Evaluation of Immediate Bone-Cell Viability and of Drill Wear After Implant Osteotomies: Immunohistochemistry and Scanning Electron Microscopy Analysis

Heat generation and drill wear during dental implant site preparation: systematic review

“…28 In 3 animal studies, immunohistochemical analysis was done to check the viability of bone cells. [29][30][31] The work of Strbac et al to achieve standardisation and reproducibility of test results using a new standard bone model is a positive step. 21 Use of artificially manufactured bovine bone provided equal vertical and horizontal variables.…”

“…4 Recent studies have investigated the wear of the drill itself. 2,[12][13][14]17,29,30,38 Descriptive analyses have been done using scanning electron microscopy, and mechanical studies have been based on the electrical power from the torque and tension of the drill. The objective of these studies was to measure the durability of twist drills after multiple uses and the effect on the bone.…”

“…The waste of drills used for dental implant surgery was the focus in recent studies. Until now, scanning electron microscopy (SEM) has been used to analyse wear of the drill, 2,12,14,17,29,30,38 and qualitative analysis of bony healing has been done immunohistochemically. 2,[29][30][31] SEM has shown small defects on new drills 38 and a high correlation between the amount of damage and number of uses has been seen.…”

In-situ tool wear monitoring and its effects on the performance of porcine cortical bone drilling: a comparative in-vitro investigation

“…They reported that drill tool was worn after being used a number of times. (Queiroz et al 2008) performed the study on a rabbit's tibiae to investigate the effect of repeated drill bit (40 times) on the bone cell viability. They concluded that cell viability decreased in the bone matrix using a repeated drill bit.…”

“…Cutting forces (Alam et al 2009;Alam et al 2011;Wang et al 2014a) and torque (Alam et al 2011;Wang et al 2014a) should also be minimum. Using a drill bit repeatedly increased the temperature (Jochum and Reichart 2000;Allan et al 2005;Chacon et al 2006;Queiroz et al 2008;de Souza et al 2011;Oliveira et al 2012) and force (Staroveski et al 2015) significantly which may cause to decrease the strength of internal fixation (Allan et al 2005).…”
