Technical Field

The disclosure relates to the technical field of immediate restoration of a planted temporary restoration, in particular to a method, a device and a system for immediate restoration of a pre-formed temporary restoration.

Background

And (3) temporary prosthesis: after the implant is completed, under the condition of good initial stability, a clinician can use self-setting resin and other materials to complete the manufacture of a temporary prosthesis (crown-bridge) through operations such as manual shaping, trimming and the like, so that the purpose of immediate repair is realized, and the shaping box of the gum cuff can help prevent the gum from retracting.

Performing temporary restoration: before operation, a temporary restoration digital model meeting the functional and aesthetic requirements is designed in the restoration software in advance, and the temporary restoration is processed in a cutting mode. Because there are many uncontrollable and unpredictable deviations in the process of the implant operation, which finally causes the deviation between the implant site of the implant and the ideal implant site, in order to accommodate and correct the deviation, the existing pre-formed temporary prosthesis is usually designed to be shell-shaped, i.e. the interior is hollowed, and the semi-preformed temporary prosthesis is realized by enlarging the preset screw hole channel, so that the immediate repair can be completed through some necessary trimming in the clinical operation.

The clinical application methods of the existing preformed temporary prosthesis comprise two methods:

the first method comprises the following steps: the preformed temporary prosthesis is designed into a hollow shell crown or a hollow shell connected crown (called Temp shell) with wings, bonding is carried out in the mouth, the outline of the part, which penetrates out of the base, is trimmed by resin outside the mouth, the wings are removed, the appearance is polished smooth, and then the temporary prosthesis is worn back in the mouth of a patient.

And the second method comprises the following steps: the preformed temporary prosthesis is designed into a hollow shell crown or a hollow shell connecting crown without wings, the hollow shell crown or the hollow shell connecting crown is positioned and bonded in the mouth by an additional guide plate, the outline of the penetrating part of the abutment is trimmed and smoothed by resin outside the mouth, and the abutment is worn back in the mouth of a patient.

The problems that exist are that:

1. the bonding is required in the mouth, the polymerization of the resin generates heat, and the bonding in the mouth is easily infected.

2. The manual operation is still more, and the operation experience of doctors is higher.

3. The first method requires de-winging and trimming, and the second method requires an additional guide plate, which increases the cost.

The clinical application method of the existing preformed temporary prosthesis comprises the following steps: a half-mouth temporary prosthesis is designed in software in advance, a screw hole is enlarged, after the implantation is finished, a rubber dam is arranged, the half-mouth temporary prosthesis is arranged in the mouth in place, the bonding is carried out in the mouth, the appearance is trimmed outside the mouth, and then the half-mouth temporary prosthesis is worn back in the mouth of a patient.

The problems that exist are that:

1. the bonding needs to be done inside the mouth, the polymerization of the resin generates heat, and the bonding inside the mouth is easily infected.

2. Half-mouth implantation, the implant quantity is more, and the deviation of different angles and different axial directions can be generated, so that even if the channel of the screw hole is enlarged, the situation of difficult positioning can be frequently met, and a doctor needs to have enough experience to carry out the trimming operation beside the external chair.

3. If the planting scheme needs to be modified in the operation, the preformed prosthesis cannot be used.
