Filter by:This prospective, multicenter study evaluates the performance of the Osseotite Prevail implant when to support a short fixed bridge with immediate occlusal loading, providing the patient with the use of a temporary prosthesis until the final prosthesis is made. Study (null) hypothesis: This is an observational study in which no concurrent control group will be observed. Results of the study will be compared with the performance of other Osseotite implants from published Osseotite multicenter studies.
This prospective, randomized study will evaluate the performance of the Osseotite Certain Prevail implant when compared to that of the non-lateralized version 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 a similar but non-lateralized Osseotite Certain implant.
This study will evaluate the contributions of the Nanotite implant design when used by graduate students in their first year of placing implants.
This prospective randomized study will evaluate the integration success while supporting a prosthesis for short implants placed into maxillary sites having minimal bone height that would otherwise need sinus augmentation. The resources utilized during treatment will be assessed. Study (null) hypothesis: the overall benefit of using short length implants to avoid sinus augmentation procedures will offset differences in the cumulative implant survival rates observed between treatment groups.
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.
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.
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.
