RU177843U1 - INDIVIDUAL KAPPA FOR DIRECT DENTAL ORTHOPEDIC REHABILITATION OF POST-RESECTIVE DEFECTS - Google Patents

Abstract

The utility model relates to medicine, namely to dentistry, and can be used for direct dental orthopedic rehabilitation of post-resection defects. The technical result is achieved by creating an individual temporary mouth guard for direct dental orthopedic rehabilitation of post-resection defects, which is an individual jaw plate made of transparent bioinert material consisting of a base, a retention fragment, mechanically holding located on the remaining alveolar ridge with teeth, and a resection fragment imitating the missing dentition using self-hardening plastic, which is applied directly to the operating table.

Description

The utility model relates to medicine, namely to dentistry, and can be used for direct dental orthopedic rehabilitation of post-resection defects.

Known combined protective palatine plate, consisting of two parts, the first of which covers the dentition and is made of hard plastic, the second is the region of the palate and is made of soft plastic (Guide to surgical dentistry. / Ed. By A.I. Evdokimov. - M .: Medicine, 1972. - p. 458, 459). The disadvantage of this invention is the lack of visual control over the state of a post-resection defect; Difficult imposition and fixation in the prints of the teeth in connection with the implementation of the part covering the dentition of hard plastic.

Known protective palatine plate with an occlusal surface without a dentition made of celluloid according to A.I. Betelman (1965), from quick-hardening acrylic plastic according to Z.N. Urban et al. (1960), Ya.M. 3barge (1963), E.S. Iroshnikova (1971), two-layer construction according to G.I.Semenchenko (1972), which overlaps the defect that forms, loosely adheres to the flaw, holds the bandage, and also protects wound surface from mechanical stress and infection from the oral cavity. The disadvantages of these inventions are the complexity and length of production, the inability to replenish the resected dentition.

For the prototype, the device that is closest in technical essence and achieved effect is selected, which represents a protective palatine plate for protecting joints and tampons from external influences from the oral cavity, immobilizing transplant and / or implant material, mucoperiosteal flaps in a new position, holding tampons and forming palatine arch (US Pat. RU No. 2326622, А61С 13/107, 12/01/2006). The disadvantage of this invention is the lack of replenishment of a fully or partially removed dentition.

Problem: increasing the effectiveness of direct orthopedic treatment and improving the quality of life of patients with post-resection defects of the jaw.

The technical result is achieved by creating an individual temporary mouthguard for the direct orthopedic treatment of post-resection defects, which is an individual jaw plate made of a transparent bioinert material, consisting of a base, a retention fragment, mechanically held on the remaining alveolar process with teeth, and a resection fragment imitating an absent dental row with self-hardening plastic, which is applied directly to the operator ionic table.

The essence of the proposed device is the manufacture of an individual mouthguard, consisting of a base [1], a retention fragment [2], fixed on the remaining alveolar process with teeth, and a resection fragment [3] that imitates the missing dentition [4] using self-hardening plastic.

To make an individual mouthguard, an impression is taken from the patient's jaw using an alginate mass and the model is cast from super gypsum before surgery. Phantom preparation of the gypsum model is carried out. Next, a plate of bioinert material (Duran, Placas para Plastificadoras a vacuo) is heated to a plastic state and, using a vacuum former (Plastvac P7), the gypsum model of the jaw is pressed into a snug fit and then cooled. With the help of self-hardening plastic on the made mouth guard, the crown parts are imitated in the tooth prints to be removed. Processing and polishing of an individual temporary mouth guard. Then it is applied in the patient’s oral cavity directly on the operating table.

For a better understanding, the proposed kappa is depicted in a general view in FIG. 1, where p. 1 is the basis, p. 2 is the retention fragment, p. 3 is the resection fragment, p. 4 is the artificial teeth.

The transparency of the manufactured individual temporary mouthguard provides the ability to visually monitor the state of the post-resection defect.

A clinical study was conducted in 8 patients with post-resection defects who made individual temporary mouth guards for the jaw.

Example. Patient V., 32 years old, was admitted to the clinic of orthopedic dentistry with a diagnosis of adenocarcinoma of the sky on the right with the upcoming resection of the right maxillary bone with teeth 1.7-1.1.

Complaints: education in the sky on the right.

Objectively: the face is symmetrical, nasolabial folds are moderate, regional lymph nodes without pathology. A neoplasm in the sky on the right is 3 × 4 cm in size, the mucous membrane in the area of the defect is pale, moderately moist.

Treatment. Inspection, examination of the patient. An impression of the upper jaw of the patient was obtained using an alginate impression mass. A gypsum model of the jaw was made. A phantom preparation of the gypsum model was performed. Next, a plate of bio-inert material Placas para Plastificadoras was heated to a plastic state and, using a Plastvac P7 vacuum former, the gypsum model of the upper jaw was pressed to a snug fit and then cooled. With the help of self-hardening plastic on the made mouth guard, tooth crowns 1.7 - 1.1 imitated their crown parts. Made processing and polishing of an individual temporary mouth guard. Then it was superimposed in the patient's oral cavity in the department of maxillofacial surgery.

Thus, when using the proposed device, an increase in the effectiveness of direct orthopedic treatment and an improvement in the quality of life of patients with post-resection defects of the jaw are achieved.

The proposed device in comparison with analogues has the following advantages:

1. Simplicity of manufacturing in the shortest possible time.

2. Profitability.

3. Hypoallergenicity of the materials used.

4. Ensuring aesthetic function by simulating a missing dentition.

5. The density of fixation in the oral cavity due to the remaining teeth.

The proposed device can be recommended in clinical practice for dental orthopedic rehabilitation of patients with post-resection defects.

Claims (1)

An individual mouthguard for direct dental orthopedic rehabilitation of post-resection defects, which is an individual jaw plate made of a transparent bioinert material, consisting of a base, retention and resection fragments, characterized in that the retention fragment provides tooth fixation on the remaining teeth using the imprints of teeth on the mouth guard , and the resection fragment imitates the missing dentition and part of the palate using a self-hardening plastic a cis filling in the prints of the teeth and the base area in the projection of the defect.
