Objective:
To introduce and evaluate the procedure and the effect of localized management of sinus floor (LMSF), bone graft and simultaneous implant placement with trephine bur in maxillary posterior region.
Methods:
24 patients without enough alveolar bone height received LMSF, bone grafting and implants placement were carried out simultaneously.The autogenous bone were harvested by trephine bur in situ. Patients were followed up after 1 week, 1, 3 and 6 month.
Results:
There was no implant loose or lost and maxillary antritis. 6 months postoperatively, bone graft reformed to new bone seen in X-ray films, sinus floors were augmented and reached the requirements of dental implants. The implant osseointegrated tightly with new bone which was satisfactory to second-step prosthesis after implant placement of 6 months later.
Conclusions:
The method enlarges the indication of dental implants and avoids operation of harvesting autogenous bone in other site. It is simple and valuable to clinical application.
