目的 评价经过牙周系统治疗的重度牙周炎，对种植体周围组织早期的影响。方法 选择12例重度牙周炎患者为试验组，植入38枚Straumann种植体；15例无牙周炎患者为对照组,植入25枚Straumann种植体。分别于种植修复后1年和2年检测改良菌斑指数、改良龈沟出血指数、探诊深度及X线片检测，进行临床评价和比较。结果 对照组与实验组改良菌斑指数（0.58±0.08 vs 0.61±0.10）、改良龈沟出血指数（0.61±0.11 vs 0.64±0.12）、探诊深度（2.15±0.58 vs 2.26±0.63）及骨质吸收状况（0.21±0.10 vs 0.24±0.09）差异均无统计学意义(P>0.05)。结论 对经过牙周系统治疗的重度牙周炎,进行种植义齿修复可以获得满意的修复效果，但长期效果需要进一步观察。
Abstract
Objective To study the early effect of systemical therapy on peri-implant tissues in patients with severe periodontitis. Methods Fifteen periodontally healthy patients and twelve patients with severe periodontitis(SP) were enrolled in this study. Periodontally healthy patients received 25 Straumann implants while the SP patients received 38 Straumann implants.One and two years after prosthesis, the modified plaque index,modified sulcus bleeding index,probing depth ,and X-ray examinations were recorded in an standard manner. Results There was no significant difference between periodontally healthy patient group and the SP patient group in all the clinical parameters recorded(P>0.05). Conclusion Prosthesis can produce satisfactory effect on partially edentulous patients who receive systemical therapy for severe periodontitis, but long-term effects need to be observed in the future.
