Maxillary incisor retraction: evaluation of different mechanisms.
OBJECTIVE To mechanically evaluate different systems used for incisors retraction. METHODS Three different methods for incisors retraction using 0.019 x 0.025-in stainless steel wire were evaluated. The samples were divided into three groups: Group A (retraction arch with 7-mm high vertical hooks); Group G3 (elastic chain attached to the mini-implant and to the 3-mm stainless steel hook welde...
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 کاملIncidence, Heritability of Maxillary Lateral Incisor Agenesis Familial Aggregation of Maxillary Lateral Incisor Agenesis
Background: A common problem that requires orthodontic intervention is maxillary lateral incisor agenesis. A common treatment for this problem is to open space for a maxillary lateral incisor implant. However, that treatment is expensive. Often, parents with this problem wonder if their children will also have this anomaly. Objective: To determine the relative risk of a parent with maxillary la...
متن کاملMaxillary Lateral Incisor Agenesis (MLIA)
In the permanent dentition, the type of congenital missing teeth varies from author to author and the demographic and geographic profiles. In Europeans, the mandibular second premolar is the most frequently absent tooth, followed by the maxillary lateral incisor and the maxillary second premolars (Bergstrom, 1977; Rolling, 1980; O'Dowling & McNamara, 1990; Aasheim & Øgaard, 1993; Nordgarden et ...
متن کاملThe primary Maxillary Central Incisor in the Solitary Median Maxillary Central Incisor syndrome.
AIM Solitary Median Maxillary Central Incisor (SMMCI) is a developmental anomaly in the permanent dentition with one single central incisor in the maxilla, positioned exactly in the midline. This condition has been associated with extra- and intraoral malformations in the frontonasal segment of the cranium and face. It is not known whether the centrally located permanent incisor is always pr...
