Patient Perception and Radiographic Assessment of Sinus Lifting Procedure using Densah Bur versus Osteotome-mediated sinus lifting: A Randomized Clinical Trial

Abstract

Aim: This study aimed to evaluate the patient perception towards osteotome and densah burs in sinus lifting procedures and to assess the new bone generated using CBCT at 6 months post-operatively. The study hypothesis was that densah bur would show comparable results to osteotome-mediated sinus lifting. Subjects and methods: Ten patients were enrolled in the study with atrophied maxillary posterior edentulous area that required rehabilitation with implants and sinus membrane elevation. Sinus membrane was elevated with two techniques, Osteotome and Densah bur sinus lifting procedures. Clinical (sinus perforation, post-operative swelling, and headache/vertigo) and radiographic parameters (residual bone height (RBH) and endo-sinus bone gain (ESBG)) were assessed. Result: In both groups, new bone levels were higher in comparison to initial levels with statistical significant difference. Densah bur showed higher mean ESBG than osteotome group with values 1.8 ± 0.4 and 1.4 ± 0.5 respectively (p = 0.21). Post-operative complications comparison showed non-significant differences between both groups except for headache and vertigo. Conclusion:The protruded implants can act as tents and allow formation of blood clot with concomitant bone regeneration. Although the two techniques applied for drilling showed comparable radiographic results, however, they displayed differences in patient perception. According to this study, it can be concluded that osseodensification may surpass osteotome-lifting procedure when it comes to patient comfort and satisfaction.
