In this study, we performed basic research for the purpose of investigating whether intermittent PTH injection could acquire an osteogenic activity state for the case of bone augmentaion needed for dental implant treatment. Three beagles dogs mandibular fourth premolar and first molar in both sides were extracted and bone defect (5mm ×5mm ×15mm) after four weeks teeth extraction was made. Then after six weeks, the GBR treatment for the bone defect was performed using titanium mesh and screw fixation. Recombinant human Parathyroid hormone (PTH)，6μg/kg was prepared and subcutaneously injected in three times in a week 2 weeks before or 2 weeks after GBR treatment．We prepared two groups for this study. One is injected for two weeks before GBR treatment (before GBR) and the other is injected for two weeks after GBR treatment (after GBR). After three weeks GBR treatment，the mandible were removed and proceeded by the micro-CT analysis. The condition to analyze with micro-CT photography were; tube voltage 70.5kV, a tube electric current for this study. One is injected for two weeks before GBR treatment (before GBR) and the other is injected for two weeks after GBR treatment (after GBR). After three weeks GBR treatment，the mandible were removed and proceeded by the micro-CT analysis. The condition to analyze with micro-CT photography were; tube voltage 70.5kV, a tube electric current 114.5 μA, geometric amplifi cation 4.861 times, a condition of resolution 20.574μm/pixel. And the data were used to made mandibular BMD image with image analysis software (TRY/3D-BON BMD), and measured all organization quantity (TV), bone mass (BV), bone density (BMD), bone mineral density (BMC), BV/TV (%), bone surface area (BS) including the new formed bone at the bone defect area. Results; BV was 5.25mm3 for after GBR, 8.9mm3 for before GBR and 5.89mm3 for PS injection. BV/TV was 43.1% for after GBR, 41.0% for before GBR and 25.6% for PS injection. BMD was 494.5mg/cm3 for after GBR, 520.3mg/cm3 for before GBR and 465.2mg/cm3 for PS injection. BMC was 26.0mg after GBR, 46.3mg for before GBR and 27.4mg for PS injection. BS was 204 mm2 for after GBR, 262.3mm2 for before GBR and 303.7mm2 for PS injection. According to these findings, we concluded that osteogenic activity was able to acquire by intermittent PTH injection because the bone formation was enhauced at the GBR treatment area with the PTH injection compared to PS injection, and a mature bone was formed three weeks later of GBR treatment.
