PURPOSE. The aim of this study was to investigate a comparison of implant bone bed preparation with Er,Cr:YSGG laser and conventional drills on the relationship between implant stability quotient (ISQ) values and implant insertion variables. MATERIALS AND METHODS. Forty implants were inserted into two different types of pig rib bone. One group was prepared with conventional drills and a total of 20 implants were inserted into type I and type II bone. The other group was prepared with a Er,Cr:YSGG laser and a total of 20 implants were inserted into type I and type II bone. ISO, maximum insertion torque, angular momentum, and insertion torque energy values were measured. RESULTS. The mean values for variables were significantly higher in type I bone than in type II bone (P<.01). In type I bone, the ISO values in the drill group were significantly higher than in the laser group (P<.05). In type II bone, the ISO values in the laser group were significantly higher than in the drill group (P<.01). In both type land type II bone, the maximum insertion torque, total energy, and total angular momentum values between the drill and laser groups did not differ significantly (P>.05). The ISO values were correlated with maximum insertion torque (P<.01, r=.731), total energy (P<.01, r=.696), and angular momentum (P<.01, r=.696). CONCLUSION. Within the limitations of this study, the effects of bone bed preparation with Er,Cr:YSGG laser on the relationship between implant stability quotient (ISO) values and implant insertion variables were comparable to those of drilling.
