Influence of Drilling Technique on the Radiographic, Thermographic, and Geomorphometric Effects of Dental Implant Drills and Osteotomy Site Preparations
The aim of this comparative study is to analyze the influence of drilling technique on the
radiographic, thermographic, and geomorphometric e ects of dental implant drills and osteotomy site
preparations. One hundred and twenty osteotomy site preparations were performed on sixty epoxy
resin samples using three unused dental implant drill systems and four drilling techniques performed
with a random distribution into the following study groups: Group A: drilling technique performed
at 800 rpm with irrigation (n = 30); Group B: drilling technique performed at 45 rpm without irrigation
(n = 30); Group C: drilling technique performed at 45 rpm with irrigation (n = 30); and Group D:
drilling technique performed at 800 rpm without irrigation (n = 30). The osteotomy site preparation
morphologies performed by the 4.1 mm diameter dental implant drills from each study group were
analyzed and compared using a cone beam computed tomography (CBCT) scan. The termographic
e ects generated by the 4.1 mm diameter dental implant drills from each study group were registered
using a termographic digital camera and the unused and 4.1 mm diameter dental implant drills
that were used 30 times from each study group were exposed to a micro computed tomography
(micro-CT) analysis to obtain a Standard Tessellation Language (STL) digital files that determined the
wear comparison by geomorphometry. Statistically significant di erences were observed between
the thermographic and radiographic results of the study groups (p < 0.001). The e ect of cooling
significatively reduced the heat generation during osteotomy site preparation during high-speed
drilling; furthermore, osteotomy site preparation was not a ected by the wear of the dental implant
drills after 30 uses, regardless of the drilling technique.OdontologĂ
