In a prospective study, the influence of the status of the peri-implant hard and soft tissues on the success of enosseous dental implants in tumor patients was assessed. Out of 59 tumor patients with 261 implants, treated between July 1988 and August 1996, a pool of 23 patients with 99 implants provided with dentures for at least 1 year was obtained. Eighteen of these patients suffered from a squamous cell carcinoma of the oral cavity. Seventeen patients underwent preoperative radiation (40 Gy). A total of 68 out of 99 implants were inserted into autologous bone transplanted to reconstruct the mandible. In order to assess the peri-implant hard and soft tissues, the Hygiene Index, the Sulcus Bleeding Index, the Gingiva Index, the pocket-probing depth. the peri-implant bone resorption, and the periotest were used. The results in the tumor patients were compared with the results in a pool of nontumor patients. Tumor patients had significantly worse periimplant parameters than nontumor patients. The peri-implant pocket-probing depth proved to have significant influence on the success rate. The overall success rate was 77.8%.
在一项前瞻性研究中，评估了种植体周围软硬组织状况对肿瘤患者骨内牙种植体成功的影响。在1988年7月至1996年8月期间接受治疗的59例肿瘤患者（共植入261颗种植体）中，选取了23例患者（共99颗种植体），这些患者佩戴假牙至少1年。其中18例患者患有口腔鳞状细胞癌。17例患者接受了术前放疗（40 Gy）。99颗种植体中有68颗植入了用于重建下颌骨的自体骨。为了评估种植体周围软硬组织，使用了卫生指数、龈沟出血指数、牙龈指数、探诊深度、种植体周围骨吸收和牙周膜电刺激仪。将肿瘤患者的结果与一组非肿瘤患者的结果进行比较。肿瘤患者的种植体周围参数明显比非肿瘤患者差。种植体周围探诊深度被证明对成功率有显著影响。总体成功率为77.8%。
