Description

Space occupying body for maintaining missing tooth space in orthodontic treatment process of missing tooth patient

Technical Field

The utility model relates to an occupying body for maintaining missing tooth space in the orthodontic treatment process of a patient with missing tooth, belonging to the technical field of medical products.

Background

Patients with tooth loss and malocclusion are frequently seen in clinic, and the number of patients with congenital tooth loss is more. Such patients often require orthodontic treatment to correct malocclusions and to align their teeth. If too large missing tooth space exists and cannot be closed through orthodontics, the size of the missing tooth space needs to be reasonably controlled, and a proper space is reserved for subsequent missing tooth restoration (such as dental implant).

Currently, when a patient suffering from tooth loss and malocclusion is clinically faced, orthodontists mostly use a fixed straight wire arch correction method to align dentitions due to relatively complicated treatment. For the tooth position that needs to keep certain clearance, in order to avoid adjacent tooth to remove and lead to the clearance change in orthodontic treatment in-process, often need place the push spring in the disappearance tooth clearance, utilize the push force that push spring self deformation produced to control the size in the disappearance tooth clearance of reservation. When the missing tooth clearance is reduced, the push spring is extruded to generate a push force, so that the missing tooth clearance is enlarged; when the missing tooth space increases to reach a predetermined distance, the push spring restores the original length so that the pushing force is no longer generated. The operation of reserving the missing tooth space by the method is simple, but the size of the missing tooth space depends on the experience of an orthodontist to select the push spring with proper length, and the treatment result is lack of accuracy. Meanwhile, the reserved missing tooth space determines the size of the tooth for subsequent tooth filling restoration treatment, and if the size of the missing tooth space is not coordinated with the ideal tooth form in the restoration stage, an orthodontist is required to adjust the missing tooth space, so that the treatment process is repeated, and the treatment time is prolonged.

The patient with combined tooth loss and malocclusion corrects the malocclusion and aligns the dentition through orthodontic treatment, wherein gaps which cannot be closed still need to be restored to the missing teeth through a subsequent denture repair means, so that the reservation of reasonable gaps is one of important treatment targets. The traditional method has inaccurate control on the missing tooth space and can cause the situation that the missing tooth space needs to be readjusted in the later repair stage.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

The utility model provides an occupying body for maintaining missing tooth space in the orthodontic treatment process of a missing tooth patient, which is made of resin and comprises a tooth body 1, a positioning wing 2 and a bracket block 3 as shown in figure 1.

The shape and size of the tooth body 1 are the shape and size of a future ideal restoration of a missing tooth, namely the shape of a false tooth to be installed subsequently, the function of the tooth body is to occupy space in the missing tooth space, the requirement is to meet the standard morphological rule of the missing tooth position, and meanwhile, the shape proportion of adjacent teeth and opposite teeth with the same name needs to be referred and is consistent with the adjacent teeth and the opposite teeth, so that accurate reference value can be provided, and the optimal space distance of the reserved space is determined.

The positioning wing 2 is a resin wing plate connected with the crown of the tooth body 1 (i.e. the end far away from or back to the gum), can be attached to cover the jaw face or the cusp of the adjacent teeth at the two sides of the missing tooth (i.e. the missing tooth), has the function of covering the adjacent teeth by attaching, can place the tooth body 1 in the ideal missing interdental space, or is close to the adjacent teeth at one side, or is positioned in the middle of the missing interdental space, and the specific position is determined according to the needs of a case.

After the positioning wings 2 confirm the position of the tooth body 1, the bracket block 3 can be accurately fixed on the arch wire. The bracket block 3 is a resin block which is positioned in the center of the labial side of the tooth body 1 and protrudes outwards, simulates the shape of an orthodontic bracket, has the volume of about 2 x 2mm, and is used for being connected and fixed with an arch wire to fix the tooth body 1 in the position of a tooth row and play the role of occupying the tooth row. That is, the orthodontic practitioner can open a groove in the bracket block 3 and fix the bracket block to a orthodontic archwire by means of a resin bonding material, a metal ligature, or the like, so that the tooth body 1 can be stably fixed to the dentition. Once the bracket block 3 is firmly connected with the arch wire, the positioning wing 2 can be abraded, and the long-term occlusion relation of interference of the upper dentition and the lower dentition of the positioning wing 2 is avoided.

In the process of straightening the aligned dentition, an orthodontist can observe the gap between the tooth body 1 and the adjacent teeth and close the gap by moving the adjacent teeth. When the tooth is subsequently repaired, the lost tooth space occupied by the tooth body 1 is an ideal shape space of the repaired body, and the position of the tooth is not required to be adjusted during repair. The utility model discloses an occupy-place body is the resin material, can pile the preparation of moulding resin material by hand on patient's dentition gypsum model and accomplish, perhaps utilizes the oral cavity digital technology, and the design is accomplished in computer aided design auxiliary manufacturing (CADCAM) software, prints the preparation through 3D and generates to simplify the preparation degree of difficulty.
