When this surgical technique was established initially, membranes made of expanded polytetrafluor- oethylene (ePTFE) were used. Although clinical and experi- mental studies found excellent treatment results using ePTFE membranes, wound healing com- plications with infection sequelae arose following the exposure of membranes. Therefore, clinicians and researchers have advocated the use of bioabsorbable barrier membranes (Zellin et al. 1995). There are two main ma- terials used to manufacture bioabsorbable membranes: colla- genderivedfromananimalsource and synthetic materials. The ability of collagen to promote pro- genitor cell adhesion, chemotaxis, homeostasis and physiological degradation, along with its ease of manipulation and low immuno- genicity, make it an ideal barrier material (Rothamel et al. 2004). Successful regeneration is possible, provided that cell ex- clusion and space maintenance prevails for the time needed for repopulation of the site with pro- genitor cells. This period may vary between three to 12 months for bone regeneration in edentu- lous areas. The structural integ- rity of implanted bioabsorbable barrier membranes needs to be preserved for an adequate period to allow maturation of the newly formed tissue under the mem- brane-protected space. The purpose of the present case report is to evaluate clinically and histologically a ridge preser- vation using a xenograft and re- sorbable collagen membrane fol- lowing tooth extraction. Case study A 40-year-old female patient was selected for this case report. Other than localised periodontal disease around a right temporary man- dibular second molar, she had no systemic disease. The patient was referred for extraction of this molar. The reason for the extrac- tion was type III mobility and the radiological image. Surgical treatment Following administration of local anaesthesia (4 per cent articaine and 0.001per cent epinephrine), the tooth was elevated and an atraumatic extraction was per- formed. A full-thickness muco- periosteal flap was elevated to expose both the labial and the lin- gual aspects of the alveolar ridge. The extraction socket was then curetted to remove all the soft tis- sue. A combined two- and three- walled bony defect of 6 and 5mm and a fenestration of the buccal plate were observed (Figs 3 & 4). A ridge preservation technique was performed using a xenograft material (a blend of granules of page 19DTß Fig 3 Fig 4 Fig 5 Fig 6 Figs 3 & 4_Image of the combined two- and three-walled bony defect of 6 mm and 5 mm, and the fenestration of the buccal plate Figs 5 & 6_A ridge preservation technique was performed using a xenograft material and a double layer of resorbable collagen membrane
