WHY MY DENTURES (DON'T) SUCK - PART 3

Part 3: Precision Denture Processing

Remember those dental material science classes?  In my day, Duane Taylor described polymerization shrinkage - its that pesky process by which our materials shrink dimensionally during their setting reactions.  This shrinkage impacts daily restorative procedures such as composite placement.  We have all developed techniques to allow for this by using some sort of layering techniques when filling teeth.
Polymerization shrinkage is particularly vexing during denture processing.  As dentures are processed, this shrinkage typically “draws” the intaglio away from the palate and additionally can pull teeth lingually.  This directly affects tissue adaptation and denture occlusion
 The amount of distortion varies depending on many factors: -  brand and quality of denture acrylic -
-  proper mixing of acrylic per manufacturer’s instructions -
- proper work flow including processing flasks, boil out tanks, etc -
- skill and experience of technician -

In a worst cas…
