Partial denture service may be logically divided into six phases. The first phase is related to patient education. The second phase includes diagnosis, treatment planning, design of the partial denture framework, treatment sequencing, and execution of mouth preparations. The third phase is the provision of adequate support for the distal extension denture base. The fourth phase is establishment and verification of harmonious occlusal relationships and tooth relationships with opposing and remaining natural teeth. The fifth phase involves initial placement procedures, including adjustments to the contours and bearing surfaces of denture bases, adjustments to ensure occlusal harmony, and a review of instructions given the patient to optimally maintain oral structures and provided restorations. The sixth and final phase of partial denture service consists of follow-up services by the dentist through recall appointments for periodic evaluation of the responses of oral tissue to restorations and of the acceptance of restorations by the patient. The following is an overview of these phases.
