The conditions and design of the bridge body

The bridge body should have good self-cleaning effect, meet hygienic requirements, have sufficient strength, and have no adverse stimulation to the soft and hard tissues of the oral cavity.

The following aspects should be considered when designing a pontic: gingival surface, maxillofacial strength and external shape of the pontic.

In the maxillofacial area, consider reducing the buccolingual diameter, increasing the abduction gap, deepening the buccolingual groove or adding auxiliary grooves, and reducing the cusp inclination to reduce the pressure on the abutment, which is beneficial to the health of the periodontal tissue of the abutment.

The gingival surface can use the modified ridge bridge according to the actual situation of the patient.
