Embodiment 1

[0018] Embodiment 1: Dimensional parameters of a typical structure locator

[0019] The maxillary horizontal positioning rod 15 is a cuboid with a length of 8.0 cm, a width of 2.0 mm, and a height of 2.0 mm; the upper jaw horizontal positioning rod 15 is a trapezoid with an upper bottom of 0.5 mm, a lower bottom of 1.0 mm, a height of 0.5 mm, and a thickness of 2.0 mm. Plug body 19; maxillary midline positioning rod 17 is a cuboid with a length of 5.0 cm, a width of 2.0 mm, and a height of 2.0 mm; the upper part of the maxillary midline positioning rod 17 is a trapezoidal bolt with an upper bottom of 0.5 mm, a lower bottom of 1.0 mm, and a height of 0.5 mm. Road 18, the length of the trapezoidal tie road 18 is consistent with the length of the maxillary midline positioning rod 17; the trapezoidal plug body 19 on the maxillary horizontal positioning rod 15 can slide along the trapezoidal fastening road 18 on the maxillary midline positioning rod 17;

Embodiment 2

[0025] Embodiment 2: Application of the specific operation method of the locator of the present invention

[0026] The unsatisfactory facial shape of the patient requires surgical treatment. The main problem is that the maxilla is deviated to the left and the left side of the maxilla is underdeveloped. In combination with preoperative orthodontics, our surgical plan is: treat the deviation and For the asymmetrically developed maxilla, move the maxilla to the right according to the design so that the midsagittal line of the maxilla is consistent with the midsagittal plane of the craniomaxillofacial region, and at the same time make the occlusal plane of the maxillary dentition parallel to the line connecting the pupils of the eyes, so that Restore the correct and ideal face shape of the patient. Specific methods of applying the Maxillary Movement Pinpointer:

[0027] 1. After surgically making the intermediate occlusal plate according to the conventional orthognathic surgery m...

Abstract

The invention discloses a maxilla movement precise positioner, and belongs to the technical field of clinical medicine. The main body part of the maxilla movement precise positioner is composed of aninternal positioning element, a middle positioning element and an external positioning element; the middle positioning element of the maxilla movement precise positioner is fixed to a middle biteplateby means of the internal positioning element of the maxilla movement precise positioner before operation, the middle positioning element and the external positioning element of a maxilla midline precise positioner are magnetically fixed together during operation, and when the midline marker of the facial midline indicating rod of the external positioning element is in line with the median sagittal plane of the craniofacial region, and the midline marker of the facial horizontal indicating rod of the external positioning element is in line with the connection line of the pupils of both eyes, abone block is fixed with a titanium plate, and then the maxilla movement precise positioner is removed. Application of the maxilla movement precise positioner provides a more precise and scientific guarantee for precise movement and positioning of the maxilla bone block in the transverse direction in the Lefort I type osteotomy.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine, and in particular relates to a maxillary movement precise locator used in maxillary Lefort I type osteotomy to ensure the precise positioning of maxillary bone blocks in the process of moving left and right. Background technique [0002] Lefort type I maxillary osteotomy is a surgical method for correcting abnormalities in the three-dimensional directions of the maxilla, including overdevelopment, underdevelopment and asymmetry of the maxilla. To correct the abnormality of the three-dimensional direction of the maxilla, it is necessary to adjust the free bone mass of the maxilla in the three-dimensional direction through surgery to achieve the ideal position. However, according to the preoperative design plan during the operation, using the conventional temporomandibular joint positioning method, there are common errors in the precise movement and positioning of the maxillary free bone ...
