Maxillary sinus graft augmentation using β-TCP is clinically effective.
Analysis by CBCT provides superior spatial resolution and allows for extremely accurate postoperative evaluation of maxillary sinus floor augmentation and bone volume measurements.
On the basis of CBCT examinations, although maxillary sinus pneumatization continues to progress ≥1 year after surgery, it stabilizes 3 year...
During the observation period, there was no clinical implant failure and the suvival rate for implantation and maxillary sinus floor augmentation was 100 %. Histological examination in a previous report on maxillary sinus augmentation using β-TCP (Cerasorb®), Szabo et al. compared bilateral maxillary sinus augmentation in the same patients using β-TCP and iliac bone at 6 months after surgery ...
As grafting materials for maxillary sinus floor augmentation, autogenous bone, which is considered as the gold standard and reported first by Boyne et al. using iliac bone graft, has been used as the first-choice material. In terms of osteogenic, osteoinductive, and osteoconductive properties, autogenous bone is considered ideal; however, the use of autogenous bone places great physical stress on ...
Change in height of bone surrounding the implant (height from the maxillary sinus floor to the implant tip): Immediately after surgery, all patients had grafted bone between the implant tip and the maxillary sinus floor, with a mean of 2.00 ± 1.51 mm. This height decreased to 0.73 ± 1.33 mm at 6 months after surgery and −0.72 ± 1.11 mm at 2.5 years after surgery (Fig. 5). 41...
The mean age of the 30 patients was 57.4 (40–75) years, and the male/female ratio was 4:26. The mean postoperative observation period was 3 years and 8 months (the maximum period was 5 years and 0 months; the minimum period was 2 years and 2 months). Total of 58 implants were placed at premolar and molar region. There were no dropouts, such as participants not visiting the clinic, during t...

In the present study, we used the superior spatial resolution of CBCT to measure changes over time in (a) the volume of the bone graft (BV) and (b) the height of the bone surrounding the implant (BH).
The method of calculating the volume of the implant site is shown below (Fig. 2).
The slice thickness (voxel value) was resized (0.146 mm → 1 mm) to derive the volume of the grafting agent...
This study is a prospective observational study. The subjects included patients who had undergone maxillary sinus floor augmentation using β-TCP and implant placement at the Clinic for Implant Dentistry, Dental Hospital, Tokyo Medical and Dental University during the 3-year period from January 2009 to December 2011. All patients underwent maxillary sinus floor augmentation at the same time as imp...
Radiographic examinations to determine changes in bone mass in maxillary sinus floor augmentation have been conducted primarily using panoramic radiography [8–12], which allows for the assessment of the height of the maxillary sinus in only two dimensions. In addition, it does not allow for detailed examination or measurement of the interior of the maxillary sinus without factoring in magnificat...
The maxillary sinus gradually expands after birth and becomes fully pneumatized with the eruption of all permanent teeth. Although the physiological cause and maxillary sinus pneumatization are largely unknown, it is believed that genetics, atmospheric pressure, and hormones are involved in it. This sinus is closely related to the root apex of the premolar and molar teeth, and it is either separat...
The 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).
The subjects included 30 patients who underwent maxillary sinus floor augmentation using β-TCP and 58 implant placement for unilateral maxillary defect...

The present study showed that maxillary sinus floor augmentation with BC resulted in adequate amounts of new bone formation allowing successful implant installation, while adding EMD did not have a significant effect.
Nevertheless, the amount of bone generated with BC or BC + EMD herein was adequate to support successful implant placement and osseointegration of implants. In fact, more or less similar amounts of bone formation have been reported in studies evaluating human sinus biopsies after grafting with a variety of biomaterials (bone formation ranging approximately from 30 to 50%) [19]. On the other ha...
The present study compared the histological and histomorphometrical outcome of healing after maxillary sinus floor augmentation with BC with or without EMD, based on human biopsies. The results showed that addition of EMD did not enhance the outcome of healing, neither in terms of quality nor quantity of new bone. Nevertheless, the amount of bone generated after maxillary sinus floor augmentation ...
All ten patients showed uneventful healing after the sinus floor augmentation procedure as well as after dental implant placement, with no overt postoperative inflammation or infection. Consistently, in all ten patients, no significant jiggling of the drill was noticed during biopsy harvesting, while subjective drilling resistance during implant placement was similar in both groups and all implant...

The aim of the present study was to compare histomorphometrically the outcome of maxillary sinus floor augmentation with β-TCP/HA with or without enamel matrix proteins (BC + EMD and EMD, respectively) in humans.
Reconstruction of the edentulous and severely atrophied posterior maxilla is often performed by means of maxillary sinus floor augmentation in combination with dental implants [1, 2]. Various bone graft materials are typically used for enhancing bone formation within the sinus cavity; autogenous bone (AB) is considered as the gold standard due to its osteogenic, osteoinductive, and osteoconductive...
It is still unclear whether enamel matrix proteins (EMD) as adjunct to bone grafting enhance bone healing. This study compared histomorphometrically maxillary sinus floor augmentation (MSFA) with β-TCP/HA in combination with or without EMD in humans.
