Abstract
The relationship of the maxilla and mandible is defined by the two parameters of horizontal and vertical relation. Although it is in general adequate to only consider the horizontal relationship when there are vertical stops on teeth, for the edentulous patient, who has no teeth, it is necessary to consider verticentirc, which is a mix of horizontal and vertical relationships. During conventional fabrication of full dentures, this has often been decided “in one shot” at what was called occlusal registration. This is because conventional fabrication methods for full dentures are linear techniques. However, when there is a problem with the maxillomandibular relationship of the existing dentures, prostheses fabricated in this way will often not feel comfortable and will require considerable adjustment time. Furthermore, remounting may be necessary for such reasons as problems arising in the joint.
The goal of the tentative denture method is to solve all of these problems beforehand and then to proceed with fabrication of the new denture. The tentative denture method is a technique that is a type of treatment denture that uses the existing prosthesis to determine the essential conditions for the new denture before the final impression. These conditions include modifications of the mucosa, determination of the form of the margins, and measurement of the maxillomandibular relationship.
I will explain how to determine verticentrrc using the tentative denture method.
