NCT ID: NCT00723944 Completed - Partial Edentulism Clinical Trials

A Study of the Performance of Certain Prevail Implants Used in Short Fixed Cases

RadioCity
Start date: February 2005
Phase: N/A
Study type: Interventional

This prospective, randomized study evaluates the performance and crestal bone changes difference between the Osseotite Certain Prevail vs the non-lateralized design of the implant. Study (null) hypothesis: the crestal bone changes that take place after placement and loading of the Osseotite lateralized implants will be the same as for similar but non-lateralized Osseotite Certain implants.

NCT ID: NCT00713206 Completed - Partial Edentulism Clinical Trials

Prospective Study of NanoTite Implants Placed Into Fresh Sinus-Lift Augmentation Sites (VSSL)

Start date: September 2006
Phase: N/A
Study type: Interventional

This prospective, randomized-controlled, clinical study evaluates the ability of the NanoTite implant system to achieve integration and provide long-term support of a prosthesis when placed immediately in fresh sinus augmentation material. Control cases will be those where the sinus augmentation material is allowed four months of healing prior to NanoTite implant placement. In addition to implant performance, radiographic evidence of crestal bone regressive modeling will be used to evaluate differences between test and control cases. Study (null) hypothesis: The implants placed into sinus augmentation sites at the time of grafting will have the same integration success and maintenance of integration as for the implants placed after four months of graft healing.

NCT ID: NCT00001182 Completed - Healthy Clinical Trials

Evaluation of Patients With Unusual Diagnostic or Treatment Considerations

Start date: April 1982
Phase: N/A
Study type: Interventional

This study offers evaluation and treatment of patients with unusual diagnostic or treatment considerations. It is not designed to test new treatments; rather, patients will receive current standard of care treatments. The purposes of the study are: 1) to allow NIDCR staff an opportunity to maintain and improve their clinical skills; and 2) to evaluate referred patients for research potential. (Participants in this protocol will not be required to join a research study; the decision will be voluntary.) Patients in need of dental/oral diagnosis and therapy of interest to NIDCR staff dentists may be eligible for this protocol. Participants will have a comprehensive dental examination and may receive part or all of their treatment at the NIDCR clinic. Diagnostic procedures, materials and treatments used in this study are limited to those widely accepted in dentistry and are non-experimental in nature.
