Effect of implant drill characteristics on heat generation in osteotomy sites: a pilot study

Abstract

Within the limitations of this pilot study, the observations herein suggest that reduction in contact area between the drill and bone reduces heat induction. Further studies to optimize drill/bone contact dimensions are needed.

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

“…It is clear that a reduction in the diameter and the lateral cutting surface has a positive effect, 27 and that a conical design seems advantageous, but the material of the bur is less important. 4,19 New information about the effect of heat on bony healing has come to light.…”

“…Thermocouples, which enable direct measurement, 3,5,7,13,[15][16][17][18]23,24,26,35 were first reported in implant dentistry by Horch and Keiditsch. 36 Infrared thermography provides an indirect estimate, 4,18,22,27 and measurements were first described by D'Hodet et al 37 Although thermocouple technology is well established, studies on its use are still not uniform (Table 1), and there are variations in the distance to the final cut (between 0.5 and 2 mm), configuration of the elements (from mono to tripod), and depths and numbers in the vertical dimension (monochannel and multichannel). Another problem is the ability only to detect spot temperatures.…”

“…41 Oh et al evaluated the heat produced by different designs of drill. 27 They modified conventional triflute drills by reducing the diameter and setting the lateral cutting surface, and used an unmodified triflute drill as control. The results showed that the mean change in temperature for all combinations of modified drills was significantly smaller than for the control, which suggests that a reduction in the area of contact between the drill and bone reduces the amount of heat produced.…”

“…2,[12][13][14][15][16][17][18][19][20][21][22][23][24][25] Three studies used synthetic blocks, 21,26,27 and one a resin model. 28 In 3 animal studies, immunohistochemical analysis was done to check the viability of bone cells.…”

An Experimental Research on Bone Drilling Temperature in Orthopaedic Surgery

“…Further associated research is needed. Furthermore, most previous researches are based on experimental exploration [33][34][35][36][37][38][39][40][41][42][43][44][45]. They involve more variables, but lack of corresponding theoretical supports.…”
