The effects of irrigation volume to the heat generation during implant surgery

Abstract

BackgroundTo evaluate the effects of the amount of irrigation on heat generated during implant site preparation.Material and MethodsTen freshly dissected sheep mandibles were sectioned into 30 equal bone blocks and transferred into a heat-controlled water tank. Implant socket preparations were performed with four consecutive drills. Temperature measurements were performed with a thermocouple inserted into the bone immediately before the preparation and after the drilling using three different physiologic saline irrigation set-ups: 1- No irrigation, 2- 12 ml/min and 3- 30 ml/min irrigation volume. The temperature differences between three different irrigation set-ups for implant drills 1, 2, 3 and 4, and the temperature differences between the drills for three different irrigation set-ups were separately compared.ResultsThe temperature difference of no irrigation group was significantly higher than 12 ml/min and 30 ml/min groups for all four drills (p<0.05), whereas no statistically significant difference was found between 12 ml/min and 30 ml/min irrigation groups. (P >0.05) The temperature difference of drill 1 is significantly higher than drills 2, 3 and 4 for no irrigation group. (P <0.05) The temperature differences of drill 1, 2 and 3 were significantly higher than the temperature difference of drill 4 for 12 ml/min irrigation group. (p<0.05).ConclusionsThe heat generated during drilling is not directly proportional to the coolant volume. Given that certain amount of irrigation is applied, implant sites can be prepared safely without the need for additional irrigation, which may result in reduced visibility of the surgical site and therefore a suboptimal surgery.

Does the Intake of Selective Serotonin Reuptake Inhibitors Negatively Affect Dental Implant Osseointegration? A Retrospective Study

“…R eplacement of missing teeth in partially and totally edentulous patients with osseointegrated dental implants is extensively practiced worldwide with high success rates and predictability. 1 Despite a success rate of up to 92%, 2 dental implant failures still occur and remain a significant concern for both the patients and clinicians. 3 Several factors, including the quality and quantity of the residual bone, primary stability at the time of implant placement, and formation of direct bone to implant contact, may influence the overall success and survival of implants.…”

Appraising efficiency of OpSite as coolant in drilling of bone

“…They indicated that while there are several parameters that increase bone temperature during drilling, cooling (as external irrigation in their case) can be the only and the most important factor in limiting this increase in bone temperature and must be used for bone drilling. On the other hand, Shakouri et al [3], Sener et al [17], Al-Dabag and Sultan [23], and Sindel et al [24] determined the efficiency of external cooling with normal saline as coolant. They also indicated similar positive influence in limiting the maximum temperature elevation.…”

Evaluation of Thermal Variations of Irrigation on the Osseointegration of Dental Implants: An In vivo Study in Rabbit Models.

“…Different determinants may be contribute in the effect of irrigation solution on thermal trauma. [16][17][18][19][20][21][22]24 However there is limited information in literature, regarding the impact of irrigation solution tempature on current issue. 24,33 An interesting study pointed out the effect of irrigation solution tempature on heat control.…”

“…8,9 To overcome the unwanted effects of thermal trauma many in-vitro and in-vivo studies evaluated the potentialindicator of thermal trauma. 4,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] They concluded multiple factors assosicated with the condition e.g: drill speed 10,11 , drill material 12 , drilling technique 13 , drill diameter 14 , drill configuration 4 , bone type 15 , irrigation method 16,[17][18][19][20] , irrigation solution volume 21,22 , and surgical technique. 23 Irrigation solution tempature is also one of the crucial indicator which effect thermal trauma.…”
