OBJECTIVE: To investigate the progress of clinical application of implant during distraction osteogenesis in the jaw bones, and to evaluate its biocompatibility.METHODS: The first author retrieved CNKI database from 1989 to 2009 in Chinese and Medline database from 1989 to 2009 in English with the key words of "jaw, distraction osteogenesis, treatment". A total of 56 articles were screened according to inclusion and exclusion criteria. Finally, 20 articles concerning treatment progress of distraction osteogenesis and clinical application of implant were included.RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate. A distraction was selected in accordance with patients' condition and requirement. Distraction osteogenesis had been an important manner for complicated tooth jaw facial deformity and jaw defect in oral dentofacial surgery and Orthodontic treatment. It could have effective osteogenesis in combination with various systemic therapy, local therapy and physical therapy. Presently, distraction osteogenesis implants were metal materials. Metal implants have great advantages in preventing bacterium growth, keeping implant fixation and distraction effects, and the price was high. However, the cost of Ni-Ti memory alloy wire was lower compared with common retractors. The fixing device and alloy wire closely adhered to the bone could be completely implanted into tissues, with the advantages of anti-infection and completely closing the exterior and interior wound. CONCLUSION: Distraction osteogenesis is a new method for treating dental and craniofacial hypodevelopment straightening of teeth and for repairing jaw bone defect deformation. Biocompatibility of metal implants was good such as internal small Ni-Ti memory alloy wire. The biocompatibility of other types of implants should be improved.

Objective To evaluate the efficacy of D98A,a newly developed superparamagnetic oral MRI contrast agent,in the diagnosis of abdomen.Methods Plain and contrast MRI after taking 500～1000 ml D98Ain 80 patients were performed by using different field strength MR scanners,and the sequences included T 1WI,T 2WI,and fat suppressed sequences.The contrast effect,distribution,influence on demonstration of contours of abdominal organs,and side effects were studied concerning this suspension.Results It showed that this oral contrast agent had good security character,wide consideration area,low cost,good contrast effect,and high value of clinical application.The gastrointestinal tracts appeared as hypointensity on various MR sequences,and thus,made them easy to be identified.The margins of abdominal organs were easier to be located after taking the contrast,and the distinction had statistical denotation.The demonstration rate of gastrointestinal tracts was raised from 10% to 89% after using D98A.There were no side-effects in all patients. Conclusion D98A is safe and effective in facilitating the localization of the abdominal organs.It can improve the accuracy in delineating the gastrointestinal tracts and in diagnosing the lesions of abdominal organs.
