[0002] Dental veneers are a type of teeth whitening and restoration technology. Dental veneer restoration is to stick a layer of veneer with a material similar to normal tooth color on the surface of stained teeth to cover the color of the teeth. At present, this technology has been widely used in stomatology and is very popular among consumers.

[0003] For example, the Chinese utility model patent with publication number CN211381866U discloses a "front teeth veneer bonding guide plate" with a positioning clip. When in use, the veneer to be fixed, which has been coated with glue, is placed on the corresponding positioning clip, and then the guide plate and the veneer on it are fixed to the tooth to be repaired. Since the positioning clip is formed by 3D printing and can position the veneer to a fully seated state, it can ensure that the veneer is exactly in place, and the gap reserved between adjacent positioning clips is just convenient for medical staff to remove the overflowed glue, and the connecting strip at the bottom of the positioning clip ensures that multiple veneers can be pasted simultaneously, and avoids slight misalignment of adjacent veneers that may cause individual veneers to fail to be effectively positioned.

[0004] The connecting strip on the lip side of this patent does not fit the tooth root, making it inconvenient to observe whether the veneer is in place. The connecting strip is far away from the tooth, which is not conducive to the overflow and cleaning of the adhesive. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 5 As shown, a guide plate for pasting veneers in place in an aesthetic area includes a plurality of positioning clips 1 and a connecting strip 2 for clamping the veneers and the teeth to be repaired, and a positioning clip 1 is arranged on the top of the connecting strip 2.

[0027] The connecting strip 2 and the positioning clip 1 are integrally formed by 3D one-piece molding. The positioning clip 1 includes a front panel 11, a top panel 12, and an inner panel 13. The front panel 11 is used to fit the front surface of the veneer; the top panel 12 is used to fit the top of the teeth; and the inner panel 13 is used to fit the inner surface of the teeth. The front panel 11, the top panel 12, and the inner panel 13 are connected in sequence, and the bottom of the front panel 11 and the bottom of the inner panel 13 are both connected to the connecting strip 2.

[0028] The connecting strip 2 includes a labial connecting strip 21 and a lingual connecting strip 22. The labial connecting strip 21 is arranged at the bottom of the front panel 11, and the lingual connecting strip 22 is arranged at the bottom of the inner panel 13. The labial connecting strip 21 is arranged at the root of the teeth on the labial side, which is consistent with the shape of the patient's tooth roots. Specifically, the labial connecting strip 21 is provided with a plurality of protrusions 23 at intervals, and the protrusions 23 can fit between the roots of the teeth on both sides fixed by the positioning clamp 1 and fit with the tooth roots. The protrusions 23 provided on the labial connecting strip 21 can make it easier to observe whether the veneer is in place, and at the same time can prevent the adhesive for fixing the veneer from overflowing along the bottom of the tooth root, which is convenient for cleaning the adhesive. The lingual connecting strip 22 is provided at a position slightly lower than the root of the teeth on the lingual side.

[0029] A plurality of positioning clips 1 are arranged on the connecting strip 2, and a single positioning clip 1 does not completely cover a single tooth of the patient, so a processing window 3 is formed between the positioning clips 1. The processing window 3 can facilitate medical staff to remove the overflowed glue, and at the same time, it is convenient to observe the pasting condition of the veneer and adjust the veneer.

[0030] The positioning clips 1 on the left and right sides are provided with in-place cross-section observation windows 4, which are arranged in the middle of the top panel 12 and fit the edge of the positioning clip 1. The in-place cross-section observation windows 4 can determine that the position of the positioning clip 1 is fixed without deviation.

[0031] When making the veneer-in-place bonding guide plate for the aesthetic area, it is necessary to use an oral scanner to obtain the soft and hard tissue data of the patient's mouth, design the veneer on the digital software according to the acquired intraoral data, and combine the completed veneer data with the intraoral data to output the digital model data. In this embodiment, pladstycad software is used to design the veneer-in-place bonding guide plate on the combined digital model. The veneer-in-place bonding guide plate is integrally formed using 3D printing.

[0032] When in use, the veneer coated with glue is installed on the positioning clip 1, and then the aesthetic area veneer is fixed on the tooth to be repaired by pasting the guide plate in place. Since the guide plate model is designed specifically and formed in one piece by 3D printing, the veneer can be positioned to the tooth to be installed. The medical staff only needs to make minor adjustments and remove the overflowed glue from the processing window 3. A plurality of positioning clips 1 are provided on the connecting strip 2, and the positioning clips 1 can fix the veneer, so that multiple veneers can be pasted simultaneously, and the slight misalignment of adjacent veneers can be avoided, which may cause some of the veneers to fail to be effectively positioned.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
