A modified technique and simplified laboratory procedure for Ocular Prosthesis Fabrication

Abstract

PurposeIn many cases dentist tries to satisfy the patient with stock prosthesis that comes in standard sizes, shapes and colors. However, most of the patients complain of discomfort even after appropriate adjustment because of insufficient adaptation to underlying soft tissues. The rehabilitation of a patient with loss of eye as a result of congenital defect, pathology or accidental trauma is a challenge in terms of re-establishment of the esthetics of the patient. The purpose of this technical procedure is to provide a well fitting prosthesis to the patient, reducing the number of laboratory steps and appointments for fabrication of ocular prosthesis. MethodA suitable stock eye shell was modified to fit the eye socket, followed by relining with low fusing compound and making a final impression with polyvinyl siloxane impression material. The impression was poured in die stone, flasking procedure was accomplished. After dewaxing, molten wax was flown in the lower half of the flask followed by repositioning of the upper half. The flask was reopened, the stock eye shell along with the hardened wax on tissue surface was tried in the patient's eye. Finally processing was done. ConclusionThis technique describes an impression procedure, followed by a wax pattern try-in in the same appointment and also the detailed laboratory procedure for fabrication of the ocular prosthesis, taking into consideration positioning of iris as a result enhancing the esthetic appearance of the patient.
