Title: Temperature changes in the implant-bone interface during one-piece implants cutting – in vitro study

Abstract:

Purpose: The purpose of the study was to investigate the temperature changes in the bone directly adjacent to the implant site during the abutment portion of one-piece implant cutting. Material ad Method: Three different one-piece implants: Osteoplant, Nobel Direct, Q-implant, were cut with air-turbine burs after implantation in fresh pig ribs. During cutting, air and air-liquid coolants were used. The temperature changes were evaluated using thermocouple type K. Results: It was found that regardless of the cutting technique, the temperature of the bone always increased during the cutting procedure. The critical temperature threshold T=10C (47C) was always exceeded, when only the air coolant was used, although when the air-water spray coolant was utilized during the cutting procedure, it prevented the temperature to exceed this critical level. Conclusion: Temperature generated during cutting abutment parts of an implant, is transferred to the bone. The extent of thermal changes in the bone depends on the cutting technique. Constant air-water cooling during the cutting procedure is a recommended technique in order to avoid overheating the implant-bone interface. The dry cutting technique, using only an air coolant, should be avoided as it can induce sufficiently high thermal damage in the bone adjacent to the implant, which leads to compromise of the osteointegration process.
