摘要: 患者右上后牙缺失数月要求种植修复,CBCT检查示缺牙区牙槽骨高度不足5 mm,上颌窦底形态倾斜且骨密度低。采用骨致密化技术结合血浆基质,同期完成穿牙槽嵴上颌窦底提升及种植体植入。术中未发生上颌窦膜穿孔,术后无感染等并发症。术后6个月复查示种植体骨结合良好,骨量充足,顺利完成二期手术、取模和最终修复。本病例中使用骨致密化技术,通过挤压骨质提升上颌窦底黏骨膜增加骨密度,该技术结合血浆基质,其内富含生长因子,有效保护了上颌窦底黏骨膜,减少了潜在并发症,提高了骨再生效果。

Abstract: The patient had been missing right maxillary posterior teeth for several months and requested implant restoration. CBCT examination revealed an alveolar bone height of less than 5 mm in the edentulous area, an inclined sinus floor morphology, and low bone density. A combination of bone densification technique and plasma matrix was used to perform transalveolar sinus floor elevation and implant placement simultaneously. No sinus membrane perforation occurred intraoperatively, and no postoperative infections or complications were observed. A six-month follow-up showed successful osseointegration, sufficient bone volume, and smooth completion of the second-stage surgery, impression-taking, and final prosthetic restoration. In this case, the bone densification technique enhanced bone density by compacting bone and elevating the sinus membrane. The plasma matrix, rich in growth factors, effectively protected the sinus membrane, reduced potential complications, and improved bone regeneration outcomes.
