“…This device quantifies the implant-to-bone stability by analyzing the resonance frequency of a SmartPeg (Osstell) that is temporarily mounted to the implants and can be used at followup appointments to evaluate changes in implant stability over time. 15 Bone volume and quality were recorded according to the Lekholm and Zarb index, and the details are presented elsewhere. 6 ITVs for all implants were registered at surgery using the Osseocare motor and manual torque wrench (Nobel Biocare).…”

The purpose of this study was to evaluate patient satisfaction and clinical outcomes among subjects with mandibular overdentures supported by one or two immediately placed dental implants 5 years after loading. Materials and Methods: Thirty-six subjects (16 men and 20 women) received one or two dental implants in the anterior mandible, and all implants were loaded the day of surgery. Subjects were scheduled for follow-up 3-, 6-, and 12 months after implant placement and thereafter annually for 4 more years. Patient satisfaction scores were measured with the Oral Health Impact Profile-EDENT (OHIP-EDENT) questionnaire. Results: Seventeen subjects (7 male and 10 female) with a mean age of 59.4 years (range, 44 to 74 years) were available for the 5-year follow-up examination. Nine subjects with 10 failing implants were excluded during the first year and nine subjects were lost to follow-up. No implants failed between the 12-and 60-month follow-up examinations, and the need for denture maintenance was low. Mean peri-implant bone change was 0.92 mm, and the Spearman test failed to show correlation between the insertion torque value and implant stability quotient. Patient satisfaction scores increased significantly when compared with baseline values and continued to be high for both groups, with no significant differences. Conclusion: Ten implants in nine subjects failed early, but no failures were observed after the 12-month examination. No significant differences were found between subjects in the two groups with respect to implant survival rates and peri-implant bone loss, and patient satisfaction scores continued to be high. Although patient satisfaction and implant success were high during the 12-to 60-month period, the results should be interpreted with caution because of the high number of failing implants and patients lost to followup. More research is needed to study outcomes of treatment with immediately loaded mandibular implant overdentures.

Implant surface modification and implant design are the principle targets for achieving successful primary stability. The aim of this study was to measure implant stability quotient (ISQ) values of sandblasted, large-grit, acid-etched (SLA) implants with tapered straight body design during the healing period, and to determine the various factors affecting implant stability. Materials and Methods: To measure implant stability, resonance frequency analysis (RFA) was performed in 26 patients (13 women and 13 men) with 44 SLA implants with tapered straight body design. Implant stability (ISQ values) was evaluated at baseline and healing abutment connection (12 weeks), and the correlations between RFA and insertion torque (IT), bone quality, and jawbone were determined. Results: The mean ISQ value of the implants was 69.4 ± 10.2 at the time of implant placement (baseline) and 81.4 ± 6.9 at the time of healing abutment connection (P < 0.05). Significant differences were found between RFA and bone quality and between RFA and jawbone (P < 0.05). No significant differences were found between RFA and IT, insertion area, fixture diameter, and implant length (P > 0.05). Conclusion: ISQ values of SLA implants with tapered straight body design were high at baseline and healing abutment connection. It was concluded that SLA implants with tapered straight body design show improved primary and secondary stability, and that immediate or early loading may be applicable.

“…For this reason, primary stability is mainly related to the surgical site preparation (Turkyilmaz et al 2008), to host bone density (Turkyilmaz et al 2009;Marquezan et al 2012) and to implant geometry (O' Sullivan et al 2004;. Primary stability may evaluated by peak insertion torque (IT) value (Trisi et al 2009;Bayarchimeg et al 2013) and resonance frequency analysis (RFA; Meredith et al 1997;Heo et al 1998;Rasmusson et al 1999;Rowan et al 2015). The healing process, which follows implant placement, leads to new bone apposition onto the implant surface, thus providing the "secondary stability."…”

“…; Rowan et al. ). The healing process, which follows implant placement, leads to new bone apposition onto the implant surface, thus providing the “secondary stability.” When an implant reaches enough secondary stability, it should be ready to successfully support the final prosthetic restoration but there is a lack of knowledge about how much secondary stability is enough to safely support occlusal load.…”
