Predictable anterior determinants.
A method has been proposed to develop anterior determinants that are comfortable and pleasing to the patient, who participates in the development of their anterior esthetics and phonetics. This activity encourages final acceptance. Because the teeth are preoperatively restored to their final size and shape, a more conservative preparation results. The resultant provisional restorations provide guidelines for the final ceramometal restorations. The laboratory procedures are also simplified by detailed records and improved communication. The copings are finished to their proper dimension, and it becomes readily evident whether metal lingual surfaces should be provided. The porcelain can be applied in less time since the lingual concavity and incisal edge are "pre-formed." Usually fewer porcelain bakes are required due to uniform compensation for shrinkage. The incisolingual index creates a more positive and accurate form for the proposed restorations because it is mounted directly and securely to the articulator and not hand-positioned. The disadvantage of multiple, early appointments is far outweighed by the quality provided and the reduced time in adjustments. In final analysis this technique is less costly, ensures better esthetics and phonetics within less time, and creates better patient-dentist-technician relationships.
