Background: A common strategy in the non-extraction treatment of Class II molar relationship is maxillary molar distalization, which could increase lower face height and cause clockwise mandibular rotation. The aim of this retrospective study was to analyse the effects on vertical dentoskeletal dimension of young adults treated with sequential distalization with orthodontic aligners. Methods: Lateral cephalometric radiographs of 10 subjects (8 females 2 males; mean age 22.7 ± 5.3 years) treated with upper molars sequential distalization with orthodontic aligners (Invisalign, Align Technology, San Josè, California, USA) were analyzed. Results: No statistically significant difference was observed for the primary outcome SN-GoGn between T0 and T1 and it was recorded a mean variation of 0.1 ± 2.0 degrees. Statistically significant differences were found in the linear position of the upper molars (6-PP, 7-PP) the molar class relationship parameter (MR) and the upper incisive inclination (1^PP) with at least p < 0.01. Conclusions: Upper molar distalization with orthodontic aligners guarantee an excellent control of the vertical dimension representing an ideal solution for the treatment of hyperdivergent or openbite subjects. It also allows an excellent control of the incisal torque without loss of anchorage during the orthodontic procedure.

Malocclusion and rhinitis in children: an easy-going relationship or a yet to be resolved paradox? A systematic literature revision

et al. 2018

ObjectiveThe relation between nasal flow and malocclusion represents a practical concern to pediatricians, otorhinolaryngologists, orthodontists, allergists and speech therapists. If naso-respiratory function may influence craniofacial growth is still debated. Chronic mouth-breathing is reported to be associated also with a characteristic pattern of dental occlusion. On the other hand, also malocclusion may reduce nasal air flows promoting nasal obstruction. Hereby, the aim of this review was to describe the relationship between rhinitis and malocclusion in children.MethodsAn electronic search was conducted using online database including Pubmed, Web of Science, Google Scholar and Embase. All studies published through to January 30, 2017 investigating the prevalence of malocclusion in children and adolescents (aged 0-20 years) affected by rhinitis and the prevalence of rhinitis in children with malocclusion were included. The protocol was registered at PROSPERO - International prospective register of systematic reviews under CRD42016053619.ResultsTen studies with 2733 patients were included in the analysis. The prevalence of malocclusion in children with rhinitis was specified in four of the studies ranging from as high as 78.2% to as low as 3%. Two out of the studies reported the prevalence of rhinitis in children with malocclusion with a rate ranging from 59.2 to 76.4%.ConclusionThe results of this review underline the importance of the diagnosis and treatment of the nasal obstruction at an early age to prevent an altered facial growth, but the data currently available on this topic do not allow to establish a possible causal relationship between rhinitis and malocclusion.

Cephalometric radiography was innovated by Broadbent and Hofrath in 1931 and thereafter, it has been widely used as a necessary instrument in orthodontic offices for the discussion of malocclusion and vertical skeletal problems, as well as in clinical and research orthodontics by investigators (1,4).

Background: Today, the most commonly used instrument for determining the inferior face height is lateral cephalometry; however, due to the fact that some lateral cephalometric radiographs are given to the patient while taking radiation, and with regard to the overlaps and distortions of structures in this radiograph. Objectives: The purpose of this study was to study the inferior height of the face based on the one-third of the face in photography and then compare its correlation with the results of cephalometry. Methods: This descriptive-analytical study was carried out with photographic and lateral cephalometric radiographs of 75 randomly selected participants (38 women and 37 men) from among patients consulting the orthodontic clinics in Bandar Abbas in 2012 -2013. All participants had all their permanent teeth (without third molar involvement). Patients signed an informed consent form for participation. There was no history of head and face trauma, orthognathic surgery, previous orthodontic treatment, and congenital anomalies. The anterior height of the face was evaluated based on the one-third of the face on photography according to the results of FMA (Frankfort-mandibular plane angle), Sn-GoGN, Bjork, and Jarabak, and the correlations of these values with each other were determined. Data were analyzed by SPSS software using chi-square test, kappa coefficient, and Pearson coefficient. Results: No significant correlation was found between the photographic and cephalometric data of face height (r = -0.03, P > 0.05). There was a significant inverse correlation between the results of FMA and Jarabak index (r = -0.6, P < 0.05). There were significant direct relationships between the results of FMA and those of Bjork (r = 0.8, P < 0.05) and Sn-GoGn (r = 0.7, P < 0.05). There was no statistically significant relationship between the facial form and class I and II skeletal occlusions (P > 0.05). There was no meaningful relationship between the results of FMA angle and facial form in class 1 and 2 occlusion subjects (P > 0.05). However, this association was found stronger in class I than in class II occlusion. Conclusions: There is no meaningful correlation between photographic and cephalometric measurements of facial height, and we always need lateral cephalometrics for the correct orthodontic treatment plan and as a golden standard. Cephalometric variables are correlated with each other for determining the vertical growth pattern, and each can be used for diagnosis alternatively.
