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.
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.
Dental implant has been established as one of the most predictable and conservative approaches for the rehabilitation of missing teeth. With the evolution of newer material and advancement in digital technology, specially in computed tomography, implant planning software and guided implant surgery, the outcome and success in implant dentistry has become more predictable. Computer aided design (CAD) technique is being integrated into treatment planning, and computer-assisted manufacturing (CAM) is becoming more popular for rehabilitation procedures. This case report illustrate the diagnosis, planning and application of 3D guided technology in dental implant surgery
Facial defect rehabilitation is a very critical task which requires personalized design of the prosthesis for each patient. Eyes are vital organ not only for vision but also for the facial expression. Disfigurement due to loss of an eye and associated structures may cause physical and psychological distress to the patient. Rehabilitating such patient with a removable orbital prosthesis is an economical and patient-friendly procedure which restores the patient's social as well as the cosmetic value. The present article describes a conventional technique for the fabrication of a spectacle retained acrylic resin orbital prosthesis providing accurate and effective rehabilitation.
