The modern resin-retained bridge retaining wing is usually sandblasted with an alumina powder. The metal wing needs to engage as much of the sound enamel. In the majority of cases the metal wing is taken to the incisal edge of anterior teeth and overlapping of the occlusal (biting) surface of the teeth for posterior teeth.
Management of congenitally absent teeth in one arch with crowding present in the other arch. Premature loss of permanent dentition from caries, trauma, iatrogenic damage or developmental abnormalities. The tooth of choice to replace a tooth missing in the anterior maxillary region is the maxillary second premolars.
For an ankylosed molar, distal teeth can respond to orthodontic force normally and thus can be used as substitute if the ankylosed tooth is extracted [citation needed]. Surgical luxation is sometimes used to break the ankylosis bridge to restore occlusion [citation needed]. For a case of PFE, the targeted molar can only be treated by osteotomy ...
The survival rate of bridgework can be affected by the span of bridge needed, the proposed position of the bridge, and the size, shape, number and condition of planned abutment teeth. [7] Furthermore, any active disease including caries or periodontal disease should be treated and followed by a period of maintenance to ensure patient compliance ...
The teeth used to support the bridge are called abutments. A bridge may also refer to a single-piece multiple-unit fixed partial denture (numerous single-unit crowns either cast or fused together). The part of the bridge which replaces a missing tooth and attaches to the abutments is known as a "pontic". For multiple missing teeth, some cases ...
