摘要: Abstract The Effect of Low-intensity Pulsed Ultrasound on Osteogenesis in Mini-pig Mandibles Yeong-Eun Yun, Jun Lee 1 , Seung-Ki Min Sang-Jung Kim Department Oral and Maxillofacial Surgery, Sun Dental Hospit al, School Dentistry, Wonkwang UniversityPurpose: objective this study was to examine the affected period amount bone formation during osteogenesis intramembranous using low-intensity pulsed ultrasound ( LPUS) vivo.Methods: Xeno-bone (Bio-oss) autogenous were grafted bilateral ly into mini-pig mandibles. left mandible served as control other treated with 3 MHz, 160 mW (output, 0.8 mW) stimulation for 7 days 15 minutes per day. mini-pigs sacrificed at 1, 2, 4, 8 weeks, micro computed tomography (μCT), a microscopic examination, statistical analysis performed specimens.Results: Based computerized image μCT scans, experimental group had an average 150% more new than that group. effect o f LPUS continued post operative 2 weeks. histomorphological examination showed similar resul ts.Conclusion: Our results suggest early intramembr anous vivo.Key words:Low-intensity ultrasound, vivo, Intramembranous bone,
