Interceptive Correction of Anterior Crossbite Using Short-Span Wire-Fixed Orthodontic Appliance: A Report of Three Cases

Introducing a Removable Orthodontic Appliance and Its Effects on Dental Arch Dimensions

Introduction

Guiding anterior crossbite to a normal position is one of the most important responsibilities of a pediatric dentist or orthodontist to gain both esthetic and function. Crossbite with dental etiology can be treated by a variety of appliances. We describe a removable appliance with a different spring design for proclination of more than one incisor in mixed dentition.

Materials and methods

This study is an observational study that was performed on sixteen children, 7–11 years of age, who needed incisor proclination in more than one tooth. In this study, patients were followed until the end of their orthodontic therapy. The variables evaluated were the maxillary arch length, arch depth, intercanine distance, and intermolar distance in pre- and posttreatment. To assess intra-examiner reliability, 10 plaster models were randomly selected and re-measured.

Results

In all the cases, the newly designed removable appliance was used and in all showed a significant increase in arch length, arch depth, intercanine distance, and intermolar distance. The correction was achieved within 1–9 months depending on the patient's compliance.

Conclusion

There was a significant increase in all aspects of arch length and depth after using this appliance. The procedure is a simple and effective method that is recommended for compliant patients needing proclination of more than one anterior tooth; especially in dental class III, pseudo-class III patients, and the first phase of class II division 2 skeletal treatments.

Simple Orthodontic Correction of Rotated Malpositioned Teeth Using Sectional Wire and 2 × 4 Orthodontic Appliances in Mixed-Dentition: A Report of Two Cases

The correction of rotated malpositioned tooth/teeth into the dental arch alignment in the mixed-dentition is often a challenging task for paediatric dentists. Failure in addressing this issue can bring about detrimental effect to the developing dentition and increases the probability of a complex orthodontic treatment in later years. Factors such as severity of the malpositioned teeth, patient's treatment compliance, limitation in specific functions of the selected appliance, availability of bone and space may dictate the success of the treatment. The combined use of a simple sectional orthodontic wire appliance and a 2 × 4 orthodontic appliance has been shown to produce a positive effect. The appliances resulted in derotation of the rotated malpositioned teeth and bringing them into arch alignment in two cases. This treatment option had eliminated the detrimental effects to the developing dentition and helped patients to enhance their smile and dental aesthetics.

Gingival Recession in a Case of Anterior Crossbite with Angle Class I Relationship

Anterior crossbite is one of the most common orthodontic problems encountered during the dental eruption. Usually, the anomaly becomes evident during mixed dentition, as a result of the disharmony between the dental, skeletal and functional components of the orthognathic system. As complications, the presence of the anterior dental cross bite can lead to the thinning of the vestibular alveolar process of the lower incisors and gingival recession. Periodontal changes could recede spontaneously if orthodontic treatment is applied early, in the presence of good oral hygiene. In this case, gingival recession decreased, but not completely receded after orthodontic treatment, although the patient had a good oral hygiene.
