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 an adjusting guide making method. The method comprises following steps: an upper jaw 3D model and a lower jaw 3D model of a patient are obtained with a 3D scanning technology,and a 3D position relation of upper jaw dentition and lower jaw dentition of the patient in different states is obtained; an occlusion contact relation of the patient in different states is obtainedon the basis of the 3D position relation; lower jaw positions of the patient in different states are gathered in 3D software, a repair form of upper jaw anterior teeth is designed based on this, and adiagnostic model is formed; an ideal repair effect of the upper anterior teeth of the patient and a position relation of the upper anterior teeth and the lower jaw dentition in different states are obtained through 3D design on the basis of the 3D model; occlusal interference is avoided by adjusting incisal form of lower jaw anterior teeth, and an adjusting guide is designed by the 3D software onthe basis of the adjusted incisal form of lower jaw anterior teeth; and the diagnostic model and the adjusting guide are obtained through 3D printing. The adjusting guide made with the method can rapidly and accurately adjust and grind dental 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...
