“…Numerous studies have been published on bone graft stability based on two‐dimensional imaging techniques, demonstrating a significant decrease in augmented bone height within 6‐24 months after sinus lifting . Studies have also been reported on the three‐dimensional (3D) volume stability of these grafts . Although being numerous, these studies differ substantially regarding follow‐up time, method of evaluation, bone graft material, and surgical procedures.…”

“…The use of autogenous bone (AB) is still considered the gold standard in bone grafting due to its superior biological advantages such as osteogenic, osteoconductive, and osteoinductive properties . However, high resorption rates up to 84% and the need for a second surgical site associated with patient morbidity required to be acknowledged . To compensate for these limitations, biomaterials have been introduced.…”

Background A sinus floor augmentation may be indicated when a lack of hard tissue impedes implant placement. Although clinically successful, evidence supporting the long‐term three‐dimensional stability of the grafted volume is scarce. Second, evidence on the patient's acceptance of this type of treatment is limited. Purpose First is to evaluate the changes in graft volume after lateral wall sinus lifting based on superimposed cone beam computed tomography (CBCT) images and then to assess patient‐reported outcome measures (PROMs) and clinical outcomes. Materials and Methods Partially edentulous patients in need of a sinus lift and fixed reconstruction on at least two neighboring implants were selected for a prospective case series. Lateral wall sinus augmentation was performed using deproteinized bovine bone mineral (DBBM) as the only filling material. Volumetric changes were quantified on the basis of a preoperative CBCT and three postoperative CBCTs (at 2 weeks, 3 months, and 2 years). PROMs and clinical parameters were registered. Results Twenty‐two patients (7 males, 15 females; mean age 59 years) participated of which three patients dropped out during the follow up. Graft volumes amounted to 1418.26 mm3 at 2 weeks, 1201.21 mm3 at 3 months, and 1130.13 mm3 at 2 years postoperative pointing to a relative graft volume stability of 79.7%. Swelling was the leading symptom during the first week. A peak in visual analogue scale scores was observed for pain, swelling, and hematoma the day of surgery and 1 day postoperation with a statistically significant decline between days 3 and 7. Hemorrhage and nose bleeding occurred in 18.2% and 27.3% of the subjects, respectively. About 95.5% of the subjects would undergo the treatment again. All implants integrated successfully and demonstrated healthy clinical conditions. Conclusion Lateral wall sinus augmentation using DBBM as the only filling material is a viable treatment concept given limited graft resorption, good patients' tolerance, and clinical outcomes.

“…Although autogenous bone is regarded as the gold standard, autogenous bone grafts can also exhibit unpredictable bone resorption, which may not be a desirable characteristic in sinus grafting. Indeed the practice of augmented sinuses using autogenous bone as the sole grafting material has been shown to undergo significant re-pneumatization and augmented volume loss according to several clinical reports found in the literature [13,14,15,16], which has led to searches for alternative graft materials. Therefore, the goal is to seek an ideal scaffold that provides good mechanical support temporarily while maintaining bioactivity, and which can biodegrade later at a tailorable rate [17].…”

Some studies have demonstrated that in vivo degradation processes are influenced by the material’s physico-chemical properties. The present study compares two hydroxyapatites manufactured on an industrial scale, deproteinized at low and high temperatures, and how physico-chemical properties can influence the mineral degradation process of material performance in bone biopsies retrieved six months after maxillary sinus augmentation. Residual biomaterial particles were examined by field scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) to determine the composition and degree of degradation of the bone graft substitute material. According to the EDX analysis, the Ca/P ratio significantly lowered in the residual biomaterial (1.08 ± 0.32) compared to the initial composition (2.22 ± 0.08) for the low-temperature sintered group, which also presented high porosity, low crystallinity, low density, a large surface area, poor stability, and a high resorption rate compared to the high-temperature sintered material. This demonstrates that variations in the physico-chemical properties of bone substitute material clearly influence the degradation process. Further studies are needed to determine whether the resorption of deproteinized bone particles proceeds slowly enough to allow sufficient time for bone maturation to occur.

“…If bone loss is significant, intraoral facial prosthetics are the only realistic option for recovering the facial profile and some degree of oral function, such as speaking, mastication and swallowing. Autogenous bone is the gold-standard material for such reconstruction because it has a high inherent physiological capacity for bone formation and demonstrates similar mechanical properties to those of the excised bone [1][2][3][4][5][6][7] , but also carries the risk of extensive bone resorption at the donor site 6) . A heterograft may be used as an alternative, but is itself complicated by the possibility of cross-infection 8,9) .…”

Tri-calcium phosphate (ß-TCP) can be artificially synthesized by recycling dihydrate gypsum hardened

et al. 2014

Calcium phosphate is known as a major component of biological hard tissues. This study aimed to produce calcium phosphate by recycling kneaded surplus gypsum. β-dihydrate gypsum was derived from commercial dental β-hemihydrate gypsum, which was mechanically powdered and mixed with the liquid component of a commercial zinc phosphate cement. This mixture was fired at 1,200°C and evaluated by XRD analysis, thermal analysis and scanning electron microscopy (SEM). An acceptable ratio of mixing was 4 g of β-dihydrate gypsum powder to 1.5 mL of phosphoric acid liquid. XRD peaks were monotonic below 800°C, but new ß-TCP was formed by firing at 900°C or more, although TG-DTA analysis of synthetic ß-TCP suggested that some residual dihydrate gypsum remained in the sample. SEM images indicated a fused-block bone-like structure covered with phosphorus and calcium. These results suggest that production of synthetic β-TCP is possible through ecological techniques using recycled materials.
