Brief Summary

This study is a clinical trial to determine the retention and durability of the anterior zirconia wing bridge. The type of zirconia-wing bridge the investigators are researching in this study has two wings which generally have three countersunk holes (meaning that the circumference of the outer portion of the hole is larger than the inner part of the hole). Composite resin (dental filling material) is placed in the holes as well as under and around the wings. Twelve patients will have bridges placed and be evaluated every 6 months (ideally) to determine if the bridge is staying in place (retention) and if it is resistant to fracture (durability).

Conditions

Missing Teeth; Partial-edentulism

Outcome Measures

Primary Outcomes (1)

• Number of participants with bridges still bonded to the teeth (retention)

  Determines how long the bridge stays bonded to the patient's teeth

  2 years observation

Secondary Outcomes (1)

• Number of participants with bridges that have no fractures (durability)

  2 years observation

Interventions

zirconia wing bridge OTHER

The zirconia wing bridge consists of an artificial tooth made out of zirconia and porcelain on the front side with two zirconia wings that are bonded (glued) onto the back of the two adjacent teeth in the patient's mouth.
