Defects in the jaw and face area are caused by congenital anomalies and some infections. In this study, we present a case of palatal insuffi ciency after maxillectomy, treated with shutter which was applied to ensure the aesthetics, phonation and functional defi ciency of the patient. After epithelialization of the defect of maxillectomy, the patient was informed about the technique. Problems of prosthesis for the patient, retention, stability and insuffi ciency of tissue support are detailed. Further, we present the successful rehabilitation with the hollow bulb obturator.

This study aimed to compare the crestal bone loss between a two implant-supported, non-cantilevered three-unit fixed partial prosthesis (TUFPP) with sinus augmentation and a two implant-supported, distal cantilevered TUFPP without sinus augmentation in the posterior maxilla having insufficient crestal bone. The study subjects were enrolled into two groups. Group 1 included patients with two implants, an anterior implant placed in the native bone and a posterior implant inserted with simultaneous sinus augmentation using a xenogenic bone graft to support a TUFPP, and group 2 included patients with two implants inserted in the native bone to support a distal cantilevered TUFPP. The crestal bone levels at the distal and mesial aspects of each implant were measured at baseline and 6-, 12-, and 24-month follow-up controls on panoramic radiographs. Fifty-two patients and 104 implants were included. There was a significant difference in distal crestal bone loss between anterior and posterior implants in group 1 at 6 months (p<0.05), but not at 12 and 24 months (p>0.05). Distal crestal bone loss was significantly increased in group 1 posterior implants compared to the group 2 posterior implants at 6 months (p<0.05). There was no significant difference in mesial bone loss between the anterior and posterior implants in both groups at all follow-up controls (p>0.05). There was also no significant mesial crestal bone loss in relation to the anterior and posterior implants of both groups at all follow-up controls (p>0.05). Non-cantilevered two implant-supported TUFPP with sinus augmentation may have similar medium term crestal bone loss when compared to cantilevered two implant-supported TUFPP without sinus augmentation. Further prospective studies should be designed to compare the performance of the two implant-supported cantilevered TUFPP and two implant-supported TUFPP with sinus augmentation.
