A Device for Recording, Positioning and Restoring the Condyle's Position Relationship During Sagittal Splitting of Mandibular Ramus

Abstract

The invention provides a device for recording, locating and recovering the positional relationship of the condyle during mandibular ramus sagittal splitting operation, which includes a position recording component, an upper universal retaining arm, a lower universal retaining arm, a ball and socket structure and a central locking structure. The location record component includes an upper record component and a lower record component. The upper and lower ends of the central locking structure are respectively connected to the end of the upper universal retention arm and the lower universal retention arm, and the other end of the upper universal retention arm is connected by a ball and socket structure for recording the maxillary The upper recording component of the position, and the other end of the lower universal retaining arm is connected to the lower recording component for recording the position of the condyle through a ball and socket structure. The device digitizes the spatial positional relationship of the condyle in the glenoid fossa of the temporal bone, records and reproduces the position of the condyle before and after the operation, has high accuracy and repeatability, and can make the mandibular ramus sagittal split the condyle before and after the operation The position of the process in the temporal bone joint fossa remains unchanged, and the clinical application is accurate and convenient.

Description

technical field [0001] The invention relates to a device for recording, locating and restoring the positional relationship of the condyle in mandibular ramus sagittal splitting operation. Background technique [0002] Skeletal malocclusion is a developmental deformity of the jaw, involving the relative position of the upper and lower jaws, the occlusal relationship of the upper and lower jaws, and the movement status of the bilateral temporomandibular joints. Patients with skeletal malocclusion usually present with abnormal occlusal relationships such as "buck teeth" and "undercovering the sky", as well as facial abnormalities such as depression in the middle of the face, protrusion or retraction of the mandible, etc. Corrective collaborative therapy. Clinical studies have confirmed that the stability of the three-dimensional position of the condyle in the temporal bone glenoid is of great significance to the functional stability of the trinity of "joint movement-jaw positi...
