摘　　要：BACKGROUND Transcrestal sinus floor elevation(TSFE)has been widely used in the oral clinic when the residual bone height(RBH)exceeds 5 mm.However,when there is insufficient RBH in the posterior maxilla,two-stage TSFE may be an option.CASE SUMMARY This article introduces the concept of two-stage TSFE.Six patients had osseointegration failure after TSFE.For the first-stage surgery,we restricted the vertical bone augmentation as much as possible.At the second-stage surgery,the increased RBH was 3.28±1.55 mm,which was beneficial for surgery.Five implants functioned successfully on schedule,but one implant failed again during the healing period.A third surgery was performed,and the implant functioned successfully.CONCLUSION When RBH was less than 5 mm,two or more procedures of TSFE might result in a higher RBH.
