Our new method is capable of automatically articulating the digital dental models to the clinically desired final occlusion, including several partial edentulous cases. The entire process of our method is completed within 3 min. The clinical contribution of this method is significant. It allows doctors to eliminate the use of stone dental models and…

This systematic review and meta-analysis suggests that CAS is shortening the operative time and ischemia time for mandibular/maxillary reconstruction. It also leads to a reduction in hospitalization. Additionally, CAS seems to shorten the preoperative planning time for orthognathic surgery. #CAS #time #computerorthognathic #양악 Time matters – Differences between computer-assisted surgery and conventional planning in…

It also showed that the two techniques consumed an equal amount of time, but that the 2-dimensional technique had lower financial costs, and the 3-dimensional technique a larger dose of radiation.

#orthognathic #surgery #interferencesdistal #segmentproximal The results indicated that clockwise rotation of the mandible was the mandibular movement most prone to segment interference. Furthermore, virtual planning was sensitive (100%) but had low specificity (51.6%) in predicting proximal and distal segment interferences. This low specificity was due to the software-based automated design of the mandibular osteotomy,…

After USSRO surgery, condylar surface changes occurred at the deviated side of the TMJ, and the dental midline deviation was closely related to the changes of condylar surface morphology. https://head-face-med.biomedcentral.com/articles/10.1186/s13005-019-0202-z 이 글은 네이버 블로그에서 가져온 글입니다. 원문: blog.naver.com/surgeon

In conclusion, differences between original Le Fort I osteotomy and maxillary step osteotomy were observed at the frontal points of the mandible; however, they were not clinically significant. It may be suggested that there is no significant difference in skeletal stability at 1 year after the two procedures. Skeletal stability after maxillary step osteotomy…

Postoperatively the condyles moved outwards, backwards, and downwards in both groups of patients. The condylar position changed immediately after mandibular advancement and setback, and persisted in the long term. Larger condyles tended to have fewer positional changes. This study suggests that stability may be related to the size of the condyle, and that because…

OGS for obstructive sleep apnea (Semin Orthod 2019; 25:218–229) Stanford protocol Phase 1 surgery consisted of multiple procedures to address obstructive areas all along the upper respiratory tract; nasal and palatal procedures for the nasopharynx, genio- glossus advancement procedures for oropharynx, and hyoid suspension procedures for hypophar- ynx and Phase 2 surgery was maxillomandibular…

Unrecognized condylar sag with malpositioned condylar segments in the 3-dimensional (3D) plane will result in unacceptable malocclusion, poor esthetic outcomes, and masticatory and TMJ functional impairment.2 The ideal condylar position in the glenoid fossae is critical for condylar function and for the accuracy and stability of postoperative occlusion and TMJ function. Proximal ramus position…

The accuracy of surgical treatment of severe malocclusions is dependent on three main stages: preoperative planning; transfer of planning to operation (surgical template); and surgical precision or relapse. This might be available after further development of the cone-beam CT technique with a reduced dose of radiation and better imaging of the soft tissues, or…
