Abstract
The bone tissue destruction during drilling is still one of the crucial problems in implantology. In this study, the influence of drilling speed, coolant presence, and its temperature on bone tissue was tested using swine rib as a biological model of human jaws. The same method of drilling (with or without coolant) was used in all tested samples. The microscopic investigation estimated the size of the destruction zone and morphology of bone tissue surrounding the drilling canal. The achieved results were statistically elaborated. The study proved that the optimal drilling speed was ca. 1200 rpm, but the temperature of the used coolant had no significant influence on provoked bone destruction. Simultaneously, the drilling system without coolant compared to this with coolant has statistical importance on drilling results. Further in vivo studies will verify the obtained results.
Highlights
The first reports of implantology were recorded in ancient Egypt, where two teeth were connected by a gold wire passed through holes
Nine fresh swine ribs were obtained from the Polish Large White (PLW) swine breed
Our study showed that both speed and coolant used during drilling with constant force provoked significantly different changes in bone tissue
Summary
The first reports of implantology were recorded in ancient Egypt, where two teeth were connected by a gold wire passed through holes This discovery was made by the Egyptologist Hermann Junker in 1914, and it is still the best-known proof of advanced dentistry that thrived from those times [1]. Excessive destruction of the surrounding tissues like crushed bone, necrosis, or bone architecture annihilation influences the possibility of achieving good osteointegration, which is mandatory for dental implant success [4,5]. This bone change can vary according to the drill’s design, parameters, and cooling system utilized
