Does anyone know a 98mm disk made of Bis-GMA for temporaries? Doctors are not liking relining traditional milled PMMA
I am guessing you are doing the shell technique? Why not just fill the acrylic temps with their normal composite and cure? Do they not make composite milling disks? My guess is that composite milling disks would chip like crazy.Does anyone know a 98mm disk made of Bis-GMA for temporaries? Doctors are not liking relining traditional milled PMMA
Their normal composite does not bond to PMMA and easily delaminatesI am guessing you are doing the shell technique? Why not just fill the acrylic temps with their normal composite and cure? Do they not make composite milling disks? My guess is that composite milling disks would chip like crazy.
Feedback I have received on acrylic relines:No idea, I am highly interested in what they disliked that this should solve.
They are temps... cut horizontal retention grooves on interior of temps.Their normal composite does not bond to PMMA and easily delaminates
MMA is methyl methacrylate? It says it is an experimental liquid? Been using it to do this since porcelain teeth went out of style.They need condition surface with MMA and then use a primer that will allow there light cured acrylic to bond to the successfully bond. I use this when I help in the all on four and these stay in function for up to 6 months.
Bonding of acrylic denture teeth to MMA/PMMA and light-curing denture base materials: the role of conditioning liquids - PubMed
The pre-treatment of denture teeth is critical regarding their bond-strength to denture base materials and in turn for the integrity of removable full and partial dentures. Light-curing denture base resins are more sensitive to the correct tooth pre-treatment compared to conventional MMA/PMMA...pubmed.ncbi.nlm.nih.gov
I read it as experimental to this purpose LCA(Light Cured Acrylics). I have done this forever on denture teeth but I also don't do many dentures. I started looking when I wanted to simplify the post operative adaptation of a milled appliance to newly placed implants without introducing tons of free monomer in the surgical site. With this, they can use any controllable LCA material that can be syringed in and cure quickly to pick up the position. More studies on this in PubMed.MMA is methyl methacrylate?
