Stability of implants placed in fresh sockets versus healed alveolar sites: Early findings

摘要: Objectives The present study measured implant stability quotient (ISQ) values at three different time points after surgical procedures to compare whether the differed between implants placed in fresh extraction sockets versus healed alveolar sites. Materials and methods To measure stability, resonance frequency analysis (RFA) was performed 77 patients (53 women, 24 men) with a total of 120 dental implants. These were divided into two groups: Group 1 included 60 sites (22 maxilla, 38 mandible), 2 (41 19 mandible). Implant immediately placement (baseline), 90, 150 days later. Statistical made using multivariate regression linear model level (α = 0.05). Results Overall, means standard deviations ISQ 62.7 ± 7.14 (95% confidence interval [CI], 39–88) baseline, 70.0 ± 6.22 CI, 46–88) 90 days, 73.4 ± 5.84 58–88) 150 days. In 1, ISQs ranged 64.3 ± 6.20 75.0 ± 5.69, while 2, presented lower that 61.2 ± 8.09 71.9 ± 5.99 (P = 0.002). Anatomic location times periods only identified variables an influence on (P < 0.0001). Conclusions The stabilities exhibited similar evolutions thus osseointegration; however, superior all points.
