Evaluation of the efficiency between single and conventional gradual osteotomy protocolsan in vitro study

Abstract

Introduction: two main protocols were demonstrated in the literature regarding implant site preparation: conventional gradual drilling technique with the use of multiple drills, and single drilling technique using only one drill

Aim of the study: to compare and evaluate the maximum heat generation during preparing 3.7 mm implant site in gradual drilling protocol and single drilling protocol  

Materials and methods: synthetic bone samples were used; the samples were divided into two groups: the control group which is represented by gradual drilling, and the second group which is represented by single drilling.

12 implant site preparation were performed for 3.7 mm implant using the gradual drilling technique, and the same number of preparations within the studied group, and during preparation we took thermal records using the thermal infrared camera to measure the temperature generated during preparation with both techniques.

Results: A statistically significant difference was observed in the generated maximum temperature between the two groups, The control group showed a greater increase in maximum temperatures than the studied group.

Conclusion: single drilling technique reduces the heat generation during preparation of 3,7 mm implant bed, and reduces the time needed for implant site preparation.
