The unilateral “Sub” is used either in the upper or lower jaw as a support for fixed bridgework, usually to replace a partial denture. The unilateral “Sub” is used in patients who have lost much of their jaw bone structure due to resorption caused by aging, by dental disease, or by wearing partials. This type of implant is tailored to fit over the patient’s jaw bone and is held in place by tissue attaching itself over the implant. The patient can then be fitted with a fixed bridge which is much stronger, better fitting and more stable than a partial denture.
