What is a common issue related to bar overdentures with implants?

The use of the wrong screw is a common issue related to bar overdentures with implants. This can occur when the fasteners utilized to secure the bar to the implants are not appropriate for the specific system or design being used. Each implant system typically has its own specifications for screws, which are designed to provide optimal stability and functionality. If the incorrect screw is used, it may lead to inadequate retention, increased risk of screw loosening, or potential failure of the attachment system.

Improper selection of screws can compromise the integrity of the connection between the implants and the bar, leading to clinical complications such as mobility of the overdenture, difficulty in retention, or even fracture of components. Therefore, it's crucial to ensure that the correct screws are selected according to the specifications of the implant system being utilized.

In contrast, implant alignment issues, suction concerns, and bar length are all potential complications that warrant attention, but they do not directly address the critical aspect of screw selection, which is foundational for the stability and longevity of bar overdentures.
