Restoration of near normal functions in patients who have been treated with hemimaxillectomy is generally difficult, in view of the restriction in mouth opening following healing of large surgical wound. Further, the extent and nature of the surgical defect differ from patient to patient. Thus, design of an obturator needs to be patient oriented. In this report, we describe a novel snap-on attachment with O-ring in a conventional two piece hollow bulb obturator for a 70-year-old male treated for carcinoma of the left maxilla and sinus.

Aim: To find sites in human temporal bone for placing longer implant Materials & Methods: Dry human skull were procured from the anatomy department. External acoustic meatus(EAM) was taken as reference point from that point five arcs of radius15mm, 20mm,25mm,30mm,35 mm were drawn over the temporal bone. The temporal bone removed from the skull and the bone is removed from the outer most point towards the EAM. The thickness of the bone at 1oClock and 4o Clock position and 8oClock and 11o Clock position over the left and right side of the temporal measured using digital Vernier calliper. The temporal bone is thicker at the 3oClock on the left and 9oClock on the right side. The thickness at the new position also measured. Result: The mean bone thickness at 15mm, 20mm, 25mm ranges from 3.92 to 12.08mm. The mean bone Thickness at the 3oclock and 9 o clock position at the distance of 20mm from EAM ranges from 8.21 to 8.50mm.The Statistical significance within the group were analysed using paired t test and found to be statistical significant at P value less than. 05. Conclusion: The external surface of temporal bone at the 3oClock on the left and 9oClock on the right side denser and thicker. The bone availability is also more favours for placing longer implant.
