A Simplified Approach to Fabricate a Hollow Ocular Prosthesis.

The prosthetic rehabilitation of a large anophthalmic socket is always a challenge. It demands an equally sized ocular prosthesis to replace lost tissue volume. A conventional solid acrylic ocular prosthesis may be deterrent to retention and esthetics because of its weight, which can be reduced by eliminating the mass of material within it. This article attempts to present a simplified and accurate technique to fabricate a hollow ocular prosthesis using silicone putty cavity form. It is removed prior to final processing and serves to ensure appropriate uniform thickness of acrylic resin and optimal weight reduction of the definitive prosthesis without compromising mobility, esthetics, and structural integrity.

A Simplified Approach for Fabrication of a Lightweight Individualized Impression Tray with the Aid of Existing Obturator Prosthesis Using Lost Salt Technique.

Maxillary defects resulting from ablative oncologic surgery can be extensive and usually have complex contours. Impression procedures for such defects can be time consuming and cumbersome, challenging the skills of even the most-experienced clinician. A well-oriented impression tray with proper extension and adequate contour is essential for successfully capturing the relevant details in impression. This article describes a method using the patient's existing obturator prosthesis to simplify and expedite the fabrication of a lightweight individualized impression tray directly on an irreversible hydrocolloid impression, thus avoiding the preliminary impression procedure for the patient.

Alternative Technique of Iris Orientation in a Custom-Made Ocular Prosthesis.

Accurate positioning of the iris is critical for the success of an ocular prosthesis. Precise duplication of size and location of the iris is essential for the establishment of realism, symmetry, and a natural-appearing gaze. This article explores an alternative procedure for positioning the iris in a custom-made ocular prosthesis using a pupillary distance ruler (PD ruler). The orientation and mediolateral dimension of the iris of the natural eye was measured from the graduated scale on a PD ruler and transferred on to the sculpted scleral wax pattern. The iris button was positioned in the marked area, and the established orientation was evaluated for symmetry and a natural-appearing gaze. Accurate, predictable, and easy positioning of the iris with the transfer of these dimensions to the definitive prosthesis provided a good result in terms of patient esthetics and satisfaction.

Simplified technique for the prosthodontic rehabilitation of a patient with a segmental mandibulectomy with a hollow cast partial dental prosthesis: A clinical report.

Rehabilitating patients with a mandibulectomy defect is a challenging task as such surgical resections may result in discontinuity defects that pose functional, esthetic, and psychological problems. A decreased denture-bearing area, increased interarch space, and lever action in such maxillofacial defects may cause problems with regard to retention, stability, and support of the prosthesis. Reducing the weight of the prosthesis helps to decrease the lever action and load on the residual alveolar ridge. This clinical report describes how a patient with a posterior segmental mandibulectomy was rehabilitated with a hollow cast partial dental prosthesis using a simplified technique with expanded polystyrene.
