Adjustment of Complete Dentures by the Functional Impression Technique

—The Reality of Dynamic Impressions—

Abstract

The primary goal of complete dentures is the functional restoration of lost esthetics, mastication and pronunciation.
Although the dentist is well aware of the necessity for taking an accurate impression, it seems that in reality he endeavors to fabricate complete dentures that are not sore, are stable, and chew well. Unlike crown and bridge impressions, complete denture impressions are more difficult since they demand functional considerations. We therefore arrive at the theory that we are making impressions, not taking them.
No matter how accurate the impression of the oral cavity, and how well it is recreated in the model, it is probably nothing more than just an outline. No matter how well the patient's outer appearance is restored, the impression is not good if the denture feels loose during mastication and when talking. That is to say, the dentist must be conscious of his intended goals when taking the impression.
The functional complete denture adjustment technique (dynamic impression) is not a particularly difficult or special technique. The impression, interocclusal registration, arrangement of the artificial teeth, and even the try-in of the wax denture are carried out by the operator's own methods. After that it is only necessary to fabricate a complete denture that in is harmony with and accommodates the body's masticatory system by using Hydro-Cast, which incorporates tissue treatment capacity, for a dynamic impression.
This is a report of my clinical knowledge gained from the functional complete denture adjustment technique applying the above methods.
