Abstract

Abstract: The patient had been missing right maxillary posterior teeth for several months and requested implant restoration. CBCT examination revealed an alveolar bone height of less than 5 mm in the edentulous area, an inclined sinus floor morphology, and low bone density. A combination of bone densification technique and plasma matrix was used to perform transalveolar sinus floor elevation and implant placement simultaneously. No sinus membrane perforation occurred intraoperatively, and no postoperative infections or complications were observed. A six-month follow-up showed successful osseointegration, sufficient bone volume, and smooth completion of the second-stage surgery, impression-taking, and final prosthetic restoration. In this case, the bone densification technique enhanced bone density by compacting bone and elevating the sinus membrane. The plasma matrix, rich in growth factors, effectively protected the sinus membrane, reduced potential complications, and improved bone regeneration outcomes.
