“…There is numerous literature covering case reports on the occurrence of dental anomalies with unerupted permanent incisors, namely hyperdontia, ectopic eruption of permanent canines, odontomas, microdontia, transposition of permanent canines, hypodontia, enamel hypoplasia, predominantly/exclusively hypoplastic forms of amelogenesis imperfecta, molar‐incisor hypomineralization, dentigerous cyst, solitary bone cyst, regional odontodysplasia, talon cusp, horizontally‐impacted mandibular permanent lateral incisor associated with double teeth and involving the mandibular primary lateral incisor and canine, and infraoccluded primary molars . Additionally, research studies have shown the possible association of dental anomalies with the occurrence of various kinds of dental conditions, such as ectopic maxillary canine, malocclusion, non‐syndromic cleft lip with or without cleft palate, Down syndrome, hypodontia, and hyperdontia .…”

Aim:The aim of the present study was to investigate the association between unerupted permanent incisors and dental anomalies among children and adolescents. Methods:The clinical records of patients between January 2005 and December 2014 were retrieved to identify those with unerupted permanent incisors. A retrospective audit on the presence or absence of any dental anomalies was done from all available records of the included patients. Results:A total of 266 patients with 320 unerupted permanent incisors were identified from the 15 987 patients in the study. Among the unerupted permanent incisors, 222 (69.4%) were associated with dental anomalies, which was significantly higher than those showing an absence of dental anomalies (N = 98, 30.6%, P < 0.001). For the unerupted maxillary central incisors, a significantly higher proportion was associated with supernumerary teeth (P < 0.001). For the unerupted maxillary lateral incisors, a significantly higher proportion was associated with the ectopic eruption of permanent canines when compared with other dental anomalies (P < 0.001). The presence of the ectopic eruption of permanent canine, double teeth, and hyperdontia was significantly higher among male patients with unerupted permanent incisors. Conclusions:Unerupted permanent incisors were associated with supernumerary teeth and ectopic eruption of permanent canines. Specifically, a higher proportion of unerupted maxillary central incisors was associated with the presence of supernumerary teeth, whereas a higher percentage of unerupted maxillary lateral incisors was associated with the ectopic eruption of permanent canines.

Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through subjective face analysis and cephalometric data, as well as the occlusion of patients with and without (control) dental anomalies. The relationship between the presence of dental anomalies and malocclusion was analyzed by the Chi-square test with significance level of 5%. Results: 73 children (27.8%) presented dental anomalies, being 49.3% in girls and 50.7% in boys in a total of 88 teeth involved. Anomalies observed in decreasing order were: enamel hypoplasias, eruptive ectopias, agenesis, supernumerary teeth, corono-radicular dilaceration, microdontia, transposition and imperfect amelogenesis. Of these, 22.2% presented associated dental anomalies, whose ectopic eruption with enamel hypoplasia were the most frequently encountered. When comparing the control group with children with dental abnormalities it was observed a significant relationship between the presence of dental anomalies and malocclusion (p<0.05). The most frequent alteration among patients with dental anomalies was deep overbite (24.6%), followed by crowding (23.3%), posterior crossbite (14.2%), anterior open bite (12.9%) and anterior crossbite (0.3%). Conclusion: Dental dysgenesis interferes with the development of occlusion and the resulting occlusal problems are distributed differently, taking into account the skeletal facial pattern in patients with and without dental anomalies.

“…8 Segmented archwire technique with cantilever or loops in rectangular wires is commonly used to achieve these results. 4,[9][10][11][12] Using this technique, the moving and anchor parts are clearly divided, and the force system is well controlled. However, this approach requires precise laboratory work and sometimes creates discomfort for the patient.…”
