fa Comparison of soft tissue healing around implants in beagle dogs: flap surgery versus flapless surgery جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective</strong></p><p>  The objective of this study was to compare soft tissue healing after implant placement in flap and flapless surgery in the dog model. </p><p> <strong>Study Design</strong></p><p>  Mandibular premolars were extracted from 10 beagle dogs. The extraction sockets were allowed to heal for 8 weeks. After healing, 3 implants on each side of the mandible were implanted using either flap or flapless techniques. One implant was installed on each side at the 0-, 4-, and 6-week time point. Eight weeks later, the peri-implant soft tissue healing was subjected to clinical and immunohistochemical analysis. <strong></strong></p><p> <strong>Results</strong></p><p>  It was revealed that vascular endothelial growth factor (VEGF) expression, peri-implant crevicular fluid (PICF) volume, and the aspartate aminotransferase and alkaline phosphatase activity in PICF increased significantly in the 2-week flap group compared with the 2-week flapless group. Microvascular density and VEGF expression in the 8-week flap group was statistically significantly lower than the 8-week flapless group and normal group. Buccal gingival recession was less pronounced in the flapless group than in the flap group after 4 and 8 weeks. <strong></strong></p><p> <strong>Conclusions</strong></p><p>  Within the limits of this study, the results demonstrate that flapless surgery contributes to better esthetic outcomes in implants compared with the flap approach. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p><a href="http://www.oooojournal.net/article/S2212-4403(12)00154-X/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1550&slc_lang=fa&sid=1 Qun Lei 10031947532846007144 10031947532846007144 No School of Stomatology, Fujian Medical University, Fuzhou, China Jiang Chen 10031947532846007145 10031947532846007145 Yes Department of Oral Implantology, Affiliated Stomatological Hospital of Fujian Medical University, Fuzhou, China Jianhui Jiang 10031947532846007146 10031947532846007146 No Department of Oral Implantology, Affiliated Stomatological Hospital of Fujian Medical University, Fuzhou, China Xiaoming Fu 10031947532846007147 10031947532846007147 No Department of Oral Implantology, Affiliated Stomatological Hospital of Fujian Medical University, Fuzhou, China Hengzhang Lin 10031947532846007148 10031947532846007148 No Department of Stomatology, Affiliated Provincial Governmental Hospital of Fujian Health College, Fuzhou, China Chiyu Cai 10031947532846007149 10031947532846007149 No Department of Stomatology, Affiliated :union: Hospital of Fujian Medical University, Fuzhou, China
