Abstract

Purpose: This study was carried out to evaluate stability of tapered and cylindrical implants in partially edentulous patients. Materials and Methods: The current study was done on 14 implants that were alienated randomly into two groups: Group I: treated with tapered implant, Group II: treated with cylindrical implant. Results: Clinical results: Modified Gingival Index (MGI) revealed a non-significant statistically difference on comparing results of 3 months and 6 months postoperatively (p=0.254 at 3 months, p=0.606 at 6 months). Modified Plaque Index (MPI) revealed a non-significant statistically difference on comparing results of 3 months and 6 months postoperatively (p=0.298). Probing Depth(PD) revealed a non- significant statistically difference on comparing results of 3 months and 6 months postoperatively (p=1 at 3 months, p=0.591 at 6 months). Stability: the mean value increased by time from baseline to after 6 months in Group I (61.57±6.4 to 71.57±6.08), however, the mean value increased from 63.14±7.17 to 74.57±5.53 in Group II. Implant stability revealed non- significant statistically differences for p-values (P 0.05). Radiographic results: Bone Density (BD):The statistical analysis between the two groups in the mean percent change in bone density revealed a non-significant statistically difference between the 6 months results. It was 1.88±1.37% for the first group and 11.54±15.63% for the second group (p=0.20).Conclusions: Conical and cylindrical implants have comparable biological effects during the healing process. The properties of the bone site can influence the stability of the implant.
