Abstrakt: Objectives: To assess the safety and accuracy of static computer assisted corticotomy surgery (sCACS) in comparison with freehand piezocision.
Materials and Methods: A randomized in vitro study was conducted. A total of 260 interradicular corticotomies were performed in 20 identical printed models. sCACS was performed in half of the models, while the rest underwent freehand localized decortication. Accuracy was measured in the three spatial axes by overlapping the digital planning with a previous cone-beam computed tomography (CBCT) scan of the patient and a postoperative CBCT of the models. Safety was determined as the number of damaged root surfaces. Descriptive and bivariate analyses were performed.
Results: Freehand corticotomies increased the likelihood of iatrogenic root damage 2.21-fold (95%CI: 1.30 to 3.77; p = 0.004). Both groups showed some degree of deviation compared to digital planning. Nevertheless, the accuracy of sCACS was significantly greater in sagittal (B = -0.21 mm, 95%CI: -0.29 to -0.12; p < 0.001), axial (B = -0.32 mm, 95%CI: -0.48 to -0.18; p < 0.001) and angular deviation (B = -2.02º; 95%CI: -2.37 to -1.66; p < 0.001) compared to freehand surgery, with the exception of depth.
Conclusions: The precision and safety of sCACS are greater than the freehand technique.
Clinical Relevance: Corticotomies are performed in crowded areas where there is usually space limitation. Clinicians should consider the systematic use of surgical guides, since minimal deviations can cause iatrogenic root damage in areas where malocclusions are present.
