“…Based on Peterson's data, a 3D constitutive law describing the macroscopic mechanical behavior of cortical and trabecular bone was defined [23]. As bone is living tissue, the alteration of its structure over time is very important [24,25,26,27]. Changing stress and strain are crucial factors in the healing process after bone fractures or surgery.…”

2 AbstractPurpose: The aim of the present experimental 3D-finite element study was to evaluate the influence of an augmented sinus lift with an additional inserted bone graft block. The bone graft block stabilizes the implant in addition to conventional augmented bone. We placed the block in three different positions. The implants were loaded with axial force and forces secondary to laterotrusion and protrusion. Material and Methods:A simplified U-shaped 3D finite element model of the upper jaw and a more complex anatomical model of the left maxilla were created. The bone graft block was placed in three positions: in the lower third in contact with the sinus floor, the middle, and the upper third of the implant. Van Mises' stress distribution was calculated and analyzed for the different models. We also compared the complex anatomical model with the simplified one. Results:The position of the bone graft block significantly influences the magnitude of stress distribution. A bone graft block positioned in the upper third or middle of the implant reduces the quantity of stress compared to the reference model without a bone graft block. The low bone graft block position is clearly associated with lower stress distribution in compact bone.We registered no significant differences in stress in compact bone with regard to laterotrusion or protrusion. Conclusions:Maximum values of von Mises stresses in compact bone can be reduced significantly by using a bone graft block. The reduction of stress is nearly the same for positions in the upper third and the middle of the implant. It is much more pronounced when the bone graft block is in the lower third of the implant near the sinus floor, which appeared to be the best position in the present study.

“…Standard non-invasive methods for radiological measurement of augmentation status before and after dental implantation include digital panoramic radiography, computed tomography, and CBCT (Shanbhag et al, 2014;Danesh-Sani et al, 2016). With the ongoing technological improvements in the quality of radiography, more detailed 2D panoramic images have become available.…”

“…However, digital panoramic radiography, computed tomography, and/or cone beam computed tomography (CBCT) can now be used for noninvasive measurement of augmentation status before and after implantation (Shanbhag et al, 2014;Danesh-Sani et al, 2016). The market for CBCT has expanded markedly in recent years (Jacobs and Esposito, 2016).…”

Sinus floor augmentation is an effective method to regain bone height for the successful insertion of dental implants into the posterior maxilla. The aim of the study was to evaluate the behaviour of augmentation material following simultaneous or staged dental implant insertion, as visible on digital panoramic radiographs using the GNU Image Manipulation Program (GIMP). We evaluated one-stage (group 1) or two-stage (group 2) maxillary sinus floor augmentation procedures in 19 patients, using a high temperature-treated bovine porous hydroxyapatite material. Digital panoramic radiographic measurements were captured pre-operatively in both groups, pre-implant insertion in group 2, and immediately postoperatively and 6 months postoperatively in both groups. Forty parallelwalled bone-level implants were placed in a one-stage (n=18) or two-stage (n=22) protocol, with a mean residual bone height of 4.9±1.8 mm and survival rate of 100%. Mean bone height increased by 8.6±1.6 mm immediately post-implantation and by 7.9±1.7 mm after 6 months. Mean distal and mesial bone losses after abutment connection were 0.42±0.24 mm and 0.34±0.27 mm, respectively. No significant intergroup or intragroup differences between simultaneous and staged dental implant procedures were found. Our results show that the histogram tool in GIMP is useful for documentation of the area of the augmentation material used in maxillary sinus floor augmentation.

“…Shanbhag S.et al [7]systematically reviewed the available literature on graft volume changes after sinus augmentation with different biomaterials using three-dimensional images.Seven controlled and five uncontrolled studies (234 sinus lifts) were included and reported on a range of graft materials.Autogenous bone was used in the particulate or block form.Bone substitutes were used either alone or in combination with other materials as composite grafts. All studies reported reductions in bone graft volumes over time, generally after 6 months to 6 years.…”
