Background. Obstructive sleep apnea (OSA) is a condition that affects a patient’s ability to sleep normally, predisposing them to many risks and reduced quality of life. Myofunctional therapy has been proven to increase the airway space according to literature. Aim. To report the effects of AdvanSync2 Class II corrector in the management of 3 orthodontic patients who reported sleeping difficulties due to breathing problems and retrognathic mandible. Case presentation. Three patients reported to Department of Orthodontics and Dentofacial Orthopaedics with Class II malocclusion associated with sleep apnea requiring treatment. Clinical examination revealed a retrognathic mandible with airway constriction in all subjects. A non-extraction approach using an AdvanSync2 Class II corrector (Ormco Corp, Glendora, Calif) with fixed appliances was considered. Lateral cephalometric records were obtained at three stages: pre-treatment, post functional and prefinishing/post treatment. The airway was divided into 3 parts in the lateral cephalogram: velopharynx, hypopharynx and glossopharynx. The most constricted part of the airway was noted. Pre and post treatment lateral cephalograms were compared to assess the changes in airway dimensions after using AdvanSync2. Significant enhancement in airway dimensions was noted in all three parts (velopharynx, glossopharynx and hypopharynx) in all patients. Conclusion. Airway assessment is an important aspect in orthodontic diagnosis. Use of the AdvanSync2 Class II corrector in combination with fixed orthodontic appliances enhanced quality of life in Class II patients by improving airway dimensions. This approach can be recommended in the management of mild to moderate Class II malocclusions associated with mandibular retrognathism and airway constriction.
Context: Smile aesthetics is one of the major goals to be achieved after orthodontic mechanotherapy as it visibly displays the results of orthodontic treatment. Although orthodontic retainers aid in maintaining post-treatment occlusion, soft tissue function and aesthetics, appropriate knowledge of smile changes with age can help orthodontists to obtain stable and aesthetically appealing treatment results. Aim: To assess and quantify soft tissue changes in the upper lip in vertical dimension at both repose and maximum smiling and to evaluate changes occurring with the smile index and upper lip with age and sex in subjects of Indian origin. Settings: Department of Orthodontics and Dentofacial Orthopaedics, Army College of Dental Sciences, Secunderabad, Telangana, India. Design: Observational study Methods and Materials: A total of 160 volunteers (80 males and 80 females) selected and were divided into 4 groups according to age and were further divided into 2 sub-groups according to gender. Thirteen measurements of relaxed and smiling upper lip were taken with a calibrated metal ruler and divider directly on the subjects. Statistical Analysis Used: Analysis of variance (ANOVA) was done followed by post hoc test to determine which groups were significant from others. Levene's test was done to assess equality of variance and t-test for equality of means was done. Results: Statistically significant results were obtained in between groups and sub-groups for parameters like smile index, upper lip elevation while smiling and smile pattern in males and females changing with increase in age. Conclusions: High smile patterns with more vertical smile are more common among females and low smile patterns are more common among males. With age, the smile tends to be more horizontal in both genders.
