Augmentation procedures like sinus lifts are often needed to address insufficient bone volume. This study aims to explore if alveolar ridge preservation, using a bovine bone substitute and a porcine collagen membrane, significantly decreases the need for sinus lifts compared to natural wound healing after tooth extraction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>In this comparative clinical study, 40 patients requiring a total of 53 extractions were assigned to one of the following groups: a test group with bovine bone substitute material (Straumann\u00ae XenoFlex) and a porcine collagen membrane (Jason\u00ae membrane), or a control group with spontaneous socket healing. After 6\u2009months, digital volume tomography was performed for implant planning.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For seven patients from the control group (<jats:italic>n<\/jats:italic>\u2009=\u200922 extracted sites) sinus lift augmentations were performed while only four sinus lift procedures were performed in the test group (<jats:italic>n<\/jats:italic>\u2009=\u200931 extracted sites), indicating a higher need for sinus augmentation procedures in the control group, however not statistically different on a <jats:italic>p<\/jats:italic> value of 0.05 (<jats:italic>p<\/jats:italic>\u2009=\u20090.168). In the control group, the mean value of the radiographically measured bone height (mesial and distal) was 11.13\u2009\u00b1\u20092.12\u2009mm preoperatively before tooth extraction, while it was 11.3\u2009\u00b1\u20092.17\u2009mm postoperatively after implant placement. In contrast, the mean value in the test group was 11.78\u2009\u00b1\u20093.09\u2009mm preoperatively and 11.92\u2009\u00b1\u20092.79\u2009mm postoperatively. Statistical analysis revealed no significant difference between the two groups (odds ratio 0.32; 95% CI: 0.08, 1.26; <jats:italic>p<\/jats:italic>\u2009=\u20090.951).

Additionally, the Alveolar Ridge Preservation in the test group made external sinus floor elevation unnecessary compared to the control group. The change in radiographically measured bone height pre\u2010 and postoperatively showed no significant difference between the two
