- The primary aim of this study was to evaluate our patients' experience of their treatment period with a fixed appliance and their opinions about the results five years after completion of active treatment. A second aim was to assess bonded lingual retainers and their potential side effects. A final aim was to compare the results in a postgraduate clinic (Göteborg) and a specialist clinic (Vänersborg). This study included 170 patients who finished their active treatment in 1997-1998. Eighty-three patients were from Göteborg (postgraduate clinic) and 87 from Vänersborg (specialist clinic). The patients were examined for visible calculus, approximal caries in the anterior regions, gingival recessions and the status of existing retainers in the upper and lower anterior teeth. All patients completed a questionnaire and were interviewed after undergoing a clinical examination. The statistical methods used were descriptive analysis and the chi-square test. The main reason for orthodontic treatment was appearance and most patients (94%) were satisfied with their treatment result. Our results showed a significantly higher frequency of loosened or fractured retainers at the postgraduate clinic compared to the specialist clinic (p < 0.01), which might be explained by operator sensitivity in bonding retainers. There was a tendency for calculus to develop more easily with than without retainers. CONCLUSION: Patient satisfaction of the treatment given at the postgraduate clinic was the same as at the specialist clinic except for more frequent loosening of bonded retainers.

- The objectives of this study were to investigate (1) the results of treatment with functional appliances in mixed dentition run by general practitioners, (2) factors associated with a final treatment result of overjet of > or = 5 mm and (3) the need of additional treatment with fixed appliances. The study was designed as a retrospective, cross sectional survey and conducted in one of the Public Dental Clinics and the Orthodontic Clinic in Lidk?ping, Sweden. 122 patients (aged 7.6 -13.2 years) with an overjet of > or = 7 mm and consecutively collected for treatment with functional appliance therapy. Patient files were analysed with regard to gender, age, initial class II severity, type of functional appliance, co-operation, overall growth, number of missed appointments and treatment time. The treatment results were studied and correlated with the above-mentioned variables. The need for additional treatment with fixed appliances was evaluated. A final overjet of < or = 5 mm was observed in 61.5% of the patients, 48.4% interrupted treatment prematurely and 33.6% received additional treatment with fixed appliances. Good co-operation and extended treatment time was found to be correlated with a final overjet of < or = 5 mm. Other factors not associated with treatment outcome were age, gender, overjet, overbite, molar relation, type of functional appliance, overall growth and number of missed appointments. Activator treatment was successful in reducing overjet to 5 mm or less in almost two thirds of the treated patients. Mainly because of poor functional appliance treatment results or relapse, one third of the patients were retreated with fixed appliance. Since good co-operation is one of the main factors for successful treatment outcome, evaluation of the motivational level of both the parents and the patient before treatment start is crucial.

- The aims of this study were to 1) evaluate the objective success rate of Class II malocclusion treatment with functional appliances five years after completion of treatment and 2) to compare the remaining objective treatment need with an untreated control group. Records of all listed patients between 18-20 years (n=1054) treated in a general practice were reviewed for the purpose of finding treatments with removable functional appliances. Among all subjects (n=61) who previously had been treated, 58 accepted to participate in the study.The test group was matched with an orthodontically untreated group with no history of objective treatment need. Clinical, examination was performed and study casts and photos were taken from both groups. The objective treatment need was evaluated through clinical examination and study cast analysis with weighted Peer Assessment Rating index (wPAR). Twenty patients,.(34.5 %) (mean wPAR 13.8), succeeded with the functional appliance treatment.The wPAR score (mean 15.o) of the entire test group was significantly higher than the one of the control group (mean 7.3).The group that was treated exclusively with functional appliances had a mean wPAR score of 17.4. Eighteen patients (31.0 %) who received retreatment with fixed appliances had a slightly higher mean wPAR (8.6) than the control group. Treatments with functional appliances in a general practice showed a high failure rate and a remaining treatment need. It is the treating dentist's responsibility to motivate the patient to cooperate to the treatment, because as it previously has been shown the treatment with functional appliances is a well-functioning treatment alternative with the cooperation of the patient being sufficient. It is also of importance, already before starting treatment, to estimate the child's cooperation ability and to avoid treatment with removable appliances if the child or parents are reluctant about such a treatment.
