Clinical Trial Summary

A successful implant surgery primarily relies on a prudent evaluation of oral anatomy and meticulous treatment planning. Additionally, of paramount importance that dictates the types of procedures, material selection and ultimately success of implant surgery is the quality and quantity of the edentulous ridge. Ultrasound imaging (US), another cross-sectional imaging modality, has been extensively used in the medical diagnostics field. The ability of ultrasound to image soft tissue-bone interface makes it particularly promising for studying bone ridge width and crestal bone topography. Therefore, this retrospective human study aimed to compare bone width measurements between US and CBCT. This study also investigated the possible correlation between the crestal bone surface quality imaged by US and CBCT.
