Abstract

The rehabilitation of a completely edentulous arch opposing a dentate or implantsupported dentition presents significant biomechanical and prosthetic challenges. The rehabilitation of edentulous and partially edentulous patients requires a strategic approach to restore both function and esthetics. In cases where the maxillary arch is fully edentulous and the mandibular arch retains natural posterior teeth, a combination of a maxillary complete denture and a mandibular implantsupported prosthesis provides a balanced occlusal scheme. The presence of natural posterior teeth in the mandible influences occlusal load distribution, requiring careful prosthetic planning. This article presents a prosthodontic rehabilitation case involving a maxillary complete denture opposing a mandibular FP1 and FP2 implant-supported fixed prosthesis with five remaining natural posterior teeth. In cases of a single denture opposing an implant-supported fixed prosthesis, special attention must be given to occlusal harmony, implant-protected occlusion principles, and balanced denture stability to avoid rapid ridge resorption and prosthetic complications. This case emphasizes the importance of precise prosthetic planning, occlusal scheme customization, and regular follow-up to ensure longterm success and patient satisfaction. The report highlights the interplay between fixed and removable prosthodontics in a partially edentulous patient, providing a functional and aesthetic solution tailored to the patient’s needs.
