Rehabilitation of a total maxillectomy patient by three different methods

Rehabilitation of a patient with orbital defect is highly a challenging task, requiring an individualized design of the technique for each patient. The disfigurement associated with the loss of facial structures causes significant emotional stress and physical burdens.Various treatment modalities are available, one of which is the use of implants. Although implant-supported orbital prosthesis has a superior outcome, it may not be advisable in all the patients due to economic factors. The treatment of choice includes the silicone orbital prosthesis due to its life-like appearance. This article describes three different techniques, it's advantages and limitations of fabricating a silicone orbital prosthesis for the same patient to achieve ideal fit and aesthetics.

A unique method of retaining orbital prosthesis with attachment systems - a clinical report

Diminution of the orbital contents post-surgical removal of a malignant tumor can have a severe psychological impact on the patient in terms of function and esthetics. Therefore, esthetic remedy should be planned subsequently, since tumor obliteration precedes cosmetic concern. A convenient option for successful rehabilitation in such patients is a simple, user-friendly, removable orbital prosthesis. Retention of the prosthesis is one of the key factors for the successful rehabilitation. Spectacle frame, conformers, adhesives, osseointegrated implants, magnets or buttons have been used to impart retention to the prosthesis. The use of semi precision attachments in maxillofacial prostheses is limited to the osseointegrated prostheses. This case report describes a conventional spectacle frame technique, to retain the silicone orbital prosthesis using two different types of stud attachments viz., dalla bona and O-ring attachment systems.

Rehabilitation of a patient with an intra oral prosthesis and an extra oral orbital prosthesis retained with magnets

This clinical case report deals with a rehabilitation of a patient with an extensive maxillary and orbital defect using an intra oral prosthesis obturating the maxillary defect and extra oral orbital prosthesis retained with rare-earth magnets for secondary retention; primary retention was derived by snug fit of the prosthesis to underlying and adjacent tissues. The rehabilitation resulted in improved function, esthetics and comfort to the patient thus enabling him to lead a normal life.

Prosthetic rehabilitation of a patient with a large mid face defect secondary to Basal cell carcinoma

The art of maxillofacial prosthetics restores esthetics and function in patients with gross developmental or acquired defects of face and helps them to restore hope and ambition to lead a useful life. This valuable service provided by maxillofacial prosthodontist lifts the morale of the patient and thus aids in physical well being and quality of life. Diagnosis and treatment planning should include attention to each detail prior to rehabilitation process. This paper describes a clinical case of mid face defect due to basal cell carcinoma, rehabilitated with facial prosthesis and intraoral obturator.

An alternative approach to combine orbital prosthesis and obturator: a case report

This report describes a different approach for diminishing the movements of orbital prosthesis during mimic movements and chewing function. Mechanical devices such as magnets are used to enhance the retention in case lack of the implants. However rigid fixation of obturator and orbital prosthesis can result in movements of the orbital prosthesis during mastication. In this case obturator and orbital prosthesis are combined by magnets. However this combination is not rigid because of an active part which provides movement. This active part allows movements in a space constructed in the acrylic base of orbital prosthesis. Thus, the movements that may occur on orbital prosthesis during chewing can be diminished by this simple mechanism. Due to the fact that designing such a mechanism that minimizes the movements of the orbital prosthesis contributes patient's comfort.

A novel method for retention of an orbital prosthesis in a case with continuous maxillary and orbital defect

Exenteration of the orbital contents as well as removal of a part of maxilla with an ablative surgery for the removal of a malignant tumor can severely affect a person in terms of function, esthetics and psychological trauma. A well-retained, user-friendly, removable maxillofacial prosthesis is the key to successful prosthetic rehabilitation in such cases. Various retentive techniques include using spectacle frame, conformers, adhesives, osseointegrated implants, magnets or buttons. This paper describes a novel technique for retention of silicone orbital prosthesis using acrylic resin base attached to maxillary obturator with the help of pin and socket of an electric plug wherein the latter is attached to the eye prosthesis with the help of a mechanical undercut. This helps in better retention of both the prostheses.
