Objective To observe therapeutic effect of MRC appliance for class Ⅲ incisor relationship in mixed dentition.Methods Selecting 40 cases of class Ⅲ incisor relationship in mixed dentition in our hospital,all the patients were treated with MRC appliance. After one year's treatment,comparing the pre-...
This case report describes a 14 year old female patient, with pseudo-Class III incisorrelationship on a mild Class III skeletal base with ankyloglossia. It highlights therelationship of an unfavorable soft tissue environment exerted by "tongue tie" andgenetic factors proposed by the prese...
3. Treatment with chin cup or functional appliances can correct a Class III incisor relationship, but any orthopedic changes are likely to be minimal with these appliances. 4. Optimal timing for interceptive treatment with face- mask is in the deciduous or early mixed dentition stage. Early ...
Severe Class II division 2 is a difficult malocclusion to treat properly, especially when lower incisors contact palatal mucosa. Only fixed appliance therapy can achieve worthwhile and lasting improvement of the incisor relationship in this situation. In less severe cases, it may be possible to achie...
However, an antero-posterior increase in the size of the mandibular corpus was most apparent in the incisor alveolus region (鈮�35 per cent increase in size). For shape-change, the Korean and European-American mandibular configurations were fairly isotropic except in the symphyseal and incisor...
Evaluation of root resorption in the lower incisors after orthodontic treatment of skeletal Class III malocclusion by three-dimensional volumetric measurem... OBJECTIVES\nTo investigate the volumetric changes of the lower incisor roots in skeletal Class III orthodontic patients with anterior crossbite after...
The treatment objectives were to (1) correct the anterior edge-to-edge occlusion and establish a normal incisor relationship, (2) achieve Class I molar and canine relationships by uprighting and distalizing the mandibular posterior teeth, (3) resolve the crowding in the mandibular arch, (4) co...
two or more of the lower incisal edges occlude anterior to the cingulum plateau of the upper incisors (British Standards Institute incisor classification). The overjet (OJ) is reduced or reversed and there may be an anterior mandibular displacement. The molar relationship is often Class III. ...
(-5°< ANB<0°, APDI>89°, Wits<-1 mm, SNA ≤ 80°); maxillary mild-moderate crowded; crown-to-root ratios of maxillary central incisor<1; without severe facial asymmetry (>5 mm of lower midline deviation from the facial midline); dental Class I relationship at the end of ...
