Study of Certain Prevail Implants Used to Treat All Types of Edentulism in the Maxilla and Mandible

Completed

Brief Summary: This observational, prospective clinical study evaluates the performance of the Certain Prevail implant system to show potential crestal bone and soft tissue preservation following the crestal bone. It will also evaluate implant performance.

Study (null) hypothesis: The preservation of crestal bone for the Certain Prevail implants will be the same as that for standard non-platform switched implants from contemporaneous studies (historical controls).

Detailed Description: This is a prospective, observational study of patients with partial or complete edentulism treated with the Certain Prevail dental implants. Restorations will consist of single tooth replacements, short and long fixed bridges, and overdentures and full dentures. All implants are placed using a single stage approach and temporalization occurring after two months of healing (early loading). Each center will strive to enroll a total of 20 patients.

Recruitment & Eligibility

Inclusion Criteria

patients of either sex and any race greater than 18 years of age
patients for whom a decision has already been made to use dental implants for treating an existing dental condition specifically:
1. dental implants restored as single tooth replacements, short and long fixed bridges, overdenture, or fixed full denture.
2. a temporary healing abutment will be placed on implant during implant placement surgery (single stage procedure).
patients must be physically able to tolerate conventional surgical and restorative procedures
patients must agree to be evaluated for each study visit, especially the yearly follow-up visit

Exclusion Criteria

patients with active infection or severe inflammation in the areas intended for implant placement
patients with a >10 cigarette per day smoking habit
patients with uncontrolled diabetes mellitus
patients with metabolic bone disease
patients who have had treatment with therapeutic radiation to the head within the past 12 months
patients in need of allogenic bone grafting at the site of the intended study implant for augmentation purposes. Grafting for treatment of dehiscence or fenestration must have occurred at least 8 weeks prior to implant placement surgery
patients who are pregnant at the screening visit
patients with evidence of severe para-functional habits such as bruxing or clenching
patients with less than 6 weeks of healing time post tooth extraction at the intended treatment site
