# Mechanical performance of narrow dental implants with varying lengths and angled abutments

## TL;DR

This study compares the mechanical strength of narrow dental implants with different lengths and angled abutments under static and fatigue loads.

## Contribution

The study reveals that longer implants have higher static strength while shorter ones perform better under fatigue.

## Key findings

- Group 1 (3.5 mm x 10 mm, 25° abutment) showed 418 N static and 182 N fatigue resistance.
- Group 2 (3.5 mm x 25 mm, 45° abutment) showed 454 N static and 160 N fatigue resistance.
- Shorter implants performed better under fatigue conditions compared to longer ones.

## Abstract

Mechanical performance of narrow-diameter dental implants with varying lengths and abutment angulations remains a critical factor in
long-term clinical success. Therefore, it is of interest to evaluate Quickdent implant systems under static and fatigue loading according
to ISO 14801:2016E. Group 1 (3.5 mm x 10 mm, 25° abutment) and Group 2 (3.5 mm x 25 mm, 45° abutment) were tested using fifteen
assemblies per group. Group 1 showed 418 N static and 182 N fatigue resistance, while Group 2 showed 454 N static and 160 N fatigue
resistance with distinct failure modes. Thus, we show that longer implants offer higher static strength, whereas shorter ones perform
better under fatigue conditions.
