Problems solved by technology

While ensuring that the occlusal plane is parallel to the orbito-auricular plane, it is still necessary to ensure that the midline of the maxillary dentition is consistent with the midline of the face, otherwise the postoperative appearance of the patient will be greatly sacrificed

Abstract

The invention provides a three-dimensional precise locator for maxillary bone, which relates to the field of oral medical instruments. The locator includes a cantilever, a connecting shaft, a spacer and an elastic cap. The threaded shaft is sequentially fitted with two cantilever arms and a spacer from bottom to top. The elastic cap is arranged above the spacer and connected with the threaded shaft; The positioning cylinder is connected by thread, the central axis is set in the outer casing of the central axis, and the sliding rod and the universal head are arranged in the limit tube from the head end to the tail end; tighten the elastic cap downward, the central axis remains in the original state, and the gasket and the outer sleeve of the center shaft move downward and the slide bar and the universal head move outward, and the various parts of the final positioner are fixed and cannot move. The present invention also provides an orbital plane indicator and socket for use with the maxillary three-dimensional precise locator. The invention can ensure that the maxillary occlusal plane is parallel to the orbito-auricular plane, and that the maxillary dentition midline is consistent with the facial midline, thereby avoiding the problem of deflection of the occlusal plane and the upper tooth midline after operation.

Description

technical field [0001] The invention relates to the field of oral medical instruments, in particular to a three-dimensional precise locator for maxillary bone. Background technique [0002] Skeletal dentofacial deformity is a kind of abnormal maxillofacial shape and occlusal relationship disorder caused by the growth and development of maxillofacial bones. The positional relationship is out of balance. At present, the main treatment method for adults with moderate and severe skeletal dento-maxillofacial deformities is orthodontics-orthognathic combined orthodontics, that is, to correct the abnormal jaw position relationship through orthognathic surgery, and to achieve a good occlusion through orthodontic treatment. In order to achieve the goal of diagnosis and treatment, it is necessary to accurately locate the relationship between the upper and lower jaws during orthognathic surgery, adjust the abnormal jaw position to the direction and position designed before surgery, an...
