After deciding on having the extractions and the full plate, I decided on the "Premium" denture. You can see 3 different types of dentures. Economy, Good and Premium. It's pretty easy, if you want the longest lasting, then get the premium. Economy dentures often break after a couple years... I had to pay the full amount right then, before they would go any further. They want all the money in advance or they don't do the dentures. Be prepared to pay up front in full, before you go, or don't go.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
