One year later, Lie et al., conducted a systematic review to evaluate efficacy of graftless maxillary sinus membrane elevation using the lateral window approach for implantation in the atrophic maxilla. It showed a high implant survival rate in non-grafted maxillary sinus lifts and conventional sinus lifts using augmentation materials and there was no significant difference in the ISQ values between both procedures. However, further randomized clinical trials with long-term follow-up were recommended.",[27],"Sinus Elevation",[29,30,31],"dental implants","bone grafting","posterior maxilla","NOT_YET_RECRUITING","2025-04-15",{"date":35,"type":36},"2025-04-18","ACTUAL",{"date":38,"type":21},"2025-08-01",{"date":40,"type":21},"2026-02-01",{"name":42,"class":43},"Misr International University","OTHER",{"id":45,"slug":46,"hasResults":11,"nctId":47,"briefTitle":48,"officialTitle":49,"acronym":4,"eligibilityCriteria":50,"healthyVolunteers":16,"sex":17,"minAge":51,"maxAge":52,"enrollmentInfo":53,"targetDuration":4,"studyType":22,"phases":55,"briefSummary":56,"conditions":57,"keywords":4,"overallStatus":60,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":64,"completionDateStruct":66,"leadSponsor":68,"locationsCount":70},"100467083","effect-of-multiple-perforations-of-the-sinus-floor-on-bone-formation-after-sinus-floor-elevation-100467083","NCT05362136","Effect of Multiple Perforations of the Sinus Floor on Bone Formation After Sinus Floor Elevation","Assessment of the Effect of Sinus Floor Perforation During Sinus Floor Elevation on Bone Formation Within the Augmentation Material","Inclusion Criteria:\n\n* in need of bilateral sinus floor elevation\n* residual alveolar ridge height 2-6mm\n* residual alveolar ridge width \\> 4mm\n\nExclusion Criteria:\n\n* uncontrolled periodontal disease\n* acute or chronic sinusitis","18 Years","120 Years",{"count":54,"type":21},12,[24],"The aim of the present study is to compare the rate of new bone formation after sinus floor elevation with or without perforation of the cortical sinus floor prior to insertion of augmentation material. Twelve patients requiring bilateral sinus floor elevation will be recruited for a pilot study in split-mouth design. On both sides a lateral window will be prepared and the sinus mucosa will be elevated. After this step, the sides are assigned as test or control side. While the control side is just filled with augmentation material, an additional step is performed for the test side, i.e., prior to inserting the augmentation material, the cortical bone layer of the sinus floor is perforated several times into the trabecular bone layer to improve the blood supply to the grafting material. Thereafter, both sides are left to healing for 4-6 months until implant installation. At timepoint of implant installation, a bone biopsy will be collected to allow histological assessment of the grafted area.",[27,58,59],"Dental Implant","Bone Formation","RECRUITING","2022-05-10",{"date":63,"type":36},"2022-05-11",{"date":65,"type":36},"2017-03-23",{"date":67,"type":21},"2027-12",{"name":69,"class":43},"Medical University of Vienna",1]
