Oblique Cutting Based Mechanical Model for Insertion Torque of Dental Implant
文献摘要：
The insertion torque of a dental implant is an important indicator for the primary stability of dental implants.Thus,the preoperative prediction for the insertion torque is crucial to improve the success rate of implantation surgery.In this present research,an alternative method for prediction of implant torque was proposed.First,the mechanical model for the insertion torque was established based on an oblique cutting process.In the proposed mechanical model,three factors,including bone quality,implant geometry and surgical methods were considered in terms of bone-qual-ity coefficients,chip load and insertion speeds,respectively.Then,the defined bone-quality coeffiicients for cancellous bone with the computed tomography(CT)value of 235-245,345-355 and 415-425 Hu were obtained by a series of insertion experiments of IS and ITI implants.Finally,the insertion experiments of DIO implants were carried out to verify the accuracy of developed model.The predicted insertion torques calculated by the mechanical model were compared with those acquired by insertion experiments,with good agreement,the relative error being less than 15％.This method allows the insertion torque for different implant types to be quickly established and enhances prediction accuracy by considering the effects of implants'geometries and surgical methods.
