Implantation cysts result from implantation of epithelial cells on the iris after penetrating or surgical trauma, which may lead to a solid (pearl) mass, a fluid-filled (serous) cyst, or epithelial ingrowth. Such lesions can, in turn, cause corneal edema, uveitis, glaucoma, and decreased visual acuity.bjective To correlate the clinical, histopathologic, and ultrasound biomicroscopic characteristics of anterior segment implantation cysts.Methods We performed a retrospective review of 7 cases of secondary anterior segment implantation cysts.
Most partial denture frameworks use an alloy or mixture of metals. These are typically gold, nickel, or chromium alloys. Full dentures rarely contain metals. There are partial dentures available today that are made without metal. Most partial denture frameworks use an alloy or mixture of metals. These are typically gold, nickel, or chromium alloys.

A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw. A fixed bridge replaces one or more teeth by placing crowns on the teeth on either side of the space and attaching artificial teeth to them. This bridge is then cemented into place. Not only does a partial denture fill in the spaces created by missing teeth, it prevents other teeth from changing position.
