Forty patients received a total of 43 implants placed in fresh extraction sites in the anterior maxilla. Within 1 week, a provisional crown was placed without occlusal contact. After 1 year, the implant survival rate, marginal bone resorption, and papillae preservation were assessed. The overall survival rate was 95.3%. The 1-year marginal bone loss was not statistically significant when compared to the marginal bone level at implant placement. In 78% of patients, the papilla was completely preserved. Single-tooth rehabilitation patients with buccal or circumferential defects can be predictably treated with a favorable esthetic outcome using the immediate provisionalization approach.
40名患者在前上颌新鲜拔牙位点共植入43颗种植体。在1周内，放置了临时冠，使其无咬合接触。1年后，评估种植体存活率、边缘骨吸收和乳头保留情况。总体存活率为95.3%。与种植体植入时的边缘骨水平相比，1年的边缘骨丢失无统计学意义。78%的患者乳头得以完全保留。对于有颊侧或环形缺损的单颗牙修复患者，采用即刻临时修复方法可获得可预测的良好美学效果。
