Restorative angle assessment and the influence on radiographic marginal bone levels Based on the restorative angle cut‐off (≤40°or >40°), the non‐parametric model for longitudinal data (Brunner‐Langer) revealed that from baseline to 5 years of follow‐up, the averaged marginal bone level (mesial/distal) depended on time ( p < .001) and angle (borderline significance; p = .056).
