Bone height changes around immediately loaded implants splinted with prefabricated bar attachment for mandibular over dentures

Abstract EN

Mandibular implant-retained overdenture (IOD) is an especially attractive treatment because of its relative simplicity, minimal invasiveness and economy.

The high activity in applying immediate/early loading protocols is indicated by an increasing number of publications and conference abstracts.

Splinting of immediately loaded implants by a bar, prevent micromovement and hence improve osseointegration in addition to improvement of overdenture retention.

Recently, pre-fabricated bars can be placed directly on immediately loaded implants to retain mandibular overdenture.

This study was aimed to evaluate the bone height changes around immediately loaded implants splinted with pre-fabricated bar to retain mandibular overdenture.

Six completely edentulous healthy males were selected for this study.

For each patient, two standardized size; of 13 mm length and 3.6 mm width; screw-type implants were surgically inserted in the canine areas and splinted with pre-fabricated bar to retain immediately loaded mandibular overdenture.

Along the first and second six months after overdenture insertion, the bone height changes were evaluated radiographically to measure the peri-implant marginal bone loss and the results were statistically analyzed.

Within the limitations of this study, it can be concluded that splinting of immediately loaded implants with prefabricated bar attachment to retain mandibular implant overdenture can be considered as a successful prosthetic approach for preserving the peri-implant marginal alveolar bone.
