Description

Technical Field

[0001] The invention belongs to the technical field of oral medical appliances, and in particular relates to a bracket-free invisible brace adapter suitable for obstructive sleep apnea. Background Art

[0002] Obstructive sleep apnea (OSA) is a common sleep disorder characterized by repeated pauses in breathing and / or decreased airflow during sleep. This can lead to serious health problems such as daytime sleepiness, fatigue, and increased risk of cardiovascular disease.

[0003] Although continuous positive airway pressure (CPAP) is the primary treatment for obstructive sleep apnea, a considerable number of patients give up treatment due to its poor comfort. Mandibular advancement therapy is an effective treatment for mild to moderate obstructive sleep apnea, especially when patients cannot cooperate with CPAP, it can be used as an alternative treatment. Mandibular advancement therapy helps relieve patients' symptoms of obstructive sleep apnea and improve their sleep and quality of life. Mandibular advancement therapy for obstructive sleep apnea belongs to the category of oral professional treatment and is generally performed by an orthodontist. The treatment content is to customize a personalized mandibular advancement device according to the patient's oral and maxillomandibular conditions, increase the airway volume and ventilation by advancing the mandible and increasing the vertical distance of the mandible, and relieve apnea caused by airway obstruction during sleep. There are also non-personalized finished mandibular advancement devices, but customized mandibular advancement devices are more conducive to physicians designing, monitoring, and evaluating the treatment process and efficacy according to individual patient conditions. When the patient sleeps at night, the mandibular advancement device is worn in the mouth. The advancement device between the upper and lower jaws forces the mandibular dentition and mandible to extend forward and be in a forward position relative to the maxillary dentition and maxilla, thereby achieving the treatment goal of advancing the mandible.

[0004] More than 900 million adults aged 30-69 suffer from OSA worldwide; due to factors such as lack of knowledge about OSA and regional differences in medical levels, 80%-90% of OSA patients do not receive timely diagnosis and treatment. With people's increasing attention to oral health and their yearning for a better life, more and more patients with obstructive sleep apnea are seeking treatment in oral medical institutions due to oral malocclusion problems, and orthodontists are faced with patients suffering from both obstructive sleep apnea and malocclusion. At the same time, bracketless invisible braces are both comfortable and beautiful, and their acceptance and popularity in orthodontic clinical diagnosis and treatment are also increasing. However, there is currently no transition system that is compatible with the combined application of obstructive sleep apnea mandibular advancement devices and bracketless invisible braces.

[0005] The mandibular advancement device for sleep hypopnea and the bracketless invisible braces are each a separate system. The mandibular advancement device for obstructive sleep apnea is usually customized for dentition without tooth displacement, while malocclusion correction requires constant adjustment of the position of misplaced teeth to achieve the correction goal of beautiful and neat dentition and coordinated occlusal function. The mandibular advancement device for obstructive sleep apnea cannot be used in the mouths of patients with obstructive sleep apnea and malocclusion at the same time as the bracketless invisible braces. Patients with obstructive sleep apnea generally use the mandibular advancement device when they sleep at night, and cannot wear bracketless invisible braces at this time; shortening the wearing time of the invisible braces will have an adverse effect on the treatment process and treatment effect of malocclusion, and cannot better guarantee the treatment needs of patients. Patients who receive bracketless invisible braces and suffer from obstructive sleep apnea are in urgent need of an adapter system that can integrate the mandibular advancement treatment device into the invisible braces, so that patients can wear the invisible braces around the clock and simultaneously use the mandibular advancement treatment device at night to treat obstructive sleep apnea.

[0006] It can be seen that there is currently no correction system that can effectively combine the treatment device for mandibular advancement of obstructive sleep apnea patients with bracketless invisible correction. Currently, obstructive sleep apnea patients usually wear customized mandibular advancement treatment devices at night, but they cannot wear invisible braces at the same time to treat malocclusion. Summary of the invention

[0007] In order to solve the defects of the above-mentioned prior art, the present invention proposes a conversion system for mandibular advancement treatment combined with bracketless invisible correction for patients with obstructive sleep apnea. The conversion system can be placed on invisible braces, effectively combining the mandibular advancement device for obstructive sleep apnea and the bracketless invisible correction. Patients can wear invisible braces continuously during the day and at night, and at the same time, use the mandibular advancement device in conjunction with the invisible braces at night through the conversion system to improve the symptoms of obstructive sleep apnea, which has a good application prospect in clinical practice.
