Abstract

Objective To observe the effect of maxillary sinus floor augmentation with transalveolar technique and simultaneous implant. Methods 50 cases of patients with missing tooth in maxillary posterior region with insufficient vertical bone treated by author were selected.Maxillary sinus floor augmentation with transalveolar technique and simultaneous implantation were given after local anesthesia.X-ray was given on the right day, 2 weeks, 3 months and 9 months after operation.And the situation of osseointegration was observed. Results There were 2 cases of injuries of maxillary sinus mucoperiosteum in the 50 cases (4%), and no obvious complication was found for timely treatment.There were 5 cases of gingiva with obviously swollen around implant and BOP(+ ), and the symptoms were obliterated one week after paradental basic therapy and oral health guidance were given.All the situations of the osseointegration of implants were good, and no loosening or dropping case was found in follow up.One year after operation, the mean obsorbation of bone around the neck of implant was (0.9±0.3)mm.There was no obvious absorption of bone around implant, and obvious continuous image of maxillary sinus floor could be observed by imaging examination.The satisfaction of chew, pronounce, aesthetics, maintenance and comfort was all 100%, and 49 cases were satisfied with operation tolerance, and satisfaction rate was 98%. Conclusion Ther effect is desired to apply maxillary sinus floor augmentation with transalveolar technique and simultaneous implant under strict indication.And the satisfaction degree is high.
