What Do We Know Beyond Reliability in Voxel-Based Registration? Validation of the Accuracy of Regional Voxel-Based Registration (R-VBR) Techniques for Orthognathic Surgery Analysis

Michael D. Han et al.

Summary: This study validates the accuracy of regional voxel-based registration (RVBR) techniques used for postoperative orthognathic surgical analysis. The results show that RVBR has excellent accuracy in rotational measurements.

Evaluation of long-term hard tissue relapse following surgical-orthodontic treatment in skeletal class II patients: A systematic review and meta-analysis

L. Gaitan-Romero et al.

Summary: This study evaluated the long-term hard tissue stability and relapse factors following surgical-orthodontic treatment in skeletal class II patients. The findings revealed multiple intrinsic and extrinsic factors affecting long-term stability, but the outcomes of the meta-analysis are limited due to data heterogeneity and inconsistent evaluation methods. Further high-quality studies utilizing standardized three-dimensional methodologies are needed to improve the level of evidence.

Validation of the OrthoGnathicAnalyser 2.0-3D accuracy assessment tool for bimaxillary surgery and genioplasty

Frank Baan et al.

Summary: Orthognathic surgery is commonly performed to correct dentofacial deformities, and virtual treatment planning is essential in preparation. The OrthoGnathicAnalyser 2.0 tool allows for quantifying the accuracy of orthognathic surgery, specifically assessing osseous chin accuracy. The study confirms the high reproducibility of OrthoGnathicAnalyser 2.0 in quantifying skeletal movements between two (CB)CT scans.

Long-term stability of isolated advancement genioplasty, and influence of associated risk factors: A systematic review

E. Janssens et al.

Summary: Isolated advancement genioplasty was found to be a predictable and stable orthognathic procedure in the sagittal plane at both soft and hard tissue levels, with the average horizontal hard tissue relapse at pogonion varying from 0.1 to 2.1 mm and soft tissue relapse ranging from 0.3 to 2.9 mm after 1 year, showing minimal association with the fixation method or the amount of surgical advancement.

Three dimensional assessment of segmented Le Fort I osteotomy planning and follow-up: A validation study

Oliver da Costa et al.

Summary: The study developed and validated a 3D semi-automatic, voxel-based registration assessment protocol to evaluate planning accuracy and stability of segmented Le Fort I osteotomy with individualization of the maxillary segments. The results showed high reliability with only a small margin of error, indicating the protocol's potential for future improvement in the surgical procedure.
