ISA MAJLUF, M.; HARAN VEGA, J.  and  MORENO ZARATE, G.. Guided bone regeneration using aluminum oxide membrane in combination with osseointegrated implants. Rev Esp Cirug Oral y Maxilofac [online]. 2007, vol.29, n.4, pp.260-269. ISSN 2173-9161.

Alveolar bone loss has been a very important cause of complications in osseointegrated implant rehabilitation of edentulous patients. This paper evaluates the effectiveness of aluminum oxide membrane (Allumina) in the collapsed alveolar ridge where implants were used. Seven sites were studied in 5 patients. In each of these sites a HIS implant plus a non-biodegradable oxide aluminum membrane (Allumina^®), was placed for 14 weeks. All patients were treated with the same surgical protocol. The average gain (in mm) obtained in decreasing order was as follows: ANM: 1.7 mm, ANME: 1.6 mm, AND: 1.1mm, AV: 1.0mm, AP: 0.5mm. The clinical results were radiographically verified and these showed bone neoformation, in addition to favorable peri-implant bone density. The t-Student statistical analysis based on the clinical results was significant for all the parameters evaluated with the exception of AP.
