  1. 1. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

    Författare :Catharina Hagberg; []
    Nyckelord :Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

    Sammanfattning : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. LÄS MER

  3. 2. 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.

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

    Författare :Cecilia Abrahamsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dentofacial deformities; orthognathic treatment; orthognathic surgery; orthodontics; stomathognathic physiology; temporomandibular disorders; masticatory function;

    Sammanfattning : Ca 30 % av Sveriges befolkning genomgår någon gång i livet behandling med tandreglering. I de fall där bettavvikelsen är mer omfattande är enbart tandreglering inte tillräckligt för att uppnå ett bra bett. Istället kombinerar man tandregleringen med en kirurgisk förflyttning av käkarna s.k. LÄS MER

  5. 4. Context dependent adaptation of biting behavior in human

    Författare :Anders Johansson; Benoni Edin; Karl-Gunnar Westberg; Peter Svensson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EMG; bite force; human; mastication; muscles; jaw opening reflex; motor control; reflex modulation; periodontal attachment loss; periodontitis; fysiologi; Physiology;

    Sammanfattning : The focus of this thesis was to study an action that humans perform regularly, namely, to hold a morsel between the teeth and split it into smaller pieces. Three different issues related to this biting behavior were addressed:  (1) the effect of redu­c­ed perio­dontal tissues on food holding and splitting behavior; (2) the behavioral conse­quences of performing different bite tasks with different functional requirements, i.

  7. 5. Experimental tooth clenching : a model for studying mechanisms of muscle pain

    Författare :Andreas Dawson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tooth clenching; muscle pain; bruxism; Delphi technique; pain measurement; masticatory muscles; experimental pain; proprioceptive allodynia; temporomandibular disorders; serotonin; glutamate; masseter muscle; microdialysis;

    Sammanfattning : “I felt like I’d done three rounds with Mike Tyson…all becauseI was grinding my teeth in my sleep”, så beskrev en patient somintervjuades av Daily Mail i en artikel där det ökade problemet medöverbelastning i käkarna beskrevs, vilket kan leda till tandslitage,muskelsmärta, och frakturer på tandmaterial. Det personliga lidandet,och de ekonomiska kostnaderna för både individ och samhälle ärstort. LÄS MER
