  1. 1. Functional appliance treatment and stability in Class II/1 malocclusion, and masticatory muscle characteristics

    Författare :Gregory Antonarakis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Class II malocclusion; functional appliances; masticatory muscles; stability; ultrasonography; bite force;

    Sammanfattning : Aims: To evaluate the short-term antero-posterior effects on Class II division 1 malocclusion in growing children using functional appliances, and investigate whether the functional capacity of the masticatory musculature can be used as a predictive variable in determining the treatment and post-treatment effects following functional appliance treatment. Material and Methods: Firstly, a literature search was carried out identifying prospective clinical trials on the treatment of Class II malocclusion using functional appliances or/and headgear in growing children.

  2. 2. 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

    Författare :Anna-Paulina Wiedel; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bettfel; Tandreglering; Ortodonti; Orthodontics; Malocclusion;

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

  3. 3. Palatal plate therapy in children with Down syndrome : a longitudinal study of effects on oral motor function

    Författare :Kerstin Carlstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Articulation; children; communication preference; craniofacial growth; Down syndrome; dental maturity; functional appliances; growth hormone; muscle tone; oral dysfunction; tonsils; video registration;

    Sammanfattning : The aim of this thesis was to investigate the effect of palatal plate therapy on the oral motor function children with Down syndrome (DS) during 4 years by comparing the baseline values of the treatment group with those of a control group (CG). The effects of palatal plate therapy on speech production errors and communicative preference after 4 years of treatment were also studied and articulation was analyzed. LÄS MER

  4. 4. Comparative in vivo and in vitro studies on the biomechanics of maxillary partial dentures. A methodological and experimental study

    Författare :Cláudio Pinheiro Fernandes; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stomatology; biomechanics; Bite force; conical crowns; denture design; in vitro; in vivo; photoelasticity; strain gauges; Odontology; stress analysis.; Odontologi;

    Sammanfattning : Biomechanical aspects are generally agreed to be significant, particularly during the planning of restorative treatments and the design of prosthetic appliances. However, comparative in vivo/in vitro studies show wide differences in the magnitudes and patterns of functional strains in prosthetic devices. LÄS MER

  5. 5. Dental and orthopedic effects of Bass and Herbst therapy for correction of severe class II division 1 malocclusions

    Författare :Jane Ömblus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Orthodontics Class 11 malocclusion; skeletal changes dental changes functionalappliance maturity treatment evaluation.;

    Sammanfattning : Functional appliance therapy to correct Class II division I malocclusions has been a subject of debate throughout this century. The aims of this thesis, based on six publications, were to evaluate the dental and orthopedic effects of Bass appliance therapy in relation to treatment intensity, age, and somatic maturation, and to compare initial and post-treatment effects of Herbst and Bass therapy.
