A biracial sample of two-hundred ninety-six children were assessed for open-mouth posture (OMP) in the natural environment. In addition, rhinometry was performed on 288 of the youngsters. Means were computed for percent OMP and cross-sectional nasal airway. Results indicated that in general these children exhibited relatively high rates of OMP. Boys displayed significantly greater OMP than girls. However, children exhibiting OMP on 80% of the observation intervals had significantly smaller cross-sectional nasal areas than the youngsters who displayed OMP on fewer than 20% of observation intervals. The implications of the findings were discussed.

The focus of this study was an analysis of maxillary arch growth changes prior to the time of cheiloplasty up to 4 years of age. Serial dental casts were obtained and measured in 95 children with cleft lip and palate, or both: 7 unilateral cleft lip and alveolus (CLA), 52 unilateral cleft lip and palate (UCLP), 24 bilateral cleft lip and palate (BCLP), and 12 isolated cleft palate (CP). The children were treated at the Kyushu University Dental Hospital. The results are as follows: (1) Prior to cheiloplasty, the maxillary buccal segments in the subjects with cleft lip and palate showed lateral displacement. The premaxilla in BCLP subjects was protruded. (2) Cheiloplasty influenced maxillary anterior arch width, but not posterior width. The operation caused posterior displacement of the premaxilla in BCLP subjects. (3) Palatoplasty affected the growth of the maxillary arch in the transverse and anteroposterior dimensions. (4) A variety of growth patterns observed in the patients (e.g., increasing or decreasing of the maxillary arch dimensions) suggests that maxillary arch dimensions were affected not only by surgery, but also by other individual factors such as genetic facial pattern and severity of the cleft.

: In prosthodontics, esthetics a combination of the art and science. Patients requiring complete dentures usually expect comfort first, followed by harmonious appearance, and lastly efficiency. Therefore, the correct selection of the artificial teeth is essential for achieving a pleasant esthetic outcome. A number of soft tissue landmarks have been purported as useful for anterior tooth selection; but these are easily affected by several factors such as aging and the weight and build of the person. In the present study hard tissue landmarks like pterygomaxillary notches and maxillary arch width was presented as alternative anatomical landmark for anterior teeth selection. The aim of the study was to evaluate the hamular width and inter maxillary arch width which could be the guide for the selection ofartificial teeth for complete maxillary denture in the North-East Indian population.The study was conducted on 100 dentate individuals from the North Eastern Indian population, between the age group of 18- 30 years. All measurements were done with digital calliper on cast obtained after impression with irreversible hydrocolloid impression material.Pearson correlation analysis showed, statistically significant correlation between maxillary archwidth and central incisor width. The result was significant at p<0.05 but not high enough to be practically used. Correlation between hamular width and central incisor width was found to be insignificant. The value of R was 0.05435. The result was significant at p < 0.05. The maxillary arch width was in direct proportion to the maxillary central incisor width which meant that the increase of maxillary arch width,there was a corresponding increase of maxillary central incisor width. Significant correlation was found between maxillary arch width and central incisor width with p value=0132. The result was significant at p<0.05 but not high enough to be practically used. But In this study statistically insignificant correlation was found between hamular width and central incisor width.

The development of the dental arch is well designed for adaptive and compensatory growth. In this study, the relationship between the sleep position and dental arch development was Investigated. A group of 42 infants with unilateral complete cleft lip and palate with either prone (16) or supine (26) sleep position were seen in the craniofacial center. All infants were less than 1 month of age at the initial visit. Dental impressions of the maxillary arch were taken at the initial visit and just before cheiloplasty. Ten arch dimensions were measured in each dental cast and the longitudinal change in each dimension was compared between the prone sleep group and the supine sleep group. Statistically significant changes were detected in the growth rate of the following dimensions: intercanine width, intertuberosity width, alveolar cleft width, anterior cleft width, and posterior cleft width. This study indicated that sleep position affected maxillary arch development. Infants sleeping in the prone sleep position tended to have narrower arch width and cleft width.

ABSTRACT Objective: To identify differences in occlusal curvatures and maxillary arch dimensions between subjects with signs and symptoms of temporomandibular disorders TMDs and asymptomatic subjects. Materials and Methods: One hundred subjects 78 female and 22 male who consented to participate in this research were examined for signs and symptoms of TMDs according to the guidelines of the Research Diagnostic Criteria for Temporomandibular Disorders RDCTMD. In addition, occlusal measurements were performed for all subjects on plaster models. All statistical analyses were performed with SPSS version 19. Results: Significant associations were revealed between the depth of the curve of Spee COS and temporomandibular joint TMJ sounds. Furthermore, maxillary arch width was negatively correlated to the steepness of the curve of Wilson. No differences were found between subjects with and without a history of orthodontic treatment. Conclusions: Subjects with TMJ sounds tend to have a flatter COS compared to subjects without TMJ sounds.

Summary Objectives To compare posterior crossbite correction frequency and dentoalveolar changes of the expander with differential opening (EDO) and the fan-type expander (FE). Trial design Two-arm parallel randomized controlled trial. Methods Forty-eight patients from 7 to 11 years of age were allocated into two groups. Twenty-four patients were treated with the EDO and 24 patients were treated with the FE. Block randomization was performed. The study was single blind. Digital dental models were acquired before treatment and 6 months after rapid maxillary expansion. The primary outcomes were crossbite correction rate and maxillary arch width changes. Secondary outcomes were interincisal diastema, arch perimeter, length, size and shape, and mandibular dental arch changes. Results The final sample comprised 24 patients (13 female and 11 male; mean initial age of 7.62 years) in the EDO group and 24 patients (14 female and 10 male; mean initial age of 7.83 years) in the FE group. The crossbites were corrected in 100 per cent of subjects from EDO group and in 75 per cent of patients in FE group. EDO showed greater increases in maxillary intermolar region (P < 0.001), while the FE demonstrated greater increases in the intercanine distance (P = 0.008). Increase in mandibular inter-first permanent molar distance was slightly greater in the EDO group (mean difference of 0.8 mm). Changes in arch length and perimeter were similar in both groups. Both expanders changed the maxillary arch shape. The post-treatment arch shape was larger in the anterior region for FE and in the posterior region in the EDO group. Harms Discomfort during activation was reported by 54 per cent of the participants. A temporary change in the nasal bridge was reported by one patient from FE group. Conclusions Maxillary arch width and shape changes were distinct between the EDO and the FE. Greater transversal increases of the anterior and posterior regions were observed for the FE and the EDO, respectively. A slightly greater mandibular spontaneous expansion was observed for the EDO only at the molar region. Trial registration NCT03705871.

Objective: To evaluate the outcome of presurgical nasoalveolar molding (PNAM) therapy in the treatment of patients with nonsyndromic unilateral cleft and palate (UCLP). Design: A prospective study with blinded measurements. Patients: Twelve patients with UCLP treated from 1997 to 2003. Interventions: The starting age for PNAM therapy was 26 days and the average length of the therapy was 110 days. Main Outcome Measures: Measurements of intraoral and extraoral casts were made, and statistical analyses were used to compare the differences between pre- and posttherapy measurements. Results: After PNAM therapy, there was a statistically significant decrease in both intersegment alveolar cleft distance and columellar deviation (p < .05). There was also a statistically significant increase in cleft nostril height, maxillary width, and columellar width (p < .05). Moreover, although there was no statistically significant reduction of the affected nostril width, it demonstrated on average 1.7-mm reduction after PNAM therapy. The length of the time the patient utilized the appliance and postmolding nostril height were found to have a statistically significant positive correlation (p < .05). Conclusions: PNAM therapy decreases intersegment alveolar cleft distance while permitting an increase in posterior maxillary arch width. It also increases nasal symmetry by decreasing columellar deviation, increasing nostril height on the affected side, maintaining bialar width of nose, increasing columellar width, and creating more symmetrical nostril heights and widths. The improvement of the height of the cleft nostril was correlated with the time the appliance was applied.
