Evaluation of Periodontal Health and Patient Satisfaction of CAD/CAM Fiber-Reinforced Composite Versus Porcelain Fused to Metal Extracoronal Attachment in Mandibular Distal Extension Removable Partial Dentures: A Randomized Clinical Trial
Abstract
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.
Conditions: Mandibular Distal-extension Prostheses.
Primary outcome: Evaluation of Bleeding index; Evaluation of Probing Pocket Depth (PPD); Evaluation Gingival Index (GI).
Enrollment: 12 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 12 participants or records.
