: The Damon passive self-ligating system introduced broad archwires and a passive clip with posterior expansion and with minimal tipping of the teeth. To evaluate and compare the effectiveness of Damon brackets and Damon arch wires in maxillary arch dimensional changes with that of conventional brackets and conventional archwires. A total of 20 patients were selected for the study and randomly divided into 4 Groups with 5 patients in each group. Records (Study models) were taken before starting the treatment (T0) and at the end of leveling and alignment (T1) for all the 20 subjects. Pre-treatment (T0) and at the end of leveling and alignment (T1) study models were assessed for inter canine width, inter first premolar width and inter first molar width. There was statistically significant increase in maxillary arch width in Damon system and conventional bracket with Damon archwires when compared to conventional bracket system and Damon brackets with conventional archwires. The use of conventional or self-ligating brackets does not seem to be an important predictor of change in maxillary arch width in non-extraction patients. The amount of increase in arch width was due to Damon archwires and not because of Damon brackets.

ABSTRACT Objective:  To evaluate the effect of Damon self-ligating and conventional bracket systems on buccal corridor widths and areas. Materials and Methods:  A retrospective sample of consecutively treated patients using either conventional (CG, n  =  45) or Damon self-ligating (SL, n  =  39) brackets was analyzed to determine any differences in buccal corridor widths and areas both within and between groups. Pretreatment and posttreatment frontal photographs were transferred to Photoshop CC, standardized using intercanthal width, and linear and area measurements were performed with tools in Photoshop CC. Ratios were then calculated for statistical analysis. Relationships between arch widths and buccal corridors were also examined. Results:  There were no significant differences in the posttreatment intercanine or intermolar widths either within or between the CG and SL groups. There were no significant differences in any buccal corridor width or area measurement either within or between the CG and SL groups. There were strong correlations with the intercanine width and the corresponding buccal corridor smile width measurements. There was an inverse correlation with the buccal corridor area in relation to the canine and the total smile width. Conclusions:  It is likely that posttreatment increases in arch width can be seen in patients treated with either a conventional bracket system or the Damon system. It is highly unlikely that there is any significant difference in buccal corridor width or area in patients treated with the Damon self-ligating system or a conventional bracket system.

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.

OBJECTIVE: The aim of the present study was to compare dentoalveolar changes in mandibular arch, regarding transversal measures and buccal bone thickness, in patients undergoing the initial phase of orthodontic treatment with self-ligating or conventional bracket systems. METHODS: A sample of 25 patients requiring orthodontic treatment was assessed based on the bracket type. Group 1 comprised 13 patients bonded with 0.022-in self-ligating brackets (SLB). Group 2 included 12 patients bonded with 0.022-in conventional brackets (CLB). Cone-beam computed tomography (CBCT) scans and a 3D program (Dolphin) assessed changes in transversal width of buccal bone (TWBB) and buccal bone thickness (BBT) before (T1) and 7 months after treatment onset (T2). Measurements on dental casts were performed using a digital caliper. Differences between and within groups were analyzed by Student's t-test; Pearson correlation coefficient was also calculated. RESULTS: Significant mandibular expansion was observed for both groups; however, no significant differences were found between groups. There was significant decrease in mandibular buccal bone thickness and transversal width of buccal bone in both groups. There was no significant correlation between buccal bone thickness and dental arch expansion. CONCLUSIONS: There were no significant differences between self-ligating brackets and conventional brackets systems regarding mandibular arch expansion and changes in buccal bone thickness or transversal width of buccal bone.

ABSTRACT Aim The aim of the study is to investigate the galvanic corrosion potential of metal injection molding (MIM) brackets to that of conventional brackets under similar in vitro conditions with nickel-titanium and copper nickel-titanium archwires. Materials and methods Twenty-five maxillary premolar MIM stainless steel brackets and 25 conventional stainless steel brackets and archwires, 0.16 inch, each 10 mm length, 25 nickeltitanium wires, 25 copper nickel-titanium wires were used. They were divided into four groups which had five samples each. Combination of MIM bracket with copper nickel-titanium wire, MIM bracket with nickel-titanium wire and conventional stainless steel brackets with copper nickel-titanium wire and conventional stainless steel brackets with nickel-titanium wires which later were suspended in 350 ml of 1 M lactic acid solution media. Galvanic corrosion potential of four groups were analyzed under similar in vitro conditions. Precorrosion and postcorrosion elemental composition of MIM and conventional stainless steel bracket by scanning electron microscope (SEM) with energy dispersive spectroscope (EDS) was done. Results MIM bracket showed decreased corrosion susceptibility than conventional bracket with copper nickeltitanium wire. Both MIM and conventional bracket showed similar corrosion resistance potential in association with nickel-titanium archwires. It seems that both brackets are more compatible with copper nickel-titanium archwires regarding the decrease in the consequences of galvanic reaction. The EDS analysis showed that the MIM brackets with copper nickel-titanium wires released less metal ions than conventional bracket with copper nickeltitanium wires. Conclusion MIM brackets showed decreased corrosion susceptibility, copper nickel-titanium archwires are compatible with both the brackets than nickel-titanium archwires. Clinical significance Clinically MIM and conventional brackets behaved more or less similarly in terms of corrosion resistance. In order to decrease the corrosion potential of MIM brackets, more precise manufacturing technique should be improved to get a more smoother surface finish.

The aim of this retrospective study was to compare the efficiency of two biologically oriented devices in achieving maxillary expansion: Rapid Palatal Expander (RPE) and Nitanium Palatal Expander-2 (NPE-2). Thirty-six subjects, divided in two equal groups, were included in this study. Maxillary dental arches were scanned using Trios 3 shape®, in order to perform a digital analysis of 3D models. The models were analyzed using Autodesk Fusion 360® and Meshmixer®. All data obtained from analysis of pre-treatment and post-treatment models were processed using Prism® software. The anterior arch width, the posterior arch width, the palate height, and palatal surface were measured to evaluate differences between the devices. A D’Agostino–Pearson normality test was done to check the data. A non-parametric t-test was used to compare the anterior and posterior arch width between the two groups, while a parametric t-test was used to compare the palatal height measurements between the two groups. The p-value was calculated. The limit value fixed was 0.05. Palatal width and surface showed a significant increase in both groups, but no significant changes in palatal height were found. The data processed showed that there were no significant differences between the devices (ΔREP−ΔNPE) in variation of anterior arch width, there were no significant differences in variation of posterior arch width and there were no significant differences in variation of palatal height. The comparison between the two groups showed that both methods were equally effective in correcting transverse defect.

Maxillary Arch

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.
