Background

One successful restoration is a co-operative crystallization of the physician and the oral technician, according to the patient's requirements and his own oral condition. How to perfectly embody the clinical requirements in the manufacture of the false teeth is a problem which needs to be solved urgently by doctors and oral technicians. Dental technicians are required to align denture dentitions on a wax jaw rest on a plaster model that is reproduced after an impression is taken in the patient's mouth in the making of removable or full dentures. However, the occlusion of the base plate and the wax jaw support prevents the dental technician from observing the alveolar ridge crest morphology of the missing dentition of the patient. The alveolar ridge crest morphology of missing dentition plays a crucial role in the tooth arrangement work of the dental technician. The alveolar ridge top morphology can guide the specific position of the alignment of the denture dentition and form the correct denture occlusal plane. Occlusion (occlusion), also known as occlusion, refers to the contact relationship between upper and lower dentition, while occlusion as a verb (occlusion) refers to the contact action or process between upper and lower dentition. In other words, the alveolar ridge crest morphology is closely related to the occlusal plane of the denture.
