Abstract
The utility model relates to an edentulous space keeper, including belt ring, supporter and stay head, the inner circle shape of belt ring and the peripheral profile phase-match of the tooth of patient's edentulous clearance side far away, the stay head wholly is the tooth that the inboard shape of C type and stay head and patient's edentulous clearance side near corresponds profile phase-match, and belt ring and stay are through supporter joint support between the head. The utility model discloses simple structure can fully laminate with the tooth that the patient lacks the tooth clearance both sides, is favorable to carrying out the accuracy to lacking the tooth clearance and keeps.
Description
Technical Field
The utility model belongs to the technical field of the tooth clearance keeps, especially relate to a missing tooth clearance keeps ware.
Background
In the process of child development, because of the problems of acquired diseases such as decayed tooth, periodontitis and periapical periodontitis and congenital diseases, the milk teeth of children patients are lost too early, but because the permanent tooth germ still develops, the permanent tooth germ has no sign of eruption. If the treatment is not carried out, the teeth on the two sides of the edentulous gap of the patient child tend to incline towards the edentulous gap and possibly influence the eruption position of the permanent teeth, so that the permanent dentition deformity causes the jaw development deformity. Therefore, it is necessary to maintain the gap at the edentulous position with an auxiliary tool.
Disclosure of Invention
The utility model aims to solve the technical problem that a missing tooth clearance keeps ware is provided, simple structure improves the laminating degree of keeping ware and missing tooth clearance both sides tooth, is favorable to keeping the missing tooth clearance accuracy.
The utility model provides a technical scheme that its technical problem adopted provides an edentulous space keeper, including belt ring, supporter and chaplet, the inner circle shape of belt ring and the peripheral profile phase-match of the tooth of the side far away in patient's edentulous space, the whole inboard shape that is C type and chaplet of chaplet corresponds side profile phase-match with the tooth of the side near the side in patient's edentulous space of chaplet, through supporter joint support between belt ring and the chaplet.
The belt ring, the supporting body and the supporting head are of a titanium alloy 3D printing integrated structure.
The support body is two parallel support pieces.
The support body is arc-shaped along the length direction.
The position of the belt ring and the supporting head matched with the teeth at two sides of the edentulous gap of the patient is lower than the occlusal surface of the teeth by more than 2 mm.
The supporting body is higher than the gum surface of the patient by more than 1 mm.
Advantageous effects
The utility model discloses in, the tooth peripheral profile phase-match of ring inner circle shape and patient edentulous clearance one side, can paste and bond fixedly with the tooth of patient edentulous clearance far-in side, the inboard shape of chaplet corresponds side profile phase-match with the tooth of patient edentulous clearance opposite side, can with the tooth laminating of patient edentulous clearance nearly medial side, supports through the supporter between, can keep the edentulous clearance. Therefore, the utility model discloses simple structure can fully laminate with the tooth that the patient lacks the tooth clearance both sides, is favorable to carrying out the accuracy to lacking the tooth clearance and keeps.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
An edentulous space holder as shown in fig. 1 comprises a ring 1, a support body 2 and a stay 3.
The shape of the inner ring of the belt ring 1 is matched with the peripheral outline of the tooth at the far middle side of the patient edentulous gap, the support head 3 is integrally C-shaped, the shape of the inner side of the support head 3 is matched with the outline of the corresponding side of the tooth at the near middle side of the patient edentulous gap, and the belt ring 1 and the support head 3 are connected and supported through the support body 2. The support body 2 is two parallel support pieces which are arc-shaped along the length direction.
The structural model of the belt ring 1 and the supporting head 3 is designed and formed by means of genomatic software according to the appearance of the tooth impression, and the belt ring 1, the supporting body 2 and the supporting head 3 are of a titanium alloy 3D printing integrated structure. The belt ring 1 is designed according to the tooth model at the far middle side of the edentulous gap of the patient child, is fully attached, and has the printing width of 0.3 mm. The supporting head 3 is designed according to the tooth model of the patient infant on the near-middle side of the edentulous gap, can be fully attached, and has the printing width of 0.3 mm. The position of the belt ring 1 and the supporting head 3 matched with teeth at two sides of the edentulous gap of the patient is lower than the occlusal surface of the teeth by more than 2mm, and the supporting body 2 is higher than the gingival surface of the patient by more than 1 mm.
The edentulous space retainer has simple structure, can be fully attached to teeth on two sides of an edentulous space of an infant, and is favorable for accurately retaining the edentulous space.
