- OBJECTIVE: To evaluate and compare perceived pain intensity and discomfort between the placement of two different orthodontic anchoring units designed for osseointegration and premolar extraction in adolescent patients. MATERIALS AND METHODS: A total of 120 adolescent patients (60 girls and 60 boys) were recruited and randomized into three groups. Group A underwent installation of an onplant, group B installation of an Orthosystem implant, and group C premolar extraction. Pain intensity and discomfort, analgesic consumption, limitations in daily activities, and functional jaw impairment were evaluated the first evening and one week after the intervention. RESULTS: Pain intensity following surgical installation of an onplant was comparable to the pain intensity experienced after premolar extraction, but there was significantly less pain after surgical installation of an Orthosystem implant compared to installation of an onplant (P = .002) or premolar extraction (P = .007). The protective, vacuum-formed stent caused great discomfort, even more discomfort than the surgical sites following installation of the onplant or the Orthosystem implant. CONCLUSION: The Orthosystem implant was better tolerated than the onplant in terms of pain intensity, discomfort, and analgesic consumption and was, therefore, the anchorage system of choice in a short-term perspective.

Forskningsöversikt (refereegranskat)abstract
- Objective: To evaluate the evidence on three-dimensional immediate effects of rapid maxillary expansion (RME) treatment on growing patients as assessed by computed tomography/cone beam computed tomography (CT/CBCT) imaging. Materials and Methods: The published literature was searched through the PubMed, Embase, and Cochrane Library electronic databases from January 1966 to December 2012. The inclusion criteria consisted of randomized controlled trials, prospective controlled studies, and prospective case-series. Two reviewers extracted the data independently and assessed the quality of the studies. Results: The search strategy resulted in 73 abstracts or full-text articles, of which 10 met the inclusion criteria. When treating posterior crossbites with a RME device, the existing evidence points out that the midpalatal suture opening is around 20%-50% of the total screw expansion. There seems to be no consistent evidence on whether the midpalatal sutural opening is parallel or triangular. The effect on the nasal cavity dimensions after RME seems to be apparent and indicates an enlargement between 17% and 33% of the total screw expansion. Circummaxillary sutures, particularly the zygomaticomaxillary and frontomaxillary sutures and also spheno-occipital synchondrosis, appear to be affected by the maxillary expansion. Overall, however, the changes were small and the evidence not conclusive. Conclusions: CT imaging proved to be a useful tool for assessment of treatment effects in all three dimensions. The majority of the articles were judged to be of low quality, and therefore, no evidence-based conclusions could to be drawn from these studies.

- 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.

Orthodontic anchorage : evidence-based evaluation of anchorage capacity and patients' perceptions
- 2007

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Orthodontic anchorage is the ability to resist unwanted reciprocalforces and reinforcement of anchorage by supplementary appliances,in or outside the mouth, is often needed to obtain successful results.In the last 10 years, interest in appliances that use implants has beengrowing.Successful orthodontic treatment demands effective methods andsystematic evaluation of different treatment approaches is thereforeessential. Several studies on the efficiency of various anchorage systemshave been published, but a critical appraisal or interpretationof evidence that systematically considers validity, results, and relevancehas not been made. Analysis of treatment modalities must alsoinclude patients’ perceptions and potential side-effects.The overall aim of this thesis was to evaluate a new anchoragetechnique that incorporates osseointegration and compare it withconventional methods concerning effects on tooth movements inadolescents and their acceptance and experience of the additionalsurgical procedures that osseointegration involves. The followinganchorage systems were analyzed: Onplant system, Orthosystemimplant, headgear and transpalatal bar.This thesis was based on four studies:Paper I systematically reviewed the efficiency of orthodontic anchoragesystems and interpreted the methodological quality of theselected studies from an evidence-based perspective. The literaturesearch spanned January 1966 – December 2004 and was later extendedto July 2007.

- The aim of this systematic review was to examine, in an evidence-based way, what kind of orthodontic anchorage systems/applications are evaluated and their effectiveness. A literature survey from the Pub Med and Cochrane databases covering the period from January 1966 to December 2004 was performed. Randomized controlled trials (RCT), prospective and retrospective controlled studies, and clinical trials comparing at least two anchorage situations were included. Two reviewers selected and extracted the data independently and also assessed the quality of the retrieved studies. The search strategy resulted in 494 articles, of which 14 met the inclusion criteria. Two main anchorage situations were identified: anchorage of molars during space closure after premolar extractions and anchorage loss in the incisor or premolar region (or both) during molar distalization. Because of contradictory results and the vast heterogeneity in study methods, the scientific evidence was too weak to evaluate anchorage efficiency during space closure. Intraoral molar distalization leads to anchorage loss in various amounts depending on the choice of distalization unit. Most of the studies had serious problems with small sample size, confounding factors, lack of method error analysis, and no blinding in measurements. To obtain reliable scientific evidence, controlled RCT's with sufficient sample sizes are needed to determine which anchorage system is the most effective in the respective anchorage situation. Further studies should also consider patient acceptance and cost analysis as well as implants as anchorage.

- The aim of this trial was to evaluate and compare perceived pain, discomfort, and jaw function impairment between orthodontic treatments combined with skeletal anchorage and treatment using conventional anchorage with headgear or transpalatal bar. A total of 120 adolescent patients in order to start orthodontic treatment were consecutively recruited and randomized into three groups with different anchorage. Group A underwent installation of a skeletal anchorage (Onplant or Orthosystem implant), group B received headgear, and group C a transpalatal bar. Questionnaires were used to assess pain intensity, discomfort, analgesic consumption, and jaw function impairment from baseline to the end of treatment. Pain scores overall peaked on day 2 and were almost back to baseline on day 7. The site with the highest pain scores during treatment was incisors in contact but with no differences between groups. Pain intensity from molars was significantly less in the skeletal anchorage group A compared to the transpalatal bar group C the first 4 days in treatment and with no sign differences compared to headgear. The results confirm that there were very few significant differences between patients' perceptions of skeletal and conventional anchorage systems during orthodontic treatment. Consequently, these new appliances were well accepted by the patients in a long time perspective and can thus be recommended.

- Objectives: To evaluate and compare perceived pain intensity, discomfort, and jaw function impairment during the first week with tooth-borne or tooth-bone-borne rapid maxillary expansion (RME) appliances. Materials and Methods: Fifty-four patients (28 girls and 26 boys) with a mean age of 9.8 years (SD 1.28 years) were randomized into two groups. Group A received a conventional hyrax appliance and group B a hybrid hyrax appliance anchored on mini-implants in the anterior palate. Questionnaires were used to assess pain intensity, discomfort, analgesic consumption, and jaw function impairment on the first and fourth days after RME appliance insertion. Results: Fifty patients answered both questionnaires. Overall median pain on the first day in treatment was 13.0 (range 0-82) and 3.5 (0-78) for groups A and B, respectively, with no significant differences in pain, discomfort, analgesic consumption, or functional jaw impairment between groups. Overall median pain on the fourth day was 9.0 (0-90) and 2.0 (0-71) for groups A and B, respectively, with no significant differences between groups. There were also no significant differences in pain levels within group A, while group B scored significantly lower concerning pain from molars and incisors and tensions from the jaw on day 4 than on the first day in treatment. There was a significant positive correlation between age and pain and discomfort on the fourth day in treatment. No correlations were found between sex and pain and discomfort, analgesic consumption, and jaw function impairment. Conclusions: Both tooth-borne and tooth-bone-borne RME were generally well tolerated by the patients during the first week of treatment.

- OBJECTIVE: To evaluate the reliability of a questionnaire that assessed the expectations and experiences of adolescent patients about orthodontic treatment. MATERIALS AND METHODS: The study included two groups of patients: 30 consecutive patients (19 girls and 11 boys, mean age 14.6 years, SD 2.3 years) naive to orthodontic treatment, and 30 consecutive adolescent patients (17 girls and 13 boys, mean age 15.1 years, SD 2.0 years) in active orthodontic treatment with fixed appliances in both jaws. A questionnaire comprising 46 items was developed, based upon focus group interviews and previous established questionnaires. The questionnaire covered the following domains: Treatment motivation; treatment expectations; pain and discomfort from teeth, jaws, and face; functional jaw impairment; and questionnaire validity. Internal consistency as well as temporal stability with the test-retest method was investigated. RESULTS: A majority of the questions exhibited acceptable test-retest reliability, and composite scores yielded excellent reliability for all domains. Internal consistency was acceptable and good face validity was found for all domains. CONCLUSION: The questionnaire can be recommended for use in the assessment of expectations and experiences of orthodontic treatment.

- Objectives:To examine factors associated with treatment outcome satisfaction in a group of adolescent patients.Materials andMethods:One hundred and twenty patients (60 girls and 60 boys; mean age, 14.3 years; standard deviation [SD], 1.73 years) were consecutively recruited. The inclusion criteria for all patients were as follows: adolescents with a permanent dentition in need of orthodontic treatment and a treatment plan involving extractions (two or four premolars) followed by fixed appliances in both jaws. Questionnaire 1, concerning treatment motivation and expectations, was assessed prior to treatment start. Questionnaire 2 was assessed after active treatment and included questions about satisfaction with treatment outcome, quality of care and attention, and perceived pain and discomfort during active treatment.Results:One hundred and ten patients completed the trial (54 boys and 56 girls; mean age, 16.9 years; SD, 1.78 years). Median values for satisfaction with treatment outcome were generally high. There was a clear correlation (P ≤ .001) between satisfaction with treatment outcome and patients' perception of how well they had been informed and cared for during treatment. Pain and discomfort during treatment also strongly affected treatment satisfaction. Sex, treatment time, and Peer Assessment Rating index pre- and posttreatment as well as expectations for future treatment showed no correlation with treatment satisfaction.Conclusions:Care and attention was the variable showing the highest correlation with satisfaction with treatment outcome. Patients' perceptions of pain and discomfort during treatment had an overall negative correlation with treatment satisfaction. Satisfaction with treatment outcome is a complex issue and requires further exploration in future research.
