Pluggable gothic arch tracing system used for dental restoration and method thereof

Abstract

The invention discloses a pluggable gothic arch tracing system used for dental restoration and a method thereof. The pluggable gothic arch tracing system comprises an upper jaw arch plate and a lowerjaw arch plate, the upper jaw arch plate is in a U-shaped structure, and a T-shaped upper jaw tracing plate is embedded in an inner side of the upper jaw arch plate; the lower jaw arch plate is in a U-shaped structure, a handle is inserted at a front end of the lower jaw arch plate 3, a T-shaped lower jaw arch plate is embedded in the inner side of the lower jaw arch plate 3, and a tracing needleis connected with the lower jaw arch plate through screw thread. According to the tracing system, a front tooth zone tongue side avoidance groove is arranged at a front end of the upper jaw arch plate, a wax rim space is reserved, and the tracing system is in favor of recording and transferring fullness of a maxillary anterior region through wax addition or reduction during dental restoration forpatient. The handle is a pluggable type, is inserted at a channel section of the lower jaw arch plate while mold taking and facebow using, and the can be removed while the aesthetics information is recorded by wax rim. According to the invention, a fork and a bite silicone rubber are not used for facebow transfer, and an upper lip is not interfered while aesthetics information is transferred.

Description

technical field [0001] The invention relates to the technical field of oral medical devices, in particular to a tracing system and method of a plug-in Gothic bow for oral restoration. Background technique [0002] When the patient has a large number of missing teeth, the prosthodontist needs to obtain the positional relationship between the patient's upper jaw and lower jaw, upper jaw and head, and transfer it to a mechanical device that simulates the movement of the human jaw—— on the shelf. [0003] Generally, we assume that the head is fixed, determine the positional relationship between the head and the upper jaw through the face bow, and determine the relationship between the upper jaw and the lower jaw through the Gothic bow, so as to complete the entire transfer process. There are currently two types of gothic archgraphs: handle and handleless, for edentulous and edentulous patients in the anterior region, respectively. The gothic bow tracer with a handle is easy t...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art. The purpose is to provide a tracing system and method of a plug-in type Gothic bow for oral restoration, which solves the problem that the Gothic bow tracing device with a handle is easy to hold and can be directly connected with The parts of the facebow are connected, and the relationship between the upper jaw and the head can be transferred without using the jaw fork and occlusal silicone rubber. However, the handle often provokes the upper lip, making it impossible for the doctor to judge the fullness of the patient's upper lip, and thus unable to judge the patient's future anterior teeth. the location of the problem
