This book was released on 2015 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this study was to evaluate the maxillary central incisor position changes after orthodontic treatment in Class I, II and III malocclusions. Material and Methods: This retrospective cohort study evaluated nighty non extraction orthodontic Class I, II and III cases which were collected randomly from the Orthodontic clinic at the University of Alabama at Birmingham and the Institutional Review Board of the University of Alabama at Birmingham approved the study. All the chosen cases were treated with fixed appliances and according to the standards of American Board of Orthodontics. All the lateral cephalo-metric radiographs were taken using the Orthopantomograph OP100, Instrumentarium Corp.Imaging Division machine(Finland) and traced digitally using the Dolphin Management and Imaging Software, Version05.05.5070.221436(US &Canada). In order to evaluate the maxillary incisor position changes ,the U1-PP(°), U1-SNo, U1-NAo, U1-NA(mm), U1 perpendicular to FH mm(U1-FH) and U1-Oc° cephalometric measurements were carried out based on the post-treatment lateral cephalometric measurements. In order to determine if there is a statistically significant difference in Maxillary central incisor positions among class I, II and III malocclusions , equivalence tests for post-treatment cephalometric measurements were performed using a range of ± 2 either degrees or millimeters Results: The maxillary incisors position does show a significant difference from the normal value among the Class I, II and III. Class III malocclusion presented a greater proclination of maxillary incisor teeth compared to Class I and Class II malocclusions. Class I has a tendency to be more positive of the normal and Class II to be more negative than the normal. The maxillary incisors changes, seem to not fall within the range of ±2 mm according with the equivalent tests for post-treatment cephalometric measurements compared to the respective normal value. The final position of the maxillary incisors after orthodontic treatment depends mainly on the initial position of these teeth and the discrepancy of jaws. Conclusion: There is a significant difference in the positioning of the maxillary incisors among the class I, II and III malocclusions. The post-treatment measurements such as U1-FHmm, U1-NA mm and U1-SN° and U1-NA° present a significance difference among Class I, II and III malocclusions. In In the class II, the maxillary teeth showed to be more upright than Class I and III malocclusions after orthodontic treatment. The U1-PP° showed no significant difference among the malocclusions. In this study, the U1-PP° was the same for r the Class I and III.

This book was released on 2007 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Introduction: There is little information that details the dental changes that accompany pre-surgical and post-surgical orthodontics during orthognathic surgery treatment. Methods: Thirty-four Class II subjects who underwent surgical- orthodontic treatment with mandibular advancement and rigid fixation were selected and the lateral cephalograms digitized. Mean skeletal and dental values were calculated and plotted for pre-treatment, pre-surgical and final treatment time points. Treatment efficacy as a percentage of an ideal goal achieved also was calculated. Results: All data showed there were significant positive changes in the position of the mandible. The mean changes demonstrated: the upper incisors were over retracted pre-surgically and then returned to normal position post-surgically while the lower incisors were proclined and protruded pre-surgically and remained so at posttreatment. The dynamic changes showed that the incisors were not ideally decompensated in many of the cases. This was further substantiated by the efficacy data. Conclusions: The dynamic changes and efficacy data show that pre-surgical orthodontic treatment often does not fully decompensate the incisors, which then limits the surgical outcome.

Book Synopsis State-of-the-Art Orthodontics E-Book by : Hugo Trevisi
Download or read book State-of-the-Art Orthodontics E-Book written by Hugo Trevisi and published by Elsevier Health Sciences. This book was released on 2011-06-09 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The provision of high-quality treatment with good aesthetic outcomes and shorter treatment times are important goals for all practising orthodontists. To facilitate these objectives, the availability of aesthetic appliances with low friction levels together with the introduction of orthodontic mini-screws have allowed faster and more efficient treatment with reduced side effects. The use of contemporary aesthetic appliances and mini-screws also negates the problems seen regarding patient compliance - which can be particularly problematic with adolescents and adults who are reluctant to use head-gear and traditional intra-oral devices. Authored by experts of international renown, Contemporary Orthodontics: Self-Ligating Appliances, Mini-Screws and Second Molars Extraction addresses these issues and is lavishly illustrated to clearly describe the diagnosis and treatment planning of Class II and III malocclusion and the use of second molar extraction. The book particularly explores the use of the ClarityTM Self-Ligating appliance, a device which contains all of the essential features of SmartClipTM but which - by possessing improved aesthetic properties - also demonstrates greater patient acceptability and hence improvement in compliance. Contemporary Orthodontics: Self-Ligating Appliances, Mini-Screws and Second Molars Extraction is ideal for practicing orthodontists both qualified and in training. - Authored by experts of international renown - Lavish use of colour photography and artwork helps explain new concepts clearly - Demonstrates the effective use of the ClarityTM Self-Ligating appliance, a device which contains all of the essential features of SmartClipTM but which also demonstrates greater patient acceptability and hence improvement in compliance - Explains treatment options that show more predictable outcomes, good performance sliding biomechanics, the application of low force levels and reduced treatment times - Ideal for orthodontists worldwide – whether qualified or in training
Book Synopsis Changes to Incisor Anteroposterior Angulation During Correction of Class II Malocclusion by : Long Dao Tieu
Download or read book Changes to Incisor Anteroposterior Angulation During Correction of Class II Malocclusion written by Long Dao Tieu and published by . This book was released on 2014 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: When camouflaging Class II malocclusions, there are often changes to both the maxillary and mandibular incisor angulations that can lead to artificial elongation and/or foreshortening of the dental image. OIEARR is a common result of orthodontic treatment and given the inherent limitations of 2D radiography, it would be beneficial to better understand how changes of tooth angulation can alter the perceived root lengths. With this knowledge, clinicians may be better equipped at recognizing cases of true root resorption as opposed to cases where the appearance of root resorption on the radiograph is due to an imaging foreshortening. This information can help clinicians identify teeth that need further imaging (periapical) to confirm/assess severity of root resorption and will also allow clinicians to make modifications to their treatment in an attempt to minimize the progression of root resorption. Research Question 1. Critically evaluate incisor OIEARR in patients undergoing non-surgical treatment of Class II Division I malocclusion by systematic review of the published data. a.Current evidence suggests comprehensive orthodontic treatment to correct Class II malocclusion results in increased prevalence of OIEARR, however given the fact that there was no RCT and only limited prospective data included in this SR, the findings should be considered with caution. i.Prevalence ranged between 65.6%-98.1% ii.OIEARR -Per patient -- 65.6%-98.1% iii.OIEARR - Per tooth -- 72.9%-94.2% iv.Majority of teeth experienced mild-moderate resorption with severe resorption being reported to be between 6.25-17.2% v.No Sex difference was reported vi.No evidence that either the Mx CI or LI more susceptible to RR vii.Weak to moderate positive correlation between Tx duration and RR viii.Weak to moderate positive correlation between AP apical displacement and RR 2. What is the prevalence of OIEARR over the course of treatment in a selected sample of patients treated with either the X-bow for Forsus? a.Prevalence per tooth 65.3% b.Prevalence per patient 98.6% 3.What is the severity of OIEARR over the course of treatment in a selected sample of patients treated with either X-bow for Forsus? a.Per tooth -- None (34.7%); Mild (45.2%); Moderate (9.3%); Severe (11%) b.Per patient -- None (1.4%), Mild (32.9%); Moderate (30%); Severe (35.7%) 4.Are the incisor length measurements determined from panoramic radiographs accurate and reliable when maxillary and mandibular incisor angulations are modified in a custom made typodont? a.Under experimental conditions, Md incisors appear to respond as expected when compared to theoretical model (assumption -- teeth within focal trough) i.10 degrees -- 1.4% shorter ii.20 degrees -- 6.3% shorter iii. 30 degrees -- 13.4% shorter iv.40 degrees -- 23.7% shorter v.50 degrees -- 34.6% shorter b.Mx Incisors are more difficult to say. At some angulations yes (80, 90), at others (50,60, 70, 100, 110) the answer isn't clear c.Severe Resorption in clinical study was found in 11% of treated incisors and of the 25 patients with at least one tooth with severe RR, 20 of the cases were found on the Md arch 5. When several cephalometric variables are considered simulataneously over time, does sex and or treatment type affect the final outcome in a selected sample of patients treated with either X-bow or Forsus? a.No evidence of a Sex (p=0.840) difference in the overall pattern of cephalometric variables. b.No Evidence of a treatment type (p=0.395) difference in the overall pattern of cephalometric variables. c.Convincing evidence of a Time (p=0.006) difference in the overall pattern of cephalometric variables. d.Convincing evidence (p=0.019) that over the course of treatment OB was reduced by 1.79mm [1.66,1.92]. e.Convincing evidence (p=0.015) that over the course of treatment Y-Axis increased 1.3° [1.24,1.33]. 6.Additional Findings a.Shorter treatment length (p=0.037) with X-bow (24.18 months) compared to Forsus (30.17 months) b.Both compliance free Class II correction protocols (X-bow and Forsus) for the treatment of mild to moderate class II malocclusion appear to generate similar degrees of lower incisor proclination with similar variability. It appears than that foreshortening of the image on a panoramic radiograph due to proclination of lower incisors accounts for a small part, and the larger reason maybe due to the difficulties of accurately measuring the teeth due to distortion caused by the narrow focal trough size or superimposition.
