Description

Maxillary edentulous tray with aesthetic forenotice function

Technical Field

The utility model relates to a tray for obtaining upper jaw impression of edentulous jaw patient especially relates to the front teeth aesthetic information who records the patient when the patient first visits the doctor, provides the edentulous jaw tray of reference for later stage tooth arrangement.

Background

At present, the precision of the complete denture mold taking and the simplification of the process are one of the key points of the complete denture development, and if the accuracy of the impression can be improved as much as possible when the initial impression is obtained, the fixture and the stability of the denture manufactured in the later period can be improved. Furthermore, with the increasing aesthetic requirements of the public, many edentulous patients desire to restore the state before tooth loss, and in addition to being able to chew with comfort, the patients desire a new denture with a beautiful and natural appearance, which puts higher demands on the complete denture we make. In the conventional process of making a complete denture, after taking a secondary impression, teeth are tried to be arranged, and a wax pattern is tried to be worn in the mouth of a patient to determine whether the arranged teeth meet the aesthetic requirements of the patient, which increases the number of times of patient visits and also complicates the adjustment process. At present, the record of aesthetic information is lost during the process initial diagnosis of the digital complete denture, and the adjustment and modification in the subsequent process are difficult, so the number of times of the patient's treatment is increased. This patent is made to solve the above problems. The application of this patent just obtains the reference of aesthetic tooth arrangement when the patient visits for the first time, facilitates for the artificial tooth preparation of later stage, also provides new preparation thinking for the complete denture flow of digitization.

SUMMERY OF THE UTILITY MODEL

The utility model provides a tray for recording aesthetic information of upper jaw anterior teeth while preparing a primary impression, which solves the complex and fussy problem of the complete denture preparation process.

Solve the technical problem of the utility model is that:

(1) this novel tray comprises the upper jaw tray of different models, artifical tooth and jaw side handle, regards as the handle of no tooth jaw tray with 6 upper jaw anterior teeth that arrange well, and these 6 artifical teeth select for use the model commonly used clinically, match the tray of not equidimension model.

(2) The trays are different in type, size and grade, and have different lip fullness. For different edentulous patients, the appropriate tray is selected with reference to the arch size and face type, lip shape, etc. The tray is divided into a large (L), a medium (M) and a small (S) model, and the proper model is selected according to the size of the dental arch of a patient. Each model is divided into three grades of 1, 2 and 3, and the different labial fullness corresponding to each grade are ordered to be 1<2< 3; the size of the labial fullness is determined by the angle of the front side of the tray and the inclination angle of the arrangement of the artificial teeth, and the greater the inclination of the artificial teeth labial is, the greater the labial fullness is. The artificial teeth under each model and level are different in size so as to match different dental arch sizes, and the artificial teeth under different models and levels are divided into three shapes, namely a square shape, an oval shape and a pointed shape so as to match patients with different face types, and a more attractive artificial tooth form is selected.

(3) The position of the tray in the mouth is adjusted according to the position of the anterior teeth, and the anterior occlusal plane is parallel to the connecting line of the pupils; the fullness of the labial side conforms to the face shape of the patient; aligning the maxillary arch midline with the facial midline; the ratio of cuspid spacing to smile width (distance between left and right corners of mouth at smile) (cheek-gap index) is within the aesthetic reference range; when the jaw is stopped, the incisal margin of the upper anterior teeth is exposed for 2mm below the lips; the exposed amount of the dental crown in smiling meets the aesthetic requirement. The impression material space is reserved by adding a stop point on the tray tissue surface.

(4) The palate side handle is positioned on the palate side of the upper middle incisor and the lateral incisor and is used for holding when taking a model; and (3) when the mold is taken, the position of the tray is consistent with the position after the tray is placed into the opening and the position after the tray is adjusted.

(5) After the impression taking is finished, the impression and the artificial tooth are digitally scanned, so that aesthetic tooth arrangement information and alveolar ridge forms are recorded. The impression is recorded by digital scanning, or the relation record of the front tooth arrangement is obtained by copying the false tooth, so as to provide reference for the final false tooth.

Adopt above-mentioned scheme, compare with prior art, the utility model discloses it is following showing the progress to have:

1. because the utility model discloses just let the patient foresee the aesthetic effect of later stage artificial tooth in advance when first impression taking, consequently have the advantage that the aesthetic forecast was reported in advance.

2. Because the utility model discloses an acquire anterior teeth aesthetic information when making the primary impression, consequently convenient and fast has improved the efficiency of treatment and preparation more.

3. Because the utility model provides a tray of various models, the doctor clinical use of consequently being convenient for is applicable to different patients, has improved work efficiency.

4. Because the artificial tooth of the utility model has diversity and is suitable for patients with different face types, the application range is wide.

5. Because the utility model discloses reduce the process of seeing a doctor that a patient acquireed aesthetic information, consequently improve the patient and see a doctor and experience.

6. Because the utility model has the advantages of simple structure, the processing ease consequently provides more swift and accurate impression taking process for the doctor.

7. Because the material of the utility model adopts the thermoplastic resin material and is soaked and disinfected by glutaraldehyde, the material can be reused after disinfection.

8. Because the material of the utility model adopts the thermoplastic resin material, the material becomes soft at the temperature of more than 90 ℃, thereby being capable of carrying out thermoplastic modification according to clinical needs.

Detailed Description

When a patient without the upper jaw is in a first visit, the size of the upper jaw dental arch of the patient is observed, and the novel tray with the proper size is selected to be placed into the mouth; observing the fullness of the labial sides, and selecting the trays with the same type and proper grade; observing the face shape of the patient, and selecting the square, oval or pointed artificial tooth to adapt to the face shape of the patient. The position of the tray in the entrance needs to be adjusted according to the position of the front teeth, the impression material space is reserved by a mode of adding dead points on the tissue surface of the tray, and the fullness can be changed by a mode of adding wax on the lip side of the tray, so that the fullness satisfactory for a patient is obtained. When the mold is taken, after the tray is placed in the mouth, the front occlusion plane is parallel to the pupil connecting line; the fullness of the labial side conforms to the face shape of the patient; aligning the maxillary arch midline with the facial midline; the proportion (tooth cheek gap index) of the distance between the cuspids and the width of the smile (the distance between the left and right corners of the mouth at the time of smiling) is proper; when the jaw is stopped, the incisal margin of the upper anterior teeth is exposed for 2mm below the lips; the exposed amount of the dental crown in smiling meets the aesthetic requirement. And after the position of the tray placed in the patient's mouth is stable, placing impression material on the surface of the tray, placing the tray into the mouth to obtain the impression of the patient, and finishing the mould taking process of the first visit.
