Định nghĩa ảo của điểm mốc cheilion Bước 1: Xác định cheilionl cheilionr và điểm mốc trên quan điểm phía trước của các đại diện 3-D mô diện tích bề mặt mềm (Hình 5,56). | 5.1 Definition of 3-D Cephalometric Soft Tissue Landmarks CHAPTER 5 Cheilion chr chl Fig. 5.56. Cheilionr and cheilionl. Frontal view 3-D CT patient K.C. Definition of the cheilion Landmarks Cheilion ch is the point located at each labial commissure. Virtual Definition of the cheilion Landmarks Step 1 Define the cheilionr and cheilionl landmarks on the frontal view of the 3-D soft tissue surface representation Fig. 5.56 . 215 3-D Cephalometric Soft Tissue Landmarks Labiale or labrale inferius li Fig. 5.57. Labiale inferius. Profile view right 3-D CT patient K.C. Fig. 5.58. Labiale inferius. Profile view left 3-D CT patient K.C. Fig. 5.59. Labiale inferius. Submental view 3-D CT patient K.C. Definition of the labiale inferius Landmark Labiale inferius li is the midpoint of the vermilion line of the lower lip. Virtual Definition of the labiale inferius Landmark Step 1 Define labiale inferius on the right profile view of the 3-D soft tissue surface representation Fig. 5.57 and verify its position on the left profile view Fig. 5.58 . The position of the labiale inferius landmark can also be verified on the virtual lateral cephalogram Figs. 5.76 5.77 . Step 2 Verify the midline position of the labiale inferius landmark on the submental view of the 3-D soft tissue surface representation Fig. 5.59 . 216 5.1 Definition of 3-D Cephalometric Soft Tissue Landmarks CHAPTER 5 Soft tissue gonion gor gO Fig. 5.60.
