Periodontal Health and Patient Satisfaction of CAD/CAM Fiber-Reinforced vs. PFM Attachments in Distal Extension RPDs
Sponsor: Ain Shams University
Summary
This randomized clinical trial aims to assess periodontal health and patient satisfaction in mandibular distal extension removable partial dentures using CAD/CAM fiber-reinforced composite versus porcelain-fused-to-metal extracoronal attachments. Twenty-four participants with bilateral mandibular Kennedy Class I, retaining only the canines and first premolars as the last standing abutments bilaterally, will be randomly assigned to two groups. Group I (n=12) will receive OT extracoronal attachments made from CAD/CAM fiber-reinforced composite, while Group II (n=12) will receive OT extracoronal attachments made from porcelain-fused-to-metal. All participants will then receive a metallic removable partial denture. The null hypothesis states that no significant differences will be observed in periodontal health and patient satisfaction between the two attachment types.

Mandibular removable partial denture retained on OT extracoronal attachment made from fiber-reinforced composite resin
Bilateral OT extracoronal attachments will be milled from fiber-reinforced composite resin after obtaining impressions of the prepared abutments. This will be followed by an overall impression of fabricating a Co-Cr removable partial denture to be retained in the attachments.
Mandibular removable partial denture retained on OT extracoronal attachment made from porcelain-fused to metal
Bilateral OT attachments manufactured from porcelain fused to metal by conventional technique after obtaining impressions of the prepared abutments. This will be followed by an overall impression of fabricating a Co-Cr removable partial denture to be retained in the attachments.
