[0036] The outer sleeve crown base 201 is vertically provided with a countersunk hole 205 connected with the groove 204, and the angle α between the central axis of the countersunk hole 205 in the outer sleeve crown base 201 and the central axis of the outer sleeve crown base 201 is 0°, that is, the central axis of the countersunk hole 205 in the outer sleeve crown base 201 coincides with the central axis of the outer sleeve crown base 201, that is, the outer sleeve crown base 201 is vertically arranged on the mounting portion 101, and a mounting screw 203 is arranged in the countersunk hole 205, and the outer sleeve crown base 201 is fastened to the mounting portion 101 through the mounting screw 203, and the outer sleeve 202 cooperates with the outer sleeve crown base 201, and the outer sleeve 202 is sleeved on the outside of the outer sleeve crown base 201. The mounting screw 203 can further improve the firmness of the outer sleeve crown base 201 and the mounting portion 101.

[0037] The mounting portion 101 is truncated cone-shaped, with a mounting hole 106 provided at the central axis of the mounting portion 101, and the mounting hole 106 is a blind hole, and an inner side wall of the mounting hole 106 is provided with an internal thread, and the mounting screw 203 passes through the countersunk hole 205 and is installed in the mounting hole 106, so that the outer sleeve crown abutment 201 is more firmly combined with the mounting portion 101, thereby extending the service life of the restoration abutment with a sleeve crown abutment provided in the embodiment of the present invention.

Through the above arrangement, the processing of the connection parts is convenient, and the production efficiency is greatly improved.

[0040] Example 2

[0041] like Figures 3 to 5As shown, a restoration abutment with a telescopic crown abutment provided by Example 2 of the present invention is different from Example 1 in that the connection portion includes a first connection portion 102 and a second connection portion 103, the first connection portion 102 is arranged at the upper end of the second connection portion 103, and a through hole 107 is arranged in the first connection portion 102, and a threaded hole 108 is arranged in the second connection portion 103, the through hole 107 is connected to the threaded hole 108, the central axis of the through hole 107 coincides with the central axis of the threaded hole 108, and the angle β between the central axis of the threaded hole 108 and the central axis of the mounting portion 101 is 15°. A connection bolt 109 is also included, the connection bolt 109 passes through the through hole 107 and the threaded hole 108 in sequence and extends outward, and the threaded portion is a screw portion 1091 of the connection bolt 109 located outside the threaded hole 108. Through the above arrangement, the connection part in the multi-element base 100 is tilted at an angle of 15° and fixedly arranged through the mounting part 101 and the telescopic crown base 200, which facilitates the restoration of the denture, thereby reducing the clinical operation time, achieving the purpose of improving work efficiency, and greatly facilitating maintenance.

[0042] Example 3

[0043] like Figures 6 to 8 As shown, a restoration abutment with a telescopic crown abutment provided by Example 3 of the present invention is different from Example 2 in that the angle β between the central axis of the threaded hole 108 in the second connecting portion 103 and the central axis of the mounting portion 101 is 30°. Through the above arrangement, the connection portion in the multi-element abutment 100 is tilted at an angle of 30° and fixedly arranged through the mounting portion 101 and the telescopic crown abutment 200, which facilitates the restoration of the denture, thereby reducing the clinical operation time, achieving the purpose of improving work efficiency, and greatly facilitating maintenance.

[0044] Example 4

[0045] like Figures 9 to 11As shown, a restoration abutment with a telescopic crown abutment provided in Example 4 of the present invention is different from Example 1 in that the angle α between the central axis of the countersunk hole 205 in the outer sleeve crown abutment 201 and the central axis of the outer sleeve crown abutment 201 is 7.5°. Through the above arrangement, the outer sleeve crown abutment 201 is installed on the mounting portion 101 through the groove 204 at an angle of 7.5° to the right, and the outer sleeve 202 is also installed on the outer sleeve crown abutment 201 at an angle of 7.5° to the right, that is, the telescopic crown abutment 200 and the multi-element abutment 100 are set at 7.5°; in addition, the angle α between the central axis of the countersunk hole 205 in the outer sleeve crown abutment 201 and the central axis of the outer sleeve crown abutment 201 can also be selected as 15°, 22.5° or 30°. Through the above arrangement, the restoration of the denture is convenient, thereby reducing the clinical operation time, achieving the purpose of improving work efficiency, and greatly facilitating maintenance.

[0046] The restoration abutment with a telescopic crown abutment provided by the embodiment of the present invention uses a telescopic crown abutment on a multi-abutment, and the outer sleeve crown abutment in the telescopic crown abutment can be set to an inclination angle of 0°, 7.5°, 15°, 22.5° and 30° to match the finished sleeve (i.e., the outer sleeve); at the same time, the multi-abutment can also be set to an inclination angle of 0°, 15° and 30° to match the telescopic crown abutment, so as to meet the multi-angle restoration required in the process of denture restoration, reduce the operation time of clinical denture restoration, and facilitate the later maintenance of dentures. At the same time, the advantages of the multi-abutment screw retention and the syncone abutment are combined, and the purpose of designing a multi-angle abutment is to find a common positioning path between multiple abutments. Multiple implants are connected as one, and no screws or adhesives are required for retention. They can be retained only by the friction between the sleeve and the abutment, which greatly facilitates disassembly and installation.

[0047] The restoration abutment with a sleeve crown abutment provided by the embodiment of the present invention can solve the problem of parallel positioning of multiple implants not exceeding 120° by using a multi-element abutment and a sleeve crown abutment in combination, especially when multiple implants in the maxilla are implanted at an angle. When there is an angle deviation of 120° between two implants, two 30° multi-element abutments can be used to solve the 60° angle deviation. When two 30° sleeve crown abutments are used, the 60° deviation can be solved again, so that even two implants with very different angles can be made parallel to each other, and the restoration can be completed using the sleeve crown abutment.

[0048] If the two implants have a 115° deviation, the above abutment can also be used, because the telescopic crown abutment itself has a taper of 4 to 6°, and the taper on both sides can reach 8 to 12°, so the restoration can be in place.

[0049] The restoration abutment with a telescopic crown abutment provided in the embodiment of the present invention is used for full-mouth implantation in the maxilla, especially trans-pterygoid implantation and trans-zygomatic implantation. In order to make the best use of the existing bone volume, the inclination angles of the implants are different, and sometimes the angles are even greater than 45°. The common positioning path can be roughly found by using a multi-abutment, and then the telescopic crown abutment can be used to accurately balance each implant. In this way, temporary dentures and final restoration dentures can be made by the restoration method of the telescopic crown.

[0050] The restoration abutment with a telescopic crown abutment provided in the embodiment of the present invention can solve the problem of arbitrary deviation of 0 to 120° between two implants in complex oral implant restorations, and can basically solve the problem of deviation of all implants, using efficient telescopic crown restoration.

[0051] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
