“…The mean HD was 4.5 mm, and the mean CT was 2.3 mm in a study by Lee et al, which increased towards the posterior teeth [ 20 ]. The average HD reported by Zeltner et al, [ 21 ] and Ataman et al [ 22 ] was 10.27 ± 2.1 mm and 8.38 ± 2.66 mm, respectively. However, the measurement of the horizontal dimension of bone block was different in their studies.…”

“…Lee et al studied 20 patients with normal occlusion and reported a mean ID of 53.1 ± 3.6 mm [20]. Zeltner et al, [21] and Ataman et al [22] measured the length of harvestable bone, considering a safe margin of 5 mm away from the mental foramen. Zeltner et al [21] reported an average ID of 37.46 ± 3.84 mm, and a higher VD vertical dimension, HD horizontal dimension, CT cortical thickness, C/C cortical bone to cancellous bone ratio; M median, IQR interquartile range Fig.…”

“…Zeltner et al [ 21 ] reported an average ID of 37.46 ± 3.84 mm, and a higher ID value was found in individuals with no missing of molars. Ataman et al [ 22 ] evaluated various intraoral donor sites and concluded that the volume and density of the symphyseal bone were higher than the ramus, palatal and maxillary tuberosity bone blocks. They reported a safe harvestable bone length of 29.76 ± 7.17 mm.…”

“…Considering the safe distance of 5 mm and the recommendations regarding 9.9 mm height for bone harvesting, a VD of 19.9 mm would be required, which is consistent with a median VD of 20.21 ± 3.26 found in the present study. Zeltner et al [ 21 ] and Ataman et al [ 22 ] considered a safe distance of 5 mm from the tooth apex and 2 mm from the inferior cortex of the mandible. They reported lower VD values (12.71 ± 3.25 mm and 13.36 ± 3.71 mm, respectively).…”

Background Bone volume plays a pivotal role in the success of dental implant treatment. Autogenous bone grafts should be harvested from reliable sites in the maxillofacial region. This study sought to assess the quantity and quality of bone in the mandibular symphysis for autogenous bone graft harvesting using cone-beam computed tomography (CBCT). Methods This cross-sectional study evaluated the CBCT scans of 78 adults presenting to three oral and maxillofacial radiology centers. The vertical (VD) and horizontal (HD) alveolar bone dimensions, cortical thickness (CT), and cancellous to cortical bone ratio (C/C) were measured in the interforaminal region of the mandible at the sites of central incisor to first premolar teeth. The interforaminal distance (ID) and the anterior loop length were also measured. Nonparametric statistical tests were used to analyze the data with respect to sex, age, and tooth position. Results The median VD, HD, and CT of the symphysis were 20.21 (3.26), 4.13 (0.37), and 2.25 (0.23) mm, respectively. The median C/C was 1.51 (0.11). The median ID was 52.24 (8.24) mm, and the median anterior loop length was 1.82 (1.06) mm. Significant differences were observed in all parameters among different teeth. Most of the measured parameters were greater in males compared with females. There were significant differences in ID, VD, and CT between different age groups. Conclusions The quantity and quality of the available bone in the mandibular symphysis for bone graft harvesting vary by gender, age, and harvesting site, necessitating careful preoperative evaluation.

“…16 The selection and evaluation of an ideal donor site is an important prerequisite, and has already been described by various authors using three-dimensional radiological techniques (CBCT and computed tomography, CT). [17][18][19][20] In this study, we examined the possibility of using routine two-dimensional dental radiographs to acquire information about the bone supply of commonly used intraoral bone donor regions prior of therapy planning, which can be used during initial consultation.…”

Background: To test the hypothesis that cephalometric parameters in two-dimensional routine dental radiographs correlate with the bone supply of intraoral donor regions. Methods: A total of 108 radiographs (36 panoramic radiographs [PRs], 36 lateral cephalometric radiographs [LCRs], and 36 cone-beam computed tomography scans [CBCT]) of 36 patients were analysed. Cephalometric parameters (PR and LCR) were correlated with the bone supply measurement in three-dimensional CBCT scans in three different intraoral donor regions (chin, mandibular retromolar region, and zygomatic alveolar crest). Results: Different mean bone volumes were measured for the chin (3.10 ± 1.11 cm³ SD), the mandibular retromolar region (1.66 ± 0.54 cm³ SD), and the zygomatic alveolar crest (0.17 ± 0.04 cm³ SD). Cephalometric parameters were significantly correlated with the bone dimensions in the chin and the mandibular retromolar region (all p-values < 0.05). Bone volume of the zygomatic alveolar crest exhibited no correlations with cephalometric parameters but significantly correlated with the mandibular retromolar bone volume (p < 0.01). No gender-specific differences were observed with respect to bone volumes in all bone harvesting regions. However, the interforaminal distance in the chin region was significantly higher in the male population (p = 0.001). Conclusion: Routine 2D radiographs can be used during the initial consultation for primary intraoral bone donor site evaluation. This is anticipated to be helpful in defining indications and justifying further diagnostic options such as three-dimensional radiological techniques.
