“…Radiographic examination is an important clinical tool because it is non-invasive and can be easily performed. Taba et al 19 showed a radiographic method based on greylevel analysis using image software to assess the bone density, with results similar to the histopathology. Bone composition can be assessed by Dual X-ray Absorptiometry (DXA), which provides a quantitative measurement of the mineral phase.…”

“…Implant TS lll SA 3.5 × 10 mm (Osstem, Seoul, South Korea) was used, and its size was selected based on mongrel bone width and nerve location. [16] Miniscrews (1.4 × 6 mm, Jeil Medical Co., Seoul, South Korea) were placed 5 mm away from the distal implant as a reference point. Osseointegration of all implants were con rmed using x-ray and resonance frequency analyzer (Ostell Mentor, Ostell, Gothenburg, Sweden) and ISQ values of all implants were over 70.…”

Background Osseointegrated implants are considered as clinically non-movable. Parathyroid hormone (PTH) is known to play a significant role in the regulation of bone remodeling and in intermittent, low doses, result in osteoanabolic effects. This study aimed to investigate the effects of PTH and corticotomy, both under traction force, on osseointegrated implants. Methods Four implants—two in each hemimandible—were placed in each of the three study mongrels. Each mongrels were designated as control, normal dose PTH (PTH-1), and high dose PTH (PTH-2) groups, with each groups further subdivided into non-surgery and surgery groups. After osseointegration, mechanical force with NiTi closed coil springs (500g) was applied around each implants. Corticotomy was performed around one of four implants in each mongrels. Parathyroid hormone was administered locally on a weekly basis for 20 weeks. Clinical movement of the implants were evaluated with the superimposed 3D- scanned data, bone- microarchitectural and histologic examinations Results Superimposition analysis showed continuous movement of the implants in PTH-1 group. Movement was further justified with lowest bone implant contact (adjusted BIC; 44.77%) in histomorphometric analysis. Upregulation of bone remodeling around the implant was observed in the normal dose PTH group. In the surgery subgroups, the remarkably higher adjusted BIC compared to the non-surgery subgroups indicated increased bone formation around the implant surface. Conclusion The results indicate that the balance of osseointegrated implants in bone remodeling can be shifted via various interventions. Clinical Relevance Upregulated bone remodeling by PTH and corticotomy under continuous mechanical force showed the possible implications on the clinical implant movement.

In the surgery implants, the remarkably higher adjusted BIC compared to the non-surgery implants indicated increased bone formation around the implant surface. ConclusionThe results indicate that the catabolic and anabolic balance of osseointegrated implants in terms of bone remodeling can be shifted via various interventions including pharmacological, surgical and mechanical force.Clinical RelevanceUpregulated bone remodeling by PTH and corticotomy under continuous mechanical force showed the possible implications for the movement of osseointegrated dental implant.
