Miniscrew mechanics for molar distalization and incisor intrusion in a patient with a Class II brachyfacial pattern and gummy smile

2020

A gummy smile is one of the most problematic characteristics in patients with a Class II Division 2 malocclusion, and the correction of vertical position and incisor torque is often challenging for the orthodontist. This case report describes the orthodontic treatment of a 31-year-old woman, assisted by miniscrew mechanics for maxillary arch distalization and correction of a gummy smile with a brachyfacial pattern. Two different mechanics were used. Miniscrews were placed in both maxillary tuberosities, and the maxillary arch was successfully distalized, correcting the Class II relationship. Interradicular miniscrews were placed for maxillary and mandibular incisor intrusion to correct the …

Maximum occlusal bite force in pre-school children with different occlusal patterns

2018

Background This study was carried out to record maximum occlusal bite force (MOBF) in pre-school children with different occlusal patterns. Material and Methods A randomly selected sample of 1085 kindergarten children in primary dentition stage were selected. The age of subjects ranged between 3-6 years (averaged 4.90 ± 0.86 years). The subjects were divided into 3 groups according to molar relationship; flush terminal (n=335; 165 males and 170 females), distal step (n=450; 200 males and 250 females), mesial step (n=300; 150 males and 150 females) molar relationship. Clinical examination involved the record of molar relationship, overjet, overbite and the presence of wearing facets. Occlusa…

Dentoskeletal effects of class II malocclusion treatment with the modified Twin Block appliance

2019

Background The purpose of this study was to prospectively assess the dentoskeletal effect of a modified Twin Block appliance for treatment of class II malocclusions. Material and Methods Lateral cephalograms of 25 Class II malocclusion patients were compared to evaluate skeletal, dentoalveolar and soft tissue changes pre- and post-treatment with a modified Twin Block appliance. A total of 33 angular and linear variables were used for analysis. The differences were calculated at the start and end of treatment. The paired T test was performed to compare the cephalometric measurements before and after treatment. Results Compared the pre- and post- treatment measurements, there was a significan…

Influencia de la práctica instrumental en el sistema orofacial

2014

Introducción. El aparato estomatognático es muy importante para los instrumentistas de viento ya que les permite la ejecución musical. Por lo tanto, les debería preocupar su estado en cuanto a función y salud. Se ha observado que una maloclusión puede afectar a la correcta posición del instrumento en la boca, al igual que tocar instrumentos de viento podría influir en el esqueleto dentofacial. Sin embargo la exacta relación entre ellos no se conoce en profundidad. Es a esta relación a lo que pretendemos aportar con este trabajo. Objetivos. El propósito general es valorar los cambios y patologías orofaciales asociadas, con relación de causa-efecto, a la práctica con instrumentos musicales de…

Does breastfeeding have a long-term positive effect on dental occlusion?

2019

Background Breastfeeding produces beneficial effects on a baby's early growth and development, and general well-being. Some studies have associated breastfeeding with better occlusal development. The aim of this study was to assess the long-term effect of breastfeeding on occlusal development in children. Material and methods A retrospective cohort study was conducted to evaluate the occlusions of 320 children belonging to the Spanish INMA Project cohort, monitored from gestation onwards. The association between the duration of breastfeeding and different occlusal traits in mixed dentition (overjet, overbite, openbite, midline displacement, incisor crowding, incisor spacing, diastema, maxim…

Evaluation of the orthodontic treatment need in a paediatric sample from Southern Italy and its importance among paediatricians for improving oral he…

2017

Background Data from epidemiological studies investigating the prevalence and severity of malocclusions in children are of great relevance to public health programs aimed at orthodontic prevention. Previous epidemiological studies focused mainly on the adolescence age group and reported a prevalence of malocclusion with a high variability, going from 32% to 93%. Aim of our study was to assess the need for orthodontic treatment in a paediatric sample from Southern Italy in order to improve awareness among paediatricians about oral health preventive strategies in pediatric dentistry. Material and methods The study used the IOTN-DHC index to evaluate the need for orthodontic treatment for seve…
