Treatment of Class II malocclusions with removable appliances. Part 4. Class II division 2 treatment.

Severe Class II division 2 is a difficult malocclusion to treat properly, especially when lower incisors contact palatal mucosa. Only fixed appliance therapy can achieve worthwhile and lasting improvement of the incisor relationship in this situation. In less severe cases, it may be possible to achieve limited objectives using removable appliances. When planning treatment, extraction of mandibular premolars should be avoided if at all possible.

Dental anomalies in fucosidosis.

Dental anomalies have not previously been recorded in patients with fucosidosis. A new case of this rare disorder is reported, in which a number of variations in both number and morphology of the primary and secondary dentition occur.

Orthodontic clinical screening in under a minute.

A brief clinical orthodontic examination is described as a method of screening young people in practices, community clinics or at school inspections for malocclusions requiring a more comprehensive assessment.

A nasal foreign body detected on routine orthodontic radiographs.

Films used in orthodontics such as lateral cephalograms and orthopantomograms provide excellent visualisation of the maxillary sinuses and the nose, and therefore should be routinely examined for pathology and foreign bodies. We report a case of a long-standing asymptomatic nasal foreign body detected on routine orthodontic films.

A study of the incidence of overeruption and occlusal interferences in unopposed posterior teeth.

OBJECTIVES: To determine the incidence and extent of overeruption in unopposed posterior teeth; to determine the incidence of occlusal interferences associated with unopposed posterior teeth; and to detect an association between the extent of overeruption and the presence of occlusal interference. DESIGN: The study was a single centre clinical retrospective analysis. Setting The setting was in the Combined Care Clinic of Leeds Dental Institute. The patients were undergoing routine restorative care by final year undergraduate dental students during 2000. SUBJECTS AND METHODS: All patients over18 years of age with one or more unopposed posterior tooth, were invited to participate. A sample group of 120 subjects were recruited. A clinical occlusal examination was carried out and the presence of initial retruded contact position (RCP) contacts and excursive interferences were recorded. Study models were made and digitally scanned. OUTCOME MEASURES: Measurements of overeruption from the curve of Spee were made from the images obtained, by a single observer. Reliability of the measurements was assessed by means of a Bland Altman Plot. The presence and site of RCP contacts and excursive interferences were recorded by a single observer. Reliability of the measurements was assessed by means of Kappa scores. The association between overeruption and the presence of occlusal interference was examined using Spearmans Correlation Coefficient. RESULTS: A total of 120 subjects were recruited, with a total of 155 unopposed sites. Eighty-one of the sites belonged to male subjects, 74 to female subjects. The mean age of the group was 50.9 years, Standard deviation 13.9 Eighty-three per cent of sites displayed overeruption (95% CI 78-90), ranging from under 0.5 mm to 5.4 mm. The reliability of the observations was found to be good. A total of 51.6% (95% CI 44-60) of unopposed teeth were involved in RCP contacts or excursive interferences. Thirty-two sites were involved in more than one contact or interference. The intra-examiner agreement was found to be good, using Kappa. The findings of the Spearman's correlation, show that if an association exists between overeruption and occlusal interference, it is weak, and of no statistical significance. CONCLUSIONS: Eighty-three per cent of unopposed teeth are likely to overerupt, and the extent of the overeruption may be marked. The incidence and extent of overeruption is of clinical significance, not only in terms of treatment planning to prevent undesirable vertical movement, but also in the restoration of the edentulous space. The reliability of observations made in the study was found to be good, justifying the methodology. Fifty-one point six per cent of unopposed teeth are likely to be involved in RCP contacts or excursive interferences. The incidence is of clinical significance when planning the restoration of unopposed teeth, or the associated edentulous space. Only a weak statistical association was demonstrated between the degree of overeruption and the presence of occlusal interferences.
