# Reliability of drilling torque values measured with a novel measurement drill for guiding implant placement protocols

## TL;DR

A new drill measures drilling torque to help choose the best dental implant placement method based on bone density.

## Contribution

A novel drill was developed to measure drilling torque for guiding implant protocols.

## Key findings

- Drilling torque values correlated with insertion torque across different bone densities.
- The novel drill may help select appropriate implant placement protocols.
- Results were tested using polyurethane bone blocks simulating various bone densities.

## Abstract

A novel measurement drill was fabricated to analyze bone density. We hypothesized that evaluating the correlation between primary stability and bone density—assessed using drilling torque values obtained with a novel drill—under various bone density conditions could aid in selecting appropriate implant placement protocols. This study aimed to determine whether drilling torque values measured using the novel drill could serve as a guide for implant placement protocol.

Experiments were conducted using solid rigid polyurethane bone blocks corresponding to Misch classifications D2–D4. After measuring the drilling torque, the implant sockets were prepared under two conditions: undersized and normal-sized drilling protocols. The implant was placed, and the insertion torque value was measured as the primary stability.

A correlation was observed between the drilling and insertion torque values across different bone densities and surgical protocols.

Drilling torque measurements using the novel drill may be a useful method for selecting appropriate implant placement protocols.
