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.

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.
