The effect of guided flapless implant procedure on heat generation from implant drilling / 대한치과보철학회지

PURPOSE: The aim of this study was to evaluate the heat generation in bone in vitro during the guided flapless drilling procedure and the effect of drilling methods on the heat generation. MATERIALS AND METHODS: A model that has missing the first and second mandibular molars bilaterally was used. In group A, classical flap implant surgery was performed. In group B, flapless implant surgery using surgical guide was performed. In group C, flapless implant surgery using surgical guide without up-and-down pumping motion was performed. Temperature was measured with k-type thermocouple and a real-time digital thermometer. The thermocouples were placed at 0.5 mm away from the osteotomy area at the depths of 3 mm and 6 mm. The measured values were evaluated with independent t-test. RESULTS: The mean temperature generated was 27.2degrees C (SD +/- 2.1degrees C) and 27.5degrees C (SD +/- 2.3degrees C) for groups A and B, respectively. These differences were not statistically significant. In group C, the mean temperature was 37.0degrees C (SD +/- 3.4degrees C). There were statistically significant differences between groups B and C with respect to the mean temperature. CONCLUSION: These findings suggest that guided flapless drilling with up-and-down pumping motion may not significantly increase the bone temperature.

A systematic implant treatment planning and concepts for clinical success / 대한치과보철학회지

STATEMENT OF PROBLEM: It is important to have a correct presurgical treatment plan before any implant surgery. It must contain substantial information about the patient concerned. However, the standard classification only notifies the dentist about various structural, pathological and physiological dimensions. Due to diverse structure of the jaw bone, current standard classification does not tell spatial dimensions of the available bone for implant insertion sites. PURPOSE OF STUDY: The purpose of this study is to report the establishment of the systematic implant treatment plan and its clinical treatment using Implan(R) program which is based on ASCIi-classification that is available for future diagnosis and scale of treatment and for systematic implant insertion. RESULTS: By assisting the systemic measurement of the available alveolus dimension during implant surgery, it was easy to set initial implant treatment plan. CONCLUSION: Using Implan(R) program which is based on ASCIi-classification system that allows the establishment of systemic implant treatment plan and successful clinical performance, it was possible to establish the founding of initial implant treatment plan, the acquisition of information, and the systematization of documentation.
