# Effect of the implantoplasty techniques on the fracture resistance of dental implants. Systematic review and meta-analysis

## TL;DR

This study compares how different implantoplasty techniques affect the strength of dental implants, finding that tungsten carbide drills cause less strength loss.

## Contribution

The study provides a meta-analysis comparing fracture resistance of dental implants treated with different implantoplasty tools.

## Key findings

- Tungsten carbide drills caused less fracture resistance loss compared to diamond drills.
- The overall analysis showed a significant decrease in fracture resistance after implantoplasty.
- High heterogeneity was observed among the studies included in the meta-analysis.

## Abstract

The aim of this systematic review and meta-analysis was to analyze and compare the effect of diamond drill, tungsten carbide drill and ultrasound tips for implantoplasty procedures on the fracture resistance of dental implants affected by periimplant disease.

This systematic review of the scientific literature and meta-analysis was carried out based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), analyzing all studies that evaluated the fracture resistance of dental implants submitted to implantoplasty through diamond drill, tungsten carbide drill and ultrasound tips for implantoplasty procedures, comparing with the fracture resistance values of non-treated dental implants. A total of 4 databases were searched in the literature: Pubmed, Scopus, Cochrane and Web of Science. After eliminating duplicate articles and applying certain inclusion criteria, a total of 9 articles were selected and compared using the random effects model and inverse variance method. The significance of the effect size was measured with the z test, the heterogeneity using the Q test and the I2 and publication bias was analyzed using the trim-and-fill method

The difference in means between the treatment and control groups was estimated as the effect size, obtaining a statistically significant difference of −232.01 MPa., with a 95% confidence interval of the difference between −417.3 and −44.71 (z test = −2.43; p-value = 0.015). The meta-analysis has presented high heterogeneity with an I2 = 99.3% and a Q test = 2,195.7; p-value < 0.001. No significant differences were found between the three subgroups with the Q test = 0.20: p-value = 0.903.

the tungsten carbide drills resulted in less fracture resistance loss than the diamond and tungsten carbide drills for the dental implants submitted to implantoplasty procedures.
