- Orofaciala funktionsstörningar och smärta är en sammanfattning av kliniska problem och sjukdomar som involverar bett, käkar, tuggmuskulatur, käkleder och omgivande strukturer. Orsakerna är oftast multifaktoriella för de barn, ungdomar och vuxna som drabbas.

- OBJECTIVE: To document and analyze factors involved in decision-making by orthodontists in managing disturbances of eruption of maxillary canines. MATERIAL AND METHODS: The participants comprised orthodontic specialists and active members of the Swedish Orthodontic Society. Those selected for the study sample were under 65 years of age or younger and had been treating orthodontic patients for at least 1 year as a specialist. Three typical cases were presented for treatment proposals. The case notes, including radiographs and specific background data, were sent to the 182 selected orthodontists. The orthodontists were also requested to complete a questionnaire about practice profile, comprising eight questions. RESULTS: The response rate was 86.3%; yielding 157 participants (mean age 53.8 years, SD 8.12). Analysis disclosed no differences between responders and nonresponders regarding age, gender, and years of specialist practice. For treatment plans based on panoramic radiographs, intraoral radiographs, and status and anamnesis, there was general consensus. However, when supplementary information from computer tomography (CT) was provided, disclosing root resorption half-way to the pulp or more on the lateral incisor, the orthodontists' treatment proposals varied. Gender, age, and practice profile of the orthodontists had little association with the decision-making. CONCLUSIONS: Supplementary CT information led to variations in decision-making with respect to treatment of eruption disturbances of maxillary canines. This lack of consensus among specialist orthodontists can have negative implications for patients.

- INTRODUCTION: Our aim in this investigation was to evaluate and compare orthodontic anchorage capacity of 4 anchorage systems during leveling/aligning and space closure after maxillary premolar extractions. METHODS: One hundred twenty patients (60 girls, 60 boys; mean age, 14.3 years; SD 1.73) were recruited and randomized into 4 anchorage systems: Onplant (Nobel Biocare, Gothenburg, Sweden), Orthosystem implant (Institut Straumann AG, Basel, Switzerland), headgear, and transpalatal bar. The main outcome measures were cephalometric analysis of maxillary first molar and incisor movement, sagittal growth changes of the maxilla, and treatment time. The results were also analyzed on an intention-to-treat basis. RESULTS: The maxillary molars were stable during the leveling/aligning in the Onplant, Orthosystem implant, and headgear groups, but the transpalatal bar group had anchorage loss (mean, 1.0 mm; P <.001). During the space-closure phase, the molars were still stable in the Onplant and Orthosystem groups, whereas the headgear and transpalatal bar groups had anchorage loss (means, 1.6 and 1.0 mm, respectively; P <.001). Thus, the Onplant and the Orthosystem implant groups had significantly higher success rates for anchorage than did the headgear and transpalatal bar groups. Compared with the Orthosystem implant, there were more technical problems with the Onplant. CONCLUSIONS: If maximum anchorage is required, the Orthosystem implant is the system of choice.

Malocclusion traits and orthodontic treatment needs in prematurely born children

- OBJECTIVE: To evaluate if prematurely born children have higher prevalence of malocclusion traits and greater orthodontic treatment need than matched full-term born controls. MATERIALS AND METHODS: Seventy-three preterm children were selected from the Medical Birth Register and divided into two subgroups according to their gestational age. One group consisted of 37 very preterm children (VPT), born in gestational week 29-32, and the other of 36 extremely preterm children (EPT), born before the 29th gestational week. The subjects were compared with a control group of 41 full-term children, who were matched for sex, age, and nationality. Data from clinical examinations, study casts, and panoramic radiographs were used to determine malocclusion traits. The dental health component of the index of orthodontic treatment need (IOTN) was used to rank the treatment need. RESULTS: Two or more malocclusion traits occurred significantly more often among EPT (83.3%) and VPT children (73.0%), compared with the full-term children (51.2%). Significantly higher prevalence of deep bites and was found in EPT and VPT groups compared with the full-term control group. Deep bite was the most common malocclusion trait in the EPT and VPT group. Higher orthodontic treatment need was found for the preterm children but no differences in prevalence of malocclusion traits and treatment need were found between VPT and EPT children. CONCLUSION: The clinician should be aware of the potential for a higher number of malocclusion traits and greater orthodontic treatment need in prematurely born children compared with full-term children.

- INTRODUCTION: From an evidence-based point of view, correction of posterior crossbite is not sufficiently evaluated. Thus, the aims of this study were to compare and evaluate the effectiveness of different treatment strategies to correct unilateral posterior crossbite in the mixed dentition by using the randomized clinical trial methodology with an untreated control group. METHODS: Sixty patients participated in the study. All met the following inclusion criteria: mixed dentition, unilateral posterior crossbite, no sucking habits, and no previous orthodontic treatment. The patients were randomized into 4 groups: quad-helix, expansion plate, composite onlay, and untreated control. The success rates, amounts of maxillary and mandibular expansion, and treatment times were registered. RESULTS: The quad-helix appliance was superior to the expansion plate in success rate and treatment time. Treatment with the expansion plate was unsuccessful in one third of the subjects. Crossbite correction with composite onlay in the mixed dentition was ineffective, and spontaneous correction in the mixed dentition did not occur. CONCLUSIONS: If unilateral posterior crossbite is planned to be corrected in the mixed dentition, this study clearly confirmed that treatment with the quad-helix is an appropriate and successful method.
