BACKGROUND The aims of this study are to evaluate the lip morphology and change of lip commissure after mandibular setback surgery (MSS) for class III patients and analyze association between the amount of mandibular setback and change of lip morphology. METHODS The samples consisted of 14 class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalogram ...
Due to the lack of a standardized 3D cephalometric analysis methodology, 2D cephalograms synthesized from cone-beam computed tomography (CBCT) volumes are widely used for in dental CBCT systems. However, compared with conventional X-ray film based cephalograms, such synthetic image contrast and resolution, which impairs landmark identification. In addition, increased radiation dose applied acqu...
The cephalometric appraisal of mandibular incisor teeth in relation to the basal bone had its origin clinical outcomes that Tweed observed his treated cases. Although was an admirer Angle’s philosophy, failure achieve functional and aesthetic harmony some orthodontically cases prompted introspect methodology revisit records patients. Consequently, based on annotations aid, a Diagnostic Facial T...
This paper describes an identification method of a landmark in a roentgenographic cephalogram by employing the input-correlated wavelet neurons. For the purpose of improvement of identification precision, a novel pattern matching method, named "wavelet neuron matching (WNM)," is proposed in this paper. Furthermore, the "weighted window", which is proposed in this paper, enables us to consider t...
