Extractions as a form of interception in the developing dentition: a randomized controlled trial.

OBJECTIVE: To determine if the extractions of lower primary canines are an effective procedure to relieve crowding of the labial segment. STUDY DESIGN: randomized controlled trial. Subject sample: 83 cases were collected in clinics in Italy, Germany and Wales. The groups were followed over a 2-year period. METHODS: Subjects were randomly allocated to a primary canine non-extraction or extraction group. Dental casts of the patients were collected at the start and at the recall period of the trial. The outcome measures recorded were lower incisor crowding, arch length, intermolar width, overbite, overjet, lower clinical crown heights and lower incisor inclinations. STATISTICS: The Mann-Whitney test was used to compare the differences between the extraction and non-extraction groups. RESULTS: In both groups, crowding reduced 1.27 mm in the non-extraction group and 6.03 mm in the extraction group. The difference between the 2 groups was 4.76 mm (P<0.05). The arch perimeter decreased more in the extraction group by 2.73 mm (P<0.05). As the incisor inclination stayed essentially the same, the loss in arch length was attributed to the molars moving forward. The net gain from extracting deciduous canines was 2.03 mm. CONCLUSIONS: There was a reduction in lower incisor crowding as a result of lower primary canine extraction. However, arch perimeter decreased more in the extraction group leaving less space for the eruption of the lower secondary canines.

Interceptive management of eruption disturbances: case report.

The aim of the present report is to describe a case of a patient with eruption disturbances of an ankylosed lower primary second molar, delayed development of a maxillary permanent canine associated with an odontoma and a class III dental malocclusion. In such a case the objectives of treatment are: to prevent impaction of the lower second premolar and tipping of the lower first molar; to establish correct anterior overbite and overjet and to control the development of the permanent upper canine.

A modified double pedicle graft technique and other mucogingival interceptive surgeries for the management of impacted teeth: a case series.

Maxillary canine is one of the most common teeth that are impacted. This accounts for 1-2% of all patients who attend orthodontic treatment. The key to achieve maximal eruption of these teeth is their surgical exposure and the role of periodontist in such situations is to provide a functional and satisfactory width of attached gingiva on the labial surface. There are different techniques to surgically expose the impacted teeth, namely--gingivectomy technique, apically positioned flap, closed eruption technique, modified apically positioned flap, double pedicle flap and free gingival graft. Selection of the procedure is dependent on the positioning of the tooth in relation to mucogingival junction and attached gingiva. In the present case series we describe three different techniques for uncovering of impacted teeth, which are apically positioned flap, closed eruption technique and a modified double pedicle graft specially planned for the situation. These procedures when selected diligently using sound selection criteria will create adequate width of attached gingiva which minimizes or eliminates the future mucogingival problems.

Maxillary expansion--an interceptive modality in mixed dentition.

Maxillary expansion is a very useful procedure for arch length augmentation, posterior crossbite treatment and removing cross arch interferences. Removable appliances are in the realm of a pedodontist and general dentist. However, one should be aware of the problems arising at an early age of the child, should be able to properly diagnose the condition and if required, a timely referral to a specialist is also expected.

Interceptive orthodontics: the need for early diagnosis and treatment of posterior crossbites.

Crossbites are the result of a malocclusion on the transverse plane of the maxilla and are defined as alterations of the correct alignment of the palatal cusps of the upper molars and premolars with the pits of the lower molars and premolars. Transverse alterations are frequently seen in general dental practices and it is necessary to establish a good differential diagnosis in order to adopt the treatment that will achieve the greatest efficiency and the most stable results possible. Skeletal constriction, dentoalveolar constriction and dental constriction must therefore be differentiated, as each requires different treatment with different orthodontic appliances. This article aims to provide a simple guide to the correct diagnosis of transverse anomalies and to choosing the most suitable orthodontic appliance for each case.

Interceptive correction of anterior crossbite.

The purpose of this paper was to evaluate a passive method to correct anterior crossbite of only one incisor by creating a composite inclined plane. A total of 15 children were selected, aged 6 to 8. The results at the end of one week showed that in all cases the incisor was in normal position.
