Rehabilitation of maxillary defect with an interim obturator
An interim obturator acts as a bridge between surgical and definitive phases of treatment of a maxillectomy patient. Apart from restoring the functions of speech and deglutition, it has a great psychological benefit to the patient in regaining social acceptance.

For the success of an obturator it should cover maximum supporting area, utilizing all the favourable undercuts and utilizing the remaining teeth and reduction of the weight of the obturator is important. This case report, published in the International Journal of Dentistry Research, describes a modified technique for fabricating an overdenture with closed hollow bulb obturator.

A 50 years female patient came to the prosthodontics 10 days after surgery with the chief complaint of missing teeth, difficulty in eating & drinking water, foul smell from mouth, speech difficulty. Patient was an operated case of left subtotal maxillectomy for Squamous cell carcinoma.

The site of surgery was the part of left maxillary hard and soft palate. Extension of defect- Anteroposteriorly - first molar tooth region to a part of soft palate.

Mediolaterally - mid alveolar ridge beyond 2nd premolar tooth till midline of hard palate. A few teeth were also extracted on that side. The missing teeth were 26 and 27. Intraoral examination revealed raw wound at the operated site.

Patient was planned for prosthetic rehabilitation with Interim Obturator with minimum extension into defect area until surgical closure was performed.
