Straumann Holding AG (Straumann), a company focused in implant and restorative dentistry and oral tissue regeneration, is planning to complete the trial entitled “The Role of Immediate Provisional Restorations on Bone Level Implants. A Randomised, Single Blind Controlled Clinical Trial” for the product Straumann Bonelevel implant in December 2011. The objective of the study is to evaluate the clinical and radiographic outcomes of Straumann Bone Level Implant 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. The implants will be loaded at 16 weeks (final restorations), in both cases. The results will be evaluated over a 2-year period. The trial is being conducted in UK.

This randomized, single blind (investigator), active control, parallel assignment, efficacy study is currently recruiting approximately 24 participants. The principal investigator of the study is Nikos Donos, Prof. Dr. Eastman Dental Institute.

Straumann Bone level implant will be available in three diameters (3.3 mm, 4.1 mm, and 4.8 mm) and four lengths (8, 10, 12, and 14 mm) that will be suitable for all dental implant indications. There is a full matching prosthetic portfolio comprising 125 components, each of which is carefully designed for simplicity, reliability and esthetic performance. There is also a CAD or CAM custom abutment service in titanium and ceramic. With bone level designs the prosthetic connection is underneath the gum at, or close to, the crest of the jaw bone. The Straumann Bone Level Implant has been developed using a unique scientific concept called Bone Control Design to preserve bone and provide the foundation for long-term esthetic success. The implant have a cylindrical outer contour. The core is cylindrical in the apical region, becoming slightly conical in the coronal part of the implant leading to a mild taper. The implant features a thread to the top (identical thread as on Straumann Tapered Effect Implants) for extensive interlocking with the bone.
