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.', 'detailedDescription': 'Twelve participants with bilateral maxillary Kennedy Class I, with the first premolars as the last standing abutments, will be recruited based on strict inclusion criteria from the oral and maxillofacial prosthodontic outpatient clinic. The canines and first premolars will be prepared to receive OT extracoronal attachments made from either CAD/CAM fiber-reinforced composite (Group I) or porcelain-fused-to-metal (Group II), according to group allocation. All participants will then receive a metallic removable partial denture. Periodontal health will be assessed through bleeding index, probing depth, and gingival recession at denture insertion and after six months. Patient satisfaction will also be evaluated at the six-month follow-up.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '20 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
