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.
