• mandible
  • Skeletal Class III: Over growth of the mandible with obtuse mandibular angle. (stomaeduj.com)
  • 2 ] Skeletal Class II jaw relation may be due to a prognathic maxilla, retrognathic mandible, or a combination of both. (pubmedcentralcanada.ca)
  • The anterior inclined plane guides the mandible forward into a class I relationship as the patient closes. (ommegaonline.org)
  • An anterior crossbite due to skeletal reasons will involve a deficient maxilla and a more hyperplastic or overgrown mandible. (wikipedia.org)
  • Unilateral crossbites can present with following features in a child Lower midline deviation to the crossbite side Class 2 Subdivision relationships Temporomandibular disorders A child with posterior crossbite should be treated immediately if the child shifts his mandible on closing which is often seen in a unilateral crossbite as mentioned above. (wikipedia.org)
  • Therefore, the mandible is brought forward by 6-7mm and it is opened 3-4mm. (wikipedia.org)
  • This involves prevention of any eruption of posterior molars because their eruption would lead to mandible moving downwards and backwards which would cause worsening of a Class II malocclusion and increase in the lower facial height. (wikipedia.org)
  • jaws
  • 2. Material and Method Salzmann in 1950 was the first to classify the underlying skeletal structure, and he stated that Skeletal Class I: Purely dental with the bones of the face and jaws being in harmony with one another and with the rest of the head. (stomaeduj.com)
  • Malocclusions may be coupled with skeletal disharmony of the face, where the relations between the upper and lower jaws are not appropriate. (wikipedia.org)
  • occlusion
  • A major disadvantage of classifying malocclusions according to Angle's system is that it only takes into consideration the two-dimensional viewing along a spatial axis in the sagittal plane in the terminal occlusion, even though occlusion problems are, in principle, three-dimensional. (wikipedia.org)
  • anteroposterior
  • From their lateral cephalographs and panoramic radiographs, their anteroposterior skeletal features, the dental maturity and eruption rate were obtained of each group and data were analyzed to yield the results as follows: 1. (koreascience.or.kr)
  • headgear
  • In growing patients there are more options for treating skeletal discrepancies, either promoting or restricting growth using functional appliances, orthodontic headgear or a reverse pull facemask. (wikipedia.org)
  • Orthodontic headgear will usually consist of three major components: Facebow: first, the facebow (or J-Hooks) is fitted with a metal arch onto headgear tubes attached to the rear upper and lower molars. (wikipedia.org)
  • esthetic
  • Stable and successful results were obtained with a substantial improvement in facial profile, skeletal jaw relationship, and overall esthetic appearance of the patient. (pubmedcentralcanada.ca)
  • anchorage
  • Recently, researchers have tried to overcome this problem by designing new intraoral systems involving skeletal anchorage solutions. (springeropen.com)
  • In 2011, Fudalej and Antoszewska [[ 5 ]] conducted a systematic review of 12 relevant articles describing distalizing appliances reinforced with temporary skeletal anchorage devices in order to study their efficacy. (springeropen.com)
  • Extraoral anchorage can be divided into 3 different types. (wikipedia.org)
  • extractions
  • PowerScope provides the best results for Class II management, thus enables us to treat such cases by a nonextraction approach rather than contemplating extractions. (pubmedcentralcanada.ca)
  • tooth
  • In the current study, we investigated the involvement of the GSK-3β/β-catenin signaling pathway, which is critical for bone formation during tooth movement. (readbyqxmd.com)
  • We established a rat tooth movement model to test the hypothesis that orthodontic force may stimulate bone formation at the tension site of the moved tooth and promote the rate of tooth movement via regulation of the GSK-3β/β-catenin signaling pathway. (readbyqxmd.com)
  • Fixed orthodontic appliances aid tooth movement, and are used when a 3-D movement of the tooth is required in the mouth and multiple tooth movement is necessary. (wikipedia.org)
  • classification
  • Thus, numerous attempts have been made to modify the Angle system or to replace it completely with a more efficient one, but Angle's classification continues to prevail mainly because of its simplicity and clarity. (wikipedia.org)
  • Alternative systems have been suggested by, among others, Simon (1930, the first three-dimensional classification system), Jacob A. Salzmann (1950, with a classification system based on skeletal structures) and James L. Ackerman and William R. Proffit (1969). (wikipedia.org)
  • soft tissue
  • This study aimed to (1) analyze the relationships between mandibular symphysis characteristics (height, prominence, inclination, concavity, and convexity) and facial pattern, skeletal class, lower incisor position, and sex, and (2) determine the associations between the symphysis soft tissue dimensions and the underlying osseous structures. (springer.com)
  • The shape of the symphysis soft tissue is not directly correlated with the underlying skeletal structures. (springer.com)
