Molar intrusion using miniscrew palatal anchorage.
A 17-year-old female presented with the chief complaint of inability to bite properly. Clinical examination revealed a Class II, division 1 malocclusion with an anterior open bite and mild maxillary and mandibular tooth-sizearch-length discrepancies (Fig. 1, Table 1). The patient’s initial contact upon closure was between the maxillary and mandibular first molars, leading to a complex open bite...
متن کاملTreatment of Skeletal Anterior Open Bite Using Absolute Anchorage: A Case Report and Review
Background and purpose: Skeletal anchorage is a new aid for the correction of moderate anterior open bite. This study aimed at treating moderate anterior open bite using posterior intrusion via mini implants. In addition, a review of studies carried out on open bite correction using absolute anchorage was performed. Materials and methods: The following keywords were used: open bite, camouflag...
متن کاملSevere Anterior Open-Bite Case Treated Using Miniscrew Anchorage: A Case Report
Downward and backward rotation of the mandible and/or excessive eruption of posterior teeth often cause anterior open bite. Depending on the severity of the case, orthognathic surgery is often the treatment of choice due to the difficulty of establishing absolute anchorage of molars by using a traditional orthodontic mechanics. This article reports the successful treatment of a severe skeletal ...
متن کاملOptimizing Anterior En Masse Retraction with Miniscrew Anchorage
In severely protrusive patients, skeletal anchorage from miniscrew is often used to avoid anchorage loss with preferred miniscrew location near centre of resistance (Cres) of posterior teeth. Biomechanical requirement for directing retraction force towards Cres of posterior teeth demands the insertion of miniscrew in loose mucosa, where risk of infection and failure increases. In addition, unde...
متن کاملEffects of maxillary molar intrusion with zygomatic anchorage on the stomatognathic system in anterior open bite patients.
The aim of this study was to evaluate the effects of intrusion of the maxillary posterior teeth with zygomatic anchorage on the dentofacial system, on electromyographic (EMG) activity of the masticatory muscles, and on vibration of the temporomandibular joint. The study sample consisted of 19 subjects (13 females, 6 males) with a mean age of 17.7 years. Lateral cephalometric and posteroanterior...
