Background:

Maxillectomy defects often require obturator prostheses for restoration.
Traditional obturator fabrication can be time-consuming and complex.
Advancements in visible light-cured (VLC) materials offer new possibilities in prosthodontics.

Purpose of the Study:

To describe a novel technique for fabricating an open combination (hard-resilient) obturator prosthesis.
To utilize VLC denture resins and resilient liners for improved prosthetic outcomes.
To present an efficient method for patients undergoing partially edentulous maxillectomy.

Main Methods:

Fabrication of an open combination obturator prosthesis using VLC denture resins and resilient liners.
Modification of prosthesis thickness and resiliency based on clinical needs.
Utilizing rigid scaffolding for enhanced structural support when required.

Main Results:

The technique allows for rapid fabrication, saving time for patients and clinicians.
The resulting obturator prosthesis offers a stable record base for jaw relation records.
Flexibility and resiliency are easily managed, and prostheses are readily repairable.
The VLC obturator prosthesis provides enhanced stability, retention, decreased weight, and reduced obduration of palatal defects.

Conclusions:

This technique offers a valuable treatment modality for maxillofacial prosthodontists.
The combination VLC obturator prosthesis is suitable for partially or fully edentulous patients post-maxillary resection.
The method provides a stable, retentive, and lightweight obturator with manageable flexibility.
