Localized ridge augmentation in dogs: a pilot study using membranes and hydroxyapatite.

摘要: This study was designed to evaluate the potential reconstruct localized ridge defects with bone by preventing non-osteogenic extraskelatal connective tissue from participating in process of healing following experimental augmentation treatment procedures. Following elevation buccal muco-periosteal flaps, buccal, interproximal, and interradicular removed apical level second third premolar teeth were extracted create bucco-lingual that averaged 13 mm x 7 3.5 each quadrant two adult beagle dogs. The permitted heal for 90 days. did not fill new bone. Subsequently, flaps elevated a membrane placed over defect positioned so it rested on exposed adjacent defect. In quadrants test support materials used ensure space maintained between surface membrane. One as sham-operated control site, three sites received membranes no supporting implants membranes. surgical schedule yield sacrifice times 8 12 weeks. available covered membranes, and/or non-mineralized found all had been provided Histologic examination confirmed filled young, actively growing No formation (bone fill) observed site.
