Abstract
Objectives : The aim of this study was to assess ridge expansion using Densah bur (Osseo densification) versus screw expanders in anterior maxilla. Methods : 16 patients with missed maxillary anterior teeth received 16 implants. Study group formed of 8 implants inserted using Densah burs osseodensification (OD) technique whereas Control group formed of 8 implants inserted using ridge expander’s procedure. All patients were assessed clinically and radiographically at implant insertion time, crown loading and 6th and 12th months after loading concerning implant stability using periotest, peri-implant pocket depth (PPD), modified sulcus bleeding Index (mSBI), degree of ridge expansion and marginal bone level (MBL). Results: Two implants were lost and the other 14 implants presented encouraging clinical and radiographic outcomes. eriotest evaluation revealed that all 14 implants were well osseointegrated and stable. There were no statistically significant differences in degree of ridge expansion, PPD, mSBI, and MBL between the two groups. Conclusion: Both Densah bur and screw expanders’ systems allow expansion of narrow maxillary ridge with no need to use bone grafts which reduce the time of treatment plan, diminishing the risk of cross-infection and decrease the cost for the patient.
