The case report addresses the challenge of correcting anterior cross bite in mixed dentition period. It emphasizes the complexity of treating skeletal Class III malocclusion, especially in young patients, and highlights the importance of choosing appropriate orthodontic appliances for effective treatment. The subject of the case report is a 9-year-old girl, MK, who presented with a prognathic profile, upper and lower incisor proclination, and bimaxillary protrusion. The treatment plan was multifaceted, incorporating oral prophylaxis, fluoride application, indirect pulp capping, and strategic extractions. Key appliances used were the Quadhelix and Catalans appliances, supplemented by a lower inclined plane, removable Jack Screw appliance with a posterior bite plane, and a Nance Palatal Arch space maintainer. The report meticulously documents the treatment progression with detailed photographs and radiographs, capturing changes at 10 days, 24 days, and 3.5 months intervals. The case report concludes that the use of Quadhelix and Catalans appliances, in conjunction with a comprehensive treatment plan, effectively corrected the anterior crossbite in this patient. The treatment led to significant dental and skeletal improvements, as evidenced by the post-treatment cephalometric analysis. This case underscores the effectiveness of these appliances in pediatric orthodontic cases with similar presentations. Bangladesh Journal of Medical Science Vol.23 (Special Issue) 2024 p.S43-S47

Correction of Anterior Crossbite, Using Removable Appliances in Mixed Dentition: 5-Year Follow-Up

The anterior crossbite (ACB) is a malocclusion where the upper anterior teeth are occluding lingually with respect to the lower anterior teeth. Moyers describes anterior crossbites as dental malocclusions resulting from abnormal axial inclinations of the anterior teeth. This type of malocclusion can be dental, functional or skeletal and can occur in the primary, mixed and second dentition. Diagnosis is made using diagnostic aids. While the treatment was carried out through interceptive orthodontics, with the use of different removable appliances. The objective of the study is to present the diagnosis and treatment for 5 years with the use of removable appliances. The results were favorable, being able to uncross the bite in 4 months, it was maintained throughout the dental replacement. One of the conclusions reached is that the treatment time is slightly longer since the use of preventive and interceptive orthodontics takes more time because these treatments are performed during the growth of the patients.

“Watch them Young – Treat them Grow”: Management of Developing Anterior Cross Bite in Mixed Dentition Period Using Versatile 2x4 Appliance

The primary care of the Paediatric dentist is guidance of the child’s developing dentition, in accordance with the stage of orofacial growth and development . Anterior dental crossbite results from the lingual position of the maxillary anterior teeth in relationship with mandibular anterior teeth. In any type of crossbite correction, the practitioner must be able to delineate whether crossbite is of dental origin or skeletal origin . Dental Crossbite involves the localized tipping of a tooth or teeth, does not involve the basal bone . In case of simple anterior dental crossbite, the patient presents a normal skeletal pattern with abnormalities presenting in the axial inclination of the affected teeth. According to Profitt, first adequate space needs to be opened to bring the displaced tooth or teeth across the occlusion into its proper position for anterior dental crossbite correction. Certain malocclusions should be corrected during the mixed dentition period which aids in the normal growth of jaws and surrounding structures. This article describes successful management of anterior segmental cross bite case treated using 2 x 4 appliance. The 2 x 4 appliance is a partially fixed orthodontic appliance that is used in children in a mixed dentition period to correct simple malocclusions associated with permanent anterior teeth.

A modified Nance appliance for space management and single tooth anterior crossbite correction: Case series

Early loss of deciduous teeth can cause the drifting of teeth reducing the space available for the eruption of permanent successors and thus maintenance of space is critical to prevent malocclusion. At times, multiple decayed teeth can occur simultaneously with a single-tooth anterior crossbite, which is a major functional concern to the dentist and esthetic concern to the parents during the developmental stage of a child. Hence, there is a need for an appliance that can cater to both conditions of space management and anterior crossbite correction concurrently. The following case series focuses on the time taken and the comfort of the patient and for the correction of crossbite using a Modified Nance palatal appliance. All three cases took an average of 1 week for crossbite correction and patients showed superior comfort and compliance.

Nonsurgical Correction of Anterior Crossbite with Extra-Radicular Miniscrews—A Case Report

Protrusion can occur after correction of the anterior crossbite in Class III malocclusions. Four-premolar extractions might be indicated if the patients asked for a profile reduction. Two similar Class III anterior crossbite cases illustrate how the skeletal anchorage can prevent protrusion after anterior crossbite correction and the need for four- premolar extractions, as in the first case. The use of extra-radicular miniscrews at the infrazygomatic crest and buccal shelf are recommended for whole arch distalization of the maxillary and mandibular arches to reduce protrusion after anterior crossbite correction. It is an effective and efficient treatment alternative to extraction therapy for the protrusion after anterior crossbite correction. Long-term follow-up records show encouraging results supporting this paradigm shift in anterior crossbite correction with extra-radicular miniscrews.

Orthodontic treatment protocols in patients with alveolar clefting: a survey of ACPA-approved cleft teams in the United States.

To describe pre- and post-alveolar bone graft (ABG) practice protocols of orthodontists associated with American Cleft Palate-Craniofacial Association-approved cleft and cleft/craniofacial teams. Electronic survey responses from team orthodontists were evaluated regarding pre-ABG orthodontic treatment type(s), timing of post-ABG imaging and post-ABG orthodontic treatment, and craniofacial orthodontic fellowship training status of the team orthodontists. A P value of <.05 was considered significant. Of 31 responding orthodontists, 54.8% had fellowship training and 45.2% did not. Pre-ABG orthodontic preparation ranged from solely maxillary expansion for alveolar segment alignment (35.5%) to a combination of maxillary expansion for both alveolar segment alignment and posterior crossbite correction, anterior tooth alignment, and anterior crossbite correction (19.4%). Most captured post-ABG radiographs prior to orthodontic tooth movement (90.3%). Orthodontists began treatment at least 6 months (35.5%), 2-4 months (32.3%), or 4-6 months (29%) post-ABG. No significant differences were found when comparing fellowship subgroups. In addition, 47.1% of fellowship-trained orthodontists deferred post-ABG orthodontic treatment to at least 6 months post-operatively, vs 21.4% of non-fellowship trained orthodontists (P = .14). A large variation in approaches is evident in pre-ABG orthodontic treatment types and timing of post-ABG treatment. Post-operative imaging is pursued by most orthodontists to assess graft status prior to initiating orthodontic treatment. Additional clinical research is needed to support providers in their decision-making with regard to evidence-based approaches.

COMPARATIVE EVALUATION OF THE EFFECTIVENESS OF FIXED VERSUS REMOVABLE ORTHODONTIC APPLIANCES IN CORRECTING ANTERIOR CROSSBITE IN MIXED DENTITION.

Background: Anterior crossbite is a common malocclusion whose prevalence vary from country to country. It is around 6-8% in India. Aim &amp; Objective: To evaluate the effectiveness of fixed versus removable orthodontic appliances in correction of anterior crossbite in the mixed dentition. Material &amp; Methods: A sample size of 75 subjects were selected on differential selective criteria with history of no previous orthodontic treatment, mixed dentition, anterior crossbite with moderate space discrepancy (&lt; 3mm), non- extraction orthodontic mechanotherapy with ANB &gt; 0°. A written consent was signed. Treatment with two parallel mode was designed, either with a removable appliance with springs or a fixed appliance with orthodontic brackets. To standardize the design for evaluation "Randomized Controlled Trials" (RCTs) were applied and parameters like rate of success, treatment duration, pre &amp; post treatment differences in the overjet, overbite and arch length were accessed. Results: The treatment was successfully completed in all the patients by both the treatment modalities. Method Error Analysis (MEA) &amp; Statistical Package for the Social Sciences (SPSS) were used for statistical analysis. SPSS significantly showed the average treatment time by the fixed appliance was comparatively less (1.4 months, P &lt; 0.05). Increase in arch length and overjet in both treatment modalities were recorded, but it was significantly higher in fixed mechanotherapy (P &lt; 0.05 and P &lt; 0.01). Conclusion: Both, fixed and removal orthodontic appliances can successfully treat anterior crossbite in mixed dentition with short- term orthodontic treatment.

Correction of anterior crossbite with inclined bite plane: a literature review

Anterior crossbite is a condition that occurs due to discrepancy between the maxillary and mandibular anterior teeth in occlusion which the maxillary teeth are more lingual than the mandibular teeth. Anterior crossbite often occurs in children in the mixed dentition phase, so treatment is needed as early as possible to eliminate the causes of malocclusion and the need for more com-plex orthodontic treatment. There are various treatments for anterior crossbite, one of them is the inclined bite plane. This litera-ture review aims to determine the treatment of anterior crossbite with inclined bite plane and the factors that influence the duration of treatment. The method used is to collect literature from search engines such as Pubmed, Scielo, Google Scholar, Science Di-rect, Elsevier, Ajodo.org which discusses the treatment of anterior crossbite with inclined bite plane, then reviewed. From the results of the journal search, 7 literatures relevant to the topic were obtained. From the results of the literature review, it can be concluded that the treatment of anterior crossbite with inclined bite plane is quite effective. The factors that influence the du-ration of treatment are motivation, cooperation, and the type of inclined bite plane that used by the patient.

Anterior crossbite correction in early mixed dentition stage using functional jaw orthopedics principles: a case report with two-years follow-up

A five-year-old and four-month-old male patient presented with Class I malocclusion, anterior crossbite (pseudo-class III) with an overbite, midline deviation to the left (5 mm), left unilateral chewing preference, and incisors in bi-retrusion with diastemas. Initial Bimler cephalometry showed negative anterior face angle (&lt; A), negative bone overjet (A’B’), mesoprosope biotype, negative suborbital facial index, microrhinic dysplasia, and reduced T-TM distance. Pre-treatment gnathostatic models revealed vertical asymmetry and increased left occlusal plane. After the initial assessment, we initiated the treatment with resin-composite planas direct tracks in the deciduous upper molar surface to lift the bite. The patient was oriented to perform right-side mastication movements using hyperboloid exercises. After one month, a new resin-composite lift was carried out in the lower deciduous molar occlusion surface. Planas direct tracks were built directly on the occlusal of the maxillary molars 64 and 65 to start centering the patient’s midline, which was deviated to the left, raising the bite, and increasing the vertical dimension. In the same dental appointment, we completed the right side on the occlusal of the teeth 54 and 55, to adjust the occlusion using 200 microns articulated paper. After a month, the patient returned to the dental office and resins were placed in the occlusal surface of teeth 74, 75, 84, and 85, completing the direct planas tracks and leaving the occlusal plane the most parallel to the Camper’s Plan. Direct planas tracks’ adjustments were made throughout the patient's treatment returns, with 200 microns articulated paper and selective wear. Hyperboloid (silicone-made accessory to stimulate the stomatognathic system) was used to perform chewing exercises on the right side and instructed to be performed before the main meals, for five minutes, encouraging chewing on the right side. The subsequent masticatory evaluation showed protrusive movements. To reduce this movement, planas direct tracks from canine-to-canine were prepared, correcting the anterior bite, and reducing the midline deviation to the left. Posteriorly, functional orthopedic treatment began with the Simões Network 3 (SN3) device, with Bimler’s upper dental arch not touching the incisors and an upper expander. Concomitantly, in the lower dental arch, we initiated the treatment with a Hawley dental appliance against the cervical third of lower incisors and a W-shaped lingual retainer. The SN3 device was built in a laboratory specialized in maxillary functional orthopedics, after molding the patient with alginate and wax bite registration. After 12 months of treatment, the patient presented a centralized midline, had permanent lower incisors, erupting upper central incisors, and adequate bilateral chewing. After 24 months of treatment, the patient presented physiological limits with the contact of the upper central incisors in a determined area with 2 mm overjet, centralized midline, efficient bilateral chewing, and balanced maxillomandibular growth. Post-treatment Bimler cephalometry showed a negative anterior face angle (&lt; A), positive bone overjet (A’B’), mesoprosope biotype, increased T-TM distance. In addition, Planas’ gnathostatic models evidenced a symmetric occlusal plane. In conclusion, functional jaw orthopedics approaches can significantly contribute to the inhibitory and excitatory stimulation of the mandible to the maxilla. Furthermore, functional orthopedics might establish an appropriate development of the stomatognathic system in patients with mixed dentition.

Orthodontic Treatment for a Child with Melanotic Neuroectodermal Tumor during Infancy: A Case Report

Background: Melanotic neuroectodermal tumor of infancy (MNTI) is a very rare tumor, and case reports of orthodontic treatment for patients with MNTI may be previously unreported. This article describes the orthodontic treatment for a 7-year-old girl with MNTI in the mandible. Case: Her chief complaint was anterior crossbite. Although she had an MNTI diagnosis at the age of 8 months, it remained subclinical. Therefore, she has been regularly followed-up by computed tomography (CT) and magnetic resonance (MR) imaging without aggressive treatment. We had worried about the stimulation of MNTI on the mandible by changing her occlusal position with orthodontic treatment. Therefore, we sufficiently explained to her and her family that orthodontic treatment was at risk for worsening MNTI. However, they desired treatment that consisted of maxillary protraction and slow expansion to correct anterior crossbite and encourage the permanent tooth eruption. After 19 months of active orthodontic treatment, the anterior crossbite was improved, and the eruption of permanent teeth made good progress. No evidence of progression and exacerbation of MNTI has been found by both CT and MR imaging. As the observation period is still short, we need a careful and long-term follow-up of her occlusion and MNTI. Furthermore, when we encounter rare cases without previous experience and reports, informed consent was of particular importance.

Reciprocal force generated by two sliding jigs: An alternative mechanic for molar protraction

Objective: When a first molar is lost, orthodontic replacement with second and third molars would be an excellent treatment option. There are some side effects that tend to occur during molar protraction, such as mesial tipping of molar that could increase the time required to correct. These side effects can be avoided by understanding the biomechanical variables affecting molar protraction. The author tries to present the modification of sliding jigs, instead of the power arm function, with additional of lingual force, for molar protraction.Methods: This case report describes the management of a 23-years-old woman who was missing left mandibular first molar, had class III skeletal profile, and anterior crossbite. After anterior crossbite correction, the left mandibular first molar extraction spaces were closed by protraction of the second and third molars. Mesial tipping was detected in the early protraction phase when using conventional method. Consequently, uprighting procedure was done and protraction was continued using reciprocal force generated by two sliding jigs and lingual buttons to achieve bodily movement of tooth.Results: The result was excellent, the space was closed without tipping and rotation.Conclusion: The presented article provides an alternative mechanic for molar protraction using sliding jigs and how it can be designed to achieve predictable result.

Simplified Fixed Technique for Correction of Anterior Crossbite: A Case Series

Anterior crossbites would normally require early intervention, especially when associated with mandibular displacements. The intervention would usually commence in children around the age of eight and nine, where treatment could be a challenge at this age. Therefore, a simple and quick treatment to this malocclusion would be desirable. This case series illustrates two cases of anterior crossbite with a functional shift that were successfully corrected using a simplified fixed technique, which involved a short-span nickel-titanium (Ni-Ti) aligning round archwire, composite resin and glass ionomer cement (GIC).

Upper airway changes in Class III patients using miniscrew-anchored maxillary protraction with hybrid and hyrax expanders: a randomized controlled trial.

The aim of this study was to compare the upper airway space changes after miniscrew-anchored maxillary protraction with hybrid (HH) and conventional hyrax (CH) expanders. The sample comprised Class III malocclusion growing patients that were randomized into two groups of miniscrew-anchored maxillary protraction. The group HH was treated with a hybrid hyrax appliance in the maxilla and two miniscrews distally to the canines in the mandible. Class III elastics were used from the maxillary first molar to the mandibular miniscrews until anterior crossbite correction. The group CH was treated with a similar protocol except for the conventional hyrax expander in the maxilla. Cone-beam computed tomography was obtained before (T1) and after 12 months of therapy (T2). The shape and size of upper airway were assessed. Intergroup comparisons were performed using Mann-Whitney U test (p < 0.05). The group HH was composed of 20 patients (8 female, 12 male) with a mean age of 10.76 years. The group CH was composed of 15 patients (6 female, 9 male) with a mean age of 11.52 years. Anteroposterior and transverse increases of the upper airway were found for both groups. The oropharynx and the most constricted area increased similarly in both groups. No differences in upper airway changes were observed using protraction anchored on hybrid or conventional hyrax expanders. Maxillary protraction anchored on hybrid or conventional hyrax expanders may benefit patients with breathing disorders due to the increase of the upper airway volume and most constricted area. Registration: ClinicalTrials.gov (NCT03712007).

After one week of insertion, majority of the cases 30(60%) still had difficulty in producing the same sounds. While, After one month of insertion, most of the cases 40(80%) had no problem in producing different sounds . Conclusion : The speech performance while using removable anterior expansion screw for was worst immediately after placement of the appliance and 1 week respectively and improved after one month of appliance insertion.

Full mouth rehabilitation in anterior crossbite and posterior bite collapse patient – A case report

Background : Esthetically and functionally successful full mouth rehabilitation requires careful attention and me-ticulous treatment planning. Successful restoration in a patient with anterior crossbite and a partially edentulous situation can be challenging especially when bilateral posterior segment teeth is missing. Combination restora-tion using attachment retained removable partial denture (RPD) and removable partial overdenture (RPO) is such kind of treatment modality in prosthodontics. Purpose : This study was to provide an overview of a case about full mouth rehabilitation in anterior crossbite and posterior bite collapse patient. Case : A 64-year-old female pa-tient came to Prosthodontic Department of RSGMP Universitas Airlangga to have dentures replacing her missing teeth with aesthetic issue on her anterior teeth in order to eat well and be more confident. The patient wants to change her smile into new smile with acceptable aesthetic and function. Management : Diagnostic wax-up was made to capture the right occlusal vertical dimension (OVD) in centric relation (CR) that will be used in the first stage of full mouth rehabilitation, followed by management of the remaining teeth by endodontic and periodontal intervention by crown lengthening. Then, definitive restorations were made by maxillary attachment retained RPD with splint four anterior crowns and mandibular RPO with two single crowns on the lower teeth to correct anterior crossbite and posterior bite collapse. Conclusion : Patient had a satisfactoryly aesthetic and functional results with new occlusion using maxillary attachment retained RPD and mandibular RPO.
