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.
The object of this research is to test the effectiveness of Coenzyme Q10 (CoQ10) on symptoms of weakness, fatigue, and pain in persons with Charcot-Marie-Tooth disease (CMT).In this study we also intend to examine the impact of daily supplementation on overall quality of life.We are also interested in identifying any differences in serum ratios of CoQ10 in the oxidized and reduced forms.
This study will look at the impact of ascorbic acid (Vitamin C) on the progression of disease in people with CMT1A as compared to volunteers receiving a placebo. This study will assess whether is it futile to proceed with a larger, longer-term, placebo-controlled study.
Charcot-Marie-Tooth type IA (CMT1A) is the most prevalent hereditary peripheral neuropathy. Demyelination of peripheral nerves is the hallmark of CMT1A. Ascorbic acid has been shown to have a favorable influence on myelination in in vitro studies and in a mouse model for CMT1A. We will study the efficacy and safety of ascorbic acid treatment in young patients with CMT1A.
The purpose of the study is to determine whether equal subanesthetic doses of racemic ketamine is equally effective on females and males after surgical removal of third molars
