There are three basic fabrication methods for Implant-Supported Partial Prostheses: one-piece casting, framework cemented on prepared abutments, and laser welding. Which of these is preferred? A recent study 1, evaluated the vertical misfit of implant-supported frameworks made using these different techniques to obtain passive fit.
The study concluded:
The one-piece casted frameworks presented significantly higher vertical misfit values than those found for framework cemented on prepared abutments and laser welding techniques (P 1
What has been your experience with these different techniques and which one do you prefer?
