“Objective. The aim of this paper is to present the outcome of iliac bone block grafts used for paranasal augmentation during bimaxillary orthognathic surgery
for the patient with deep concavity of canine fosse.
Study design. Preoperative evaluation of the patient, done with 3-dimensional (3D) surgical simulation software, revealed deep bony concavity of paranasal area and insufficient soft tissue improvement when Le Fort I level maxillary advancement was accomplished. The deficient sites were grafted and better profile was ACY-738 clinical trial achieved with 3D simulation. After the leveling phase, Le Fort I advancement and mandibular setback with sagital split osteotomies were performed. Bony deficiency of paranasal regions were corrected simultaneously with autogenous iliac block grafts to obtain maximum improvement in the profile.
satisfactory esthetic results were obtained with paranasal augmentation, and acceptable profile was provided for the patient.
Conclusions. Bimaxillary orthognathic surgery combined with augmentation of paranasal area is an selleck kinase inhibitor efficient method to obtain better aesthetic outcome for patients with severe concave profile. Paranasal augmentation with iliac bone block grafting is a novel technique to ensure favorable soft tissue support and esthetic appearance of the patient.

“Three cold-cured epoxy resins, specifically designed as structural adhesives for rehabilitation or renewal applications of civil infrastructures and cultural heritage, were submitted to natural and artificial weathering. We evaluated the variations in the thermal and mechanical properties and color changes after an artificial treatment carried out at 70 degrees C and 75% relative humidity and after natural weathering, performed in two areas of South Italy, both located adjacent to the Mediterranean Sea. The variations in properties due to both natural exposure and artificial weathering were qualitatively similar. However, the selected artificial weathering procedure appeared excessively severe compared to the weathering that occurred after outdoor exposure. (C) 2010 Wiley Periodicals, Inc.

“Study Design. In vitro study of genipin crosslinking effect on disc water content changes under compressive loading and unloading.
Objective. To investigate the influence of collagen crosslinking on hydration and fluid flow in different regions of intact discs, and to evaluate the nutritional implications.
Summary of Background Data. Age-related reductions of nutrient supply and waste product removal are critically important factors in disc pathogenesis.
