성견에서 하악골 수평골신장술 후 임플란트 지연 식립시 조직형태계측학적 평가

Abstract

Purpose : This study was aimed to evaluate osseointegration at implantation after consolidation in the distracted narrow alveolar bone. Materials and Methods : Three adult mongrel dogs, weighting about 9-10kg, were used in this study. The lower premolars were extracted and horizontal distraction was performed using distraction device after 8 weeks. 8 weeks after distraction, screw-type implants is installed. The dogs are sacrificed after 4 weeks. Results : Direct bone contact is achieved and there were no significant difference between control group and experimental group at implantation area after 4 weeks. Conclusion : Implantation after horizontal distraction in narrow alveolar ridge is useful technique.
