Atraumatic preparation of the recipient site has been considered an important factor influencing implant survival. Heat generation during bone drilling has been reported to be related to various factors. The methodology for heat assessment and bone examination together with the osseous models are still points of great speculation. The present paper classifies and discusses some of those factors in detail from both biologic and clinical perspectives. The methods of heat assessment and bone examination are reviewed, and the advantages and the limitations of each technique are presented. Future considerations based on clinical data reported are suggested. Keywords: dental implant, heat generation, osseointegration, osseous models, thermocouple, thermography
