This may determine which type of design is most appropriate and therefore how many abutments are required. [24], Zirconia is used in anterior, and posterior fixed bridges, also on implants. The mold is taken using a rubber putty material. [4], Teeth with active disease such as caries or periodontal disease should not be used as abutments until the disease has been stabilised. [3], The bullet pontic is the second most favourable in terms of being able to maintain good oral hygiene, with the pontic only contacting one point of the alveolar ridge. Replacement of missing teeth with fixed bridgework may not always be indicated and both patient factors alongside restorative factors should be considered before deciding if providing fixed bridgework is appropriate. It is likely that increased span length will result in the abutments being subjected to increased torquing forces. Endodontically treated teeth have lost a large amount of tooth structure, weakening them and making them less able to tolerate additional occlusal loading. Aesthetics failures can also occur over a period of time including through wear of teeth, gingival recession or drifting of teeth. This index can be used to make a temporary prosthesis. The pontic is firmly attached to a retainer at one end of the span (major retainer) and attached via a movable joint at the other end (minor retainer).
