Summary
Preserving the dimensions and contour of the alveolar ridge after the dental extraction, it´s of utmost importance to avoidsubsequent problems for the placement of a dental implant. The objective of this study was compare the dimensional changes through the analysis in Cone-beam computed tomography (CBCT), in pre and post sites preserved with the Bartee and Bio-Col technique with xenograft at 6 months of healing. In a 62-year-old patient, 6 alveolar preservations were performed in uniradicular dental organs, with a hopeless periodontal diagnosis, group A the Bartee alveolar ridge preservation technique (n = 3) and group B the Bio-Col alveolar ridge preservation technique (n = 3). Xenograft (InterOss ® Anorganic Cancellous Bone Graft Granules 0.25-1mm Sigma graft) was used in both groups. In the group A a bone graft was placed in the entire socket, assisted by a dense non-absorbable polytetrafluoroethylene membrane (Cytoplast ™ Regentex TXT-200 singles, Osteogenics Biomedical Inc, Lubbock, Texas). In the group B the bone graft was placed in 3⁄4 of the socket and the last 1⁄4 of the socket was occupied by an absorbable collagen dressing (CollaPlug ® Zimmer biomet). Measurements obtained by initial CBCT before recording alveolar ridge preservations were recorded, and the second CBCT was taken 6 months after healing obtaining the measurement vertically and horizontally, coinciding in the section plane. It was observed through dimensional analysis in group A and Group B, obtaining 13.58% and 20.76% of reabsorption vertically and 13.45% and 15.72% respectively at 6 months of healing, using xenograft, so there is no statistical difference significant in terms of dimensional changes between both techniques p> 0.05. Alveolar ridge preservation provides dimensional stability by counteracting the physiological resorption process, being a predictable option.
