Simplified Technique for Orbital Prosthesis Fabrication: A Clinical Report

Abstract

Loss of orbital content can cause functional impairment, disfigurement of the face, and psychological distress. Rehabilitation of an orbital defect is a complex task, and if reconstruction by plastic surgery is not possible or not desired by the patient, the defect can be rehabilitated by an orbital prosthesis. The prosthetic rehabilitation in such cases depends on the precisely retained, user-friendly removable maxillofacial prosthesis. Many times, making an impression of the orbital area with an accurate record of surface details can be a difficult procedure. The critical areas are making a facial moulage, mold preparation, and attaching the retention device, particularly when eyeglass frames are used. This case focuses on these hindrance factors. A simple basket was used for the impression tray to obtain the facial moulage. A putty mold was used, and attachment of the prosthesis to a retention device was accomplished with positional distance. This method proves to be an economical and simple way of making an orbital prosthesis.

Prosthetic rehabilitation after orbital exenteration: A case series

“…The rigidity of acrylic resin is seldom a problem, as the tissue bed is rarely movable. [45] Silicone materials are preferred nowadays, as they provide better marginal adaptation and more life like appearance than acrylic. But they are expensive and lack the ability of chemical/mechanical bonding with the eyeglass frame.…”

“…Various methods of retention include prosthesis fastened to spectacle frame,[5] anatomic retention using conformer[7] or acrylic resin template relined by a resilient denture liner,[8] adhesives,[910] stud attachments,[11] implants with magnetic attachments etc. [91213] Although spectacle-retained prosthesis is an economical retentive aid but the frame becomes bulky and it becomes mandatory for the patient to wear spectacles every time he wants to use the prosthesis.…”

“…But this can be learnt easily with time. There may also be corrosion or loss of magnetism with time,[5] but unlike other magnets being commonly used; magnetic buttons used here are very cheap and easily available. So, these can be replaced easily without damaging or replacing the existing prosthesis.…”

“…As a result, acrylic resin replaced glass as the preferred material in the fabrication of prosthetic eyes like the one shown in Figure 3a. Unlike with silicone, there is no widely preferred products among acrylic resins, with most studies preferring the use of locally available dental resins with both (Bindhoo and Aruna, 2011;Cevik et al, 2012;Goiato et al, 2012a;Goyal et al, 2012;Ruiters et al, 2016;Shrivastava et al, 2013;Tomar et al, 2018), though many studies in India prefer dental acrylic resin from Dental Products of India (Mumbai, India) (Gupta and Padmanabhan, 2012;Veerareddy et al, 2012;Pruthi and Jain, 2013;Thirunavukkarasu et al, 2014;Tripuraneni et al, 2015;Shankaran et al, 2016;Shetty et al, 2016).…”

Orbital prosthesis fabrication: current challenges and future aspects

“…Type II dental stone (eg, impression plaster) supported by a thin layer of gauze strips has been traditionally used to obtain a facial moulage. Irreversible hydrocolloid (eg, alginate) can serve as a cost-effective alternative impression material, 19 but the material needs to be supported by a customized tray to prevent overflow. It is also susceptible to distortion if not poured immediately.…”
