“…TFA 3D cephalometry allows the clinician to locate where the major or minor skeletal discrepancies are located with respect to ideal parameters and is also useful in the classification of the patient which helps to determine whether there is a class I skeletal intermaxillary relation [9]. The superimposition method is highly intuitive but does not provide information on the quantity and location of osteotomic movement.…”

Background: Cephalometry is fundamental in diagnosis, analysis, and planning of orthodontic-surgical treatment as it reveals skeletal relationship between the upper and lower jaw as well as facial aesthetic parameters. Nevertheless, 3D cephalometry has still not become the exam of choice in orthognathic treatment even though today CBCT (Cone Beam Computed Tomography) is routinely used in other branches of dentistry. Methods: In a sample of 13 patients undergoing bimaxillary orthognathic surgery a chin-vertex CBCT exam was prescribed prior to orthodontic treatment (OT) and 12 months after surgery (T1). The DICOM files uploaded to MaterialiseSimplant Ortho software pro 2.1 (Materialise Co., Leuven, Belgium) were analyzed following the multiplane 3D Total Face cephalometry protocol (TFA). Results: Results comparing pre-op and post-op TFA 3D cephalometry, were then evaluated considering reference values reported in literature. The CBCT, carried out pre- and post-surgery, were subsequently analyzed employing the superimposition method using cranial base as reference. The aim of this study is to evaluate the advantages and disadvantages of the two methods in orthognathic surgery. Conclusions: Multiplane 3D TFA allows the clinician to locate where major or minor skeletal discrepancies are found with respect to ideal parameters and is also useful in classifying skeletal intermaxillary relation. The superimposition method is highly intuitive but does not provide information on the quantity and location of osteotomic movement.

“…Before tracing, the CBCT images were orientated according to three reference planes identified by selecting three points on the most external slice of the CBCT scan, respectively, for every single view (coronal, axial, and sagittal), as previously done by Perrotti et al [ 6 ] ( Figure 4 ).…”

“…Furthermore, Farronato et al [ 1 ] concluded that the information provided by the graphical representation facilitated orthodontic diagnosis making it more reliable and repeatable. Perrotti et al [ 6 ] proposed a novel 3D cephalometric analysis with relative normal values of reference.…”

“3D Counterpart Analysis”: A Novel Method for Enlow’s Counterpart Analysis on CBCT

The aim of this study was to propose a novel 3D Enlow’s counterpart analysis traced on cone-beam computed tomography (CBCT) images. Eighteen CBCT images of skeletal Class I (ANB = 2° ± 2°) subjects (12 males and 6 females, aged from 9 to 19 years) with no history of previous orthodontic treatment were selected. For each subject, a 2D Enlow’s counterpart analysis was performed on lateral cephalograms extracted from the CBCT images. The following structures were identified: mandibular ramus, middle cranial floor, maxillary skeletal arch, mandibular skeletal arch, maxillary dento-alveolar arch, mandibular dento-alveolar arch. The differences between each part and its relative counterpart obtained from the 2D analysis were than compared with those obtained from a 3D analysis traced on the CBCT images. A Student’s t-test did not show any statistical significant difference between the 2D and 3D measurements. The landmarks proposed by this study identified the cranio-facial structures on the 3D images in a way that could be superimposed on those described by Enlow in his analysis performed on 2D lateral cephalograms.

“…A comparative study of multiple combination medications shows that the quadruple combination with LHQW can be the first choice for the treatment of patients in critical condition [157] . In detail, Rhein, forsythoside A, forsythoside I, neochlorogenic acid and its isomers may be the effective active ingredients of LHQW against SARS-CoV-2 [158] . A retrospective analysis of JHQG treatment promotes the absorption of pneumonia permeate with a higher 7-day viral clearance rate compared with the control group [159] .…”
