Dental Arch Relationship

Objective: To compare dental arch relationship and craniofacial morphology of patients with CUCLP in pre-adolescence from five cleft centers including a center using NAM. Design: Retrospective cohort study. Setting: Five cleft centers in North America. Patients: One hundred eighty-two subjects with repaired CUCLP from the five cleft centers participated in the craniofacial form study. One hundred forty-eight subjects from four of the five centers participated in the dental arch relationship study. Methods: Digital dental models were assessed using the GOSLON Yardstick. Eighteen cephalometric measurements were performed. Measurement means, by center, were compared. Analysis of variance and Tukey-Kramer analysis were used to compare GOSLON scores and cephalometric measurements. Results: The center that performed neither PSOT (including NAM) nor primary bone grafting exhibited the most favorable mean GOSLON score. The same center also showed the highest mean SNA, ANB, and ANS-N-Pg angles. However, the mean ANB and ANS-N-Pg angles were not significantly different from those of the center using NAM. No statistically significant differences were seen for mandibular prominence, vertical dimensions, or dental inclinations. The center with NAM also showed a significantly smaller nasoform angle than two of the four other centers. Conclusion: The centers that used NAM and other forms of PSOT did not have better dental arch relationships or craniofacial morphology compared with the centers that performed only primary lip repair. However, this study was not designed to investigate the cause-and-effect relationship between specific outcomes and particular features of those protocols.

Objective: To compare dental arch relationship, craniofacial form, and nasolabial aesthetic outcomes among cleft centers using distinct methods of presurgical infant orthopedics (PSIO). Design: Retrospective cohort study. Setting: Four cleft centers in North America. Patients: One hundred ninety-one children with repaired complete unilateral cleft lip and palate (CUCLP). Main Outcome Measures: Dental arch relationship was assessed using the GOSLON Yardstick. Craniofacial form was assessed by 12 cephalometric measurements. Nasolabial aesthetics were assessed using the Asher-McDade system. Assessments were performed between 6 and 12 years of age. Results: The center that used no PSIO achieved the most favorable dental arch relationship and maxillomandibular relationship, with a median GOSLON score of 2.3 ( P < .01) and an ANB angle of 5.1° ( P < .05). The proportion of children assigned a GOSLON score of 4 or 5, predictive of the need for orthognathic surgery in adolescence, was 16% at the center that used no PSIO and no secondary surgery, compared to 76% at the centers that used the Latham appliance and early secondary lip and nose surgery ( P < .01). The center that used no PSIO and no secondary surgery achieved significantly less favorable nasolabial aesthetic outcomes than the centers using Latham appliance or nasoalveolar molding (NAM) ( P < .01). Conclusions: Effects of active PSIO are multifaceted and intertwined with use of revision surgery. In our study, centers using either the Latham appliance combined with early revision surgery or the NAM appliance without revision surgery achieved better nasolabial aesthetic outcomes but worse maxillary growth, compared to a center using no PSIO and secondary surgery.

ABSTRACT Objectives: To investigate the treatment efficacy and follow-up stability of the asymmetric Forsus appliance by evaluating longitudinal changes in dental arch asymmetry on digital dental models from 21 patients. Materials and Methods: Maxillary and mandibular reference lines were used for measurements of intra-arch asymmetry at pretreatment (T1), posttreatment (T2), and 4.2 years after treatment (T3). Maxillary and mandibular measurements were performed relative to the dental midline and anterior reference line on digital dental models. To determine the amount of asymmetry between the Class I and Class II sides of a given arch, all maxillary and mandibular parameters were measured on each side of the model separately. Repeated-measures analysis of variance/paired sample t-tests were performed to evaluate dental arch asymmetries at the P &lt; .05 level. Results: The alveolar transverse dimensions of the posterior segment of both arches were increased during treatment (P &lt; .05) and remained stable during the retention period. Class II subdivision malocclusion was caused by distal positioning of the mandibular canine, premolars, and first molar on the Class II side (P &lt; .05). Asymmetry was resolved by treatment with asymmetric Forsus appliances. The resolved asymmetry remained stable over the long term. There were no significant differences between T2 and T3 (P &gt; .05). Conclusions: The asymmetric Forsus appliance can be used to treat dental arch asymmetry in patients with Class II subdivision malocclusions.

Background: The aim of the present study was to do an overview of the arch dimension for various populations. Also, to evaluate the various type of measurement methods and sexual disparities. Two reviewers independently performed the selection process and the quality of studies was assessed. Method: Studies published form January 2000 until October 2015 were identified in electronic databases: Pubmed, Scopus, Science direct, Web of Science, Medpilot and Medline using keywords.Criteria used included: observational studies, Arch size measured, Permanent dentition, Arch dimension investigated via plaster and digital dental models, measurement via calipers and computers software’s. Result: The forest plots showed the continuous trend for the greater arch dimension for male in relation to female. The current overview showed the arch dimension and its disparities for various populations. Conclusion: The various methods to assess arch dimension should be carefully considered and well conducted as part of the clinical assessment of orthodontic treatment, since arch dimension could influence the diagnosis and treatment planning of orthodontist.

Introduction: Class II Div 1 is a deviation from normal occlusion and may arise from combination of di" erentcraniofacial components.The objective of this study was to findnd out the different possible dental and skeletalcomponents that lead to Class II Div 1 malocclusion in Nepalese population.Methods: The lateral cephalogramradiographs consisted of 30 males and 30 females between the age group of 18 to 32 years. All the radiographswere traced with hand on acetate paper sheets. All the landmarks were identified, located and marked. Steiner’s analyses and McNamara analysis were done for the cephalometric measurements. The mean valueswere obtained and were compared with the established available values of the Nepalese and Caucasian normsusing independent t-test.Results: Size of the mandible was found to be lesser than the established normalvalues. Prognathic maxilla with retrognathic upper incisors and retrognathic mandible with proclined lowerincisors and was found to be the most common combinations of Class II Div 1 component.Conclusion: Size of the mandible is less than the normal value which is the main cause of the Class II Div 1 pattern in Nepalese population. Medical Journal of Shree Birendra Hospital; July-December 2012/vol.11/Issue2/10-13 DOI: http://dx.doi.org/10.3126/mjsbh.v11i2.7901

Objective To evaluate the effects of active infant orthopedic treatment on dental arch relationships and determine the effect on maxillary growth in children born with unilateral complete cleft lip and palate (UCCLP). Design The GOSLON Yardstick was used to assess dental models taken on patients treated with and without active infant orthopedics. Patients Two groups of nonsyndromic Caucasian children born with UCCLP (total n = 40), all treated by the same surgeon and ranging from 5 to 10 years of age, were evaluated. Interventions One group had a Latham dentomaxillary alignment (DMA) appliance inserted at 5 to 6 weeks of age, after which a lip-nasal adhesion was performed at an average age of 3.5 months. This was followed by more definitive nasolabial repair at the average age of 5.9 months. Those patients treated without preoperative orthopedics underwent a lip-nasal adhesion at average age 1.5 months followed by nasolabial repair at average age 5.1 months. Main Outcome Measures Randomized assessments using the GOSLON Yardstick were done independently at two separate times by three different examiners. Differences in GOSLON scores between the active orthopedic group and nonorthopedic group were evaluated by both categorical and continuous statistical analyses. Results The mean GOSLON score was 3.30 for the orthopedic group and 3.21 for the nonorthopedic group. There was no significant group difference in the modal scores of the two groups. Conclusions This study showed that active infant orthopedics does not affect the dental arch relationships in preadolescent children with repaired UCCLP, compared with a similar group treated without orthopedic intervention at this center.

Objectives: To compare nasal and upper airway dimensions in patients with cleft lip and palate (CLP) who underwent nasoalveolar molding (NAM) with those without NAM during infancy using acoustic pharyngometry and rhinometry. Materials and Methods: Eccovision acoustic pharyngometry and rhinometry (Sleep Group Solutions) was used for assessment of mean area and volume of nasal and upper airway in patients with complete unilateral CLP (age range 16-21 years) treated with NAM (group 1, n = 19) versus without NAM (group 2, n = 22). Results: The mean nasal cross-sectional areas and volume were higher in group 1 compared to group 2 on both cleft ( P value <.001) and noncleft side ( P value >.05). The mean area and volume of upper airway were also significantly higher in group 1 compared to group 2 ( P value <.05). Conclusions: Nasoalveolar molding being one of the first interventions in chronology of treatment of patients with CLP, its long-term outcome on nasal and upper airway patency needs to be ascertained. The results of the present study show that the patients with CLP who have undergone NAM during infancy have better improvement in nasal and upper airway patency compared with those who had not undergone NAM procedure. The basic advantages of being noninvasive, nonionizing and providing dynamic assessment of nasal and upper airway patency make acoustic pharyngometry and rhinometry a diagnostic tool of choice to be used in patients with CLP.
