RESULTS: Hundred and sixteen pre-and post-operative 3D photo data sets were included. The sample included 29 subjects. The facial volume was analyzed both overall and comparing each subgroup (orthognathic versus orthognathic + fat grafting group). Post-operative facial volume increase averaged 23.7% for the entire cohort (FG and nFG). By week twelve, the swelling decreased about 62% from baseli...

We present a method for fabricating polymer brushes with a gradual variation of grafting density on solid substrates. The technique for generating such structures consists of: i) deposition of a molecular gradient of polymerization initiator on the solid substrate, and ii) polymerization from the substrate bound initiator centers (“grafting from”). In this publication we describe the preparatio...

Methyl acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, TGA methods. Evidence of grafting was confirmed by FTIR spectroscopy. The morphology evaluated by SEM. The thermal analysis indicated t...

This paper extends recent work on decision tree grafting. Grafting is an inductive process that adds nodes to inferred decision trees. This process is demonstrated to frequently improve predictive accuracy. Superficial analysis might suggest that decision tree grafting is the direct reverse of pruning. To the contrary, it is argued that the two processes are complementary. This is because, like...

We reviewed retrospectively the outcome of the treatment by impaction grafting of periprosthetic femoral fractures around loose stems in 106 patients with Vancouver type-B2 and type-B3 fractures. Eighty-nine patients had a cemented revision with impaction grafting and a long or short stem. The remaining 17 had cemented revision without impaction grafting. Fractures treated by impaction grafting...

OBJECTIVE To compare outcome of patients with burns covering less than 15% of total body surface area(TBSA) undergoing early excision and grafting or delayed skin grafting. METHOD This was a non-randomized clinical trial including 54 patients with less than 15% TBSA burn referring to Ghotboddin Hospital of Shiraz. They were assigned to two study groups, each group including 27 patients: the e...

Tattoo removal from the forearm often requires excision and split skin grafting. The authors propose the use of a bloodless field to facilitate accurate dermal peeling, to ensure complete removal of the pigment, and to reduce operative time.

introduction: gold standard for alveolar cleft bone grafting is autogenous bone. advantage of adding the growth factors to the bone is established, so adding prf to the autogenous bone may have beneficial effects. methods:  platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. results:  autogenous bone in all (four cases) was...

background  many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for ideal material continues. methods  in the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. the autologous platelet-rich plasma (prf) was used as the sole g...

The study was designed to exploit the single photon emission computerized tomography (SPECT) to compare osteoblastic activity of two implant systems: an Endopore implant (Beaded implants) placed immediately into an extraction socket in conjunction with peri-implant autogenous grafting supplemented with a guided tissue regeneration (GTR) technique, and an Endopore implant placed immediately into...
