Clinical and radiological comparison of a dynamic implant valve vs a hydraulic maxillary sinus lift augmentation technique with simultaneous implant insertion

The study aimed to compare between dynamic implant valve (DIVA) and the crestal ballooning techniques in elevating maxillary sinus membrane (MSM) conjunction with simultaneous implantation. Patients methods: 20-patient prospective clinical cohort study. Ages ranged from 42 53 years, had atrophic edentulous maxillae posterior region. To determine status, patients were investigated utilizing intraoral photographs CBCT series. Closed Sinus Lifting done compared DIVA on who randomly separated into two equal groups. predicted research variables intraoperative primary stability level of lift. main outcome factors secondary Osseointegration (ISQ) amount bone height gain. Results: Before surgery, Balloon groups mean heights 5.8 ± 0.67mm 6.8 0.86mm , which increased significantly 12.8± 0.53 10.8± 0.67 after 6 months postoperatively. ISQ for 39.0± 2.16 40.0±2.16 preoperatively, respectively, 71.7±1.60 70.4±1.27 nine postoperatively was higher at 3 group.
