摘　　要：通过一例上颌后牙区剩余骨高度不足伴颌间距离严重不足的种植修复病例报告分析,为此类患者的治疗提供一定参考。本病例先行其他牙的咬合重建抬高部分咬合,咬合重建后颌间距离依旧不足,进而在种植位点行穿牙槽嵴上颌窦底提升及骨增量手术,为后期种植体的植入创造周围骨包绕的稳定条件,8个月后再行第二次穿牙槽嵴上颌窦底提升并同期骨下深部植入锥度固位短种植体,复诊显示骨结合良好,永久修复2年后复诊显示种植体周围骨组织稳定。分析认为在上颌后牙区剩余骨高度及颌间距离均严重不足的情况下,可先行上颌窦底提升及骨增量,创造延期种植时种植体周围骨包绕的稳定条件,第二次种植时再进行上颌窦底提升及短种植体深部植入,进而为后期修复创造足够的修复空间来完成最终修复。This paper reports on the implant restoration of a case with severely insufficient residual bone height and limited interarch distance in the maxillary posterior region,aiming to provide reference value for the treatment of such patients.In this case,occlusal reconstruction of other teeth was performed first to raise a portion of the occlusion.However,after occlusal reconstruction,the interarch distance remained insufficient.Subsequently,transalveolar sinus floor elevation and bone augmentation surgery were performed at the implant sites to create stable conditions for the late implant placement with surrounding bone.A second transalveolar sinus floor elevation was performed 8 months later,with two taper-retained short implants placed deep under the bone level simultaneously.Follow-up examinations indicated good osseointegration.The peri-implant bone tissue was shown to be stable during the follow-up 2 years after the permanent restoration.Therefore,if the residual bone height and interarch distance in the maxillary posterior region are severely insufficient,transalveolar sinus floor elevation and bone augmentation can be performed first to create a stable condition for bone integration around the implant during late implant placement.Then transalveolar sinus floor elevation and the deep implant placement of short implants can be carried out during the second surgery to create sufficient restorative space for the final restoration.
