Abstract：
BACKGROUND: Sporadic studies have reported the occurrence of nasopalatine duct cysts after maxillary anterior implant surgery, and the treatment methods still have clinical uncertainty.
OBJECTIVE: We report a potential therapy method that successfully treated a nasopalatine duct cyst that developed and expanded one year after maxillary anterior implant placement following periodontally hopeless teeth extraction.
METHODS: The nasopalatine cyst was treated surgically without removing implants. During flap surgery, the cyst was removed intact, and the exposed implant\'s surface was debrided thoroughly by hydrogen peroxide (H2O2) rinsing, glycine air polishing, and saline rinsing. To deal with the significant bone defect caused by the cyst, a bovine porous bone mineral injected platelet-rich fibrin (BPBM-i-PRF) complex was applied to fill the defect, following a resorbable collagen membrane to cover.
RESULTS: 7 years after surgery, no cyst recurrence was observed, and bone regeneration in the bone graft area was stable. The implants functioned well without mobility.
CONCLUSIONS: For nasopalatine duct cysts associated with dental implant placement, complete surgical debridement and longitudinal stable bone regeneration are possibly accessible by regenerative surgery without implant removal.

摘要：
背景：散发性研究报道了上颌前路植入物手术后鼻腭管囊肿的发生，治疗方法仍存在临床不确定性。
目的：我们报告了一种潜在的治疗方法，该方法成功治疗了无牙周病拔除后上颌前牙种植体放置一年后发展和扩大的鼻腭管囊肿。
方法：鼻腭囊肿手术治疗，不切除植入物。皮瓣手术期间,囊肿被完整切除,和暴露的植入物的表面被彻底清创过氧化氢（H2O2）冲洗，甘氨酸空气抛光，和盐水冲洗。处理由囊肿引起的显著骨缺损，应用牛多孔骨矿物质注射富血小板纤维蛋白（BPBM-i-PRF）复合物来填充缺损，遵循可吸收的胶原膜覆盖。
结果：手术后7年，未观察到囊肿复发,骨移植区的骨再生稳定。植入物功能良好，没有移动性。
结论：对于与种植牙相关的鼻腭管囊肿，完整的手术清创和纵向稳定的骨再生可能通过再生手术获得，而无需移除植入物。
