Abstract
For Longevity of implant, considerations of biomechanical and microbiological aspects must be done. Recently, due to the remarkable development of bone grafting procedure, Implant has been implanted into the more favorable sites but peri implantitis resulted from periodontal bacteria may obscure the long term prognosis. Although many different modalities have been introduced to treat the failed implant, Implants surface and irreversible bony destruction around the implant prevents good result. After Er,Cr:YSGG (waterlase) laser using the wave length of 2780nm has been introduced to dental field, good results have been reported. Because waterlase uses the hydrokinetic force of water, It is excellent device to detoxify the implant surface mechanically without the heat generation and damage to the implant surface. We designed to evaluate waterlase effect on the peri implantitis has been occurred after implantation. Four beagle dogs were involved. We have made four premolar extraction in each right and left side of the lower jaw and placed two implants in the anterior of the jaw as a control and six implant were placed posterior in each socket after extraction immediately as an experimental group. We tied floss silk in each implant to make peri implantitis intentionally. After three months, we explored peri implant sites on each experimental fixtures. Using waterlase laser irradiation was performed on that implantitis sites under 3W, air 30% and water 20% intensity for 2 minutes. In control group, we repositioned the flap to cover the exposed fixture without any supportive care. Three months later, we sacrificed experimental animals and extracted and preparated bone blocks with Donath and Breuner (1982), Donath (1988)’s methods and examined under microscope. We have obtained good reosseointegration around fixtures after treating with waterlaser irradiation. But it was shown fibroosseointegration in the control group.
