Book Description
Clear aligners are commonly used in orthodontic treatment to correct malocclusions and enhance smile esthetics. There is little quantitative data on how occlusal contacts are altered by clear aligners. This study uses digital intra-oral scans to evaluate how clear aligners affect occlusal contacts and to determine the influence of sex and age on contact changes. Results are compared to contact changes that occur during fixed appliance therapy. Patients included in this study were treated at the University of Washington orthodontic clinic between January 2017-August 2021 and in a local private practice between May 2016-February 2021. Inclusion criteria were a Class I malocclusion treated non-extraction with Invisalign and the presence of digital intra-oral scans obtained before treatment was initiated (T1) and post-treatment following debond (T2). Scans were imported into GOM Inspect Software (GOM Precise Industrial 3D Metrology, Braunschweig, Germany) and occlusal contacts were analyzed. Contacts studied ranged from 0-1.25 mm of space between maxillary and mandibular teeth and were grouped into five categories (tight, near, approximating, open, and no contacts). Analysis was done for the total contact area, anterior area, and posterior areas. The effect of age and sex on contact changes during clear aligner treatment was determined. Changes in occlusal contacts were compared to contact changes that occur during fixed appliance treatment using an existing dataset. A total of 45 patients fit the eligibility criteria for this study. Clear aligners reduced the percentage of tight, near and approximating contacts while the percentage of open and no contacts increased. These changes in occlusal contacts were greater for the older age group studied. Sex influenced occlusal contact changes in the anterior dentition only where the decrease in near contacts and increase in open contacts was greater for males. These results for patients treated with clear aligners were similar to those for patients treated with fixed appliances; both treatment modalities reduce close occlusal contacts at the time active treatment is completed. Clear aligners reduce close contacts and increase open contacts. Overall contact changes during clear aligner treatment are influenced by age, and anterior contact changes are influenced by sex. Clear aligners and fixed appliances result in similar occlusal contact changes.

Book Description
For almost 20 years, clear aligners have seen growing popularity in addressing patients' demands for orthodontic treatment that is also discreet and esthetically inconspicuous. Especially for the adult patient, these almost invisible systems are in considerable demand. Supported by solid clinical evidence, this new work introduces and discusses all the presently available thermoplastically formed products that apply a predetermined strain to the teeth and jaw, with the goal of correcting malpositioned teeth, while also being esthetically acceptable for the patient. Key Features: More than a dozen contributions by top international experts Includes the most recent guidelines on clinical management with aligners Scientific approach presents evidence from material properties research, forces generated with aligners, and treatment outcome assessments Valuable information on changes in oral microbiota, potential side effects, biocompatibility, and more Orthodontic Aligner Treatment will be welcomed by all orthodontic specialists, as well as graduate students, researchers, and clinical faculty in the field.

Book Description
The purpose of this study was to determine differences in occlusal contact area amongst Class I and Class II malocclusions and to determine and compare how orthodontic treatment modifies the occlusal contact areas. The influence of age, gender, initial type of malocclusion, final occlusal classification and type of treatment (extraction vs. non-extraction) was evaluated. This retrospective study included consecutively treated patients from the Graduate Orthodontic Clinic of the University of Washington, who started treatment between January 2017 and June 2019, and were de-bonded by January 29th of 2021. Intraoral scans were obtained pretreatment and immediately after completing orthodontic treatment. A 3D metrology software was used to evaluate occlusal contact areas and interocclusal distances in the 0.25 to -1.25 mm range. Heat maps of the surface area were created, and the areas were recorded for the total surface area of the dental arch as well as for the anterior and posterior segments. The differences in occlusal contacts and interocclusal spaces between the different malocclusion groups, differences due to age, gender, extractions, and time in treatment were analyzed. Occlusal contacts were also compared to initial and final PAR scores. 96 patients were included in this study. Areas of tight, near and approximating contacts reduce significantly due to orthodontic treatment, while areas of open and no contact increase. Age and gender did not have an effect in the overall change of occlusal contacts. There were pretreatment and pre-post treatment differences between subjects with initial Class I and Class II malocclusions. Subjects who received extractions of maxillary premolars have the least amount of posttreatment tight +near+ approximating contacts. After Orthodontic treatment, occlusal contact tends to decrease, several factors influence the amount of contact decrease and the posttreatment amount of occlusal contacts.

Book Description
Introduction: The purpose of the study was to measure the post-treatment changes in the inter-occlusal space one month and three months after comprehensive orthodontic treatment: settling. 3D images acquired during retention were used. The effects of the patients’ demographics and retention protocols on settling were analyzed. Methods: Consecutively finished orthodontic patients were invited to participate in the study. Intraoral scans were obtained at debond, 1-month and 3-months after debond. A 3D Software was used to evaluate the inter-occlusal changes between the upper and lower teeth in a range of distance of -0.6mm to 2mm. A heat map of the surface area was created. Two main categories and six subgroups of height distance were created. The dental arch was also divided into anterior and posterior segments. The changes in the Total Surface Area within Range, area for each category, anterior and posterior portions, the differences between occlusal coverage and no occlusal coverage retainers, age, and gender were compared at all time points. Results: 90 patients were enrolled in the study. The Total Surface Area within Range increased in the first month. The surface area of teeth in the -0.6mm to 0.25mm category stayed constant while the 0.25mm to 2mm range also increased. Similar changes were seen from 1 month to 3 months, but were not statistically significant. The same pattern was observed for the anterior and posterior segments. The increase in occlusal contacts was found in the group of patients wearing retainers without occlusal coverage. In patients wearing retainers with occlusal coverage, the changes were not statistically significant. Gender did not show a correlation with inter-occlusal changes after orthodontic treatment. Adolescents showed a statistically significant increase in Total Surface Area within Range and 0.25mm to 2mm category, while Adults did not. However, there is no statistically significant difference between them. Conclusions: During the first month after the removal of orthodontic appliances, patients show an increase in the total occlusal surface area. This increase is primarily from changes in the inter-occlusal space between teeth that have more than 0.25 mm distance between the upper and lower dentition. The contact surface area of teeth within the -0.6mm to 0.25mm range between the upper and lower teeth remains constant over the three-month period. Anterior and posterior teeth exhibit similar changes throughout the 3-month period. Retainers without occlusal coverage allow changes in the inter-occlusal contacts, while retainers with occlusal coverage do not. A bigger sample size is needed to confirm a relationship with age.
