RESUMEN

This article describes how to use CBCT and an intraoral scanner in a fully edentulous case that enables the clinician to place implants with flapless guided surgery and to engage prefabricated, customized implant abutments at the time of implant surgery, with only 1 clinical consultation before implant surgery. The patient's existing denture is used to simulate the teeth, the soft tissue and the vertical dimension of occlusion, and jaw relationship in the fully edentulous jaw. It provides clinicians with a fast workflow and improves clinical efficiency.

RESUMEN

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.
