Description
Technical Field
The utility model relates to the field of medical auxiliary devices, in particular to a digital individual impression tray suitable for cleft lip and palate neonates.
Background
Congenital cleft lip and palate, which involves soft and hard tissues of the maxillofacial region, damages the oromandibular function and normal growth and development of the maxillofacial region and is accompanied by complex dental deformity, seriously affects the facial appearance and mental health of the children, and needs multiple disciplines to cooperate in different time periods, namely the internationally recognized cleft lip and palate 'sequence treatment' at present.
The pre-operation correction of cleft lip and palate of a newborn is the first link of sequence treatment, namely PNAM treatment, and the shaping is carried out on the external nasal cartilage while the alveolar process deformity is corrected. The specific process of PNAM treatment is that the upper jaw impression is taken as soon as possible after the child is born, the plaster model is poured, the intraoral plastic plate is made, the elastic adhesive tape is used for applying force accurately and directly, the position of the bone segment is adjusted by selective soft lining and grinding during the re-diagnosis, and the nasal support is added in due time to reduce the malformation of nasal cartilage and soft tissue. The PNAM treatment effect is very good, but the initial die-taking operation is very difficult, the neonate has small operable space and certain danger in die-taking, currently, heavy silicone rubber die-printing materials are generally adopted to reduce the risk of aspiration, the time is about three minutes, but no special tray for the neonate with cleft lip and palate exists, the current common mode is to grind and change the minimum tray for clinical application and then take the die, the obvious defect exists, the neonate with cleft lip and palate on one side can be too wide to be plugged into the oral cavity of a patient to cause the failure of die-taking, the incompleteness or the damage to the oral angle mucosa tissue of the patient to cause bleeding, the neonate with cleft lip and palate on two sides can only take half of the maxillary bone due to the anterior protrusion of the maxillary bone, the difference between the shape and the normal maxillary bone shape is too large, the die is unsuccessful to cause the inaccurate making of the subsequent plastic plate and the incorrect force application, affecting the therapeutic effect.
In order to increase the success rate of taking a model and make the impression more accurate, researchers have conducted multiple studies at present, and try to adopt intraoral scanning to a patient with unilateral cleft lip and palate to directly form a digital model to manufacture a shaping plate, but the oral space of an infant patient is limited, the cleft lip and palate causes too much undercut, details cannot be scanned, and therefore intraoral scanning of a newborn can only stay in the research stage. The scholars shoot CBCT for the neonate and then carry out three-dimensional reconstruction, 3D prints a maxilla model and then makes an oral plastic plate, and the conventional shooting of CBCT for the neonate with cleft lip and palate can increase radiation risks. Therefore, the mold-taking tray becomes a bottleneck problem of the PNAM treatment, and no simple and effective solution is recognized at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the problems and particularly provides a digital personalized impression tray suitable for cleft lip and palate neonates.
The utility model provides a digital individual impression tray suitable for cleft lip and palate neonates, which is characterized in that: according to the malformation type of the children with cleft lip and palate, different half-side trays are adopted for splicing and inserting to form a complete upper jaw tray;
each half-side tray comprises a tray and a handle, wherein the tray and the handle are provided with concave parts on the left tray, the corresponding convex parts are designed on the right tray by utilizing the thickness of the tray, the concave parts and the convex parts are clamped by utilizing the elasticity of materials, and the concave parts and the convex parts are combined to form a complete tray; the tray is provided with small holes to allow the printed film to overflow and increase the retention.
Because the children with cleft lip and palate are divided into a single left side, a single right side and two sides, the half-side tray is divided into a left side crack structure, a right side crack structure, a left side complete structure and a right side complete structure.
Patients with unilateral cleft lip and palate use a half-lateral fracture tray plus a half-lateral complete tray, and patients with bilateral cleft lip and palate use a left-lateral fracture tray plus a right-lateral fracture tray. According to the measurement and analysis of the existing cleft lip and palate model, the width of the tail end of the width of the half-side tray is 25mm, the length of the half-side tray is 40mm, the depth of the half-side tray is 13mm, and the moving length of the edge of the crack is 20 mm.
The utility model has the advantages that:
the digital individual impression tray suitable for cleft lip and palate neonates, provided by the utility model, has the advantages that the vestibular groove edge is trimmed compared with the traditional tray, the digital individual impression tray is more suitable for the oral vestibular groove of a cleft lip and palate patient, and the mould taking is more convenient and accurate. According to the type of cleft lip and palate patients, the digitalized individual tray for cleft lip and palate can be combined in a half-side form to meet various cleft lip and palate forms.
