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. Twelve participants with bilateral mandibular Kennedy Class I, retaining only the first premolars as the last standing abutments, will be randomly assigned to two groups. Group I will receive OT extracoronal attachments made from CAD/CAM fiber-reinforced composite, while Group II 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.
