Abstract
Objective: The purpose of this research was to adapt a normal or undersized implant preparation protocol for different bone densities depending on the density measure (Implant stability quotient ISQ, Newton centimeter NCM) and from Cone Beam Computed Tomography reading pre-surgically. To eliminate the need for practice and experience in inserting implants in poor bone quality areas to enhance implant primary stability and survival rate. Material and methods: Fifty-nine patients were selected for inclusion in the study. A total of fifty-nine implants were placed. Insertion torque data were recorded, resonance frequency analysis measurements were taken at first stage surgery, and Hounsfield Unit HU was assessed before surgery and kept hidden to prevent bias. The implant preparation protocol divided the patients into two groups whether standard or undersized, which was determined according to the tactile sensation of the operator. Depending on primary stability measures (ISQ, NCM) samples were divided into 4 subgroups. Finally, HU measurements were taken from subgroups with high stability measures to assess whether to do a standard or underprepared surgical preparation. Result: the result showed a positive and strong correlation with a high significance between ISQ, HU, and insertion torque.
