We post-examined 112 apicectomies in 93 patients after an average placement period of 4.8 months (3-15.3 months) both clinically and radiologically in a prospective study to evaluate the security of success using zirconoxide ceramic pins. Clinical functioning was examined by means of the clinical mobility test, the periotest method, the sulcusfluidflowrate (periotrontest), measurements of the depths of parodontal pockets at 6 points and the papillary bleeding index in comparison to the contralateral comparative tooth. To assess the osseous regeneration of the resection defect, we carried out planimetric evaluations of standardized X-ray tooth film exposures during surgery as well as at the post-examination. The resected teeth revealed an average loosening of 10.2 in periotest. The sulcusfluidflowrate came to an average of 26.1 (control group: 22.7); the parodontal pockets were an average of 0.2 mm deeper than those of the control teeth. After 4.8 months, 63.54% of the resection defect showed complete osseous regeneration. Considering the clinical and the radiological criteria, the rate of success was 85%. Clinical use of zirconoxide ceramic pins is recommended. The high radiolucency of zirconoxide ceramics permits a safe assessment of the osseous regeneration and therefore a safe assessment of resection success.
在一项前瞻性研究中，我们在平均植入期4.8个月（3 - 15.3个月）后，对93例患者的112例根尖切除术进行了临床和放射学的术后检查，以评估使用氧化锆陶瓷桩的成功安全性。通过临床松动度测试、牙周探针法、龈沟液流速（牙周流量测试）、6个位点的牙周袋深度测量以及与对侧对照牙相比的乳头出血指数来检查临床功能。为了评估切除缺损处的骨再生情况，我们在手术期间以及术后检查时对标准化X线牙片进行了面积测量评估。切除的牙齿在牙周探针检查中平均松动度为10.2。龈沟液流速平均为26.1（对照组：22.7）；牙周袋比对照牙平均深0.2毫米。4.8个月后，63.54%的切除缺损显示完全骨再生。综合临床和放射学标准，成功率为85%。推荐临床使用氧化锆陶瓷桩。氧化锆陶瓷的高射线透过性允许对骨再生进行安全评估，从而对切除成功进行安全评估。
