Abstract This study was carried out to evaluate the effect of LLLT on implant osseointegration by evaluating implant stability as well as marginal bone height in controlled diabetic patients. Ten patients were selected from among those attending the out-patient clinic, Prosthodontic Department, Faculty of Dentistry, Ain Shams University to participate in this study. Patients were precisely selected and thoroughly examined in an attempt to reduce human variables and eliminate any factor that might adversely affect the results of this study. Patients were rehabilitated by maxillary complete denture and mandibular implant overdenture. Standard clinical and laboratory techniques were followed in denture construction for all patients. Patients participating in this study were randomly divided into two equal groups. group A: implants of patients in this group were not exposed to LLLT (control group). group B: Implants of patients in this group received LLLT at a predetermined exposure protocol (study group). Surgical installation of the implant was performed under strict aseptic conditions and immediate loading protocol was followed. Patients were recalled frequently for post-insertion inspection and adjustments as well as for LLLT therapy in group B. Follow-up visits were scheduled at the time of denture insertion, six and twelve months after implant installation for inspection of the prosthesis, implant stability evaluation via periotest® and radiographic evaluation of the peri-implant marginal bone height changes evaluation by CBCT. Results obtained from this study showed:Implant stability evaluation : o Study group recorded significantly better overall PTVs compared to control group. o Study group recorded significant PTVs compared to control group at loading only, however no difference in PTVs was observed between groups after 6 and 12 months. Marginal bone height: o Marginal bone height was significantly lower at 12 months than at 6 months in both groups. o Control group recorded significantly higher mean marginal bone height than study group. |
