動的治療後,咬合の安定をみたhigh angle caseの一治験例 An Orthodontic Case Report for High Angle Case Which Has Good Retention Stability 山川, 俊治 戸苅, 惇毅 high angle case facial axis Jarabak analysis application/pdf High angle case is said to be unstable in retention if mandibular plane is opened during treatment. Molars have a tendency to overerupt easily and growth direction will be changed to downward creating longer vertical dimension. Therefore, mandibular opening is a major concern for this kind of facial pattern. This present case shows high mandibular plane and long anterior vertical height, with a more prominent chin than that of a female of the same age. Four first premolars were extracted to correct crowding and control vertical dimension. Results show good stable occlusion and nice esthetic profile. Normal orofacial functions have been maintained during the four years retention period. Vertical dimension control is suggested to be a critical point to achieve a stable condition for high angle case in orthodontic treatment. 松本歯科大学学会 1992-12-31 jpn journal article VoR https://mdu.repo.nii.ac.jp/records/1005 AN00232590 0385-1613 松本歯学 18 3 316 325 https://mdu.repo.nii.ac.jp/record/1005/files/matsumoto_shigaku_18-03-11.pdf application/pdf 1.7 MB 2012-05-24
