(1) Background: The aim of the present in vitro investigation was to evaluate, on polyurethane sheets, two different drilling techniques for dental implant positioning using osteocondensing burs compared to a standard type protocol. (2) Methods: Three different implant designs (Implacil De Bortoli UN III 4 × 10 mm, Restore RBM 4 (HEX) × 10 mm; Implacil De Bortoli UN II 4 × 10 mm) were evaluated (test implant (osteocondensing drills) and control implant (standard drills)). The insertion torque (IT), the removal torque (RT) and the resonance frequency analysis (RFA) values of test and control implants inserted in different size and different density polyurethane foam models were compared for 120 experimental sites. Accordingly, 120 experimental holes were produced in different PCF polyurethane foams: 60 sites were produced in 10 PCF sheets and 60 sites in 10 PCF sheets with an additional 1 mm layer of 30 PCF. (3) Results: The IT, removal torque and RFA values were significantly higher for both of the evaluated implants, in the sites prepared with the osteocondenser drills when compared to sites prepared with standard drills (p < 0.05). The UNII and UN III showed significantly higher stability compared to the HEX implant; these differences increased drastically in the 10 PCF Polyurethane Block with the additional 1 mm cortical layer (p < 0.05). (4) Conclusions: The outcome of this investigation suggested a possible clinical application of osteocondensing burs in case of reduced bone quality and quantity in the posterior maxilla.

“…In this study, a total of 24 drills in zirconia (Dental Tech snc Misinto, Milan, Italy) and 24 steel drills were used (Dental Tech snc Misinto, Milan, Italy), 6 drills for each group (Figures 1 and 2). The sample size was calculated by using a free software (6.0 ClinCalc LLC, North Chicago, IL, USA) available on the site http://clincalc.com/stats/samplesize.aspx considering a power of 0.80, an alpha error of 5% and an effect size of 0.84, based on a previous study [19]: a total of 20 implant osteotomies on bovine ribs for each study group (total 160 sites, 5 osteotomies for each rib) were necessary to achieve statistical significance for quantitative analyses of drill surface damage. All the drills, with the exception of Group 1 and 5 that were controls, were immersed in high protein concentration solutions (10% of fetal bovine serum) (Sigma Aldrich, Milan, Italy) phosphatebuffered saline for 10 min then they were rinsed in running water and scrubbed with a toothbrush made of nylon bristles in order to remove gross foreign material and were then subjected to the different treatments as follows and then analyzed.…”

“…According to a previous study [19], the thermography measurements were recorded in a climate-controlled laboratory conditions (temperature: 24 °C, relative humidity: 50% ± 5% and no direct ventilation on the bone) prior a calibration setting of the camera to a temperature-gauged blackbody and plotting the temperature over 5 min according to the manufacturer specifications.

Background: The aim of this study is to evaluate effects on stainless steel (SS) and zirconia implant drills of 50 cycles of sterilization through different processes. Methods: A total of 24 SS and 24 zirconia drills were treated with 3 different sterilization processes: 50 cycles of immersion in glutaraldehyde 2%, 50 cycles in 6% hydrogen peroxide and 50 cycles of heat. Energy-dispersive X-ray spectroscopy (EDX) was used to compare the effect of the different treatments compared to new untreated controls. Infrared thermography was used to measure the increase of temperature during drilling on bone ribs. A scanning electron microscopy (SEM) was used to measure the roughness of the samples. Results: Zirconia drills seem not to be affected by the different treatments; no significant differences were found with EDX nor through thermography controls. SS drills were affected by the different treatments, as confirmed by the increased roughness of the SS samples after all the cycles of sterilization/disinfection, measured at SEM. On the contrary, the zirconia drills roughness was not particularly affected by the chemical and thermal cycles. Significant differences were observed regarding the temperature, between steel and zirconia drills (p < 0.01). Conclusions: The disinfection agents had a weak impact on the temperature changes during implant bone preparation, while heat sterilization processes had no effect on either of the drills evaluated. The disinfection agents increased the roughness of the steel drills, while they had no effect on the zirconia drills.
