• Effect of the length an implant is embedded in bone on mobility

抄録

‹Objective› The objective of this study was to investigate the relation between the length a dental implant was embedded in bone and its mobility in two different models, one with cortical anchorage and one without.<BR>‹Methods› Two dental implant models were made, one with cortical anchorage and one without. The implants were made of brass cylinders with a diameter of 4mm, which were embedded vertically 7, 9, 11, 13, 15 and 17mm into a resin model of bone (70 × 70 × 40mm) . The surfaces of the implants were treated by sand-blasting with glass beads (75pm) . The part of cortical bone was made of resin (Araldite^®) . The layer of cortical bone was 2mm in thickness. The part of cancellous bone was made of different resin (Rigolac^®) . Three models were made per each condition. The dental implant models were fixed under the same condition by using a vise. IM score was measured in a horizontal direction by means of IM checker. Parametric comparisons of IM score used two-factor analysis of variance. Significances of individual differences were evaluated by using the Tukey-Kramer test if ANOVA was significant.<BR>‹Results and discussion› About models without cortical anchorage, no significant difference was observed among data of 13, 15 and 17mm. About models with cortical anchorage, no significant difference was observed among data of 11, 13, 15 and 17mm. Additionally, IM scores of models with cortical anchorage were less than those without significantly (p<0.01) .<BR>‹Conclusions›<BR>1. The IM checker could quantify the mobility of dental implants which had various embedded lengths.<BR>2. Cortical bone was very important for implant stability.<BR>3. The embedded lengths which did not change IM score significantly were observed.
