Dental bridge between two teeth has a two-part shaft bonded together with end projections to fit with an adhesive bond into ground grooves at the facing surfaces of the existing teeth

摘要

The dental bridge structure between two natural teeth (6,7), to support an artificial tooth (3) in the gap (2) between them, is initially formed by grinding grooves (4,5) into the facing side surfaces of the teeth (6,7) with a cylindrical diamond grinder. The ends of the bridge shaft (1) have projections (13,14) which fit into the grooves (4,5) and be bonded in place with an adhesive. The shaft (1) is in two parts (17,18), each with an end projection (13,14), to be cut to length to fit the shaft (1) into the width of the gap (2) between the existing teeth (6,7). The flat surfaces (19,20) of the shaft parts are bonded together by an adhesive. The shaft (1) is covered by a cladding (22) of wound glass filaments for increased strength.
