About this trial

The aim of this randomized controlled trial is to evaluate the tridimensional bone stability after horizontal one-stage GBR using collagene membrane (OssMem) with a mix of Bovine Bone Substitute (A-Oss) and autogenous bone (test group) versus A-Oss and LCR-A, a synthetic bone (control group).

Eligibility criteria

Qualifiers

Patients that required an implant supported restoration and staged horizontal guided bone regeneration (defect of class IV according to Cawed and Howell) in both mandible or maxilla.

Patents able to understand and sign an informed consent.

Patients were to be 18 years or older with a residual horizontal ridge thickness of 4 mm or less (Cawood-Howell Class III- IV) in the intended implant site.

Smokers will be categorized into: 1) non smokers; 2) moderate smokers (smoking up to 10 cigarettes/day); 3) heavy smokers (smoking more than 11 cigarettes/day). Only categories 1 and 2 will be included.

Patients irradiated in the head and neck area.

Immunosuppressed or immunocompromised patients.

Patients treated or under treatment with intravenous amino-bisphosphonates.
