Factors affecting gingival response to pontics are the design, the material used and its roughness and the pressure exerted on the ridge. With a triangular ridge and a large available space, gingival health is promoted by ridge-lap pontics, (with large gingival and lingual embrasures) contacting the ridge with a glazed porcelain or a highly polished gold surface, and without pressure. With a rounded ridge and a narrow available space, modified-saddle pontics are used and the bucco-lingual width is reduced.
影响牙龈对桥体反应的因素包括设计、所用材料及其粗糙度以及施加在牙槽嵴上的压力。对于三角形牙槽嵴且有较大可用空间的情况，采用接触牙槽嵴的有釉质瓷或高度抛光金表面且无压力的牙槽嵴顶式桥体（有大的牙龈和舌侧间隙）可促进牙龈健康。对于圆形牙槽嵴且可用空间狭窄的情况，则使用改良鞍式桥体并减小颊舌向宽度。
