Dental Arch Form

The aim of an orthodontic treatment is to achieve aesthetic, dental health and the surrounding tissues, occlusal functional relationship, and stability. The success of an orthodontic treatment is influenced by many factors, such as diagnosis and treatment plan. In order to do a diagnosis and a treatment plan, medical record, clinical examination, radiographic examination, extra oral and intra oral photos, as well as study model analysis are needed. The purpose of this study was to evaluate the differences in dental arch form between level four polynomial and pentamorphic arch form and to determine which one is best suitable for normal occlusion sample. This analytic comparative study was conducted at Faculty of Dentistry Universitas Padjadjaran on 13 models by comparing the dental arch form using the level four polynomial method based on mathematical calculations, the pattern of the pentamorphic arch and mandibular normal occlusion as a control. The results obtained were tested using statistical analysis T student test. The results indicate a significant difference both in the form of level four polynomial method and pentamorphic arch form when compared with mandibular normal occlusion dental arch form. Level four polynomial fits better, compare to pentamorphic arch form.

Abstract Objective: To comparatively assess clinical failure rate of brackets cured with two different photopolymerization sources after nine months of orthodontic treatment. Materials and Methods: The sample of this study comprised 30 patients who received comprehensive orthodontic treatment by means of fixed appliances. Using the same adhesive, 600 stainless steel brackets were directly bonded and light cured for 10 seconds with the light-emitting diode (LED) lamp or for 20 seconds with the conventional halogen lamp. A split-mouth design randomly alternated from patient to patient was applied. Failure rates were recorded for nine months and analyzed with Pearson χ2 test, and log-rank test at α = .05 level of significance. Results: The overall failure rate recorded with the halogen unit (3.33%) was not significantly different from the failure rate for the LED lamp (5.00%). Significantly more failures were found in boys compared with girls, in the mandibular dental arch compared with the maxillary arch, and in posterior segments compared with anterior segments. However, no significant difference was found between the right and left segments. Conclusion: Both light-curing units showed sufficiently low bond failure rates. LED curing units are an advantageous alternative to conventional halogen sources in orthodontics because they enable a reduced chair-time bonding procedure without significantly affecting bond failure rate.

Minimum Distortion

It is extremely important to assess variations between the most used radiographs in dental practice, since minimum distortion on obtained images may change diagnosis, treatment plan, and prognosis for the patient. For this, the distance between the enamel-cementum junction and the alveolar bone crest was measured on conventional and digitized periapical, bitewing, and panoramic radiographs and compared among them. From a total of 1484 records, 39 sets of radiographs that fulfilled the inclusion criteria of the study sample were selected. The measurements were grouped according to the intensity of bone loss. Statistically significant difference was found in the averages of the measurements assessed in radiographs with absence of bone loss between conventional panoramic and periapical radiographs, between digitized panoramic and periapical radiographs and between digitized bitewing and panoramic radiographs. By analyzing the results of this work and considering the research protocol used, one can conclude that small losses in height of alveolar bone crest observed in panoramic radiographs should be cautiously evaluated, as they may be overestimated.

ABSTRACT Objectives To compare the cephalometric treatment results of adult deep-bite cases after labial and lingual fixed orthodontic treatment. Materials and Methods A total of 102 patients underwent lingual orthodontic treatment and complete records were evaluated. The following inclusion criteria were used: patients who had Angle Class I or mild Class II malocclusion; comprehensive orthodontic treatment that did not include intrusion mechanics or any extractions; patients with an initial overbite of more than 3.7 mm. Thirteen patients met the inclusion criteria. These cases were matched with the same number of patients according to age with a labial orthodontic treatment group. Pre- and post-treatment cephalometric radiographs were evaluated. Independent t test or Fisher exact tests were performed to assess the differences between the groups. Results Proclination of the upper incisors was higher in the labial group. Incisor mandibular plane angle (IMPA) showed an increase of 1.2° in the lingual group and 9.7° in the labial group. Lower incisor edge was approximately in a stable sagittal position in the lingual group but significant lower incisor proclination was seen in the labial group. The lower incisors were intruded (-1 mm) in the lingual group but lower incisors were minimally extruded (0.3 mm) in the labial group. No significant difference was found in the movements of upper and lower molars for both groups. Conclusions The nature of lower incisor movement involved less protrusion in lingual orthodontics than the labial treatment. Lingual orthodontic treatment is a better option in adult cases where intrusion of lower incisors without labial tipping is desired.

Background: There is great controversy regarding the effect of MBT and Damon bracket systems on dental arch dimensions and incisor position. Objectives: We aimed to study the effects of two different brackets (MBT and Damon) on dental arch dimensions and incisors position after orthodontic treatment. Methods: In this retrospective study, the records of 20 patients who underwent orthodontic treatment with MBT or Damon bracket systems were studied. All patients had class I skeletal and dental malocclusion and were treated without extraction. The patients were treated either with Damon or MBT bracket systems (n = 10). Lateral cephalograms were traced using the Dolphin software to determine the position of incisors. In addition, transverse dimensions of dental arches were measured on occlusal photographs. Fishers’ exact test, independent-test, Man-Whitney, paired t-test, and Wilcoxon were used for statistical analysis. P < 0.05 was set as significant. Results: There was no significant difference between the two groups regarding age, sex, and initial values of the variables studied. U1-Apog (mm), upper inter-canine, lower inter-second premolar distance showed a significant difference before and after treatment in the Damon system. However, no significant difference was observed between initial and post-treatment values in the MBT group. L1-Apog (°), IMPA (°), maxillary inter-first and second premolars, inter-canine, and mandibular inter-canine distance was higher in the Damon system after treatment compared to MBT. Changes of the upper and lower transverse dimensions of the dental arches and the incisor positional did not reveal a notable difference in the Damon and MBT systems (P > 0.05). Conclusions: There was no significant difference regarding changes in dental arches and incisor positions between the Damon and MBT systems.

ABSTRACT Objective:  To examine levels of matrix metalloproteinases (MMPs)-1, -2, -3, -7, -8, -12, and -13 in the gingival crevicular fluid (GCF) of periodontally compromised teeth at different time points during orthodontic movement. Materials and Methods:  Ten controlled periodontitis subjects were submitted to orthodontic treatment. One dental arch was subjected to orthodontic movement, and teeth in the opposite arch were used as controls. GCF samples were collected from the lingual sites of two movement and two control incisors 1 week before orthodontic activation (−7 d), immediately after orthodontic activation, and after 1 hour, 24 hours, and 7, 14, and 21 days. Multiplexed bead immunoassay was used to measure MMPs in GCF. Data were analyzed using Friedman and Wilcoxon statistical tests. Results:  The only significant change found over time was in the levels of MMP-1 in the movement group (P &lt; .05). When the two groups were compared after activation, the only statistically significant difference found was in levels of MMP-12 24 hours after activation (P &lt; .05). Conclusions:  Our findings suggested that the orthodontic movement of periodontally compromised teeth without active pockets did not result in significant changes in the GCF levels of MMPs.

Objective To assess the effect of orthodontic treatment on Goslon Yardstick outcome. Design Retrospective study. Patients A series of 66 consecutive patients born with a complete unilateral left lip and palate. Patients were sorted into a nontreatment group (n = 47) and a treatment group (n = 19). Method Three assessors trained in the use of the Goslon Yardstick ranked the dental arch relationships of study casts taken at 6 and 9 years. Results There was only a fair agreement (κ = .33) between 6- and 9-year Goslon Yardstick scores for the cohort of 66 patients, with a significant (p < .05) difference in the mean score at 6 years (3.17 ± 0.8) and at 9 years (2.88 ± 1.0). Removal of 19 subjects who had orthodontic inventions prior to taking of the 9-year-old study cast improved the agreement to moderate (κ = .52). There was no significant difference (p > .05) in mean scores at 6 and 9 years (3.13 ± 0.9 and 3.17 ± 1.03, respectively). The treatment group exhibited significant differences (p < .001) with mean Goslon Yardstick scores of 3.0 ± 0.9 at 6 and 2.25 ± 0.45 at 9 years. Conclusions The inclusion of patients who had received orthodontic treatment prior to taking of study casts being used for Goslon Yardstick scoring can result in a more favorable outcome. Patients who have received active orthodontic treatment prior to taking of dental casts should be excluded or accounted for in audits to assess primary cleft surgical outcome in patients with a unilateral cleft lip and palate.

Craniofacial Complex

Morphometric data on the structure of the craniofacial complex are reliable and diagnostically significant values that are of applied nature in terms of practical dentistry. Within this study, analysis of conebeam computed tomograms, biometric indicators of plaster models obtained from the jaws of 83 people (aged 21–35) with physiological occlusion and various types of dental, gnathic dental arches, the degree of proportion between the maxillary apical base and the inter-canine distance were identified. Depending on the dental arch type, the patients were divided into three groups. The morphometric study in the CBCT frontal plane was the distance between the canines tearing tubercles and the inter-canine distance in the apical area. The study outcomes revealed discrepancies between the calculated and actual indicators of the apical base width for all types of dental arches in people with physiological occlusion. In case of mesotrusive dental arches (incisional angle — 127–143°), the width of the apical base corresponded to the width of the dental arches between the canines, while the differences in indicators were not statistically significant. In people with retrusive dental arches (incisional angle exceeding 144°), the width of the dental arch was found to be significantly above the width of the apical bases. As far as protrusive dental arches are concerned (incisional angle below 126°), these patients featured predominance of the apical bases width over the inter-canine distance. The obtained data add to that already available in research literature regarding the relationships and dimensional features pertaining to the craniofacial complex structures, as well as have applied value in orthodontic clinical practice

Aim. To improve the graphic method of analysis of the upper dental arch and its segments, to increase the accuracy of upper dental arch abnormalities detection and to minimize orthodontist’s man-hours. Methods. The plaster models of 32 maxillae with dentoalveolar abnormalities were studied before and after treatment. The graphs of individual normal dental arches and its sizes were created by using the geometric and graphic method by Hawley-Herber-Herbst. The regularities were found based on the gained data; graphs of individual normal dental arches (stereotyped patterns) were created using the Adobe Photoshop CS3 software. Dentoalveolar abnormalities were visually examined by directed applying the stereotyped patterns and pictured before and after treatment. 64 models were examined overall. Results. A relation was found: incisors and canines dental crowns half-sum relates to the length and width of Hawley-Herber-Herbst individual normal dental arch graph as 1:2,3:1,3. Considering the relation found, the set of stereotyped patterns was created. The pattern was chosen for the studied model according to the patient incisors and canines dental crowns width. The visual examination allows to recognize and to record (take a picture) teeth malposition, abnormalities of the upper dental arch and its segments in transverse and sagittal planes for correction control. The photos of the models at different stages of orthodontic treatment with stereotyped patterns applied can be added to the patients’ medical chart, indicating the present occlusal rehabilitation success. Conclusion. The offered way of detection of upper dental arch and its segments abnormalities does not require significant time to be performed, is informative and can be implied to clarify the dentoalveolar abnormalities treatment plan.

Background and Aims: One of the main goals of standard orthodontic treatment is having the roots of teeth adjacent to extraction sites parallel to each other. The purpose of this study was to compare standard edgewise and preadjusted straight wire (MBT) methods in achieving this goal.Materials and Methods: For comparing root parallelism, 228 maxillary quadrants and 225 mandibular quadrants of 127 patients in whom 1st premolar had been extracted during orthodontic treatment plan were evaluated. On pre and post-treatment panoramic views long axis of canines and 2nd premolars of each quadrant were traced and the angulations between them were measured to assess root parallelism. For comparing mean value of angulations measured in post-treatmentviews between MBT and SEW method, independent T-test and for comparing root parallelism of canines and 2nd premolars Chi-square test was used.Results: Evaluating root movement and root parallelism of maxillary and mandibular canines and 2nd premolars did not show any statistically significant difference between treatment groups. (P> 0.05)Conclusion: There is no difference between 2 methods of MBT and standard edgewise in achieving favorable root parallelism of teeth adjacent to extraction site. If each of these methods is used properly good root parallelism can be achieved in most of the cases.
