Tooth Drilling Procedures are associated with the rise of temperature in osteotomy sites. Most of the studies on this topic were made in vitro, and different temperature values were observed.

Temperature values were observed. Temperature values ranging from 40° – 50°C to 130°C, during in vitro drilling procedures, were reported. The temperatures recorded by different authors are so diverse. There are many factors involved in frictional heat generation. Among these, careful irrigation could significantly reduce the in vitro results about the risk of bone overheating during implant procedures was also supported by an in vivo study on the human femoral cortex that showed a temperature bone value of 89° C during implant site preparation under saline cooling.

Tooth Drilling Procedures are causing overheating

During implant drilling, temperatures between 47°C and 56°C have been considered to be responsible for irreversible bone injury caused by tooth drilling procedures. According to many authors. The most cited paper about the temperature threshold level for irreversible bone damage is the study by Eriksson and Albrektsson. The authors focused their attention on the temperature level, beyond which, the bone loses its growth capacity inside a customized bone growth chambers model.
