目的
这项前瞻性临床研究的目的是评价假体修复后3年随访期间的种植体周围软组织状况和美学实现。
材料和方法
作为一项前瞻性多中心研究的一部分，在80名患者的上颌前部区域植入了152个ITI牙科种植体。59个冠（38.82%）为骨水泥固位，93个冠（61.18%）为螺钉固位。在加载时和加载后3、6、12和36个月，记录改良菌斑指数（MPI）、龈沟出血指数（SBI）、角化粘膜（KM）、牙龈水平（GL）和美学满足度。
结果
所有患者均完成了研究，未报告并发症。虽然在所有时间点上没有统计学意义，但骨水泥固位冠似乎在MPI和SBI评分方面呈现恶化趋势。有趣的是，螺钉固位冠似乎呈现出相反的情况，他们的MPI和SBI评分随着时间的推移而改善。虽然菌斑积累，预防和冠缘深度显着影响龈沟出血的水平，预防单独发挥了关键作用，减少菌斑积累。加载后3年，在骨水泥或螺钉固位冠中均未观察到软组织退缩。美学满意度调查显示，患者对牙冠类型没有偏好;然而，牙科医生更喜欢骨水泥固位而不是螺钉固位牙冠。
结论
与骨水泥固位冠相比，种植体周围软组织对螺钉固位冠的反应更好。然而，在两种类型的牙冠中均未观察到软组织退缩。牙科医生更喜欢使用骨水泥固位冠，而患者对他们收到的任何类型的冠都同样满意。
OBJECTIVE
The purpose of this prospective clinical study was to evaluate peri-implant soft-tissue conditions and esthetic fulfillment during a 3-year follow-up period following prosthetic rehabilitation.
MATERIAL AND METHODS
As part of a prospective multi-center study, 152 ITI dental implants were placed in 80 patients in the maxillary anterior region. Fifty-nine crowns (38.82%) were cement retained, while 93 (61.18%) crowns were screw retained. At loading and 3, 6, 12 and 36 months post-loading, modified plaque index (MPI), sulcus bleeding index (SBI), keratinized mucosa (KM), gingival level (GL), and esthetic fulfillment were recorded.
RESULTS
All patients completed the study and no complications were reported. While statistically not significant at all time points, cement-retained crowns seemed to present a worsening trend in MPI and SBI scores. Interestingly, screw-retained crowns seemed to present an opposite picture, their MPI and SBI scores improved over time. While plaque accumulation, prophylaxis and depth of crown margin significantly affected levels of sulcus bleeding, prophylaxis alone played a key role in reducing plaque accumulation. No soft tissue recession was observed in either cement- or screw-retained crowns up to 3 years post-loading. Esthetic fulfillment survey revealed that patients did not have a preference for crown types; however, dentists favored cement-retained over screw-retained crowns.
CONCLUSIONS
Peri-implant soft tissues responded more favorably to screw-retained crowns when compared with cement-retained crowns. However, no soft-tissue recession was observed in either type of crowns. Cement-retained crowns were preferred by dentists, while patients were equally satisfied with either type of crowns they received.
