Book Description
Introduction: Initial complexity (Discrepancy Index), treatment time, and treatment outcome (Objective Grading System) were compared for the four examination types of the 2007 and 2008 American Board of Orthodontics (ABO) clinical examination: Initial Certification, Final Recertification, Option 1, and Option II examinations. Methods: Retrospective study using clinical examination data for 1122 ABO clinical exam cases in which the candidate received a passing score were compared. Results: No significant findings were discovered between the four examination types for overall OGS or DI:OGS correlation. However, significant differences were found between the four examination types for overall DI, DI components (overbite, anterior, open bit, occlusion, other), OGS components (buccolingual inclination, overjet, occlusal contacts, occlusal relationship), and treatment time. Conclusions: Compared to private practitioners, cases treated by orthodontic residents had more ideal OGS scores for buccolingual inclination and less ideal OGS scores for overjet, occlusal contacts, and occlusal relationships. Treatment times vary significantly between the four examination types, with resident treatment the shortest and Option II treatment the longest. Prospective examinations (ICE and Option II) differ significantly from Retrospective examinations (Option I (First Recertification).

Book Description
The American Board of Orthodontics (ABO) has made an attempt to improve our profession and attempted to quantify the proper arrangement of teeth after they have received orthodontic treatment. They developed a Model Grading System in order for orthodontists to assess the adequacy and quality of their orthodontic treatment more objectively1. This system was developed in the early 90's and has been used since then. It relies on eight criteria to determine the adequacy of the treatment result. They are: alignment, marginal ridges, buccolingual inclination, occlusal relationships, occlusal contacts, overjet, interproximal contacts, and root angulation. Each one of these criterion is essential to proper orthodontic treatment. This study was an attempt to quantify the relationship of the ABO's Model Grading System to an overall excellent orthodontic result. It also attempted to address the areas that are of concern to orthodontists post-treatment.^Which of the eight criteria are more likely to get worse post-treatment and which will improve. This study was a retrospective study that utilized plaster models from the patient's final records and post-treatment records that were previously taken and recorded. Thirty cases were selected based on completeness of records treated by a single orthodontist (R.G. "Wick" Alexander, D.D.S., MSD). Each of the thirty cases was assigned a number 1-30 to identify them. The inclusion criterion for the study was that both arches were treated orthodontically. The exclusion criterion excluded lower incisor extraction cases from the study. An initial Discrepancy Index for each of the selected thirty cases was performed to determine the difficulty of each case. The final models of each case was then graded using the ABO Model Grading Assessment immediately post-treatment (T2) and at post-retention (T3).^Statistical Analysis was performed on the eight Model Grading System criteria including Paired t-tests and Pearson product correlations. It was shown that marginal ridges and occlusal contacts scored less well at T2 partly because of Dr. Alexander's bracket prescription. These criteria showed a highly significant decrease in score between T2 and T3. The average total score showed a highly significant decrease between T2 and T3 partly because of the large decrease in previous two criteria. Further research needs to be done utilizing more cases treated by more than one orthodontist. This will conclusively determine which of the eight criteria get better or worse with time.

Book Description
Invisalign® is a new orthodontic treatment modality of treating malocclusion with an advanced esthetic approach. It provides an esthetic and hygienic alternative for patients who want to undergo orthodontic treatment without affecting their facial appearance. However, few studies have been published to evaluate the effectiveness of this appliance. Purpose of the Study: The purpose of this study is to evaluate the Invisalign treatment outcome of mild to moderate malocclusions by using the Model grading system (MGS) of the American board of orthodontics (ABO). Materials and Methods: A total of 425 Invisalign® cases were identified from an orthodontic private practice in buffalo, New York State. Of 425 cases, 119 met the inclusion criteria of having full permanent dentition with (DI) score between 10 and 20, and treated completely with Invisalign without extraction. From those 119 cases, only 31 cases had a complete set of records before and after treatment. The pre-and post-treatment models were assessed using the ABO Model Grading System (MGS) .Wilcoxon signed rank test was used to compare the pre-and post-treatment MGS scores in all categories. Results: The mean scores of all MGS categories (except occlusal contacts score and occlusal relationship score) were improved after treatment. Significant improvements were found in OGS Score (45.03"7.47 vs. 35.87"9.36, p
