The purpose of this study was to investigate the effect on the vibratory characteristics of a cast hollow obturator prosthesis retainer when varying its bulb height. Bulb parts with high (H), middle (M), and low (L) lateral walls were prepared. A Vibration Generator was used to excite the three obturators, while a Laser-Doppler Vibrometer was employed to detect the vibrations at specified measu...

Maxillary resection results in a discontinuity of the oral nasal and maxillary sinus cavities. Defect of any extent results in significant disabilities experienced by the patient. This may be manifested as difficulties in speech, mastication and esthetics.Prosthetic rehabilitation in the form of a palatal obturator is usually required to cover the defect and restore normal functions. In the cas...

In maxillary defects, role of a prosthodontist is to rehabilitate the intra- and extra-oral structures and to endow with the normal function of mastication, speech, deglutition, and esthetics. Malignancies are common in the oral region and are treated usually through surgical intervention. Surgical intervention creates anatomical defects creating communication between oral and nasal cavity. Pat...
