外胚层发育不全患者上下颌骨重建及全口种植固定修复

Computer assisted jaw reconstruction and full arch fixed implant restoration for ectodermal dysplasia patient

为了探讨外胚层发育不全无牙颌患者的软硬组织增量及种植固定修复方法,采用数字化手段辅助下进行髂骨移植,恢复上下颌骨缺损。在种植导板辅助下完成种植体植入,骨结合后进行游离龈移植,增加植体周围角化龈宽度及软组织厚度,并同期完成二期手术。通过种植体支持式固定临时义齿验证咬合及美观,最终完成上下颌一段式螺钉固位种植义齿修复。结果表明上下颌骨骨增量效果良好,种植体骨结合稳定,种植体周围角化龈宽度充足,最终修复体美学效果及咀嚼功能良好。修复完成后24个月复查,修复效果稳定。对外胚层发育不全患者进行软硬组织增量,并行种植固定修复,是一种有效的治疗手段,短期效果良好。

To investigate clinical approach of bone and soft tissue reconstruction and fixed implant restoration for dysplasia patient.Jaw reconstruction was done by iliac graft with digital guide and implants were placed under surgical guide.Free gingiva graft and second stage surgery was applied after implant osseointegration.Function and esthetic outcome was verified through fixed temporary restoration.Full arch screw retained fixed prosthesis was delivered for final restoration.Bone volume was good enough for implant placement.Implant ossteointegration was successful with enough keratinized tissue around implant after free gingiva graft.Patient was satisfied with the esthetic and masticatory function.The result was stable at 24 months follow-up.Fixed implant restoration for ectodermal dysplasia patient after hard and soft tissue augmentation was an effective therapy approach.Short-term result was stable.
