Although periodontal factors do not usually have a direct effect on the survival of a fixed prosthesis, harmony between the prosthesis and the periodontium is critical otherwise esthetics, the longevity of the prosthesis and the periodontium will be compromised. A close interdisciplinary relationship between periodontics and prosthodontics is therefore necessary to avoid an unsatisfactory treatment outcome, requiring extensive and expensive retreatment. The design of the prosthesis, the number and quality of the abutment teeth, the preparation and the pontic, the occlusion and the material need to be considered when planning prosthodontic treatment. The location of the preparation margin and the contour and emergence profile of the prosthesis will influence the response of the gingival tissues to the prosthesis. Pontic design and cleansibility also contribute to the response of the gingival tissues as well as to the clinical and esthetic outcome. Even an optimal pontic design will not prevent inflammation of the mucosa adjacent to the pontic if pontic hygiene is not maintained by removal of plaque. Case selection and the patients' ability to carry out adequate oral hygiene are therefore essential for longevity of the prosthesis, and regular reviews provide an opportunity for early detection and treatment of failures.
虽然牙周因素通常不会直接影响固定修复体的存活率，但修复体与牙周组织之间的协调性至关重要，否则会影响美观、修复体的寿命以及牙周组织的健康。因此，牙周病学和修复学之间需要密切的跨学科合作，以避免治疗效果不理想，需要进行广泛且昂贵的再次治疗。在规划修复治疗时，需要考虑修复体的设计、基牙的数量和质量、预备体、桥体、咬合和材料。预备体边缘的位置、修复体的轮廓和外形以及表面处理都会影响牙龈组织对修复体的反应。桥体设计和清洁度也会影响牙龈组织的反应以及临床和美观效果。即使桥体设计完美，如果不能通过去除菌斑来保持桥体周围的卫生，也会导致桥体黏膜的炎症。因此，病例选择和患者进行充分口腔卫生的能力对于修复体的长期使用至关重要，定期复查为早期发现和治疗失败提供了机会。
