[QUOTE="Kreyer, post: 6436, member: 602"] Here is a summary of published literature on this subject. The basic result from testing at UCSF is remove the glaze before processing and wet the acrylic resing tooth with monomer before processsing. As John and Brian stated there are many variables to take into consideration such as clean boil-out, separating solution and processing techniques. The complete article can be read in JPD or online at [url=http://journals.elsevierhealth.com/periodicals/ympr/search/quick]Elsevier[/url] Failure load of acrylic resin denture teeth bonded to high impact acrylic resins☆☆☆★★★ Donna Barpal, DDSa, Donald A.
