“…In fact, previous studies have correlated RFA with height of the alveolar cortical bone. Also, recent bibliography in relation to implant failure evaluate peri-implantitis as the loss of vertical bone around an implant more than 4 mm during the first year, and 1.5 mm each following year (16)(17)(18). Design of prospective studies that acutely evaluate these parameters may provide important information about the ability to predict implant survival in relation to primary and secondary stability, influenced by bone density, height of alveolar cortical bone and bone-implant contact surface.…”

Background: Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. Patients and Methods: Seventy patients with complete mandibular edentulism underwent dental implant rehabilitation by means of the placement of 68 dental implants within the interforaminal region and subsequent placement of an overdenture. Primary implant stability was measured by means of RFA and it was expressed in terms of imPrimary implant stability was measured by means of RFA and it was expressed in terms of implant stability quotient (ISQ) on the day of the implant insertion and at the time of the healing abutment placement in a conventional implant two-stage surgical procedure. Results: Overall implant survival rate was 97.1% at the end of the follow-up period. The mean ISQ value for 3.75 and 4.25 mm diameter implants was 78.4 ± 5.46 and 80.83 ± 5.35 respectively, at the time of the implant placement; and 76.68 ± 4.34 and 78.22 ± 6.87 respectively, at the second surgical stage. No statistical differences were observed in relation to changes in mean ISQ value along the healing process. Conclusions: No statistical differences in terms of primary and secondary implant stability measured by RFA exists between 3.75 mm and 4.25 mm diameter implants in the conventional implant two-stage surgical procedure in patients with non-atrophied edentulous mandible being restored with an overdenture. Furthermore, no statistical association between RFA and the implant insertion torque was observed for endosseous dental implant placement at the first surgical stage.

“…4‐8 weeks of lag period is recommended clinically to allow for sufficient bone formation and to utilize accelerated osteoblast activity before reinsertion to replace an unstable miniscrew, and bone formation and enhanced regional osteoblastic activity were both confirmed during the initial 2‐6 weeks of healing in our beagle dog model. Histologically, however, the removal site was composed mainly of abundant woven bone rather than lamellated cortical bone even after 13 weeks.…”

Objective The aim of this study was to investigate the dynamics of alveolar bone formation and healing pattern after the removal of orthodontic temporary anchorage devices (TADs). Methods Miniscrews (N = 32) were inserted into the buccal inter‐radicular alveolar bone in beagle dogs. Afterward, miniscrews were removed at different time points during a 13‐week period and six different in vivo fluorescent markers were injected at 1, 2, 6, 8, 10, and 12 weeks. Serial changes in bone apposition at the removal and intact control sites were evaluated using μCT, histology, and bone histomorphometry. Results Gradual bone apposition at the TAD removal site was noted with bone volume/tissue volume (BV/TV) reaching the level of the control alveolar bone by 7 weeks. Histologically, newly formed woven bone was detected within the removal site which was distinct from the surrounding pre‐existing alveolar bone at 13 weeks. Accelerated mineral apposition rate (MAR) and bone formation rate (BFR) were noted between 2 and 6 weeks in the removal site (P < 0.05). Although MAR and BFR gradually decreased after its peak at 2‐4 weeks, BFR in the removal site was still higher than the control site at 10‐12 weeks (P < 0.05). Conclusions Spontaneous bone healing was noted after TAD removal with regional acceleration of MAR and BFR within 2‐6 weeks. However, the removal site was mainly filled with woven bone even after 13 weeks, suggesting a longer healing period is required for the quality of the alveolar bone to reach levels comparable to the surrounding alveolar bone.

“…Both the biomechanical and histological analysis of the healing bone suggested that early loading protocol produced more favorable osseointegration [13]. Furthermore, De Smet et al verified in a pig model that controlled loading can promote the maintenance of implant stability during the early critical healing period [14].…”

“…Although many studies were conducted to determine the outcomes of early loading applied to threaded implants [13–17], few experimental studies exist that investigate peri-implant bone reactions under early loading applied to plateaued implants. The cylinder plateaued implant has a series of separate circumferential fins existing along the intraosseous portion of the implant, and a large space between the fins which have previously been described for blood clot formation and woven bone development [18].…”

Objectives The purpose of this study was to evaluate the effect of early functional loading to plateaued implants on bone formation and implant stability in a dog model. Materials and methods Early loading (EL), nonloading control, and delayed loading (DL) groups were compared using six beagle dogs under functional loading. The Periotest® values were measured dynamically for 6 weeks. Peri-implant bone architecture was evaluated qualitatively by microcomputed tomography (μCT) and analyzed quantitatively by mineral apposition rates (MAR), bone-to-implant contact (BIC), and bone volumes (BV/TV) after the euthanasia at 3 and 6 weeks after loading. Results The EL implants showed poor stability at 1 week, but greater stability at 2 and 4 weeks after loading compared to DL implants. There was no significant difference between MAR of EL and unloaded implants at both time intervals. The EL implants displayed a significantly higher MAR when compared to DL implants at 3–5 weeks. A significantly higher BIC for the DL group was observed when compared to the EL group at 3 weeks following loading, however at 6 weeks; no significant difference between these groups was observed. The EL group gained a higher BIC than the no-treatment control group at 6 weeks. Conclusions For plateaued implant, the decreased healing time (1 week) displays a positive effect on peri-implant bone (re)modeling under functional loading during the early phase. Clinical relevance The early application of functional loading on plateaued implants can be used clinically to shorten the course of treatment and improve esthetics.
