Three-dimensional assessment of upper lip positional changes according to simulated maxillary anterior tooth movements by white light scanning
OBJECTIVE Esthetic improvements during orthodontic treatment are achieved by changes in positions of the lips and surrounding soft tissues. Facial soft-tissue movement has already been two-dimensionally evaluated by cephalometry. In this study, we aimed to three-dimensionally assess positional changes of the adult upper lip according to simulated maxillary anterior tooth movements by white ligh...
متن کاملUpper lip changes correlated to maxillary incisor retraction--a metallic implant study.
The soft tissue changes after the extraction of maxillary first premolars and subsequent anterior tooth retraction were evaluated for 16 Class II, division 1 patients. Pre- and posttreatment lateral head cephalograms were evaluated using superimpositions on Björk-type metallic implants in the maxilla. The patient sample was divided into group I patients, those who did exhibit lip seal at rest i...
متن کامل[Three dimensional analysis of CT image on naso-maxillary complex in cleft lip and palate patients].
This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...
متن کاملA three-dimensional reconstruction of the rods in rat maxillary incisor enamel.
A three-dimensional reconstruction of the rod profiles seen in inner and outer rat incisor enamel was made from serial 1 μ cross sections of a decalcified upper incisor. The enamel rod was found to be an elongated structure which travelled incisally relative to its origin and ran continuously from the dentino-enamel junction to the enamel surface. The rod was divisible into an inner and outer e...
متن کاملLateral incisor agenesis predicts maxillary hypoplasia and Le Fort I advancement surgery in cleft patients.
BACKGROUND Severe maxillary hypoplasia in cleft patients is caused by a combination of pathogenic and iatrogenic factors. In this work, the authors investigated anatomical deficiencies in dentition for predicting Le Fort I maxillary advancement surgery for severe maxillary hypoplasia in cleft patients. METHODS Cleft lip-cleft palate and cleft palate patients older than 14 years of age were re...
