摘要: In this study texture differentiation associated to bone regeneration properties, around loaded oral implants immersed Platelets Rich Plasma (PRP), was investigated in panoramic radiographs. The bone-to-implant contact region analyzed a follow up clinical sample of 30 digitized radiographs, 15 corresponding implant loading (Class I) and after an 8 month period II). This sampled by circular Regions Interest (ROIs) resulting from specifically designed segmentation stage 518 ROIs (254 Class I 264 class From each ROI, 42 textural features were extracted, subjected statistical analysis order evaluate osseo integration implants. A subset 6 features, selected with stepwise discriminant method, achieved Area Under Curve (AUC) values greater than 0.73, indicating that these are capable capturing temporal attributed properties the region.
