Area of Science:

Oral and Maxillofacial Surgery
Prosthodontics
Reconstructive Surgery

Background:

Maxillectomy, the surgical removal of the upper jaw, presents significant challenges in restoring function and aesthetics.
Reconstruction often involves obturator prostheses to manage the resulting defect.
Conventional prostheses are an alternative to implant-retained options, potentially avoiding further surgical procedures.

Observation:

A hollow box obturator was designed and utilized for a patient following maxillectomy.
Skin grafting of the maxillary defect and strategic use of anatomical undercuts were crucial for obturator support and retention.
The lightweight nature of the hollow obturator contributed to improved retention and speech resonance.

Findings:

The constructed hollow obturator effectively addressed functional and aesthetic deficits post-maxillectomy.
Successful retention and good speech resonance were achieved with the lightweight prosthesis.
A conventional obturator prosthesis met the patient's needs, negating the necessity for implant surgery.

Implications:

This case highlights the efficacy of well-designed hollow obturators in maxillectomy rehabilitation.
The technique emphasizes optimizing prosthesis retention through anatomical considerations and defect management.
Conventional prostheses can provide satisfactory outcomes, offering a less invasive alternative to implants in select cases.
