A modified technique and simplified laboratory procedure for ocular prosthesis fabrication

Area of Science:

• Ophthalmic prosthetics
• Biomaterials in dentistry
• Esthetic rehabilitation

Background:

• Stock ocular prostheses often cause discomfort due to poor adaptation to soft tissues.
• Rehabilitating patients with eye loss requires restoring esthetics and function.
• Conventional ocular prosthesis fabrication involves multiple steps and appointments.

Purpose of the Study:

• To present a modified technique for fabricating well-fitting ocular prostheses.
• To reduce laboratory steps and patient appointments.
• To improve the esthetic outcome for patients with ocular defects.

Main Methods:

• Modification of a stock eye shell for the patient's socket.
• Impression making using polyvinyl siloxane material.
• Relining, flasking, dewaxing, and wax pattern fabrication.
• Intraoral try-in of the wax pattern and stock shell.
• Final processing of the ocular prosthesis.

Main Results:

• The technique allows for a custom-fitted prosthesis with improved tissue adaptation.
• Wax pattern try-in and impression procedure can be completed in a single appointment.
• The method facilitates precise positioning of the iris for enhanced esthetics.

Conclusions:

• This modified technique offers an efficient method for ocular prosthesis fabrication.
• Improved fit and esthetics lead to better patient satisfaction and comfort.
• The procedure simplifies the laboratory process while achieving superior results.
