NCT ID: NCT00906165 Completed - Clinical trials for Jaw, Edentulous, Partially

The Role of Immediate Provisional Restorations on Bone Level Implants

Start date: June 2008
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00901017 Completed - Clinical trials for Jaw, Edentulous, Partially

Comparison of Synthetic Bone Substitute and a Bovine-derived Xenograft in Horizontal Bone Augmentation

Start date: March 2006
Phase: N/A
Study type: Interventional

The objective of the study is to test the efficacy on bone formation of Straumann Bone Ceramic as a grafting material applied in buccal bone dehiscences on simultaneously placed oral implants.

NCT ID: NCT00900822 Completed - Alveolar Bone Loss Clinical Trials

Straumann Bone Ceramic Versus BioOss in Sinus Elevation

Start date: November 2005
Phase: N/A
Study type: Interventional

Straumann Bone Ceramic (SBC) and BioOss will be used as bone grafting materials when there is a need for bone augmentation in the posterior upper jaw. 9 months later the bone formation is evaluated. The patients are followed for 3 years.The study hypothesis is that the SBC is not worse than BioOss.

NCT ID: NCT00820235 Completed - Clinical trials for Jaw, Edentulous, Partially

Study Comparing Appearance and Function of Three Different Dental Implant Designs When Placed in Front Region of Upper Jaw

Start date: February 2009
Phase: N/A
Study type: Interventional

The primary objective is to compare the gum response to three different dental implant designs when placed in the front region of the upper jaw. The changes from baseline to one year after will be compared. The null-hypothesis is that the buccal soft tissue (gum) changes from baseline to one year after are equal for all three implant-abutment interface settings.

NCT ID: NCT00748241 Completed - Clinical trials for Jaw, Edentulous, Partially

Study to Evaluate Implant Survival Rate of Astra Tech Fixture ST in the Posterior Maxilla With One-stage Surgery and Early Loading

Start date: September 2000
Phase: N/A
Study type: Interventional

The purpose of this study is primarily to evaluate implant survival rate of Astra Tech Fixture ST placed in the posterior maxilla. A one-stage surgical protocol will be used and the implants will be loaded four weeks after implant installation (early loading). Marginal bone levels, plaque and status of the periimplant mucosa will also be evaluated. The subjects will be followed for three years.

NCT ID: NCT00746187 Completed - Clinical trials for Jaw, Edentulous, Partially

Study to Compare Marginal Bone Loss Around Implants From Two Dental Implant Systems.

Start date: December 2002
Phase: N/A
Study type: Interventional

The purpose of this study is to compare marginal bone level changes between ASTRA TECH Implant System; Fixture ST and Biomet 3i; Osseotite® Implants. Subjects with partial edentulism in the posterior maxilla and/or mandible will be included and a one-stage surgical protocol will be used. Implants will be loaded within 15 weeks from installation. The subjects will be followed for 3 years.

NCT ID: NCT00745121 Completed - Osteopenia Clinical Trials

Study Evaluating ASTRA TECH Implant System, OsseoSpeed™ Implants in the Upper Jaw in Women With Osteoporosis

Start date: July 16, 2008
Phase: N/A
Study type: Interventional

The overall objective of the study is to compare treatment with the ASTRA TECH Implant System, OsseoSpeed™ implant in the maxilla of postmenopausal women with and without systemic osteoporosis. The hypothesis is that there will be no difference in marginal bone level alterations between the two groups.

NCT ID: NCT00711425 Completed - Clinical trials for Jaw, Edentulous, Partially

Study on OsseoSpeed™ Implants in Patients Missing 2-5 Teeth in the Posterior Lower Jaw, Restored With Permanent Teeth Attached 6-7 Weeks Later

Start date: February 2004
Phase: N/A
Study type: Interventional

The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior mandible in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.

NCT ID: NCT00711282 Completed - Clinical trials for Jaw, Edentulous, Partially

Study of Bone Preservation When OsseoSpeed™ Implants Are Placed Immediately Following Tooth Extraction

Start date: December 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the clinical performance of implants placed in individuals who are about to loose one or more of their upper teeth. The main objective is to study how the surrounding bone tissue reacts to two different shapes of implants. Clinical performance, in wider terms, means esthetics and long lasting function. Half of the patients will receive a cylindrically shaped implant and the other half will receive a conical-cylindrical implant. The implants will be placed and after a healing period of 16 weeks the gum will be re-opened and the bone tissue response clinically evaluated. Permanent artificial tooth/teeth will be attached six weeks after that.

NCT ID: NCT00711113 Completed - Clinical trials for Jaw, Edentulous, Partially

Study on OsseoSpeed™ Implants Replacing 2-5 Teeth in the Posterior Upper Jaw, Restored With Provisional Teeth Attached 6-7 Weeks Later

Start date: December 2003
Phase: N/A
Study type: Interventional

The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior maxilla in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.
