“…Radiographic evaluations of vertical graft height after maxillary sinus floor elevation are well documented [8,9,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. However, these studies differ in radiographic methods, using panoramic radiographs [18, 22-24, 29, 33], computed tomography (CT) [9,21,23,26] or cone beam computed tomography (CBCT) [8,22,32,34].…”

Aim The aim of this retrospective study was to quantify three-dimensional (3D) volumetric bone changes over a two-year period in maxillary sinuses augmented with a mineralized cortical bone allograft material (MCBA) material. Patients and Methods Eleven patients (6 males and 5 females) with mean of age of 51.6 (range: 46-61) years were treated to increase the vertical dimension of the alveolar crest by maxillary sinus floor augmentation procedure. Study data were collected from patient records and by analyzing preoperative radiographs and cone beam computed tomography (CBCT) scans taken within the first two weeks after maxillary sinus lift (T0), immediately before implant placement four months after grafting (T1), and after one year of implant loading (T2). All DICOMformatted images were rendered into volumetric images using software that automatically calculated the volume of the grafted material in cubic centimeters. Results Mean graft volume was 16.24 ± 1.54 cm 3 at T0, 14.48 ± 1.48 cm 3 at T1 and 13.06 ± 1.39 cm 3 at T2. Mean volume retraction resulted in 1.76 ± 0.34 cm 3 DV1 (T0-T1) and 1.42 ± 0.4 cm 3 DV2 (T1-T2) and was 10.83 % of the initial total volume at (T0-T1) and 9.8 % of the total volume (T1-T2). Conclusion The present retrospective investigation demonstrated a 20.63 % decrease in graft volume. Volumetric 3D assessment of CBCT scans with the selected software appeared to be a promising approach to quantifying longterm changes in the grafted area.

“…An increasing number of clinical studies using CBCT to follow graft volume changes have demonstrated the potential for applying this technique to assess not only the quantity but also the quality of the osseointegrated graft. [13][14][15][16] And it has recently been reported to be the best clinically available tool for assessing graft volume changes in vivo. 17 CBCT was additionally found to be equally valid to multislice CT in following up osseous volumetric changes in a cleft palate model.…”

Objectives: Maxillary sinus augmentation is a well-documented procedure with long-term success in implant dentistry. Assessing graft volume changes over time is crucial, since resorption remains a major concern. CBCT is commonly employed to assess the quantity and quality of the available bone at the implant receptor site. However, its applicability in following graft volume changes is yet to be determined. The study aimed to assess CBCT accuracy in following simulated graft resorption ex vivo. Methods: 4 differently sized autogenous bone blocks harvested from the zygomatic buttress were bilaterally placed in the maxillary sinus of 12 human cadavers. The Accuitomo (J Morita, Kyoto, Japan) CBCT system was employed to scan each one of the 4 grafts in each of the 12 cadavers using identical settings. Gold standard graft measurements were obtained using micro-CT. One independent observer assessed the volume of each graft on CBCT images twice. Intraobserver reliability was assessed using Cohen's kappa and one-sample t-test was used to compare CBCT with micro-CT volumetric measurements. Results: The mean micro-CT graft volumes were 97.12 ± 1.4, 197.32 ± 3.4, 361.41 ± 4.2 and 1040.11 ± 3.2 mm 3 for Grafts 1-4, respectively, and the mean CBCT volumes of the corresponding grafts were 115. 39 ± 7.01, 205.97 ± 9.91, 404.05 ± 16.81 and 1138.04 ± 20.98 mm 3 . CBCT measurements were statistically significantly different from micro-CT measurements (p 5 0.001). Intraobserver reliability was good (r 5 0.78). Conclusions: In every case, CBCT overestimated the maxillary graft volume in comparison with micro-CT. However, the measurement differences were limited and might not influence clinical performance.
