of a connection body forming the main guide plate body, doctors carry on precise osteotomy conveniently, the osteotomy efficiency isimproved, and the important tissue structure is prevented from being injured in the surgery.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a titanium alloy maxillary alveolar bone osteotomy guide plate generated by three-dimensional printing technology. Background technique [0002] At present, the ideal treatment method for patients with dentition defects and edentulousness is oral implant restoration. Congenital diseases, acquired diseases, or aging will cause uneven absorption of the maxillary bone, especially the vertical absorption of the maxillary bilateral molar area, resulting in high, steep and thin anterior maxillary teeth and flat posterior teeth. . In order to achieve a good full-mouth implant fixation or movable restoration effect, it is necessary to flatten the high and steep alveolar ridge and part of the alveolar bone in the maxillary anterior teeth. Because the important anatomical structures of the maxilla are near the operation area, such as the maxillary sinus and nasal floor, the osteotomy op...

AI Technical Summary

Problems solved by technology

If the amount of osteotomy is too large, it will cause unnecessary damage to the patient, and there is a risk of insufficient implant height and poor prognosis; The risk of damaging important anatomical structures; the direction of osteotomy is not good, and it is impossible to form a good postoperative dental arch shape and obtain a good implant restoration effect

[0004] Some scholars also try to use resin materials to make guide plates for osteotomy operations, but resin material guide plates are often very thick, large in size, require more operating space, poorly fit with tissues, and are relatively brittle and easy to break

[0005] In the past, surgical guides were often prepared by making an impression, pouring plaster, and then preparing the guide on the plaster model. This is based on the soft tissue support guide. The soft tissue has a certain degree of tolerance and cannot be fixed stably.
