Manufacturing method and using method of front tooth occlussion blocker based on 3D printing

Abstract

The invention discloses a manufacturing method and a using method of a front tooth occlussion blocker based on 3D printing, and relates to a preparation guiding piece of at least one tooth used for dental restoration preparation. The manufacturing method of the front tooth occlussion blocker based on 3D printing comprises the following steps: (1) obtaining a digital model; (2) constructing an occlussion guiding plate; (3) positioning the occlussion guiding plate; (4) adjusting and amending a rudimentary model to obtain an overall model after fine virtual adjustment; (5) carrying out 3D printing, and carrying out subsequent processing according to requirements after the printing is completed. According to the scheme provided in the invention, the blocker does not need to be manufactured directly in the mouth of a patient, solidified self-curing resin does not need to consume much time to be worn into a plane, the operation is simple, the method is easy to grasp, and the materials are saved; occlussion opening distance is accurately controlled in the design process, the phenomena that the separation distance of teeth is too large and the condyle is free of a centric relation are avoided, the lower jaw can freely slide into the centric relation, and repeated adjustment is not needed.

Description

technical field [0001] The present invention relates to a preparation guide configured for at least one tooth for oral restoration preparation, and in particular to a method of manufacturing an anterior occlusal blocker based on 3D printing and a method of use thereof. Background technique [0002] The process of dental treatment often involves occlusal reconstruction, that is, the positional relationship of the lower jaw relative to the upper jaw. In 1979, Dawson proposed that when the condyle is at the uppermost and anterior position of the articular fossa, the relationship between the mandible and the mandible becomes a centric relationship. This position belongs to physical positioning, the position is constant, the repeatability is good, and it is easy to be recorded. Since then, many basic and clinical studies have proved that the median position is the ideal jaw position for oral restoration, temporomandibular joint treatment and orthodontic treatment. Of all the tec...

However, both methods have certain disadvantages

The direct method is complicated to operate and takes a long time in the chair. It is difficult for the patient to control the separation distance of the posterior teeth in the process of closed occlusal. The failure rate is high and it is difficult to master.

The finished anterior occlusal blocker needs to be fixed on the central incisor with self-curing resin. First, it is difficult to ensure that the plane below the blocker is in line with the upper jaw after the resin is cured. The planes are parallel, and secondly, it may increase the separation distance of the posterior teeth, making the condyle out of the central relationship
