the purpose of this study was to conduct quantitative research on bone height and bone mineral density of palatal implant sites for implantation , and to provide reference sites for safe and stable palatal implants . three - dimensional reformatting images were reconstructed by cone beam computed tomography ( cbct ) in 34 patients , aged 18 to 35 years , using ez implant software . bone mineral density was measured at the 10 sites with the highest implantation rate , classified using k - mean cluster analysis based on bone height and bone mineral density . significant differences in bone height and bone mineral density were detected between these three clusters ( p<0.05 ) . the greatest bone height was obtained in cluster 2 , followed by cluster 1 and cluster 3 . the highest bone mineral density was found in cluster 3 , followed by cluster 1 and cluster 2 .
aimthe purpose of this study was to conduct quantitative research on bone height and bone mineral density of palatal implant sites for implantation , and to provide reference sites for safe and stable palatal implants.methodologythree-dimensional reformatting images were reconstructed by cone beam computed tomography ( cbct ) in 34 patients , aged 18 to 35 years , using ez implant software . 
 bone height was measured at 20 sites of interest on the palate . 
 bone mineral density was measured at the 10 sites with the highest implantation rate , classified using k - mean cluster analysis based on bone height and bone mineral density.resultsaccording to the cluster analysis , 10 sites were classified into three clusters . 
 significant differences in bone height and bone mineral density were detected between these three clusters ( p<0.05 ) . 
 the greatest bone height was obtained in cluster 2 , followed by cluster 1 and cluster 3 . 
 the highest bone mineral density was found in cluster 3 , followed by cluster 1 and cluster 2.conclusioncbct plays an important role in pre - surgical treatment planning . 
 cbct is helpful in identifying safe and stable implantation sites for palatal anchorage .
