“…Bone quality and quantity are necessary for a successful implant placement in the upper and lower jaws. However, "con-beam computed tomography" (CBCT) has been widely used for the surgical planning in dental implant treatment, assessment of bone around dental implant, and evaluation of bone "microstructure," and the quantity of bone in both jaws can be evaluated by CBCT through implant treatment [7][8][9].…”

Understanding the quality of the ridge and facial cortical bone in the aesthetic zone is important for treatment with an immediate dental implant. This study aimed to analyze bone density and widths of the facial cortical bone and alveolar ridge at the central incisors in relation to arch form. A total of 400 teeth from 100 cone-beam CT images were divided equally between the upper and lower central incisors. The central incisor area was assessed for the width of the facial cortical and alveolar bones at three different points (3 mm, 6 mm, and 9 mm from the cementoenamel junction). Arch forms and densities of cortical and cancellous bones in the interradicular regions were evaluated. The difference in facial cortical bone thickness at 3 points was smaller for the upper teeth than for the lower teeth on both sides. The alveolar bone width was higher in the maxilla than the mandible with highly significant differences ( P < 0.001 ). The highest bone density was at the buccal aspect of the mandible (897.36 ± 136.72 HU), while the lowest density was at the cancellous bone of the maxilla (600.37 ± 126.63 HU). The dominant arch form was ovoid 71%, followed by square 20% and the tapering arch form 10%. The tapering arch form has the highest alveolar bone width in the upper jaw without statistical significance. The facial cortical bone thickness needs to be evaluated before implantation in the anterior region because it is less than two millimeters in both jaws. CBCT is important for the immediate implant. The ovoid shape was the dominant arch form.

“…The thickness of the jaw and the position of the anatomical landmarks following bone resorption have been examined in a few Iraqi studies. 13–15 Nevertheless, the characteristics of the mandibular symphyseal area in completely edentulous patients have not been extensively examined in the Iraqi population. The goal of this CBCT study was to evaluate certain characteristics of the edentulous mandibular symphyseal area (MS), including bone density, cortical thickness, and bone dimensions.…”

Background Overdentures supported by dental implants are a useful treatment strategy for patients with edentulous mandibles. The aim of this study was to evaluate certain characteristics of the mandibular symphyseal edentulous cases for dental implant treatment using CBCT; and if it is associated with gender differences. Methods Ninety patients (45 females and 45 males) were included in this investigation. A section along the midline of each CBCT image was chosen for the edentulous symphyseal area. Symphysis height, width, and cortical thickness was measured for each patient. Bone density were calculated at four points A two-sample Student’s t -test and Pearson correlation were used for statistical analysis. Results Males had a considerably greater symphysis height (26.66±6.21 mm) than females (24.07±5.00 mm) (p = 0.02). Similar results were found for bone width; males had greater means than females. In case of cortical bone thickness; males had thicker bone cortex in the buccal region than females (p = 0.01). While the difference in bone density between genders was small. However, a positive relationship was recorded between symphysis height and width. Conclusion Height and width of the mandibular symphysis were influenced by gender in edentulous patients, with men showing higher measurements. The reduction of symphyseal height decreased concurrently with the width after teeth were lost, while bone density was maintained in both genders with no difference between them. The lingual cortical bone is significantly thicker than the buccal cortex at the lower part of the symphysis.
