Abstract

<abstract abstract-type="main" xml:lang="en" id="clr2431-abs-0001"> <title>Abstract</title> <sec id="clr2431-sec-0001" sec-type="section"> <title>Objective</title> <p>This investigation focused on a comparison of clinical and histological characteristics after sinus floor augmentation with biphasic calcium phosphate (BCP, Straumann BoneCeramic<sup>®</sup>), anorganic bovine bone (ABB, Geistlich Bio‐Oss<sup>®</sup>), mineralized cancellous bone allograft (MCBA, Zimmer Puros<sup>®</sup>), or autologous bone (AB).</p> </sec> <sec id="clr2431-sec-0002" sec-type="section"> <title>Materials and methods</title> <p>Thirty consecutive patients with a posterior edentulous maxillary situation and a vertical bone height less than or equal to 4 mm were included in this study. A two‐stage procedure was carried out. After augmentation of the maxillary sinus with ABB, BCP, MCBA, or AB followed by a healing period of 5 months, biopsies were taken with simultaneous implant placement. The samples were analyzed using microradiography and histology.</p> </sec> <sec id="clr2431-sec-0003" sec-type="section"> <title>Results</title> <p>Ninety‐four implants were placed in the augmented positions and 53 bone biopsies were taken and evaluated. The bone volume fraction of newly formed bone was measured as 30.28 ± 2.16% for BCP, 24.9 ± 5.67% for ABB, 41.74 ± 2.1% for AB, and 35.41 ± 2.78% for MCBA with significant increases in bone volume of AB vs. BCP and ABB, and MCBA vs. ABB samples. Significantly different residual bone substitute material was measured as 15.8 ± 2.1% in the BCP group and 21.36 ± 4.83% in the ABB group.</p> </sec> <sec id="clr2431-sec-0004" sec-type="section"> <title>Conclusion</title> <p>As it provides the highest rate of <italic>de novo</italic> bone formation, AB can be considered to remain the gold standard in sinus floor augmentation. All tested control materials showed comparable results and are suitable for maxillary sinus augmentation.</p> </sec> </abstract>
