Study Notes

Denture rebase process involves separating the denture from the cast, cleaning the cast, preparing the denture by reducing the intaglio surface and lubricating certain areas
If the denture base is not suitable for relining, a rebase can be done instead which involves trimming back the acrylic denture base, fixing the block of teeth in place, and adding new base material
Rebasing process uses a denture flask to create a new base for the denture
Tissue conditioning is necessary before making new dentures or relining old ones to improve the health of the oral mucosa
Procedure involves having the patient close into centric relation, checking occlusion and vertical dimension, and applying tissue conditioner which is left in place for several hours
Tissue conditioners can be made of silicones for long-term use or plasticized acrylics for short-term use
Denture repair involves assembling fractured pieces with wax, trying them against a cast or opposing dentition, and making necessary adjustments to ensure correct fit
Common denture fractures include midline fractures of the maxillary denture and tooth fractures
When repairing a fractured complete denture, cause of the fracture must be determined and corrected, and the pieces assembled with wax against a cast or opposing dentition to ensure proper fit
Repair process may involve removing acrylic from the denture surface, adding new acrylic, and adjusting the occlusion.
