研究组 & 干预措施
OT Vertical attachment
The attachment consists of a male part that is in the form of a steady with a central hole. This part is attached to the abutments .the female component is a white standard retentive clip engaging the outer walls of a steady male. It is incorporated in the partial denture together with a castable balancing pin that fits into the central hole of the steady male and aids in centering the prosthesis during the final stage of insertion; thereby ensuring a longer life to the retentive clips.
干预措施: OT Vertical attachment (Other)
OT Cap attachment
Beveled castable bar with micro-size sphere located in first molar region, and attached to the distal surface of the waxed crowns to be cast as one piece, Nylone caps of standard retention for micro size sphere this nylon caps fit onto their spheres and located in metal housing at fitting surface on the denture and Positioning rings to maintain the space for nylon cap during construction of the partial denture metal framework.
