Abstract

<abstract xml:lang="en" abstract-type="author" id="abs0010"> <title id="sectitle0010">Abstract</title> <sec> <title id="sectitle0015">Objective</title> <p id="abspara0010">The aim of this study was to evaluate the anatomical feasibility of palatal sinus floor augmentation.</p> </sec> <sec> <title id="sectitle0020">Material and methods</title> <p id="abspara0015">In 100 men and 100 women, both sinuses were analyzed using computed tomography. The patients were divided into four anatomical groups according to the remaining alveolar bone height: group 1 (0 ≤ × &lt; 4), group 2 (4 ≤ × &lt; 8), group 3 (8 ≤ × &lt; 12), and group 4 (≥12).</p> </sec> <sec> <title id="sectitle0025">Results</title> <p id="abspara0020">The 400 maxillary sinuses consisted of 23.5% (n = 94) group 1, 42.75% (n = 171) group 2, 23.5% (n = 98) group 3, and 9.25% (n = 37) group 4 sinuses. Optimal anatomical preconditions for palatal sinus floor augmentations (i.e., ≥5 mm height and &lt;5 mm thickness of the window lid) were found in 93.6% of group 1 sinuses, 73.7% of group 2 sinuses, 23.5% of group 3 sinuses, and 5.4% of group 4 sinuses.</p> </sec> <sec> <title id="sectitle0030">Conclusion</title> <p id="abspara0025">The palatal approach is feasible in 93.6% of patients with remnant alveolar height of up to 4 mm. Limitations are alveolar heights of ≤5 mm as well as great palatal thickness and thus limited dimensions for a possible palatal window.</p> </sec> </abstract>
