Tomographic and Histologic Assessment on the Influence of the Use of a Collagen Membrane to Protect the Antrostomy After Maxillary Sinus Floor Augmentation.
Alveolar Bone Loss, Alveolar Bone Resorption
About this trial
This is an interventional treatment trial for Alveolar Bone Loss focused on measuring antrostomy, Maxillary sinus augmentation, collagen membrane, biomaterial
Eligibility Criteria
Inclusion Criteria:
- Presence of an edentulous atrophic zone in the posterior segment of the maxilla
- Height of the sinus floor ≤4 mm.
- Desiring a prosthetic restoration of the zone using a fix prosthesis supported by implants
- ≥ 21 years of age
- Good general health
- No contraindication for oral surgical procedures
- Not being pregnant.
Exclusion Criteria:The patients will be excluded if they present:
- A systemic disordered.
- Had a chemotherapic or radiotherapeutic treatment.
- Are smokers >10 cigarettes per day
- Have an acute or a chronic sinusitis.
- Had a previous bone augmentation procedures in the zone of interest.

Active Comparator
test site
control site
The space obtained underneath the sinus mucosa will be filled with the xenograft without protecting the antrostomy with a collagen membrane in the test sites. Bone to implant contact was measured at the turned and machined surface.
The space obtained underneath the sinus mucosa will be filled with the xenograft and a resorbable collagen membrane will be placed to cover the antrostomy only at the randomly selected control sites. Bone to implant contact was measured at the turned and machined surface.
