| 1 | Comparison of Maxillary Implant-Supported Prostpesis in Irradiated and Non-Irradiated Patients显示文摘Summary: In order to investigate the influence of radiation therapy after the treatment of maxillaryimplant-supported prostheses, 27 patients received a total of 131 implants in maxilla after oral cancertreatment and/or reconstructive surgery. Among them, 25 received maxillary implant-supportedprostheses. The cumulative survival rates of implants and prostheses were evaluated by the product-limit-estimates method according to Kaplan-Meier. The cumulative survival rate of implants andprostheses in irradiated patients was compared with that in non-irradiated patients by statistical Log-rank test. The results showed that 112 implants were observed after implant loading. The implantscumulative survival rate was approximately 65 % for overall patients. The cumulative prosthesis suc-cessful rate was approximately 88 % for all 25 patients. Log-rank test analysis revealed that therewas a significant difference in cumulative implants survival rates between non-irradiated and irradiat-ed maxillary bone (P<0. 01). It was concluded that the implants and prostheses in irradiated pa-tients have significantly lower survival rates than in non-irradiated patients. | 曹颖光 Thomas Weischer | 2003 | Journal of Huazhong University of Science and Technology(Medical Sciences)2003，23，2： | 5 |
| 2 | 口腔肿瘤治疗后上颌种植义齿失败的分析显示文摘目的:分析口腔肿瘤治疗和重建术后患者上颌种植修复失败的影响因素。方法:27例病人,共植入131枚上颌种植体,25例患者佩戴了上颌种植义齿,12例接受了术前或术后的放射治疗,采用Kaplan-meier的方法评价种植体和修复体的生存率,Log-rank检验比较放疗和未放疗患者的种植体和修复体生存率,对所观察种植体的边缘骨吸收,种植体周围袋深度,菌斑指数,种植体周围出血指数以及吸烟与否等资料进行了统计学分析。结果:接受放疗和未接受放疗的患者之间,其种植体和修复体的5年累计生存率差异均有显著性(P<0.01);种植体周围袋深度,菌斑指数,种植体周围出血指数以及吸烟与种植义齿失败之间无显著差异。结论:放疗是影响上颌种植修复失败的主要因素,其它因素尚需进一步探索。 | 曹颖光 Thomas Weischer | 2004 | 口腔颌面修复学杂志2004，5，4： | 1 |

| 4 | Investigation of Maxillary Preprosthetic Situations after Oral Tumor Treatment显示文摘In order to investigate the maxillary preprosthetic situation after oral tumor treatment and/or reconstructive surgery, based on the review of case history and the clinical records 47 cases were analyzed after oral tumor treatment and/or reconstruction, including residual maxillary bone, intermaxillary relationships, defection of maxilla and oral situation after radiation therapy. The results showed that the residual maxillary bone was useful for implantation in the front alveolar bone and zygoma area. The maxillary preprosthetic situation after tumor treatment and/or reconstructive surgery was difficult due to maxillary resection, intermaxillary relationships, unsuitable soft and hard tissue transfer and the irradiation. It is suggested that the maxillary preprosthetic situation after oral tumor treatment is getting worse not only due to maxillary resection and/or irradiation, but surprisingly also due to mandibular resection and/or irradiation. | 曹颖光 孙国洪 Thomas Weischer | 2004 | Journal of Huazhong University of Science and Technology(Medical Sciences)2004，24，5： | 0 |
