Alveolar bone resorption and maxillary sinus pneumatization occurring after dental extraction in the posterior region of the maxilla may be problematic when planning implant-supported rehabilitation. Various regenerative options are available, including guided bone regeneration, bone block grafts, and lateral sinus augmentation. These procedures are associated with significant complication rates, high morbidity, increased therapy duration, and high cost. Less invasive approaches, such as transcrestal sinus floor elevation, and using short implants have been proposed in an attempt to reduce these drawbacks. The aim of this study is to analyze available evidence to suggest predictable options and identify minimally invasive management of implant-supported rehabilitation in the posterior maxilla. This article concerns biologic mechanisms regulating new bone formation after maxillary sinus augmentation and examines characteristics of available implants and grafting materials to help the clinician select the most rational and convenient surgical approach according to specific situations.
在上颌后部拔牙后发生的牙槽骨吸收和上颌窦气化，在计划种植体支持的修复时可能会出现问题。有多种再生方法可供选择，包括引导骨再生、骨块移植和外侧上颌窦增高术。这些手术伴有较高的并发症发生率、高发病率、治疗时间延长和高成本。为了减少这些缺点，人们提出了侵入性较小的方法，如经牙槽嵴上颌窦底提升术和使用短种植体。本研究的目的是分析现有证据，以提出可预测的选择，并确定上颌后部种植体支持修复的微创管理方法。本文关注调节上颌窦增高术后新骨形成的生物学机制，并研究现有种植体和移植材料的特性，以帮助临床医生根据具体情况选择最合理、最便捷的手术方法。
