Detailed Study Protocol Parameters |
Study Objectives |
Prospective, single-arm, postmarket surveillance descriptive study
|
Study Population |
Subjects with a need for implantation of either a TMJ Fossa- Eminence and Condylar Prosthesis System or a TMJ Fossa- Eminence Prosthesis System
|
Sample Size |
A first revision rate of 7% at 5 years was used for sample size estimation. For the precision of this estimate, the margin of error for the upper limit of the confidence band was set as 3.5%. If the assumed true proportion is 7%, the sample size required for a 95% 1-tailed error margin of 3.5% is 222 subjects. With allowance for 20% loss to follow-up, 278 subjects for the Total Joint System and 278 subjects for the Partial Joint System will be enrolled.
|
Key Study Endpoints |
Primary endpoint: Time to first revision, from which the revision rates will be derived for both the Partial Joint System and the Total Joint System at 1, 2, 3, 4, and 5 years. Secondary endpoint: • The impact of patient diagnosis on the timeframe to revision • Time interval (in months) after initial revision to subsequent revisions • Reasons for initial and subsequent revisions • Association between patient demographics and/or clinical data and device failure • Time to revision in which the Revision specifically entails revising the partial implant to a total implant
|
Follow-up Visits and Length of Follow-up |
Subjects will be recruited at participating study centers for inclusion in this study from the population of patients who present with severe TMJ disease that meets the criteria for partial or total joint reconstruction outlined in the approved indications for use. 5 years (60 months)
