“…2 Numerous varied ways to implant site preparation had been analyzed: (a) traditional preparation, which is the continuing expansion of the drilling location by gradual additions of the drill width;(b) simplified preparation, which contains the decrease in the count of drills by usage of a pilot drill followed by a definite drill; (c) biological preparation, which contains low speed preparation without irrigation for gradual location preparation; and (d) single bur preparation, which have been established with unique drills with four-bladed surface and external irrigation. 3 Concerning the drilling speed, some authors have introduced that there was no significant difference in bone healing from the usage of different drilling velocities. As Ribeiro Junior et al (2007) 4 studied the mandibular bone healing defects done in rabbits using three different rotary protocols.…”

INTRODUCTION:Most implant systems use drilling with irrigation to avoid the overheating of the bone. In the relatively high speed technique, irrigation may not reach the full depth of osteotomy. This triggered the use of low speed drilling technique without irrigation. OBJECTIVES: were the assessment of heat generation and marginal bone loss around implants placed by drilling speed 150 rpm without irrigation compared with implants placed by drilling speed 1200 rpm with irrigation up to one-year follow up. MATERIALS AND METHODS: A total of 12 patients were enrolled in this study. Forty implants were placed bilaterally in the posterior mandibular region. Each patient received the two types of drilling techniques. The temperature of the bone was measured before and after the implant site preparation by thermocouples. The marginal bone loss was evaluated by CBCT. RESULTS: there was statistically different in temperature of bone between the two drilling techniques. Marginal bone loss showed no statistical difference. CONCLUSION: Low speed drilling 150 rpm without irrigation is a successful and applicable drilling technique in implant site preparation regardless of its relatively high temperature, as it did not exceed the critical limit.

“…To avoid this, most implant systems use irrigation as part of the drilling protocol. However, a randomized clinical trial has suggested that drilling without irrigation could be viable and comparable to drilling with irrigation in terms of bone loss and early implant failure at one year of follow-up [5]. This drilling technique without irrigation allows better visualization of the drilling area and better control of the drill and of bone harvesting.…”

In Vitro Study on Bone Heating during Drilling of the Implant Site: Material, Design and Wear of the Surgical Drill

et al. 2020

Objective: An in vitro study was made to compare mean thermal variation according to the material, design and wear of the surgical drills used during dental implant site preparation. Material and methods: Three study groups (stainless steel drills with straight blades; diamond-like carbon-coated drills with straight blades; and diamond-like carbon-coated drills with twisted blades) were tested to compare material, design and wear of the surgical drill in terms of overall mean values (complete sequence of drills) and specific mean values (each drill separately). The groups comprised four drills: initial, pilot, progressive and final drill. Implant site configuration was performed through an intermittent and gradual drilling technique without irrigation at 800 rpm in standardized synthetic blocks. Maximum axial loading of two kilograms was controlled by an automatic press. Each surgical drill was submitted to 50 drillings and was sterilized every five uses. A thermographic camera analyzed the mean thermal changes. The software-controlled automatic press kept systematic drilling, axial loading and operational speed constant without any human intervention. Student’s t-test, ANOVA and multiple linear regression models were performed. The level of significance was 5% (p = 0.05). Results: The overall mean comparison between the stainless steel and diamond-like carbon-coated materials showed no statistically significant differences (p > 0.05), though specific mean comparison showed statistically significant differences between the drills of the different groups (p < 0.05). The twisted blades exhibited less overall and specific mean thermal variation than straight blades for the progressive and final drills (p < 0.01). In addition, the initial and pilot drills showed a greater mean thermal change than the progressive and final drills. The mean thermal variation was seen to increase during the 50 drillings. Conclusions: Within the limitations of this study, it can be concluded that the drill material did not significantly influence the overall mean thermal variation except for the pilot drill. The drill design affected overall and specific mean thermal variation since the twisted blades heated less than the straight blades. The initial and pilot drills increased the specific mean thermal variation with respect to the progressive and final drills. In addition, all drills in each group produced a gradual increase in mean temperature during the 50 drillings.

“…In a randomized, controlled, parallel-group clinical trial, twenty-five patients were recruited. [ 26 ] Fifteen implants were installed in sites prepared using drills at high-speed drilling with irrigation (group A), while fifteen implants were installed in sites prepared using drills at low speed without irrigation (Group B). After 12 months, the success rate at an implant level was 93.3% in group A and 100% in group B.…”

The aim of the experiment was to study the healing at implants installed in site prepared in bone type 1 using different rotation speeds and cooling strategies. The tibiae of twelve sheep were used as experimental sites. Two implant sites were prepared in each tibia using drills either at a high or a mixed speed under irrigation. At the mixed-speed sites, 60 rpm without irrigation were applied for the last drill, the countersink and during implant installation. Biopsies representing the healing after 1, 2, and 6 weeks were obtained and ground sections were prepared. At the histological analyses, after 1 week of healing, no new bone was found at both high- and mixed-speed sites. After 2 weeks of healing, small amounts of newly formed bone were observed in the cortical layer, reaching percentages of 3.6±3.0% at the mixed-speed sites, and of 2.2±1.5% at the high-speed sites. An irrelevant quantity of new bone was seen in the marrow compartments of a few specimens. After 6 weeks of healing, new bone was found in higher quantity, reaching in the cortical compartment 66.9±6.8% and 67.3±17.7% at the mixed- and high-speed sites, respectively. The respective percentages in the marrow compartment were 23.2±13.0% and 30.6±29.2%. No statistically significant differences between high- and mixed-speed groups were found. It was concluded that the use of the last drill and the installation of the implant with or without irrigation yielded similar bone healing and osseointegration.
