In medical surgery, bone drilling is an inevitable procedure. The thermal necrosis in the drilling process can affect post-operative recovery. In this study, the method of drill bit precooling is proposed in bone drilling with robot assisted system. The influence of process parameters on the drilling temperature were investigated and analyzed. The results showed that the method of drill bit precooling could reduce the drilling temperature. The drill bit starting temperature and the feed rate were more important parameters on the drilling temperature compared with rotational speed and cooling length of the drill bit. The quadratic regression model obtained from response surface experiments can predicted the drilling temperature correctly under the range of process parameters in this study. The optimal parameter combination is rotational speed = 1610 rpm, feed rate = 0.5 mm/s, the starting temperature of drill bit = 8°C, and the cooling length = 34.8 mm. The results provide an effective method to reduce thermal necrosis of bone cells in drilling.

“…Although using normal saline could reduce the drilling temperature, but the risk of infection was increased. 19,20 For lower temperature and clean operation zone, air cooling was used in the bone drilling process, but its efficiency was low. 21,22 Therefore, it is necessary to develop an effective method to reduce the drilling temperature.…”

“…Meanwhile, considering the similarity of biomechanical properties between bovine bones and teeth, the material adopted in this study was fresh bovine bone (age 3–4 years) of foreleg which was acquired from a butcher 3 h after the beef was butchered. 22 As shown in Figure 3, a new specimen processing method of experimental bovine bones was proposed and it can provide ideas for the variable control in experiments and for the replacement of resin canals that commonly used in dental researches. In order to guarantee reproducible results, the in vitro tests were repeated three times for each test condition.…”

Root canal preparation is a vital procedure during the treatment of pulposis and periapical periodontitis. However, the improper control of thrust force and torque in root canal preparation will cause nerve damage and cell necrosis. The aim of this study was to investigate and optimize the main factors influencing thrust force and torque and to establish an efficient predictive model for root canal preparation. This study was conducted on fresh bovine bones due to the similarity of structure and density with human teeth. A novel experimental platform was first built to measure the force and torque in canal preparation of different parameters. The effect of the experimental results on thrust force and torque was investigated based on Analysis of variance (ANOVA). The results indicated that the diameter of instrument, width of root canal, and feed rate are the most significant factors influencing the thrust forces and torque ( p < 0.05). Based on the above experiments, a Radial Basis Function Neural Network (RBFN) model was established to predict the thrust force and torque in a wider range of parameters. In confirmation tests, RBFN showed an excellent predictive model for prediction of thrust force and torque (error less than 14%) in canal preparation.
