ABSTRACT
Objective The paper proposed suggestions and measures for hospital scientific research management by statistical analyzing all the papers published from 2009 to 2013.Method By referring to research database of this hospital and by using Microsoft Excel,this research calculated the frequency distributions of different variables including quantity,publisher,disciplinary subject,and the author title as well as core author.Result 772 papers were published from 2009 to 2013,mainly in local periodicals.75.52％ of the title of first author are high-level or intermediate-level;86 core authors published 378 papers,account for 48.96％ of the total amount.Conclusion The number of research papers is increasing year by year.but the quantity and quality are still low.The research administorsshould take measures to encourage researchers to publish quality papers in periodicals with higher standards.
ABSTRACT
<p><b>OBJECTIVE</b>To Investigate the changes in dentition at each treatment stage and to get some guidelines for clinical work.</p><p><b>METHODS</b>Thirty-one cephalometric films of skeletal class III malocclusion patients were analyzed. All the patients were treated by orthodontic and orthognathic surgery.</p><p><b>RESULTS</b>During presurgical orthodontic treatment, the lower Incisors were decompensated (labially Proclined by 7 degrees ). The upper incisors were uprighted during surgery following rotation of maxilla. After surgery, the upper anterior teeth kept tipping for ward. While the lower anterior teeth were In stable. The dentition was in good occlusion during observing stage.</p><p><b>CONCLUSIONS</b>Lingually tipped lower Incisors were decompensated after presurgical orthodontic treatment in class III malocclusion patients, and lower Incisors kept in stable during observing stage, while the upper incisor had a little bit relapse.</p>

Objective: To evaluate the clinical application of MBT straight wire. Methods: 41 cases, 11 males and 30 famales aged 12-42 years old, with malocclusion were treated by MBT straight wire appliance in orthodontic clinics, follow-up was carried out. Results: Satisfactory effects were obtained in 11 completely treated cases, preliminary improvement of occlusion was observed in the other 30 cases being still in the treatment. Conclusion: MBT straight wire appliances may be used in the treatment of various malocclusion, but special consideration should be taken according to the type of occlusion in each case.
