Long-term Study to Evaluate Different Dental Implant Alloys in Straumann 3.3mm Diameter Bone Level Implants

Institut Straumann AG49 enrolled

Overview

Patients with an edentulous mandible restored with implants who have participated in the core study CR 04/07 will be recruited for this extension study. No further interventions will be made for this extension study other than a clinical follow-up examination and questionnaires. Patients will not receive an investigational treatment in this study. Patients will be followed at 5 to 10 years from the date of the original implant loading

The primary study objective is to compare implant survival with the Titanium Zirconium (Roxolid™) implant compared the Titanium grade IV (SLActive®) implant between baseline (surgery) and 10 years. The following outcome parameters will be evaluated at 5 and 10 years post surgery for the two different implant types Straumann® Bone Level SLActive, diameter 3.3 mm, Titanium-Zirconium (Roxolid®) vs. Straumann® Bone Level SLActive implant, diameter 3.3 mm, Titanium Grade IV: * Implant survival * Implant success according to Buser et al. (1990) * Crestal bone level change measured by Orthopantomogram (OPT) * Soft tissue health * Clinical measurements * Prosthetic parts assessments: Success and maintenance * Oral Health Related Quality of Life (OHRQoL) * Product Safety (Adverse events and device deficiencies)

Outcomes

Primary Outcomes

Implant Survival

This is a long term follow up extension study including evaluations at 5 and 10 years after the implant procedure from the core study. Implant survival will be assessed based on surviving implants for all patients at 10 years.

Time frame: 10 years following implant procedure date

Secondary Outcomes

Crestal bone level change

The change in crestal bone level will be measured on standard x-rays taken at 5 and 10 years as per standard of care. An independent reviewer will evaluate all x-rays for the analysis.

Time frame: 5 and 10 years
