Influence of bone density, drill diameter, Drilling Speed, and irrigation on temperature changes during implant osteotomies: an in vitro study
Clinical Oral Investigations, 2020Co-Authors: Oscar Salomó-coll, Beatriz Auriol-muerza, Naroa Lozano-carrascal, Federico Hernández-alfaro, Hom-lay Wang, Jordi Gargallo-albiolAbstract:Objective The aim of this in vitro study was to evaluate the influence of bone type, drill diameter, Drilling Speed, and irrigation on heat generation while performing osteotomy for dental implants. Materials and methods Six polyurethane foam blocks simulating type I (dense) and type IV (soft) bone were selected for the study. Each block was subjected to two different experimental conditions for each drill (2- and 3.5-mm diameter): three sub-groups were created: (a) revolutions per minute (50, 100, or 800 rpm) and (b) irrigation (with or without irrigation). Results In 2-mm drill group, maximum temperature attained was practically identical: 23.73 ± 2.28 °C in the cortical bone and 23.74 ± 2.03 °C in the cancellous bone. For 3.5-mm, groups showed similar results (25.01 ± 1.88 °C for cortical and 24.05 ± 1.94 °C for trabecular bone). In any type of bone, the presence of irrigating fluid helped to control the maximum temperature ( p = 0.001). When comparing the 2-mm and 3.5-mm drills, most differences were found at 100 rpm without irrigation ( p < 0.001) and at 800 rpm with irrigation ( p = 0.001). Conclusions Maximum temperature attained was always below the critical threshold that can cause osteonecrosis, showing that both external irrigation with higher Drilling Speeds and no irrigation with lower Speeds were effective methods to avoid excessive heat generation. Clinical relevance Despite being always below the critical temperature, bone type, drill diameter, Drilling Speed, and irrigation must be considered temperature-influencing factors during implant osteotomies.

Comparison of stone elimination capacity and Drilling Speed of endoscopic clearance lithotripsy devices
World Journal of Urology, 2020Co-Authors: Markus J. Bader, Maximilian Eisel, Frank Strittmatter, Udo Nagele, Christian G. Stief, Thomas Pongratz, Ronald SrokaAbstract:Purpose To investigate the fragmentation capacity, clearance time, and Drilling Speed of combined ultrasonic with impact dual-energy and single energy ultrasonic lithotripter devices. Methods Stone fragmentation and clearance tests were performed under direct view in an underwater layered hemisphere by four different operators using artificial stones ( n = 10/operator). Time for complete clearance was measured. Drilling tests were performed using an underwater setup, consisting of a mounting rack for fixing the lithotripter handpiece with the probe in vertical position and in contact with the stone phantom placed on one side of a balance for defined and constant contact application pressure equivalent to 450 g load. Time until complete perforation or in case of no perforation, the penetration depth after 60 s into the stone sample was recorded. Four devices, one single energy device (SED), one dual-energy dual probe (DEDP), two dual-energy single probe (DESP-1, DESP-2), with different parameters were tested. Results Stone fragmentation and clearance Speed were significantly faster for dual-energy device DESP-1 compared to all other devices ( p
