牙保存相关上颌窦底提升术的临床应用OA北大核心CSTPCD

The posterior maxillary teeth are common sites of endodontic periapical diseases and are connected to the maxillary sinus,facilitating the spread of infection and leading to odontogenic maxillary sinusitis.The maxillary tooth-bone-sinus complex exhibits a close anatomical relationship,necessitating procedures for refractory cases.For surgical ac-cess,microscopic apical surgery is often combined with maxillary sinus floor elevation,termed"natural tooth-re-lated maxillary sinus floor elevation",to ensure thera-peutic efficacy and reduce complications.This paper provides a comprehensive discussion on the application scenarios,advantages,indications and contraindications,treatment planning,and selection of surgical procedures for tooth preservation-related maxillary sinus floor elevation.Drawing from a combination of literature review and clini-cal experience,this work explores the clinical applications of this technique and provide preliminary theoretical guidance on its clinical application and a solid foundation for further standardization of the clinical operation path and multidisci-plinary joint management strategy.
