[EP-25] A Digital Duplicating Obturator with 3D Printing Technology
[Abstract]
[Introduction]
This presentation explores the application of 3D printing technology in duplicating obturators for bi-maxillectomy patients with edentulous maxillae, aiming to streamline the clinical steps and reduce fabrication time. Traditional methods using materials like alginate and silicone prove challenging due to the complexity of obturators in comparison to conventional dentures (1). The purpose of this presentation is to describe the potential of using 3D printing technology to duplicate an obturator in a bi-maxillectomy patient with an edentulous maxilla with clinical video.
[Case Summary and Treatment Details]
A 66-year-old male patient presented in the hard palate and underwent radiotherapy. Unfortunately, the bone necrosis progressively worsened over time and spread to the adjacent, anterior and contralateral maxillary regions, and an open-type obturator was fabricated with the processing technique (2).When the patient was 74 years old, he complained that the current obturator was unstable and he wanted a new obturator. Therefore, it was planned to fabricate a new obturator using CAD/CAM technology.
[Progress and Discussion]
Sealing stickers were applied to the obturator, scanned with an Intra Oral Scanner, and discrepancies with STL data visually confirmed (Fig.1). A 3D printed obturator was fabricated, adjusted, and applied with tissue conditioner for a two-week trial. After confirming its clinical suitability, the 3D printed obturator was sent to the dental lab for scanning. A secondary 3D printed obturator was delivered (Fig.2). Due to slight lacked nostril retention, auto-polymerization resin was applied and the patient was satisfied with it. Utilizing the intraoral scanner reduced clinical steps and adjustment time, showcasing the synergy of digital and analog technology for improved maxillofacial prostheses in elderly head and neck cancer patients.
