Book Description
A major challenge in orthodontics is to provide a treatment result that remains stable after appliances are removed. Orthodontic treatment can move teeth from their neutral positions, which increases potential for future relapse. The literature from the University of Washington, Seattle, shows that relapse is pervasive and of considerable magnitude (Little RM. Stability and relapse of mandibular anterior alignment: University of Washington studies. Semin Orthod 1999;5:191-204). The intent of this study was to quantify the posttreatment dental changes that occurred over approximately a quarter century in a cohort of women who had received comprehensive orthodontic treatment as teenagers.

Book Description
This is a research-based book on the clinical use of the Herbst appliance in the management of Class 2 malocclusions. Different clinical problems and questions are addressed in the light of the corresponding research existing. Thus, in contrast to other Class 2 alternative treatments, the Herbst appliance approach is based on scientific research.

Book Description
DENTOFACIAL ORTHOPEDICS IN THE GROWING CHILD A clinical guide to understanding why malocclusions occur in children and how to diagnose and correct them early to reestablish normal growth using dentofacial orthopedics Dentofacial Orthopedics in the Growing Child: Understanding Craniofacial Growth and the Management of Malocclusion provides step-by-step guidance on diagnosing and treating malocclusions in young patients. The book addresses both class I, II and III malocclusions, and more complicated cases such as facial asymmetries and temporomandibular problems that develop in the primary dentition. Concise, highly illustrated chapters describe normal and abnormal craniofacial development, and how and why environmental factors can affect the growth pattern. Early diagnosis and treatment planning, long-term case resolution, complementary methods of diagnosis such as occlusion and cephalometric, and more are discussed. Provides clinicians with visual guidance on how to rapidly diagnose malocclusions Contains over 1,300 high-quality images of different Class I, Class II, and Class III malocclusions, including temporomandibular problems, both before and after correction, and long-term follow-ups Helps clinicians correct different malocclusions using the fewest number of appliances and in the least amount of time Includes tables of different cephalometric of before and after corrections for most clinical cases presented in the book Contains a chapter on how to communicate and bond with children as patients to help them understand the importance of wearing their appliances Children are not young adults so diagnostic methods which are regularly used can often misguide the clinician. Dentofacial Orthopedics in the Growing Child is an invaluable reference that guides pediatric dentists, orthodontists, general dentists, and maxillofacial and craniofacial surgeons with treating children.

Book Description
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.
