Embodiment Construction

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and in combination with specific embodiments.

[0018] The embodiment of the present invention is a bonding-retained occlusal splint, in this embodiment:

[0019] like figure 1 and figure 2 As shown, the bonded and retained occlusal plate 1 forms a depression 2 inwardly, covering the occlusal surface of the patient's upper and lower jaw dentition 3. A gap is left, and the gap is filled with adhesive, and the occlusal plate is bonded and fixed to the patient's tooth surface through the adhesive. Through the bonding and retention design of the occlusal plate, the occlusal plate can be fixed on the patient’s tooth surface without trauma, which saves the cumbersome operation of using steel wires or screws for the occlusal plate in the prior art, and saves operation time. It is simple and convenient, and especially avoids the risk of damaging the tooth germs of inf...

Abstract

The invention discloses a bonded and fixed bite plate for stabilizing an intermaxillary relationship to guide a temporal-mandibular joint reconstructive surgery. The bite plate forms a recess inwards and coats occlusal surfaces of full dentitions of upper and lower jaws of a patient; the form of the recess is matched with the appearance of the tooth surface of the patient, and a gap is reserved between the recess and the tooth surface of the patient; and the gap is filled with a bonder and is bonded and fixed with the tooth surface of the patient. The bite plate is designed through a digital technology and is integrally molded by adopting light-cured resin; the thickness is determined according to the clearance between the dentitions of the patient, the coating depth on the tooth surface of the patient is 1.5mm, and the bite plate extends out of a lip and cheek side and a tongue and palate side of the tooth surface of the patient for at least 1mm; and the bite plate is bonded and fixed with the tooth surface of the patient through a glass ion binder which is 0.3mm in thickness. The bonded and fixed bite plate is suitable for the patient with mouth opening limitation; and the bite plate is bonded and fixed on the tooth surface of the patient, so that intraoperative operation of steel wire tying or screw retention is omitted, the trauma to an oral cavity of the patient is reduced, and especially the trauma to dental germ of an infant patient is avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a bonded and retained dental splint. Background technique [0002] Temporomandibular joint ankylosis and condylar idiopathic resorption are the two most common diseases in the temporomandibular joint area, which are difficult to treat and have high risks, and these patients are often accompanied by jaw deformities. These conditions are generally treated with temporomandibular joint reconstruction surgery. In joint reconstruction surgery, it is necessary to position the patient's occlusion to stabilize the position of the patient's mandible, thereby completing the reconstruction of the temporomandibular joint. [0003] The traditional method of stabilizing the occlusion is to obtain the patient's dentition model before the operation, and make the occlusal plate according to the final occlusal position of the patient's jaw. However, patients with temporomandibular joint ankylosi...
