Problems solved by technology

However, the designed restoration will cause occlusal interference, especially when the non-central occlusal interference is encountered. The existing technical means is usually that the doctor adjusts and grinds the opposing teeth based on experience. This method requires the dentist to have rich experience, and the doctor is adjusting During the grinding process, continuous inspection is required, and patients must actively cooperate accordingly, so it will consume a lot of energy and time for doctors, and patients will also experience poor experience due to continuous cooperation, so the status quo needs to be changed

Abstract

The invention relates to a method for making a blending guide plate, comprising the following steps: using a three-dimensional scanning technology to obtain a three-dimensional model of the patient's upper jaw and a three-dimensional model of the lower jaw, and obtaining the three-dimensional positional relationship of the different states of the upper and lower jaw dentition; The three-dimensional position relationship obtains the occlusal contact relationship of the patient in different states; the mandibular position of the patient in different states is collected in the three-dimensional software, and based on this, the restoration shape of the maxillary anterior teeth is designed to form a diagnostic model; based on the diagnostic model, the three-dimensional The ideal restorative effect of the patient's upper anterior teeth and its positional relationship with the mandibular dentition in different states were obtained through the design; by adjusting the shape of the incisal end of the mandibular anterior teeth to avoid occlusal interference, based on the adjusted shape of the mandibular anterior The guide plate is combined; the diagnostic model and the guide plate are obtained by three-dimensional printing. The blending guide plate made by the invention can quickly and accurately adjust and grind tooth tissue.

Description

technical field [0001] The invention relates to the technical field of medical machinery manufacturing, in particular to a method for manufacturing a blending guide plate. Background technique [0002] The purpose of oral cosmetic surgery is to improve the smile, which involves comprehensive medical treatment of teeth and gums, especially the upper front teeth. The first principle that needs to be determined is that beauty should be based on health, so unhealthy beauty is not the goal of oral beauty. The beauty of teeth mainly improves alignment, color and shape. However, the designed restoration will cause occlusal interference, especially when the non-central occlusal interference is encountered. The existing technical means is usually that the doctor adjusts and grinds the opposing teeth based on experience. This method requires the dentist to have rich experience, and the doctor is adjusting During the grinding process, continuous inspection is required, and patients m...
