Guided Bone Regeneration, Platelet Rich Plasma and Low-Intensity Ultrasound Irradiation for Dental Implants

Abstract:

Because a concept of an osteointegrated dental implant system was established, prognosis of a dental implant at treatment improved and the treatment of restoration for missing teeth was changed. However, a dental implant treatment into atrophic jaw bone requires bone augmentation, obviously. At this time, we studied for the purpose of establishing the evidence of each method for clinical application of these bone augmentation method, such as guided bone regeneration (GBR), and autogenous bone block graft (BBG). In addition, we pursued the basic study of the evidence about the bone formation with platelet rich plasma (PRP) which recognized the availability in clinic. Furthermore, we present the results of basic studies which we tested for the purpose of applying a low-intensity pulse ultrasound (LIPU) irradiation applied to a fracture treatment in orthopedics area to intra-oral area, specially the condition after implant placement. In the results of comparison with GBR site and BBG, the differences of labeling bands were observed with a fluorescence microscopy. There was much labeling bands on GBR sections in comparison with BBG. This meaning that the bone remodeling around implants at GBR site was more active than BBG site. And the new bone formation by PRP was identified on soft X-ray graphically at first week after PRP applied mandible bone defect (experimental side). At same region of first week specimen, we confirmed positive reactions of platelet derived growth factor
