Brief Summary

The purpose of this study aimed to answer a clinical question whether In a patient with bilateral distal extension area, would the metal framework partial denture with OT vertical attachment versus partial denture with OT CAP attachment result in better patient satisfaction?

Conditions

Patient Satisfaction; Bone Changes

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

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.

Group Type: EXPERIMENTAL

OT Vertical attachment

Intervention Type: OTHER

new extra coronal castable attachment

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.
