THERMAL CHANGES OBSERVED AT DRILLING SITE DURING BONE DRILLING Model study in bovine rib

Temperature change in pig rib bone during implant site preparation by low-speed drilling

OBJECTIVES The purpose of this study was to evaluate the temperature change during low-speed drilling using infrared thermography. MATERIAL AND METHODS Pig ribs were used to provide cortical bone of a similar quality to human mandible. Heat production by three implant drill systems (two conventional drilling systems and one low-speed drilling system) was evaluated by measuring the bone temper...

Informative title: Thermal Osteonecrosis and Bone Drilling Parameters Revisited Concise title: Thermal Osteonecrosis and Bone Drilling

An experimental investigation on thermal exposure during bone drilling.

This study presents an experimental investigation of the effects of spindle speed, feed rate, and depth of drilling on the temperature distribution during drilling of the cortical section of the bovine femur. In an effort to reduce measurement uncertainties, a new approach for temperature measurements during bone drilling is presented in this study. The new approach is based on a setup for prec...

Temperature effects in the drilling of human and bovine bone

Bone is an anistropic material, the drilling of which is an essential part of internal ®xation in orthopaedic and trauma surgery. Some research has been carried out into the drilling of bone, but there are no de®nitive recommendations available on the most suitable drill shape or on the optimum drilling speed that should be used in surgical practice. The heat generated during the drilling of bo...

Towards defining dental drilling competence, part 2: a study of cues and factors in bone drilling.

The study of expertise in surgery aims to facilitate the development of improved training methods by understanding the characteristics of expert practitioners. In this article and its companion, we present our study of the characteristics of competence and expertise in the field of oral surgery. We observed participants of different skill levels as they performed an ex vivo drilling task design...
