Comparative Assessment of Ridge Expansion Using Densah Bur versus Rotary Bone Expanders after Ridge Splitting (Prospective Clinical Study)

Aim: This study aimed to evaluate and compare changes in alveolar ridge width using two techniques—Densah Bur and rotary bone expanders—after ridge splitting, assessed through cone beam computed tomography (CBCT).Subjects and methods: A prospective randomized clinical study included six patients (twelve sides) requiring implants. The split-mouth technique assigned one side of each patient to the Densah Bur (Group I) and the other to rotary bone expanders (Group II). Twentyfour implants were placed, with evaluations conducted at baseline and 6 months. Results: Both groups demonstrated significant increases in ridge width from baseline to 6 months (p < 0.001). Group I increased from 4.43 mm to 6.29 mm, and Group II from 4.25 mm to 6.24 mm. No statistically significant differences were noted between the two techniques (p > 0.05). Conclusion: Densah Burs and rotary bone expanders are effective for ridge splitting with simultaneous implant placement, yielding comparable results in ridge width augmentation.
