A method for orienting the ocular portion of an orbital prosthesis

Area of Science:

• Ophthalmology
• Prosthodontics
• Medical Imaging

Background:

• Successful orbital prosthesis rehabilitation requires precise anatomical orientation.
• Current methods for positioning orbital implants can be time-consuming and complex.
• Accurate placement of the ocular bulb and pupil is crucial for aesthetic and functional outcomes.

Purpose of the Study:

• To present a novel method for accurately orienting the pupil and ocular bulb for orbital prosthesis fabrication.
• To reduce the chairside time required for orbital prosthesis fitting.
• To improve the overall success rate of orbital prostheses through simplified positioning.

Main Methods:

• Utilizing a transparency projection to capture facial landmarks.
• Creating a tracing of prominent facial features from the projection.
• Transferring these facial dimensions to a patient's facial cast for prosthesis guidance.

Main Results:

• The described method provides a reproducible means of determining pupil and ocular bulb orientation.
• Transferring traced facial dimensions to the cast significantly decreases the time needed for accurate positioning.
• This technique facilitates more efficient and precise placement of orbital implants.

Conclusions:

• The transparency projection tracing method offers an effective solution for accurate orbital prosthesis orientation.
• This approach streamlines the fitting process, reducing patient and clinician chairside time.
• Implementing this technique can lead to improved functional and aesthetic results in orbital implantology.
