METHODS Twenty-four healthy volunteers in need of sinus floor elevation were included in the study. The lateral approach was adopted placing the antrostomy randomly either close to the level of the sinus floor (group A) or approximately 3-4mm cranially (group B). Cone-beam computed tomography (CBCT) was done before surgery (T0) and after 1week (T1) and 9months (T2), and analyses on dimensional variations were performed. RESULTS CBCT of 10 patients per group were analyzed. At T1, the sinus floor was found to be elevated by 9.8±2.1mm in group A and 10.9±1.9mm in group B. At T2, shrinkage of 2.0±1.7mm in group A and 1.4±2.5mm in group B was observed. The area was reduced approximately 18-24% between T1 and T2. The sinus mucosa width increased by 4.3-5mm between T0 and T1, and regained the original dimensions at T2. CONCLUSIONS The more cranial the antrostomy, the greater the augmentation height after 9months.
