| Popis: | Objectives This case series aimed to explore the clinical outcome of sinus floor elevation surgery using a crestal approach technique in case of severely resorbed maxillae. Material and methods Seventeen edentulous patients received 20 implants and sinus floor elevation in posterior maxillae with residual crestal height of 1.2-5.0 mm and >7 mm. Drilling perforation was performed until the sinus floor was felt; the sinus mucosa was then lifted and magnesium-enriched hydroxyapatite granules (Mg-e HAP) were placed; and implants were immediately inserted. Four months later, definitive crowns were cemented, and patients were followed up for 24 months. Implant failures and complications 24 months after prosthetic loading were noted, and radiographic regenerated bone height was measured. Results No patient dropped out, and all implants were successfully osseointegrated. There was minimal postoperative patient discomfort, and the only complication was a minimal perforation of the sinus membrane with no negative consequences. At the time of implant insertion, the residual crestal height mean value was 4.12 mm. After surgery and at the last follow-up, the mean heights of bone were 13.51 and 12.98 mm, respectively. Conclusion The procedure was able to obtain sinus elevation and implant osseointegration. |
