Condition: Alveolar Ridge Enlargement · Sponsor: University Ghent
After tooth extraction, shrinkage of the bone is expected with 50% reduction of alveolar width. Patients at least 3months after tooth extraction and in need of single oral implant placement in the anterior maxilla with both neighboring teeth present, were invited to participate in an inter-subject RCT if insufficient residual alveolar bone was left for proper implant placement. Guided bone regeneration has been used to recreate bone volume. A combination of xenogenous bone (Creos Xenogain , Nobel Biocare AB, Göteborg, Sweden) and autologous bone chips in a 1:1 ratio, is protected by a membrane fixated in the bone. A resorbable, non-stable membrane (Creos Xenoprotect, Nobel Biocare AB, Göteborg, Sweden) or non-resorbable titanium reinforced d-PTFE membrane (Creos Syntoprotect , Nobel Biocare AB, Göteborg, Sweden) can be used. This study aims to compare the effectivity of the two membranes by measuring changes in bone dimensions. The resorbable membrane has the advantage that it does not need to be removed, whereas the titanium reinforced membrane can protect the rebuilt volume better against external forces. Patients start to take systemic antibiotics (Amoxicilline 1g) and anti-inflammatory medication (ibuprofen 600 mg) 1h pre-operatively. Following local anesthesia (Septanest special, Septodont, Saint Maur des Fossés, France) and oral disinfection (Corsodyl mouth rinse, GSK, Wavre, Belgium), a large mucoperiosteal flap will be raised with two vertical releasing on each side…
