For the first time during the visit, after the doctor carefully examined the mouth, the bite marks (initial impressions) were left.

The second time, based on the model taken out from the initial mold, individual trays are made to re-bite the teeth (fine mold). The mold must have clear and complete boundaries, appropriate length, accurate strap position, and strong adhesion.

For the third time, when visiting the doctor, it is necessary to determine the correct jaw position relationship for the patient and select the appropriate artificial teeth. Because all the internal teeth of patients with "edentulous jaws" are missing, the mandible is in a free state.

Therefore, under the guidance of a doctor, self-curing plastic bases or wax dips must be used as substitutes to help the patient regain the original position of the upper and lower jawbones (median dips relationship).

On this basis, select artificial teeth of appropriate color, size and shape, and arrange the front teeth in the patient's mouth. Try to make the patient satisfied with the midline of the teeth, the fullness of the lips and the height of the face.

The fourth visit was to try on a full denture. At this point, the denture was only in its infancy and was still a wax type. Wax was used to arrange the front and back teeth on the base. The base should meet the requirements of size, shape and thickness, and be placed in the patient's mouth for re-examination of the height of the lower one-third of the face, the occlusal relationship of the upper and lower teeth, the fullness of the face shape and the arrangement position of the teeth, etc.

If there are no abnormal conditions, it can be sent to the technician room. After going through processes such as boxing, filling, boiling and polishing, it is finally completed. Those with a short time of natural tooth loss, a full alveolar ridge, and a moderate thickness of the mucosal covering the surface can be considered for selection.

Patients who have had full dentures must be deeply impressed by the high number of visits. Indeed, the restoration of complete dentures is rather complex. From the first clinical visit to the final completion of the denture and its insertion into the patient's mouth, the patient usually needs to visit 4 to 5 times, as most of the work needs to be done inside the patient's mouth.
