Bite control of total fixed prosthetics: a clinical case

Abstract

Using the example of a clinical case, demonstrate the suitability of an occlusal guide for the central relation (CR) control during fixed total prosthetics. For a patient complaining on the inconvenience and uneven occlusal contacts, a virtual patient’s digital “twin” was created in Avantis3D software (Russia) using intraoral dental scans and CBCT. 3D digital TMJ and occlusal analysis were performed, the position of the LJ was adjusted, and an occlusal template was designed and manufactured using 3D printing. The use of an occlusal guide made it possible to identify supracontacts that cause LJ displacement from the CR position. Selective grinding of existing supracontacts using an occlusal guide made it possible to return LJ to the CR position, provide multiple occlusal contacts, and eliminate existing complaints.
Conclusion.
The occlusal guide can be a reliable tool for CR control in conditions where other means of such a control are not available.
