Surgical considerations in the prosthetic treatment of ocular and orbital defects

Prosthetic Rehabilitation of a Huge Midfacial Defect Combined with Partial Mandibulectomy: A Clinical Report

“…An irreversible hydrocolloid facial-moulage was made to record the facial defect along with the surrounding normal extraoral structures, and the extraorally exposed portion of the obturator; and the moulage was cast with type III dental stone (Die-Keen; Columbus Dental Stone, St. Louis, MO) ( Fig 6). The ocular bulb was fabricated in a conventional manner as described by Parr et al (1983). The master cast was isolated (Separating Medium, Factor II Inc., Lakeside, AZ, USA), a wax prototype was carved from pink modeling wax (Lead Dent, Hamle Ltd.…”

Ocular Prosthesis-A Simulation of Human Anatomy-A Literature Review

“…A minimum of one mm thickness is required. Most patients remove the sclera shells at night since the remaining globe is usually very sensitive [11].…”

“…Adequate space is created for fabricating the ocular prosthesis. It is the movement of the fornix in the enucleated socket that provides the mobility to the artificial eye [11]. h. Some type of tissue irregularities in the depth of the socket for the positive adaptation of the prosthesis.…”

“…The eyelids may or may not be involved. Exenteration defects in some instances may be allowed to heal by secondary intent but adequate space must remain in the resultant defect to allow the prosthesis to be positioned superiorly and posteriorly enough for a good cosmetic appearance [11].…”

Principles of Implant Implementations for Restorations of Extra-Oral Defects

“…The magnets used in that system generally have a 6mm diameter and 2mm thickness. The bar-magnet system may create hygiene and aesthetic problems because they increase the volume of the structure which provides the retention [1][2][3][4][5].…”
