牙保存相关上颌窦底提升术的局部风险因素分析OA

Natural tooth-related maxillary sinus floor elevation has emerged as an effective approach for maintaining natural teeth after the adequate control of endodontic infection and resolution of periapical disease. The procedure is per-formed within the anatomical context of the maxillary tooth-bone-sinus complex,and its success is largely determined by careful consideration of multiple local anatomical and biological factors. This article addresses tooth-related factors (such as root length and spatial position),alveolar bone conditions (including residual bone height and proximity to the greater palatine neurovascular bundle),and maxillary sinus ana-tomy (including sinus floor configuration and Schneide-rian membrane thickness),in addition to the positional relationship between tooth roots and the maxillary sinus.By systematically evaluating these site-specific risk fac-tors,this article aims to inform preoperative assessment and treatment planning and enhance surgical safety,cli-nical predictability,and long-term treatment outcomes.
