Abstract:

BACKGROUND: Mucosal perforation is the most common complication in open maxillary sinus lift, which limits the clinical application of dental implantation. Clinical effects of precise operation in open maxillary sinus lift with dental implant for mucosal perforation.

 
OBJECTIVE: To analyze the cause of mucosal perforation in maxillary sinus lift with dental implant and to observe the effect of dental implantation after perforation closure.
METHODS: Twenty-nine cases underwent open maxillary sinus lift (39 implants). Mucosal perforation was repaired by absorbable biofilms, and coralline hydroxyapatite was used as a bone graft material in open maxillary sinus lift.
RESULTS AND CONCLUSION: Eight of 29 cases (20.5%) developed mucosal perforation, among which, 5 were repaired and implanted instantly, and the other 3 cases underwent sinus lifting and delayed dental implantation. No infection occurred, and only one case appeared to have implant shedding. All the 29 cases (39 dental implants) completed the restoration, and no implant loosening and pain occurred. These findings indicate that mucosal perforation in maxillary sinus lift is mainly related to the mucosal condition of the sinus floor, choice of operating instruments and surgeon’s operating skill. Based on the proper mucosal repair and appropriate selection of dental implants, open maxillary sinus lift with instant or delayed dental implantation can both achieve satisfactory effects.
