This report describes a periodontal tissue regeneration technique for an anterior maxillary intrabony defect, in which salt bone modeling and 3D-CT fusion analysis were performed for preoperative assessment and postoperative evaluation.<br>A 55-year-old male presented with clinical and radiographic evidence of an intrabony defect around the maxillary right central incisor. After the initial periodontal therapy, we prepared salt bone modeling from CT data to evaluate the anatomical form of the bone loss. Periodontal tissue regeneration in combination with alloplast and guided tissue regeneration (GTR) was applied at the site. Six months after the surgery, we conducted 3D-CT fusion analysis.<br>Conventional preoperative assessment via dental X-ray imaging and measurement of probing pocket depth is effective for assessing the 2-dimensional bone resorption level and clinically-defined pocket bottom, however, it has a limitation in assessing the anatomical form of the bone loss. Preoperative assessment employing salt bone modeling in this study enabled us to obtain a 3-dimensional image of the anatomical form. Furthermore, it reduced the operative time since it enabled us to determine the form and size of the GTR membrane. Moreover, postoperative 3D-CT fusion analysis allowed detailed evaluation of the site where bone regeneration was taking place.
