Abstract：
The importance of augmenting the peri-implant soft- and hard-tissue architecture is now widely accepted. However, while most contemporary research supports this premise, clinicians are encountering peri-implant soft tissue defects with increasing frequency, which they are therefore required to reconstruct. These complications can result from the difficulty of establishing an appropriate diagnosis and treatment plan or from suboptimal clinical situations (implant malposition, insufficient vestibular alveolar bone thickness or inadequate mucosal thickness). In this context, it is the peri-implant soft-tissue phenotype that most influences esthetic and health-related results in the short and long term. This article describes two clinical cases in which a modification of the apical access technique is presented that may be useful in clinical scenarios requiring large gains in mucosal thickness. Use of the modified bilaminar apical access with de-epithelialized free gingival graft technique showed promising results, with a significant increase in mucosal thickness and satisfactory outcomes in esthetics and peri-implant health.
摘要：
现在，增强植入物周围软硬组织结构的重要性已被广泛接受。然而,虽然大多数当代研究都支持这个前提，临床医生遇到种植体周围软组织缺损的频率越来越高，因此，他们需要重建。这些并发症可能是由于难以建立适当的诊断和治疗计划或不良的临床情况（植入物错位，前庭牙槽骨厚度不足或粘膜厚度不足）。在这种情况下，种植体周围软组织表型在短期和长期对美学和健康相关结果的影响最大。本文介绍了两个临床病例，其中提出了对根尖通道技术的修改，这可能在需要粘膜厚度大幅增加的临床情况下有用。使用改良的双层根尖通道和去上皮化的游离牙龈移植技术显示出有希望的结果，粘膜厚度显着增加，美学和种植体周围健康的结果令人满意。
