How to use it.

When the patient needs to make up the incisors, the dentist needs to obtain the patient's tooth model first, so that the technician can prepare the denture according to the model. When the two teeth in the patient's mouth are missing one, the dentist or the technician can make the denture preparation according to the model of the other incisor. However, when the patient has both upper incisors and the teeth are missing, the dentist or the technician cannot refer to the remaining left or right incisors to prepare the dentures. Therefore, in addition to the tooth model, the patient's tooth model must be obtained relative to the contour of the face. Benchmarks, dentists or technicians can create a tooth shape that is aligned with the contours of the face when preparing the denture.
