Partial Denture Frameworks - An Introduction
Posted on 10/10/2011
While the removable partial cast framework has lost some of its popularity with the rise of implant retained prostheses, its durability, convenience and relatively inexpensive cost make it an important restorative option for patients. And although complex precision or semi-precision attachments may have seen their peak in terms of demand, the principles and applications of these attachments continues to apply - especially to implant dentistry. In addition, hybrid implant supported dentures, are rising in popularity and often incorporate a partial framework either cast or machined.
We will begin to discuss the cast partial framework in detail over the next several blogs. Our hope is that we may spur increased awareness and interest in their function.
Before we begin, I would like to define a couple of terms that will be used in these blogs:
Partial framework: The term "framework" will always refer to a cast metal framework - although technically there are now frameworks available in acetal resin or other non-metal materials.
Precision attachments: Precision attachments refer to machine made attachments purchased in their final metal state from the manufacturer. Lab modification may take place to adjust or alter the attachment, but the lab will not add to the attachment.
Semi-Precision: Semi-Precision attachments refer to castable or alterable plastic or metal attachments purchased from the manufacturer in an unfinished stage.
