ABSTRACT Objective:  To follow a group of children from primary to early permanent dentition and determine the prevalence, self-correction, and new development of malocclusions; the need for orthodontic treatment; and the possible influences of habits, breathing disturbances, and allergies. Materials and Methods:  Two hundred and seventy-seven children were followed at 3, 7, and 11.5 years of age. Malocclusions and orthodontic treatment need were determined by clinical examinations. Data on sucking habits, breathing disturbances, allergies, dental trauma, and orthodontic treatments were collected from a questionnaire and dental records. Results:  Malocclusions were found in 71% of participants at 3 years of age, 56% at 7 years of age, and 71% at 11.5 years of age. Self-correction was noted for anterior open bite, sagittal malocclusions, and posterior crossbite, while deep bite developed. A high number of contact point displacements and spacings contributed to the prevalence of malocclusion rate of 71% at 11.5 years. Severe or extreme orthodontic treatment need was apparent in 22%. Habits, allergies, or breathing disturbances found at 3 years of age had no associations with malocclusions at 11.5 years of age. Conclusions:  This sample revealed a significant percentage of malocclusions and orthodontic treatment need. A substantial number of self-corrections and establishment of new malocclusions occurred during the transition from primary to early permanent dentition.

The aim of this study was to analyze the prevalence and to georeference the malocclusion traits in adolescents in the city of Curitiba, Paraná, Brazil. Data from a previous cross-sectional study with 538 adolescents aged 10 to 14 years were used. In addition, the following variables were used: gender, Health District (HD) of residence, and presence and malocclusion traits. Fisher’s Exact Test, georeferencing, and kernel mapping were used for data evaluation. Malocclusion was observed in 52.4% of individuals, and the most prevalent occlusal trait was deep bite (22.7%), followed by excessive overjet (19.9%), anterior crowding (8.0%), posterior crossbite (6.5%), anterior open bite (4.8%), and anterior crossbite (1.7%). Malocclusion was not associated with gender (p = 0.389) or HD (p = 0.079). However, when stratified by gender, the deep bite prevailed among male. The highest malocclusion trait’s prevalence was observed in the HDs of Cajuru, Pinheirinho, Boa Vista, and Cidade Industrial de Curitiba. Despite the absence of significant differences in relation to gender and HD, the prevalence of malocclusion traits in the sample studied was high, especially for deep bite. Additionally, georeferencing proved to be useful for identifying the distribution of malocclusion in Curitiba.

Adequate planning and early treatment of Angle Class II malocclusion with maxillary atresia and anterior open bite provides harmonization of maxillomandibular bone bases in the three planes of space. Orthodontic aligners have emerged as an alternative treatment having the following advantages: being more aesthetic and more comfortable for the patient, less treatment time when they are correctly indicated, less chairside time, less complications, possibility of remote monitoring, easier feeding, and dental hygiene. On the other hand, they offer difficulties to treat adults with severe skeletal Class II malocclusions, posterior crossbite and anterior open bite. Therefore, the objective of this clinical case report is to early correct skeletal Class II malocclusion with maxillary atresia through the use of mechanical orthopedics and devices that help eliminate habits and close the anterior open bite, and later the use of orthodontic aligners to finish the treatment. It was concluded that the early interceptive treatment of malocclusion was efficient to harmonize the bone bases in the anteroposterior, vertical, and transversal directions, changing this malocclusion from high to low complexity and, consequently, highly predictable and with an excellent prognosis for treatment with orthodontic aligners. The treatment with ClearCorrect aligners corrected the occlusion in a shorter period of time when compared to corrective orthodontics and with a high predictability in relation to the virtual setup.

Abstract Objective: Considering that the available studies on prevalence of malocclusions are local or national-based, this study aimed to pool data to determine the distribution of malocclusion traits worldwide in mixed and permanent dentitions. Methods: An electronic search was conducted using PubMed, Embase and Google Scholar search engines, to retrieve data on malocclusion prevalence for both mixed and permanent dentitions, up to December 2016. Results: Out of 2,977 retrieved studies, 53 were included. In permanent dentition, the global distributions of Class I, Class II, and Class III malocclusion were 74.7% [31 - 97%], 19.56% [2 - 63%] and 5.93% [1 - 20%], respectively. In mixed dentition, the distributions of these malocclusions were 73% [40 - 96%], 23% [2 - 58%] and 4% [0.7 - 13%]. Regarding vertical malocclusions, the observed deep overbite and open bite were 21.98% and 4.93%, respectively. Posterior crossbite affected 9.39% of the sample. Africans showed the highest prevalence of Class I and open bite in permanent dentition (89% and 8%, respectively), and in mixed dentition (93% and 10%, respectively), while Caucasians showed the highest prevalence of Class II in permanent dentition (23%) and mixed dentition (26%). Class III malocclusion in mixed dentition was highly prevalent among Mongoloids. Conclusion: Worldwide, in mixed and permanent dentitions, Angle Class I malocclusion is more prevalent than Class II, specifically among Africans; the least prevalent was Class III, although higher among Mongoloids in mixed dentition. In vertical dimension, open bite was highest among Mongoloids in mixed dentition. Posterior crossbite was more prevalent in permanent dentition in Europe.

This epidemiological survey was conducted on 2,016 children from 8 private and 12 public preschools at the city of Bauru, São Paulo, Brazil. The sample was composed of 1,032 males and 984 females in the primary dentition stage, aged 3 to 6 years. Normal occlusion was observed in 26.74% of the sample; thus, 73.26% of children presented some type of malocclusion. Among the malocclusions, the following transverse problems were diagnosed: unilateral posterior crossbite (11.65%), anterior open bite associated with posterior crossbite (6.99%), bilateral posterior crossbite (1.19%), unilateral posterior crossbite associate with anterior crossbite (0.79%) and full crossbite (0.19%) totalizing 20.81% of the transverse problems. Mandibular functional deviation was observed in 91.91% of children with unilateral posterior crossbite, characterizing the functional unilateral posterior crossbite. The results demonstrated that the prevalence of posterior crossbite was compatible with previous data in the literature, with predominance of functional unilateral posterior crossbite.

Purpose: To evaluate the prevalence of malocclusions in preschool children in the city of Campina Grande, PB, Brazil, and verify the existence of associations between malocclusions and deleterious oral habits, gender and age. Methods: 342 children (3-5-year-old; 196 boys and 146 girls) with complete primary dentition and no previous orthodontic treatment were randomly selected from children regularly attending municipal day care centers. The occurrence of the following malocclusions was evaluated: accentuated overjet and overbite, anterior open bite and posterior crossbite. A calibrated experienced examiner (Kappa = 0.86) performed all clinical examinations under natural lightening after drying the teeth and soft tissue with gauze. Yates' chi-square and Fisher's exact tests verified the association between the variables and odds ratio. Significance level was set at 5%. Results: Malocclusions and deleterious oral habits were observed in 74% and 73.4% of the children, respectively. The prevalence of malocclusion was 68.9% in boys and 80.9% in girls. Accentuated overjet (45%) and anterior open bite (42.4%) were the most prevalent malocclusions. There was statistically significant difference (P = .008) between genders. However, no statistically significant differences (P = .47) were found among the age groups. Accentuated overjet, anterior open bite and posterior crossbite showed a positive association with the presence of deleterious oral habits. Conclusions: The high prevalence of malocclusions and deleterious oral habits observed in this pediatric population is supportive to the fact that oral health professionals that treat patients in these age groups should be aware of the importance of an early and accurate diagnosis in order to avoid the aggravation of occlusal alterations in the future.

Abstract BackgroundAppropriate operations in severe anterior open bite (AOB) cases are extremely complicated to perform because of the multiple surgical procedures involved, difficulty of predicting posttreatment aesthetics and high relapse rate.Case reportWe herein report a 16-year-old girl with skeletal Class II, severe AOB malocclusion and crowding with short roots and aesthetic and functional problems. Four-piece segmental LeFort I osteotomy combined with a posterior horseshoe-like osteotomy was performed for maxillary intrusion, and sagittal split ramus osteotomy (SSRO) and genioplasty were performed for mandibular advancement. The malocclusion and skeletal deformity were significantly improved by the surgical orthodontic treatment. Functional and aesthetic occlusion with an improved facial profile was established, and no further root shortening was observed. Acceptable occlusion and dentition were maintained after a two-year retention period.ConclusionThis strategy of surgical orthodontic treatment with a complicated operative procedure might be effective for managing severe AOB malocclusion.
