Combining traditional techniques to correct anterior open bite and posterior crossbite
American Journal of Orthodontics and Dentofacial Orthopedics, 2013
The treatment of anterior open bite often requires the use of skeletal anchorage to prevent excessive eruption of the posterior teeth and consequent downward rotation of the mandible. However, this procedure might not always be accomplished. This article reports the successful treatment of an anterior open bite and a posterior crossbite in a young boy, combining traditional techniques and involving high-pull maxillary traction to help growth to correct the skeletal Class II malocclusion without skeletal anchorage. The vertical dentoalveolar contribution of maxillary growth was also favorable to close the bite, whereas cross-elastics corrected the axial inclination of the mandibular posterior teeth, eliminating the inverted posterior crossbite. The open bite was completely closed with edgewise appliances, which also achieved normal overjet, intercuspation, and incisor exposure on smiling. Traditional mechanics for the treatment of open bite and crossbite remain a useful alternative when patients do not accept skeletal anchorage.
Early Orthodontic Treatments of Unilateral Posterior Crossbite: A Systematic Review
Journal of Clinical Medicine
We aimed to report an update of the systematic review by Petrén et al. (2003). The objective was to evaluate how orthodontic treatments can affect unilateral posterior crossbite (UPXB) in primary and early mixed dentition. Several databases were consulted, and articles published between January 2002 and March 2020 were selected. This review examines the following studies: randomized clinical trials, prospective and retrospective studies with concurrent untreated or normal control groups, and clinical trials comparing at least two treatment strategies. Among the 1581 articles retrieved from the searches, 11 studies were included. Quad-helix (QH) and expansion plate (EP) appliances were compared in three studies. One study compared rapid maxillary expansion (RME) treatment anchored on primary dentition otherwise on permanent molars. One study compared RME and a modified RME with arms extended until deciduous canine and EP. Four studies evaluated the effects of expansion appliances com...
Management of anterior crossbite using various treatment modalities
IP International Journal of Medical Paediatrics and Oncology
Anterior crossbite is the term used to define an occlusal problem involving palatal positioning of the maxillary anterior teeth relative to the mandibular anterior teeth. It has a reported incidence of 4-5% and is usually the result of a palatal malposition of the maxillary incisors resulting from a lingual eruption path. Three male patients reported to the department of pediatric and preventive dentistry, Sri Aurobindo College of Dentistry with the chief finding of anterior cross bite were treated with different fixed and removable treatment modalities. During the early correction of simple and minor malocclusions, which is a part of interceptive orthodontic treatment, the anterior cross-bite is corrected more rapidly & it is achieved by removable appliances or fixed appliances.
Myofunctional Treatment of Anterior Crossbite in a Growing Patient
Case Reports in Dentistry
The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws’ relationship and maximum control of the vertical dimension. After 2 years of follow-up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces. This early treatment of anterior crossbites with EGA may be considered an effective treatment ap...
Effect of Bite Opening on the Correction of Dental Anterior Cross Bite – A Novel Approach
2021
nterior cross bite is a type of malocclusion in which maxillary anterior teeth are placed lingual to the mandibular anterior teeth.1,2 It can be a major esthetic and functional concern for the parents of a growing child. Crossbite can involve a single tooth or multiple teeth.3 Its prevalence is reported to be between 1.6 and 7.9%.1,4 In some studies its prevalence in children is reported to be as high as 27%.3,5 Anterior crossbite may be dental, skeletal or functional in origin.2 In dental crossbite, only tipping /lingual inclination of maxillary incisors are present with no dental compensation and basal bone abnormality.6 It is usually present in early mixed dentition phase. On the other hand, skeletal type of anterior crossbite is either because of an excessive mandibular growth or a deficient maxilla. Functional crossbite, which is also called pseudo-class III malocclusion, is because of the forward posture of mandible from its centric position.7 It might be present because of oc...

Anterior crossbite is defined as a malocclusion characterized by the anterior maxillary teeth lingual position compared to mandibular anterior teeth. Anterior crossbite cases should be treated by emergency intervention in the early period to prevent problems such as abnormal enamel abrasion, periodontal pathologies, temporomandibular joint disorders, mobility, and fractures in teeth that may be caused by an anterior crossbite. In this case report, the treatment of 2 cases with anterior dental crossbite observed during the early mixed dentition period performed with different methods by considering their cooperation, personal characteristics, wishes, and needs is presented.
Management of Anterior Crossbite in Mixed Dentition Using Lower Inclined Bite Plane: A Case Report
IOSR Journals , 2019
Anterior crossbite is a malocclusion involving palatal positioning of the maxillary anterior teeth in relation to the mandibular anterior teeth. Children with untreated anterior crossbite could develop complications such as gingiva recession, TMJ dysfunction and worsening of mandibular displacement. There are different treatment modalities for correction of anterior crossbite in children. The decision on which approach to be used depends on the aetiology of the crossbite, treatment objectives and behaviour of the child. This paper presents a case of a 6-year old child with anterior crossbite involving multiple teeth. A fixed lower inclined bite plane (Catlan's appliance) was used to correct the crossbite. Positive bite was successfully achieved in a short period of time without unwanted effects.
Anterior crossbite malocclusion
Brazilian Journal of Oral Sciences, 2019
Aim: To evaluate the prevalence of anterior crossbite and to verify the effectiveness of the orthodontic appliance Inclined Plane in the correction of this malocclusion. Methods: The clinical examination was performed 702 children in the deciduous or mixed dentition of 7 schools and in those found the anterior crossbite was performed treatment with fixed Inclined Plane. Results: The prevalence of the anterior crossbite was 2.14%, characterizing 15 of the 702 children evaluated, of which 60% were female and 40% male, all of which were dental crossbites. Only 12 accepted the treatment with an average duration of 4.4 weeks. Conclusion: The prevalence of anterior crossbite was 2.14%. The inclined plane proved to be a viable and effective therapy in the correction of anterior crossbite. It is one of the options of the orthodontic treatment in patients in the deciduous or mixed dentition, propitiating greater possibility of dentoskeletal development, since the malocclusion is corrected.

Corticotomy assisted treatment of anterior open bite in an adult patient
Journal of Indian Orthodontic Society, 2016
This case report discusses orthodontic treatment combined with the corticotomy technique to accelerate tooth movement and shorten the treatment time in a 34-year-old female patient with an anterior open bite and flared and spaced upper and lower incisors. Fixed orthodontic appliances (MBT 0.018″ edgewise brackets) were bonded, and 4 months later, buccal and lingual corticotomy with alveolar augmentation procedure in the maxillary arch from canine to canine was performed. Orthodontic therapy proceeded with frequent activation of the appliances to retract the incisors every 2 weeks. The total treatment time was 10 months with an active period of 4 months and no adverse effects were observed at the end of active treatment. The addition of the decortication procedure to the conventional orthodontic therapy decreased the duration of treatment significantly. Successful closure of the anterior open bite with adequate overbite and interdigitation of the teeth was achieved.
