Brief Summary
This investigation will be a clinical trial to study the performance of a high strength ceramic material for bridges to replace missing teeth. The ceramic material has been approved by the FDA for patient treatment. A computer technique will be used to make the bridges. The bridges will be cemented using an adhesive resin cement (MultiLink Automix/Ivoclar). The bridges are planned be evaluated for clinical performance at 6 months, 1 year, 2 years, 3 years, and if funding permits, 4 years, and 5 years. The purpose of the study is to measure how well the high strength bridges function over an extended period of time.

Outcome Measures
Primary Outcomes (1)
Bridge Failure
Bridge failure includes fracture of the bridge or loss of the bridge requiring placement of a new bridge at any time between delivery and five years.
from delivery of the bridge up to 5 years
Secondary Outcomes (3)
Bridge Loss of Retention
from delivery of the bridge up to 5 years
Number of Bridges Associate With Tooth Sensitivity
from delivery of the bridge up to 5 years
Number of Bridges Associated With Margin Staining
from delivery of the bridge up to 5 years
Study Arms (1)
Bridge
EXPERIMENTALThree unit high strength ceramic (lithium disilicate/emaxCAD by Ivoclar) bridges replacing a single tooth.
Interventions
Three unit high strength ceramic bridges replacing a single tooth.
Eligibility Criteria
You may qualify if:
- healthy periodontal status for the adjacent abutment teeth with 1:1 crown:root ratio
- abutment teeth must be asymptomatic prior to treatment
- Endodontically treated teeth will be acceptable for abutments as long as nonmetallic cores can be placed to retain the FPD since the lithium disilicate will be bonded to the abutments.
- no more than one bridge will be placed per patient. If a patient presents with more than one missing teeth acceptable for the study, premolar teeth will be included prior to anterior teeth. Each bridge will be three units and include only one missing tooth.
You may not qualify if:
- sensitive abutment teeth
- teeth with a history of direct or indirect pulp capping procedures
- patients with significant untreated dental disease to include periodontitis and caries
- pregnant or lactating women
- patients with allergies to any material in the study
- patients unable to return for recall appointments
