Abstract

 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). Twenty
four 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.
