“…In the past, evaluations during implant treatment were primarily performed using panoramic radiography and conventional CT. Recently, however, the use of preoperative and postoperative CBCT has gained popularity, and radiographic assessment by CBCT for volumetric changes in graft bone in maxillary sinus floor augmentation has also been reported [16]. According to our radiographic analysis by CBCT of dental implantation using β-TCP in the present study, we found that the graft volume decreased over time, both at 6 months after surgery and even at 2.5 years after surgery.…”

BackgroundThe long-term stability of maxillary sinus floor augmentation with β-TCP remains largely unknown. We report the long-term assessment of volumetric changes in maxillary sinus floor augmentation with β-TCP by cone-beam computed tomography (CBCT).MethodsThe subjects included 30 patients who underwent maxillary sinus floor augmentation using β-TCP and 58 implant placement for unilateral maxillary defect, simultaneously. Volumetric changes in β-TCP and the height of peri-implant bone were analyzed by CBCT.ResultsIn all patients, the mean volume of the grafted bone decreased from immediately after implant placement to 6 months after implant placement (75.6 % reduction rate); it decreased further at 2.5 years after implant placement (54.9 % reduction rate). The mean of the height from the implant tip to the maxillary sinus floor was 2.00 ± 1.51 mm, 0.73 ± 1.33 mm, and −0.72 ± 1.11 mm immediately, 6 months, and 2.5 years after implant placement, respectively. The implant tip protruded beyond the maxillary sinus floor in approximately 70 % of the implants (41/58 implants) at 2.5 years after surgery. During the observation period, the implant survival rate was 100 %.ConclusionsThe radiographic analysis by CBCT is considerably more advanced than previous radiographic examinations. Although maxillary sinus pneumatization continues to progress ≥1 year after maxillary sinus floor augmentation with β-TCP, it stabilizes 3 years after surgery.

“…Umanjec-Korac S. et al [14] analyzed the resorption rate of deproteinized bovine bone material used alone as well as mixed with autologous bone chipsas graft material. A retrospective analysis of 29 augmented sinuses in 19 patients was conducted and CBCT scans of the augmented sinuses were obtained pre-and post-operatively up to 2-year followup.The results indicatedsimilar graft volume resorption for both groups of approximately 20 ± 10%.…”

“…4 For such cases, sinus lifting procedure is employed frequently in the dental practice with high predictability and well surgical outcomes. 5 Maxillary sinus lifting procedure has become widely accepted as a routine method to improve the bone height before implant placement. [6][7][8] Several sinus floor elevation techniques have been recommended in the literature to overcome these limitations.…”

Abstract:Aim: The aim of this study was to evaluate retrospectively the clinical outcomes of laterally approached sinus floor lifting with xenografts and simultaneously dental implant placement procedures. Material and methods:All patients treated with sinus lifting and simultaneous implant placement procedure and were followed for at least 1 year were retrospectively selected for this study. The lateral window technique was performed using a xenogeneic corticocancellous grafting material and submerged implants were placed immediately. Survival rates of implants and clinical features of patients and implants were evaluated.Results : A sample of 30 patients, 42 implants were placed according to the one-stage approach. Residual preoperatively alveolar ridge height varied between 3 and 6 mm with a mean of 4.58 mm and the bone gain at 1-year follow-up varied between 6 mm and 10 mm with a mean of 8.6 mm. Only two implants were lost before loading and overall survival rate was 96% for the implant-based analysis. Conclusions:Maxillary sinus lifting procedure with xenogeneic cortico-cancellous graft material and simultaneously implant placement was showed as a predictable and successful treatment modality.

A retrospective analysis of the resorption rate of deproteinized bovine bone as maxillary sinus graft material on cone beam computed tomography

Abstract: The results indicate that DBB graft volume resorption is approximately (20 ± 10%) following 2-year follow-up. CBCT is a useful radiographic tool to follow-up changes in sinus graft volumes.
