Filter by:The purpose of this study is to investigate the clinical efficacy of OsseoSpeed™ TX implants in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior maxilla up to 3 years after loading. Hypothesis: Early loading of the posterior maxilla is a safe and predictable procedure.
The purpose of this study is to investigate the clinical efficacy of OsseoSpeed™ TX 6 mm implants in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior mandible and maxilla up to 3 years after loading. The hypothesis is that one stage surgery using 6 mm OsseoSpeed™ TX implant in the posterior region is safe and predictable.
To investigate the clinical efficacy of OsseoSpeed™ TX implants in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior mandible up to 3 years after loading. Hypothesis: Early loading of the posterior mandible is a safe and predictable procedure.
BACKGROUND: The fabrication of complete dentures traditionally involves a series of complex technical procedures. Those procedures include two impressions for each jaw, the registration of the relationship between the upper teeth and the patient's head and usually two appointments for tooth try-in. However, recent studies have questioned the real need for such complex procedures. Simplified methods could have similar results if compared with conventional ones, and dentures would be delivered faster and with lower costs. OBJECTIVES: This study aims to compare the effectiveness complete dentures fabricated with a simplified or conventional method. METHODS: Eighty edentulous patients who requested treatment by maxillary and mandibular complete denture in a public dental clinic inside the University of Sao Paulo - Ribeirão Preto Dental School will be randomly divided into two groups. Group S will receive new dentures fabricated by a simplified method, whereas Group C will received new dentures according to a conventional method. Participants will complete a questionnaire for denture satisfaction and the oral health-related quality of life, 3 and 6 months after treatment. At the same time, a specialist in dental prostheses will evaluate the quality of new dentures.
The aim of the investigators study is to compare, in a prospective controlled clinical trial, the Locator® System with two other types of stress-breaking retention (Retentive Anchors and Magnets) for implant supported overdenture in atrophic edentulous mandible, with the use of Straumann Dental Implant System.
The study, with the ASTRA TECH Implant System, is comparing short implants (OsseoSpeed™) to standard length implants (OsseoSpeed™) in combination with bone grafting. The hypothesis is that the use of short implants in posterior maxilla with inadequate bone is as safe and predictable as placing standard length implants in combination with bone augmentation.
The purpose of this study is to find the difference between patient satisfaction, masticatory performance and cost between two occlusal schemes for complete denture prosthodontics.
Comparison of early and late loading of implants supporting full each prosthesis in upper jaw, using the Cresco prosthetic system on Straumann implants. The study hypothesis is that there is no difference between the bone loss (or gain) between the groups.
The purpose of this study is To demonstrate that there is no difference in change in bone level around P.004 implants between 1st stage surgery and 6 months post surgery when transmucosal implant placement is compared to submerged implant placement
The study is designed to evaluate the clinical and radiographic outcomes of Straumann® Bone Level Implant SLActive placed in healed alveolar ridge (at least 8 weeks post extraction) and immediately provisionalised versus the same type of implants placed in healed alveolar ridge but not provisionalised. In both cases the implants will be loaded at 16 weeks (final restorations). The outcomes will be evaluated over a 2-year period.
