Patients with maxillofacial defects secondary to the removal of benign and malignant pathologies of midface have a profound impact on quality of life. The aim of this study was to collect and analyze the data pertaining to 4 designs of obturator by assessment of the patient with obturator functioning scale (OFS)

Materials and Methods:

This retrospective analysis included all the patients who underwent prosthetic rehabilitation of maxillary defects using 4 different types (conventional, cast partial, hollow bulb, and magnet retained) of obturators from 2009 to 2016 with minimum 1 year of follow up. Demographics, number, size, location, type of pathology, postmorbid dentition, and the treatment rendered were recorded. Obturator functioning scale was used to subjectively assess the patient satisfaction.


The mean score on OFS was 5.67 (standard deviation: 1.8). There was a fair and statistical improvement in chewing/eating, speech clarity in public/on phone, swallowing of foods and liquids, pronunciation of words, and social interaction (P < 0.05). The outcome was best in magnet retained followed by cast partial group. The least outcome was in conventional obturator group.


Obturators of different designs do play an important role in rehabilitation of maxillary defects with a satisfactory outcome.
