The traditional rhytidectomy addresses facial and neck aging as it relates to soft tissue laxity. The modern volumetric facelift provides optimal results by addressing not only skin laxity but also the loss of volume secondary to tissue atrophy and bony resorption. While multiple techniques including fat grafting, dermal fillers, and tissue resuspension are used to correct the tissue loss, alloplastic midface augmentation remains the most permanent method.

Titanium and its alloys have been widely used as orthopedic and dental implants for several decades due to their superior mechanical properties, corrosion resistance and biocompatibility. Recently, many researches revealed that the hydroxyapatite coatings on biomedical materials can further improve their biocompatibility and bioactivity. However, hydroxyapatite coatings are easily decomposed, weakening the bonding between implants and bone tissues and resulting in a high dissolution rate in the biological environment. Read More

In this study, we investigated the effect of the two flavonoids, baicalin (baicalein 7-O-[Formula: see text]- d-glucuronic acid) and its aglycone, baicalein (5,6,7-trihydroxyflavone), after encapsulation into amorphous calcium polyphosphate (Ca-polyP) microparticles on mineralization of primary human osteoblasts (phOSB). Both flavonoids, which come from root extracts of Scutellaria baicalensis Georgi, are used in Traditional Chinese Medicine, and are nontoxic in cells up to a concentration of 3[Formula: see text][Formula: see text]g/ml. The morphogenetically active, energy-rich Ca-polyP particles with a stoichiometric P:Ca ratio of 1:2 are degraded by cellular alkaline phosphatase (ALP) to ortho-phosphate used for bone hydroxyapatite formation.

Allogenic implants are an effective alternative to autologous grafts in the reconstruction of facial defects. These implants are used to reconstruct a variety of bony and soft-tissue defects, including the frontal and temporal regions; internal orbit; infraorbital rim; malar, paranasal, and nasal regions; mandible; and chin. In comparison to their autologous counterparts, alloplastic materials are more readily available, lack donor-site morbidity, decrease surgical time and cost, and still have relatively good postoperative tissue tolerance.
