Walter C, Dagassan-Berndt DC, Kühl S, Weiger R, Lang NP, Zitzmann NU. Clin Oral Implants Res. 2013 Oct 21. Aim: The aim of this pilot study was to analyze the interfurcal bone height in relation to the possible need for subsequent sinus loor elevation in patients with advanced periodontitis and furcation involvement of irst and / or second maxillary molars. Material and Methods: Seventeen dentate patients, who received cone beam computed tomography (CBCT) for detailed preoperative diagnosis and planning of surgical interventions at periodontally involved maxillary molars (17 irst and 15 second molars), were consecutively recruited for the study. The minimal bone height in the interfurcal region was measured from CBCT and related to furcation involvement, residual bone above the root tips, and the clinical probing pocket depth (PPD). Results: The minimal interfurcal bone height measured 4.1 ± 2.6 mm on average with 75% of maxillary molars having ≤ 6 mm and almost 60% having only ≤ 4 mm bone height left below the sinus loor. A higher risk for reduced interfurcal bone height of ≤ 4 mm was given when residual PPD of ≥ 6 mm was remaining at two or more tooth sites (OR 0.10; 0.11)
