“…A mean volume reduction of 8.14% could be noticed after 6 months. Similar results were reported in a prospective case series in 18 patients by Mazzocco et al Using CBCT images taken within the first hour after sinus lifting and after 8 months, a significant decrease of 9.8% was demonstrated. Interestingly, two cases presented an increase in augmentation volume.…”

“…Numerous studies have been published on bone graft stability based on two‐dimensional imaging techniques, demonstrating a significant decrease in augmented bone height within 6‐24 months after sinus lifting . Studies have also been reported on the three‐dimensional (3D) volume stability of these grafts . Although being numerous, these studies differ substantially regarding follow‐up time, method of evaluation, bone graft material, and surgical procedures.…”

Background A sinus floor augmentation may be indicated when a lack of hard tissue impedes implant placement. Although clinically successful, evidence supporting the long‐term three‐dimensional stability of the grafted volume is scarce. Second, evidence on the patient's acceptance of this type of treatment is limited. Purpose First is to evaluate the changes in graft volume after lateral wall sinus lifting based on superimposed cone beam computed tomography (CBCT) images and then to assess patient‐reported outcome measures (PROMs) and clinical outcomes. Materials and Methods Partially edentulous patients in need of a sinus lift and fixed reconstruction on at least two neighboring implants were selected for a prospective case series. Lateral wall sinus augmentation was performed using deproteinized bovine bone mineral (DBBM) as the only filling material. Volumetric changes were quantified on the basis of a preoperative CBCT and three postoperative CBCTs (at 2 weeks, 3 months, and 2 years). PROMs and clinical parameters were registered. Results Twenty‐two patients (7 males, 15 females; mean age 59 years) participated of which three patients dropped out during the follow up. Graft volumes amounted to 1418.26 mm3 at 2 weeks, 1201.21 mm3 at 3 months, and 1130.13 mm3 at 2 years postoperative pointing to a relative graft volume stability of 79.7%. Swelling was the leading symptom during the first week. A peak in visual analogue scale scores was observed for pain, swelling, and hematoma the day of surgery and 1 day postoperation with a statistically significant decline between days 3 and 7. Hemorrhage and nose bleeding occurred in 18.2% and 27.3% of the subjects, respectively. About 95.5% of the subjects would undergo the treatment again. All implants integrated successfully and demonstrated healthy clinical conditions. Conclusion Lateral wall sinus augmentation using DBBM as the only filling material is a viable treatment concept given limited graft resorption, good patients' tolerance, and clinical outcomes.

“…[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. 18 The study was limited as just one type of CBCT scanner was used; therefore, findings could be different with other CBCT systems.…”

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.
