The bridge body should have good self-cleaning effect, meet hygiene requirements, have sufficient strength, and have no adverse stimulation of oral soft and hard tissues.
The design of the bridge body should be considered from the following aspects: the gingival surface of the bridge body, the strength of the maxillofacial surface and the external morphology.
Maxillofacial can consider reducing buccal tongue diameter, increasing abduction space, deepening buccal tongue groove or adding parasulcus, reducing the inclination of the tooth tip to reduce the pressure on the abutment, which is conducive to the periodontal tissue health of the abutment.
The gingival surface can be modified with a lid ridge bridge according to the actual situation of the patient.
