Grow factors such as PRP or BMP-7 in association with autogenous
bone seem to produce a superior outcome regarding bone fraction at 4 months after sinus floor surgery , but no clinical benefits could be observed in a meta-analysis by Rickert et al.
There is limited information regarding bone formation and early stability in autogenous
bone grafts; it is possible that part of the remodeling observed over time is also generated by the times involved, from the time of installation of the graft to its use.
Resorption of Bio-Oss particles was observed at lower levels, while in Ostim and autogenous
bone graft, the process of the active resorption and replacement with NB were seen.
vein and nerve grafts: a comparative study of nerve regeneration in the rat," Journal of Hand Surgery B, vol.
Various bone augmentation techniques have been described in the literature in order to reconstruct deficient alveolar ridges such as particulate bone grafting, guided bone regeneration, autogenous
bone block graft, ridge expansion, and alveolar distraction osteogenesis (McAllister and Haghighat, 2007; Chiapasco et al., 2006 & 2007; Esposito et al., 2006).
The discussion on the effectiveness and efficiency of one or the other type of material has not been completely resolved, since many studies have methodologies that cannot be compared; there is clarity, however, that the increase in width of the alveolar process is positively related to the use of autogenous
bone graft blocks, as these are stabilized with screws using generally compressive techniques (Sakkas et al., 2017).
vaccine administration caused sloughing off the warts from the affected areas.
Thermal Dilation (TD) and Autogenous
Based on the basic theory of chemical shrinkage, autogenous
shrinkage and drying shrinkage of OC, this paper discussed the classification and definition of the early-age shrinkage of the UHPFRC and clarified the main influencing factors of different shrinkage.
It must be remembered that most of the patients reconstructed with an autogenous
graft require at least one additional maxillomandibular surgical procedure due to the high percentage of ankylosis, fracture, variable growth behavior, resorption, infection, and donor side morbity .
Various materials have been tried for brow suspension such as muscle tendon, preserved donor sclera, artificial materials that included catgut or silk sutures, wires of gold, silver or platinum metals, however the most widely used artificial material is polyfilament suture which is easy to handle with lesser incidence of complications.11-14 Brow suspension with autogenous
fascia lata is considered as gold standard procedure for congenital ptosis as it has a long-lasting effect for upper eyelid elevation.
bone is considered the gold standard for implantation because of its biocompatibility and osteogenicity [1, 2].
