Three dimensional (3D) printing allows additive manufacturing of patient specific scaffolds with varying pore size and geometry. Such porous scaffolds, made of 3D-printable bone-like calcium phosphate cement (CPC), are suitable for bone augmentation due to their benefit for osteogenesis. Their pores allow blood-, bone- and stem cells to migrate, colonize and finally integrate into the adjacent tissue. Furthermore, the pore size affects the scaffold’s stability. Since scaffolds in maxillofacial surgery have to withstand high forces within the jaw, adequate mechanical properties are of high clinical importance. Although many studies have investigated CPC for bone augmentation, the ideal porosity for specific indications has not been defined yet. We investigated 3D printed CPC cubes with increasing pore sizes and different printing orientations regarding cell migration and mechanical properties in comparison to commercially available bone substitutes. Furthermore, by investigating clinical cases, the scaffolds’ designs were adapted to resemble the in vivo conditions as accurately as possible. Our findings suggest that the pore size of CPC scaffolds for bone augmentation in maxillofacial surgery necessarily needs to be adapted to the surgical site. Scaffolds for sites that are not exposed to high forces, such as the sinus floor, should be printed with a pore size of 750 µm to benefit from enhanced cell infiltration. In contrast, for areas exposed to high pressures, such as the lateral mandible, scaffolds should be manufactured with a pore size of 490 µm to guarantee adequate cell migration and in order to withstand the high forces during the chewing process.

Background: Tooth extraction is a common procedure in dentistry after which the residual ridge will no longer receive stimulus leading to volume, height and width loss. These anatomical changes can then result in difficulties with future denture fabrication and implant placement. Preservation of the alveolar ridge, therefore, assumes considerable importance after tooth extraction. Moringa oleifera, on the other hand, can enhance bone formation. Type-1 collagen is a marker of osteoblast formation. Purpose: This research aimed to analyze the effects of Moringa oleifera leaf extract combined with DFBBX on type-1 collagen expressions in tooth extraction sockets. Methods: 56 Cavia cobaya subjects were divided into eight groups. Their lower left incisors were then extracted prior to the sockets of the first and fifth groups being filled with PEG, those of the second and sixth groups with DFBBX, those of the third and seventh groups with Moringa oleifera leaf extract and a combination of DFBBX and Moringa oleifera leaf extract in those of the fourth and eighth groups. The sockets were then examined on days 7 and 30 by means of an immunohistochemical technique. The data collected was subsequently subjected to analysis by One Way Anova and Tukey HSD tests. Results: There were significant differences between the control group and the treatment group administrated with Moringa oleifera leaf extract combined with DFBBX. On days 7 and 30, the groups treated with the combination of DFBBX and Moringa oleifera leaf extract had the highest number of type-1 collagen expressions. Conclusion: A combination of DFBBX and Moringa oleifera leaf extract is effective in increasing type-1 collagen expressions in tooth extraction sockets.

“…7 Reconstruction of osseous defects was first approached in 1923 by Hegedus using bone grafts. 8 The approach was furtherly reported and performed in 1965 by Nabers and O'Leary. 9 due to their osteogenic properties, it has been indicated that autografts are considered the gold standard modalities in the field when compared to other modalities.…”

Using bone grafts has been described in the literature for multiple decades and has been applied within the different medical fields. Furthermore, in the field of dentistry, evidence shows that these approaches have been widely used for different purposes, including the management of craniofacial defects and dental implantology. However, it should be noted that many disadvantages have been reported for the different tissue sources of bone grafting in dental implants despite the wide acceptance of the outcomes and favorable prognosis with these materials. Therefore, many efforts were conducted to innovate further approaches with reduced disadvantages and favorable outcomes. Our present study discusses the types and tissue sources of bone grafts in the settings of dental implants. This can provide dentists with better information and enhanced knowledge levels about the tissue sources of dental implants, which should help them decide the most appropriate source with the least adverse events. Different tissue sources were reported in the literature, including materials that are no longer used for their disadvantages and associated complications. Among the proposed materials, biomimetics has been reported with favorable outcomes and reduced adverse events, and using combinations of these materials can furtherly enhance the prognosis. Further research is needed to innovate additional modalities that can overcome the currently reported limitations.
