摘要: 上颌磨牙作为牙周炎的好发牙位之一,根周及根尖区的骨缺损可能波及邻近的上颌窦,增加后期种植修复的风险和复杂程度。而在微创拔牙、彻底清创同期,利用拔牙位点保存可处理上颌窦底骨缺损,并维持牙槽骨的高度和轮廓,减少后期对上颌窦底提升的需求,降低手术风险,简化治疗过程,获得良好的种植修复效果。文章完整展示了1例伴有重度牙周病变致上颌窦底骨缺损的上颌磨牙,包括病情分析、治疗设计、采用微创拔牙及拔牙位点保存创造良好硬组织条件、完成种植修复并随访17个月的具体实施过程,为此类伴有上颌窦底骨缺损的重度牙周病变磨牙的临床处置积累了经验。

Abstract: Maxillary molars with severe periodontal lesions are often accompanied with bone defects even reaching the corresponding maxillary sinus floor. These bone defects will increase the difficulty and risk for implantation after the extraction of maxillary molars. The application of minimally invasive extraction with thorough debridement and site preservation of the maxillary molars can not only maintain the dimensions of alveolar ridge, but also reduce the requirement of sinus floor elevation.This paper illustrates the treatment procedures of implant replacement of a maxillary molar with severe periodontal lesions involving maxillary sinus floor using this technique.Changes of bone conditions were compared and analyzed in order to provide evidence and clinical experience for the management of similar cases.
