Implant treatment for two central incisors in the maxillary aesthetic region is complex due to concerns regarding inter-implant hard and soft tissue stability. A treatment protocol was therefore developed and implemented in a 1-year prospective case series study involving 16 patients with two failing or missing central incisors in the maxillary aesthetic region. The protocol consists of five options depending on whether teeth are still present (options 1-3) or not (options 4 and 5) and on the amount of bone available at the start of treatment: (1) extraction followed by immediate implant placement and provisionalization, (2) extraction followed by immediate implant placement and delayed provisionalization, (3) extraction followed by ridge preservation, delayed implant placement and immediate provisionalization, (4) delayed implant placement and guided bone regeneration with delayed provisionalization, (5) guided bone regeneration (extensive bone augmentation of the alveolar ridge), delayed implant placement, and delayed provisionalization. The patients were assessed regarding peri-implant hard and soft tissue parameters, aesthetic index score, and patient satisfaction. All treatment options showed good clinical and radiographic results and high patient satisfaction.
上颌美学区两颗中切牙的种植治疗较为复杂，因为这会涉及到种植体间软硬组织的稳定性问题。因此，我们制定了一个治疗方案，并在一项为期 1 年的前瞻性病例系列研究中对 16 名上颌美学区两颗失败或缺失中切牙的患者进行了实施。该方案包含了五种选择，具体取决于牙齿是否还存在（选项 1-3）或不存在（选项 4 和 5）以及治疗开始时可用的骨量：（1）拔牙后立即植入并临时修复，（2）拔牙后立即植入并延迟临时修复，（3）拔牙后进行牙槽嵴保存、延迟种植并立即临时修复，（4）延迟种植并进行引导骨再生和延迟临时修复，（5）引导骨再生（牙槽嵴的广泛骨增量）、延迟种植并延迟临时修复。我们评估了种植体周围软硬组织参数、美学指数评分和患者满意度。所有治疗方案均取得了良好的临床和影像学效果以及高患者满意度。
