Osseointegration is an important factor in determining the success of a dental implant. It can be assessed from the osseointegration that occurs between the implant and the bone. The implant stability is determined by the osseous support at the implant-bone interface, which is commonly evaluated by histomorphometric analysis. This study aimed to evaluate whether the osseointegration level measured by a Low Resonance Frequency Analyzer (LRFA) gave results as good as those obtained by histomorphometric examination. Six male Macaca fascicularis were used in this study. In each animal, two types of loading were performed: immediate and delayed loading. Clinical examination and LRFA measurement were performed to determine osseointegration at the first and second weeks and at the first, second, third, and fourth months. After four months, histomorphometric examination was performed. The relationship between the histomorphometric examination and LRFA measurement was compared using the Pearson correlation coefficient. There was no significant difference in the osseointegration between immediate loading and delayed loading (p > 0.05) The bone-implant contact percentage in the first group did not differ significantly from that in the second group. Statistical analysis showed that there was a strong correlation between LRFA measurement and histomorphometric examination. Osseointegration could be evaluated through LRFA measurement as well as through histomorphometric examination.
