CBCT assessment of crestal bone changes and stability: Immediate versus delayed implant placement in grafted sites.

Alveolar ridge resorption after tooth extraction complicates optimal implant positioning and increases grafting requirements. Therefore, it is of interest to compare immediate versus delayed implant placement in 60 grafted extraction sites using Cone-beam computed tomography (CBCT) and resonance frequency analysis. Delayed placement preserved more buccal bone (-0.42±0.28 mm loss) than immediate placement (-0.89±0.34 mm, p<0.001), with comparable mesial/distal changes. Both achieved equivalent implant stability, integration and survival after 12 months. Delayed placement advances socket management by optimizing buccal contour preservation without compromising outcomes, informing timing decisions.
