A maxillofacial prosthetic obturator using precision attachments.

Area of Science:

• Oral and Maxillofacial Surgery
• Prosthodontics
• Reconstructive Dentistry

Background:

• Maxillary defects often require obturator prostheses for rehabilitation, especially after large resections where flap viability is uncertain.
• Conventional hollow bulb clasp-retained or implant-retained obturators may present challenges with retention, stability, and support, particularly in cases of recurrence.

Observation:

• Precision attachments, specifically extracoronal resilient types, have been utilized for retaining obturators in maxillectomy patients.
• This clinical report focuses on the prosthetic rehabilitation of significant maxillary defects using obturators retained by two distinct extracoronal resilient precision attachments.

Findings:

• Attachment-retained obturators successfully close maxillary defects, offering improved aesthetics, retention, tolerability, mastication, and speech.
• The use of precision attachments in dentate maxillectomy patients leads to significant functional improvements and maintains the aesthetic benefits of the obturator prosthesis.

Implications:

• Precision attachments represent a viable and effective solution for complex maxillary reconstruction, enhancing patient quality of life.
• This prosthetic approach provides a reliable alternative for managing large maxillary defects, improving functional outcomes and patient satisfaction.
