The study subjects were healthy subjects, and the accuracy of the relationship between the upper and lower jaws obtained by different occlusal registration methods, as well as the clinical effects of different occlusal registration methods in the design and production of occlusal device
Conditions
Interventions
Experimental group:Artificial modification of the registration occlusal relationship in reverse engineering software
control group:The 3SHAPE oral scanning software automatically registers the occlusal relationship
