“…Platzer et al [11] used a non-commercial measurement technique based on the novel concept of an Interactive Rigid Registration Algorithm (IRRA). Parameters analyzed included the reproducibility of IRRA measurements and their reliability in comparison with the established measurement technique of RGST.…”

“…Nevertheless, resorption and remodeling of an autologous bone graft still remains a concern, as an imbalance between these processes may lead to insufficient bone volume and thereby frustrate implant placement [10]. Volumetric reduction of grafting material has been observed with autogenous bone grafts as well as synthetic bone substitute materials [11][12][13][14][15][16].…”

“…The success of sinus lift augmentation procedures may be evaluated by various criteria, such as whether the quality and density of newly formed bone maintains threedimensional stability and achieves a high percentage of vital bone-to-implant contact [11]. Grafted sinuses may adapt considerably in shape and volume due to repneumatization of maxillary sinuses [12].…”

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.

“…Clinically, a BS should be easy to use, cost effective, and with adequate density to allow easy radiographic recognition during the entire healing process [27, 29]. This feature is particularly important to radiographically follow the rate of resorption/substitution [30, 31]. …”

Bone substitutes used in oral surgery include allografts, xenografts, and synthetic materials that are frequently used to compensate bone loss or to reinforce repaired bone, but little is currently known about their physicochemical characteristics. The aim of this study was to evaluate a number of physical and chemical properties in a variety of granulated mineral-based biomaterials used in dentistry and to compare them with those of autogenous bone. Autogenous bone and eight commercial biomaterials of human, bovine, and synthetic origins were studied by high-resolution X-ray diffraction, atomic absorption spectrometry, and laser diffraction to determine their chemical composition, calcium release concentration, crystallinity, and granulation size. The highest calcium release concentration was 24. 94 mg/g for Puros and the lowest one was 2.83 mg/g for Ingenios β-TCP compared to 20.15 mg/g for natural bone. The range of particles sizes, in terms of median size D50, varied between 1.32 μm for BioOss and 902.41 μm for OsteoSponge, compared to 282.1 μm for natural bone. All samples displayed a similar hexagonal shape as bone, except Ingenios β-TCP, Macrobone, and OsteoSponge, which showed rhomboid and triclinic shapes, respectively. Commercial bone substitutes significantly differ in terms of calcium concentration, particle size, and crystallinity, which may affect their in vivo performance.

“…Moreover, the algorithm developed in this study enabled determining the volume of the grafted area thereby reflecting the anatomical situation present clinically in a reproducible manner. There are a number of in vitro methods available for such volumetric measurements, all of which have a number of drawbacks in that they do not adequately take into account postoperative variability such as tissue responses of the Schneiderian membrane, air entrapment in the grafting material and others [35].…”

This study examines the effect of a hyaluronic acid (HyAc) containing tricalcium phosphate putty scaffold material (TCP-P) and of a particulate tricalcium phosphate (TCP-G) graft on bone formation, volume stability and osteogenic marker expression in biopsies sampled 6 months after bilateral sinus floor augmentation (SFA) in 7 patients applying a split-mouth design. Biopsies were processed for immunohistochemical analysis of resin embedded sections. Sections were stained for collagen type I (Col I), alkaline phosphatase (ALP), osteocalcin (OC) and bone sialoprotein (BSP). Furthermore, the bone area and particle area fraction were determined histomorphometrically. Cone-beam CT data recorded after SFA and 6 month later were used for calculating the graft volume at these two time points. TCP-P displayed more advantageous surgical handling properties and a significantly greater bone area fraction and smaller particle area fraction. This was accompanied by significantly greater expression of Col I and BSP and in osteoblasts and osteoid and a less pronounced reduction in grafting volume with TCP-P. SFA using both types of materials resulted in formation of sufficient bone volume for facilitating stable dental implant placement with all dental implants having been in function without any complications for 6 years. Since TCP-P displayed superior surgical handling properties and greater bone formation than TCP-G, without the Hyac hydrogel matrix having any adverse effect on bone formation or graft volume stability, TCP-P can be regarded as excellent grafting material for SFA in a clinical setting.
