The primary stability of dental implants is fundamental for osseointegration. Therefore, this study aimed to assess the correlation between insertion torque (IT) and resonance frequency analysis (RFA) of implants placed in mandibles and maxillas of different bone densities. Eighty dental implants were placed in maxillas and mandibles, and IT and the implant stability quotient (ISQ) were measured at the time of implant insertion. Bone density was assessed subjectively by the Lekholm and Zarb index. The type I and II densities were grouped together (group A)as were the type III and IV densities (group B). The IT in group A was higher (Student t test, P = .0013) than in group B (46.27 ± 18.51 Ncm, 33.62 ± 14.74 Ncm, respectively). The implants placed in group A showed higher ISQ (Student t test, P = .0004) than those placed in group B (70.09 ± 7.50, 63.66 ± 8.00, respectively). A significant correlation between IT and the ISQ value was observed for group A (Pearson correlation test; r = 0.35; P = .0213) and for group B (r = 0.37; P = .0224). Within the limitations of this study, it was possible to conclude that there is a correlation between IT and RFA of implants placed in mandibles and maxillas of different bone densities.

ABSTRACT Objective The aim of this pilot study is to evaluate to value of primary implant stability for two-piece zirconia implants and longitudinally stability changes of implants during the healing period of 16 weeks. Materials and methods Ten patients treated with 12 two-piece non metallic zirconia dioxide root shape implant (4/10 mm, Axis Biodental, Les Bios, Switzerland) for single tooth replacement in the upper premolar area. Resonance frequency analysis (RFA) was used for assessment of longitudinally changes of implant stability during 16-weeks observing period. All patients have been re-evaluated 1 year after loading. Results Mean implant stability quotient (ISQ) value of initial implant stability for 12 implants was 60.25 (3.72). Statistically, significant decrease was noted in the first 3 weeks after insertion (p = 0.000). Also, statistically significant increasing of implant stability was recorded for observing period for 6th to 16th week. Conclusion Increasing of ISQ value during observing period suggests loading of two-piece zirconia dioxide root shape implant for single tooth replacement in the upper premolar area, after healing period of 4 months.
