Diagnosis, complications, and treatment of dentoskeletal malocclusion.

The frequency of correctable malocclusion makes it imperative that the condition be diagnosed and referred for appropriate treatment. A complete dentofacial examination, which assesses facial symmetry and the dentition in the transverse, sagittal, and centric relations, is appropriate. Early diagnosis is imperative because malocclusion leads to long-term complications such as temporomandibular joint (TMJ) dysfunctions, perodontal disease, obstructive sleep apnea, psychological disorders, and articulation errors. A combination of orthodontic treatment and orthognathic surgery will correct the dentoskeletal malocclusion and prevent any long-term complications. The purpose of this case report is to describe a patient with severe dentoskeletal malocclusion who benefitted from appropriate orthodontic treatment and orthognathic surgery.

Some biomechanical considerations in microsutures.

The purpose of this study was to measure the biomechanical performance for commercially available microsutures, nylon polypropylene, polyester, and polyglactin 910. The biomechanical performance was determined by reproducible, biomechanical parameters that included stiffness, elasticity, resistance to creep, secure knot construction, and knot breaking strength. On the basis of these comprehensive studies, the handling characteristics of the nylon microsutures were judged to be superior over the other microsutures. Knot security was achieved with a three-throw square (1 = 1 = 1) knot that allowed a preview of the ultimate apposition of the divided tissue. In addition, nylon microsutures were more supple than the other microsutures. The breaking strength of the knotted nylon microsutures was comparable with those of the knotted polyglactin 910 and polyester microsutures, and significantly greater than that of the knotted polypropylene sutures. Its resistance to creep was significantly greater than that of the polypropylene microsutures but less than those of polyglactin 910 and polyester microsutures.

Adaptive air travel transportation systems for persons with disabilities.

The Air Carrier Access Act ensures that no air carrier may discriminate against persons with disabilities. This Act specifies rules and regulations that remove architectural barriers to persons with disabilities. Other important considerations in the comprehensive adaptive air travel system for persons with disabilities include (1) aircraft boarding environment, (2) boarding chairs, (3) collapsible aircraft wheelchairs, (4) aircraft stowage procedures for battery-powered wheelchairs, and (5) airport shuttle bus or van service. Educational curricula must be developed that describe the comprehensive operation of this system. Evaluation of the performance of the system for persons with disabilities is mandatory to ensure that persons with disabilities have the same level of services as those without disabilities.
