A "team approach" that includes different specialties from the initial stages of implant treatment is important to achieve predictable and esthetically pleasing outcomes in compromised dental replacement cases. This report describes a severely compromised case that was properly managed by the combined efforts of a team of specialists. Briefly, prior to tooth extraction, orthodontic forced eruption was applied to coronally displace the attachment apparatus (i.e., hard and soft tissues). Then, atraumatic tooth extraction together with immediate implant placement was performed. The "sandwich bone augmentation" technique was used to augment the deficient buccal alveolar ridge. A second stage surgery was performed 6 months after healing, revealing 100% of bone fill/augmentation. This technique allowed fabrication of a final restoration that respected the proportions of the natural dentition in a case that would otherwise result in a poor esthetic outcome.
在复杂的牙列缺失病例中，从种植治疗的初始阶段就采用包括不同专业的“团队协作方法”，对于实现可预测且美观的治疗效果至关重要。本报告描述了一个严重复杂的病例，该病例通过一组专家的共同努力得到了妥善处理。简而言之，在拔牙前，采用正畸性牙齿强制萌出术使附着装置（即硬组织和软组织）向冠方移位。然后，进行了无创拔牙并即刻植入种植体。采用“三明治骨增量”技术来增加颊侧牙槽嵴骨量不足的区域。愈合6个月后进行了二期手术，显示骨填充/增量达到100%。在原本会导致美学效果不佳的病例中，该技术使得最终修复体能符合天然牙列的比例。
