“…14,21 Many studies have found that the use of irrigation at drilling speeds commonly recommended by manufacturers of implants is an efficient way to keep the temperature of the bone below the threshold that would lead to osteonecrosis. [22][23][24] The results of the present study have histometrically confirmed that even with lower drilling speeds there were no differences between the drilling techniques in BIC and BAFO. From a histomorphological perspective too we found no signs of osteoclastic activity, necrosis, or inflammation.…”

“…At the same time, several implant drills are already commercially available for the same reason. Ceramic composite drills containing zirconium oxide were able to maintain their drilling ability and maintain lower temperatures than stainless steel drills during cavity preparation in an in vitro study 5. More recently, zirconia has also been used as a fixture material because of its biocompatibility and physical properties.…”

PurposeZirconia is a good candidate material in the dental field. In this study, we evaluated biological responses against a zirconia drill using a bone cavity healing model.Materials and MethodsZirconia drills, stainless steel drills, and the drilled bone surface were observed by scanning electron microscopy (SEM), before and after cavity preparation. For the bone cavity healing model, the upper first and second molars of Wistar rats were extracted. After 4 weeks, cavities were prepared with zirconia drills on the left side. As a control, a stainless steel drill was used on the right side. At 3, 7, and 14 days after surgery, micro‐CT images were taken. Samples were prepared for histological staining.ResultsSEM images revealed that zirconia drills maintained sharpness even after 30 drilling procedures. The bone surface was smoother with the zirconia drill. Micro‐CT images showed faster and earlier bone healing in the zirconia drill cavity. On H‐E staining, at 7 days, the zirconia drill defect had a smaller blank lacunae area. At 14 days, the zirconia drill defect was filled with newly formed bone.ConclusionsThe zirconia drill induces less damage during cavity preparation and is advantageous for bone healing. (197 words)

Abstract:The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to measure temperature in bone hole. Results showed that the drill shape could influence drilling temperature greatly. The maximum drilling temperature of diamond spherical grinding head is 46.31°C. The maximum drilling temperature of common twist drill is 42.1°C and that of diamond bullet-like grinding head is 38.29°C. The drilling temperatures at drill speed is under 560 r/min, 900 r/min, 1,250 r/min and 2,100 r/min are 38.84°C, 41.1°C, 43.84°C and 46.31°C. This reflects that under same of other drilling parameters, drilling temperature increases with the increase of drill speed. The maximum bone drilling temperatures of diamond punch pin under 2,100 r/min speed of mainshaft and air cooling conditions vary as feed speed increase firstly and then decrease. The normal saline spray cooling has the lowest maximum drilling temperature of (29.34°C) at same depth, following by normal saline pouring cooling of (32.45°C) and air cooling of (40.28°C) successively. The normal saline spray cooling has the best cooling effect, followed by normal saline pouring cooling and air cooling successively.
