Snoring and Obstructive Sleep Apnea (OSA) are caused by repetitive dynamic closure of the oropharyngeal airway. There exists substantial and growing epidemiologic evidence that OSA is associated with a variety of systemic conditions, including but not limited to, systemic hypertension, stroke, congestive heart failure, increased motor vehicle accidents, impaired quality of living and mortality. There is an equal amount of literature on the use of dental appliances as a treatment modality for OSA. The object of this report is to review the literature in regards to three vital aspects of this disease: a) the etiology and sequela of OSA; b) the dental management of the condition and its mode of action; and lastly, c) the positive and negative outcomes/risks, of dental management.

Obstructive Sleep Apnea Syndrome (OSAS) is a frequently occurring childhood malady, whose is incidence is largely underestimated, that can lead to serious complications. Because of their understanding of the anatomy and physiology of the masticatory apparatus and of the upper airways, orthodontist are in a strategic position to detect in their young patients developing disorders in these regions; accordingly when they suspect the existence of OSAS they should ask systematic and well targeted questions of parents who may not be aware of the relationship between certain symptoms their children display and sleep breathing problems. The goal of this article is to provide practitioners with a better understanding of the symptoms and the physio-pathological mechanics of OSAS so that they can spare their afflicted patients the complications it provokes by seeing that early treatment is undertaken.

Orthodontists, thanks to their keen appreciation of facial morphology and their skills in making functional examinations, are ideally placed to detect breathing problems in their patients that can require an ENT assessment, with special attention paid to the evaluation of sleep patterns. After a site of obstruction, resulting from a soft tissue anomaly and/or a narrowing of the airway passage through bone, has been established, orthodontists may be called upon to undertake corrective treatment sometimes in conjunction with a surgical procedure.

More and more adults are beginning orthodontic treatment because they want to regain the smile they had when they were 20 years-old and to diminish the signs of aging their faces present to degrees that depend upon the severity of their dento-facial deformity. The dental esthetic criteria that are sought after and regained with treatment are, primarily straightening and whitening of teeth, and a smooth appearance of the teeth and their mutual contours, predominantly in the upper incisor area as well as a regular, broad smile line in harmony with the lower lip. In addition to these dental guide lines, additional important consideration should be taken of the relationship of the size and bulk of the teeth with respect to facial type and the absence of any strain in lip posture. Orthodontic treatment, in correcting malocclusions of varying severity, can effectively join with other specialties in creating a younger smile line for patients and eliminating many signs of aging.

The goal of this study was to discern the nature of the transverse changes that a treatment of sequence propulsions with Herbst connecting rods with no expansion component produced. Thirty one patients treated with Herbst connecting arms9,14,15 attached to splints that had no expansion screw were selected. After this propulsion stage, treatment for these patients was continued with appliances that also had no expansion component. On study models, we recorded distances between opposite first molars and measured angular variations of these teeth in the frontal plane. We compared these figures with Moorrees12 tables that furnish natural increase in transverse distance and used the Marshall11 table to give a base measurement of natural angular modifications (“torque”). Our results showed that a sequence of propulsion treatment created enough adaptation of the shape of the upper arch to make the application of expansion mechanics unnecessary.

Apical root resorption is one of the principal undesirable side effects associated with orthodontic treatment. It is provoked by a number of etiological causes, most often mechanical in nature and can be aggravated by biological factors that are not yet clearly understood. The objective of our study was to determine the influence of anomalies in dental organogenesis on the occurrence of root resorption. We analyzed the radiographs of maxillary incisors taken before and after treatment of 85 patients observed by the same practitioner. The results of our study suggest that patients with dental anomalies, anomalies of dental conformation, especially of the type of microdontia/thin root, have an increased risk of suffering from apical root resorption of maxillary central incisors during the course of orthodontic treatment.

Indications for orthodontic treatments are in constant augmentation in the adult population. Patients want the shortest possible treatments. Alveolar corticotomies speed up the tooth movement in comparison to conventional orthodontic treatments, therefore decrease treatment duration.This technique consists in the surgical section of cortical bone that leaves the medullar bone uninjured. The biological effects of corticotomies rely on decreasing medullary bone density and increasing bone remodelling activity (RAP regional acceleratory phenomenon).We are currently testing this combined approach of alveolar corticotomies and orthodontic treatments on a pig model with special attention given to potential secondary effects on pulp vitality, dental root morphology and length.We also present here two adult patients with malocclusion cases who underwent alveolar corticotomies as part of their surgical-orthodontic treatments.These experimental and clinical preliminary studies confirm that corticotomy requires a shorter time of orthodontic movement. Our clinical results showed that this technique resolves malocclusion at least twice as fast as conventional orthodontic treatment.No secondary effects of corticotomies on pulp vitality dental root morphology were observed.

Does the technique employed create a specific post-treatment arch form? To answer this question we compared the arches at the close of treatment of patients treated by the Tweed technique with those treated by the Damon technique. We analyzed 78 plaster models using the computer program. Procluso in an attempt to standardize assessment of the arch forms. The post-treatment arch form surimposition showed no differences between arches of patients treated by Tweed therapy and arches of patients treated by Damon technique. Regression and discrimination tests were used in order to calculate and visualize singles differences in form between the three samples used in our study (patients treated by Tweed therapy without extraction, patients treated by Tweed therapy with extractions and patients treated by Damon therapy without extractions). This is the outcome of differences located at the level of position of teeth related to the shape of dental arch form. On the other hand dental arch forms are nearly similar in the various samples. Arch form was just more harmonious, more well rounded with good continuity of buccal surfaces when practitioners used pre-adjusted Damon brackets compared to braces with no built-in torque employed in Tweed therapy.
