# Repeated implant analog reuse effect on dimensional accuracy and marginal gap with abutments - An in vitro study

## TL;DR

Repeated use of implant analogs leads to increased dimensional inaccuracies and larger gaps between implants and abutments.

## Contribution

This study empirically demonstrates the impact of repeated implant analog reuse on dimensional accuracy and marginal gaps.

## Key findings

- Implant analogs reused for 5 and 10 patients showed significant dimensional changes compared to unused ones.
- Marginal gaps increased significantly with repeated use (p < 0.001).

## Abstract

The use of same implant analog multiple times affects their accuracy and the distance between the implant and abutment. Hence, 30
titanium analogs were grouped according to how many patients had worn them before (0, 5 and 10). Stereomicroscopy and digital calipers
were used to measure both the marginal gap and dimensional changes. The evidence points to clearly increased differences and dimensional
losses as the parts were used and reused (p < 0.001).
