A preliminary comparison of masticatory performances between immediately loaded and conventionally loaded mandibular two‐implant overdentures with magnetic attachments

Abstract

Background

Two‐implant overdentures (2‐IODs) is an expected treatment option to improve the masticatory performance (MP) of edentulous individuals.

Purpose

The purpose of the current study was to compare MPs between immediately loaded and conventionally loaded mandibular 2‐IODs retained by magnet attachments.

Materials and Methods

Nineteen participants with edentulous mandibles were randomly assigned to an immediately loaded group or a conventionally loaded group. Each participant received two implants. The immediate group was loaded on the same day as implant insertion, whereas the conventional group was loaded 3 months after implant insertion. Both MP, measured by a color‐changeable chewing gum and a gummy jelly, and maximum occlusal force were assessed at baseline and at 1, 3, 6, 12, 24, and 36 months after implant insertion.

Results

A significantly higher MP, measured by gummy jelly, was observed at the 6‐month time‐point in the immediate group (P = .034). No significant differences in MP, measured by chewing gum, or maximum occlusal force were observed between the two groups at any time‐point.

Conclusions

Within the limitations of the present study, immediate loading of 2‐IODs could improve MP at an earlier time‐point than conventional loading of 2‐IODs.
