Definitions

• the present invention relates to a dental orthosis, particularly for the therapeutic treatment of Obstructive Sleep Apnea Syndrome (OSAS).
• OSAS Obstructive Sleep Apnea Syndrome
• OSA is a disease defined by a series of episodes of obstructions, total or partial, leading to the total or partial cessation of breathing during sleep, and more specifically to either hypopnea, that is to say a decrease in airflow, ie apnea, ie the cessation of airflow or ventilation.
• Apnea is usually defined by a stop of 10 seconds or more of airflow and hypopnea by at least a 50% decrease in airflow for at least 10 seconds.
• the main symptoms related to OSA and therefore to apnea and / or hypopnea are hypersomnolence, memory problems, difficulty concentrating, behavioral disorders, depressive syndromes, libido disorders, automatic behaviors and the risk of traffic accidents.
• OSAS is associated with cardiovascular excess mortality as it is likely to lead to left and / or right ventricular failure, cardiac arrhythmias, cerebrovascular accidents and systemic arterial hypertension and / or pulmonary and ischemic heart disease.
• the hypopneas are also accompanied by microreveils, disorganizing all the sleep of the individual and leading to a fragmentation of sleep, which is no longer restorative because of these interruptions in airflow and episodes of hypoxemia that result hence a feeling of fatigue in the patient.
• this device is relatively bulky, expensive and noisy, resulting in noise that is difficult to manage for the immediate surroundings of the user.
• Surgical procedures to correct organic defects that may lead to OSA may also be considered, such as nasal surgery, soft tissue surgery (tonsillectomy, uvulopalatopharyngoplasty, pharyngotomy, basiglossectomy), or bone surgery, such as bimaxillary surgery, hyoid surgery, or genital transposition.
• This modification also affects the craniofacial skeleton.
• OSA anatomical abnormality
• craniomaxillofacial abnormalities and retromandibulia for example the position of the maxillary, the angulation of the base of the skull and the height of the face.
• OSA The pathophysiology of OSA is unclear and involves several factors such as changes in upper airway anatomy and resistance as well as control of pharyngeal dilator muscle tone during sleep.
• dental prostheses have been proposed propelling the mandible in the context of the treatment of OSAS, these prostheses being intended to be worn at night.
• These dental prostheses are intended to prevent the patient from exerting muscle forces on the soft tissues of the airways superior, including tongue, pharynx, velum and vocal cords.
• Prostheses according to the prior art generate a visco-elastic muscle reaction of the mandibual retropulsors.
• the present invention proposes to solve the problems related to the prior art with the aid of an easily usable prosthesis, inexpensive, easily adaptable, easy to manufacture with simple elements, having no side effects associated with prostheses according to the prior art (dental pain for example), to effectively treat patients with OSAS with high success rates and favoring muscular involvement in mandibular advancement.
• the present invention relates to a dental orthosis comprising upper cooperation means adapted to cooperate with the upper jaw and lower cooperation means adapted to cooperate with the lower jaw, characterized in that said orthosis present means capable of inducing a mandibular advancement and more specifically the lower cooperation means comprise means able to exert pressure on the chin spines of said lower jaw.
• the pressure means are in the form of at least one bracket with a rounded end covered by a plate in a non-allergenic substance and made of a steel wire.
• the cooperation means are made of a non-allergenic substance, in particular an acrylic resin.
• the lower cooperation means have means for adjusting the mandibular propulsion consisting of a cylinder of adjustable length.
• the upper cooperation means comprise fastening means on the upper jaw constituted by fastening means on at least one molar in the form of a Adams-type hook.

• - Figure 6 shows a perspective view of three-quarters of the orthosis according to the invention fixed on the upper jaw.
• Figure 1 shows a front view in perspective of the orthosis according to the invention placed in a jaw of a patient.
• the orthosis according to the invention 1 has upper and lower cooperation means 2 3 capable of cooperating with the maxillary, respectively upper 4 and lower 5 of a patient.
• the upper and lower cooperation means (2, 3) are in the form of a gutter 6 in which the dentition, respectively, of the maxillary upper 2 and lower 3 is able to support and cooperate.
• the cooperation means (2, 3) are in a generally semicircular or horseshoe shape.
• FIG. 1 shows cooperation means (2, 3) with an open outer face, that is to say that once the teeth have been resting on the channel 6, then the outer face of the teeth is not covered by the cooperation means (2, 3) or only partially.
• the upper and lower cooperation means (2, 3) have digs or internal engravings of complementary shape to the dental crown of the teething respectively of the upper maxillary 4 and lower 5, these digs or etchings being advantageously made from of maxillary castings 4 and lower 5.
• the dental crown can fit totally or partially into the gutter 6, thus allowing fixed retention of the cooperation means (2, 3) on the dental arches.
• the cooperation means (2, 3) are made of a non-allergenic material, in particular an acrylic resin.
• Figure 2 shows a side view of the orthosis according to the invention placed in a jaw of a patient.
• fixing means 7 of the orthosis 1 on the upper maxillary 4 are provided in the upper cooperation means 2.
• the fixing means 7 are in the form of hooks 8 cooperating with the patient's upper dental arch.
• the dentition of each individual is composed of a double pair of incisors (9a, 9b, 9c, 9d), a pair of canines (10a, 10b), a double pair of premolars (11 a, 11b, 11c, 11d) and then molars (12a, 12b), this dental distribution being found both for the upper maxilla 4 than for the lower jaw 5.
• the fastening means 7 shown in FIG. 2 consist of fastening means using at least one premolar 13 and fixing means on at least one molar 14
• the fixing means on at least one molar 14 are in the form of a hook 8 commonly known as Adar's hook.
• the so-called Adams hook 8 is thus advantageously made of a hard steel wire surrounding a molar (12a, 12b) and whose two ends are encompassed in the upper cooperation means 2 and more precisely in the constituent resin mass of these means of cooperation 2.
• the fixing means of the orthosis 1 with the aid of at least one premolar 13 is in the form of an arm 15 advantageously made of an ascending steel wire and able to be inserted between the two premolars (11). a, 11 c) of the maxilla 4.
• the free end of the arm 15 has a ball or bulge material so as not to notch or irritate the gingiva at the free space between the two premolars (11a, 11b, 11c, 11d).
