Objective To retrospectively analyze the indication of endosseous dental implant,evaluate the effectiveness of clinical application of endosseous dental implant for tooth loss,and study the possible factors which may affect the success rate of implant denture.Methods One hundred and fifty-seven endosseous dental implants in 94 patients were followed up for 4 months to 8 years.The indications of endosseous dental implant were studied based on the changes in the distribution of dental implants in jawbone.The success rate of osseointegration and restoration of the endosseous dental implant were evaluated by checking the soft tissue around the implants,the stability of the implants,the bone resorption around the implants,and the degree of stability against rotation of the implants.Results The rate of performing endosseous dental implant for restoration of full-mouth anodontia was 7.6%,the rate of endosseous dental implant used in the free end anodontia was 25.5%,and it was 66.9% in non-free end anodontia.The success rate of osseointegration in the endosseous dental implant was 98.1%,and 5 years after prosthesis the success ratio of the endosseous dental implant was 93.8%.The success ratio of the endosseous dental implants which the primary stability(anti-rotation torsion)

ObjectivesTo investigate the effect of pediatric trauma life support (PTLS) curriculum on the improvement of rescue skill for pediatric trauma patients.MethodsPTLS course was introduced to train medical staff engaging in pediatric critical trauma care. The course included theoretical and practical part with main focus on enhancement of students’ decision on scene and rescue skill.ResultsCompared with pre-training, the students’ post-training written test scores improved signiifcant-ly, and the rates of qualiifcation and excellence were improved signiifcantly (P<0.01). All students were qualiifed for the tests of skill stations and simulation scenario. The excellence rates of the tests were as follows: ifxation and transportation 42.62%, basic and advanced airway management 81.97%, shock evaluation and management 70.49%, simulation scenario 72.13%. Both pre-training and post-training written test scores in hospital group were significantly higher than those in pre-hospital group (P<0.01).ConclusionsAfter PTLS courses, the knowledge, practice and integrated life-saving skills of students are greatly im-proved and teamwork is strengthened.
