This book was released on 2013 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anterior dental crowding is one of the most frequently occurring malocclusions. Both the dental professionals and the general public are critical in evaluating the esthetics of a person by observing the alignment of the anterior teeth. Mandibular anterior dental crowding is one of the most complicated situations bothering both dental professionals and patients even after a period of retention. However, no report documents the perception of the dental professionals and the general public to the lower anterior crowding. The purpose of this present study was to investigate at what level of misalignment of the lower incisors the dental professionals and lay people begin to recognize dental crowding from the ideal alignment A mandibular occlusal photograph of a finished orthodontic treatment case according to the requirements and standards of the American Board of Orthodontics treated at an orthodontic clinic was used in this study. This photograph was altered intentionally to mimic varying degrees of dental misalignment in the lower anterior teeth by rotation of the individual incisors from 0. 5 mm to 2. 0 mm at 0. 5 mm intervals according to Little's irregularity Index. An Internet web page with a total of 16 dental malalignment photos was used to complete a survey by seven groups of participants. These groups are orthodontists, orthodontic residents, other dental specialists, general dentists, dental students, lay people who have or have had orthodontic treatment and lastly lay people who have never had orthodontic treatment. The participants completed the survey by rating each of the photos with a score from 1 to 5. The data were analyzed by using Univariate Analysis of variance. The findings showed that when rating the lower incisor alignment: 1) the orthodontists were most critical than the other groups followed by orthodontic residents and general dentists groups, 2) orthodontists detected the rotation of the central incisor at 1 mm, however, orthodontic residents, other dental specialists, general dentists and orthodontic patients detected the rotation at 1. 5 mm. 3) the rotation of the lateral incisor was detected by dental professionals at 1mm while patients detected the rotation at 1. 5 mm and the lay people detected the rotation at 2 mm. These results provide orthodontic professionals essential information that may help to determine how much dental crowding the general public is willing to accept without treatment or accept after a limited relapse.

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.

Download or read book Twin Block Functional Therapy written by William Clark and published by JP Medical Ltd. This book was released on 2014-09-30 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twin Block appliances are simple bite blocks that are designed for full-time wear. They achieve rapid functional correction of malocclusion (misalignment of upper and lower teeth) by the transmission of favourable occlusal forces to occlusal inclined planes that cover the posterior teeth. The forces of occlusion are used as the functional mechanism to correct the malocclusion (www.twinblocks.com). Beginning with an introduction to orthodontics and twin blocks, the next chapters describe growth studies and diagnosis and treatment planning. Each of the following sections discusses the use of twin blocks for different types of malocclusion. With a focus on the latest developments in functional therapy, the book offers guidance on diagnosis, treatment planning, case selection, appliance design and clinical management. Written by the internationally recognised Orthodontist William Clark from Fife, UK, who also invented Twin Blocks, this comprehensive guide includes nearly 600 clinical photographs and illustrations. Key points Comprehensive guide to use of Twin Blocks in treatment of malocclusion Focus on latest developments in functional therapy Written by UK-based inventor of Twin Blocks Includes nearly 600 images and illustrations
