  1. 1. Correction of unilateral posterior crossbite in the mixed dentition : studies of treatment effects, stability and cost-effectiveness

    University dissertation from Department of Orthodontics, Faculty of Odontology, Malmö University

    Author : Sofia Petrén; Malmö University.; [2011]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; orthodontics; evidence-based orthodontics; early treatment; maxillary expansion; crossbite correction;

    Abstract : Unilateral posterior crossbite of dento-alveolar origin is a trans-verse discrepancy of the maxillo-mandibular relationship and is one of the most common malocclusions in the mixed dentition. If untreated, the crossbite and the abnormal lateral movement of the lower jaw may strain the orofacial structures, causing adverse ef-fects on the temporomandibular joints, the masticatory system and facial growth.

  2. 2. Orthodontically induced root resorption: a clinical and radiographic survey

    University dissertation from Göteborg : University of Gothenburg

    Author : Dimitrios Makedonas; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; root resorption; prediction; CBCT; Angle Class I; fixed appliance; six month; risk factors;

    Abstract : In 2005 the Swedish Council on Health Technology Assessment (SBU), in a systematic review, Malocclusions and Orthodontic Treatment in a Health Perspective, concluded that there were low or contradicted evidence for an association between orthodontic treatment and the risks for negative side effects. The aims of this study was to evaluate the perception of Greek and Swedish orthodontic practitioners view on orthodontically induced root resorption (OIRR), to investigate how root resorption is handled in a large orthodontic clinic and to prospectively study and correlate the prevalence and severity of root resorption seen after an initial treatment period and at the end of treatment, in a cohort of patients treated with fixed appliance.

  3. 3. Masticatory function and temporomandibular disorders in patients with dentofacial deformities : studies before and after orthodontic and orthognathic treatment

    University dissertation from Swedish Dental Journal

    Author : Cecilia Abrahamsson; Malmö University.; [2013]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; dentofacial deformities; orthognathic treatment; orthognathic surgery; orthodontics; stomathognathic physiology; temporomandibular disorders; masticatory function;

    Abstract : abstract About 30 % of individuals in the Swedish population will at some stage during life have treatment with orthodontic appliances. In more severe cases, when orthodontic treatment is not considered sufficient enough to correct the malocclusion, the orthodontic treatment is combined with orthognathic surgery. READ MORE

  4. 4. Fixed or removable appliance for early orthodontic treatment of functional anterior crossbite : evidence-based evaluations of success rate of interventions, treatment stability, cost-effectiveness and patients perceptions

    University dissertation from Malmö university, Faculty of Odontology

    Author : Anna-Paulina Wiedel; Malmö University.; [2015]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; Orthodontics; Malocclusion; Bettfel; Tandreglering; Ortodonti;

    Abstract : Anterior crossbite with functional shift also called pseudo Class III is a malocclusion in which the incisal edges of one or more maxillary incisors occlude with the incisal edges of the mandibular incisors in centric relationship: the mandible and mandibular incisors are then guided anteriorly in central occlusion resulting in an anterior crossbite.Early correction, at the mixed dentition stage, is recommended, in order to avoid a compromising dentofacial condition which could result in the development of a true Class III malocclusion and temporomandibular symptoms.

  5. 5. Distal movement of maxillary molars. Studies of efficiency and timing of treatment

    University dissertation from Malmö University

    Author : Ingela Karlsson; Malmö University.; [2008]
    Keywords : ODONTOLOGY; ODONTOLOGI; Medicine; Orthodontics; Distal molar movement;

    Abstract : Maxillary molar distalization is a frequently used treatment method in cases with crowding associated with dental Class II molar relationship or Class I skeletal relationship. Despite the fact that several studies have been published concerning the treatment outcome of different appliances for distal movement of maxillary molars, it is still difficult to interpret the results and evidence presented in these studies because a variety of study designs, sample sizes and research approaches exists.
