Description

Structure for eliminating dental implant restoration torsion difference and positioning restoration base station

Technical Field

The utility model belongs to the field of digital restoration and personalized restoration of dental implants, and particularly relates to a structure for eliminating a dental implant restoration torque difference and positioning a restoration base.

Background

At present, the prosthetic bases connected with the dental implant through the central fixing screw are divided into two types, one type is a prosthetic base with taper, and the other type is a non-taper step fixed prosthetic base. The repair base with the taper brings different distance heights (namely the distance between the top end of the repair base and the tail end of the implant) due to the taper of the repair base in the process of screwing the central fixing screw; the reason for this is that the greater the torque to the central set screw, the tighter the connection of the prosthetic abutment to the implant and the lower the distance height. Whether using a transfer rod for open mold extraction or a stamp cap for closed mold extraction, uncertainty in distance height occurs in the conventional mold extraction process of the implant; even in the digital mode taking process, errors due to torque differences occur when scanning the scanning rod (or scanning the multifunctional base station) by using the intraoral scanner. If the traditional repairing method is used, the next process can be carried out without finishing the previous process, so that the whole subsequent repairing process chain is waited, and the method is low in efficiency, high in energy consumption and resource-wasting. In the digital planting and mold taking process, the distance height is uncertain (the torque is small when the torque is large and the torque is small when the torque is large) because different force torsion is used for the central fixing screw, so that a technician can meet the inconformity of the coordinates of a substitute (a fitting for replacing an implant) in the model and an actual implant in a patient mouth in the process of printing a 3D model, and finally, the single tooth of the planting is repeatedly reworked, repeatedly modified and even manufactured again, one planting and repairing task is completed simultaneously by each process flow assembly line, and a great amount of time of doctors, patients and technicians is consumed, so that materials and medical resources are wasted. For the fixed restoration base station of non-tapering step, although solved the problem that leads to the difference of distance height because of torsion is poor, only fixed a position has been carried out in the upper and lower direction between restoration base station and the planting body, and the left and right direction has not realized the location about, leads to people when eating things, and restoration base station still can take place the drunkenness.

For the problem that the torque difference of the central fixing screw 2 inside the upper repairing abutment 3 of the implant 1 which is not yet repaired and the contact surface of the adjacent teeth do not have a fixed value because of different torque differences when a technician makes the repairing abutment 3 in the background, namely, the torque of the central fixing screw 2 is larger, the smaller the distance height D is, the larger the distance height D is, as shown in fig. 3, the utility model provides a structure for eliminating the dental implant repairing torque difference and positioning the repairing abutment, which is specifically as follows:

as shown in fig. 1 to 3, a contact portion is provided on the outer surface of the prosthetic base 3, the contact portion abuts against the end face of the inlet end of the implant 1, a tapered friction portion A5 is provided on the outer surface of the prosthetic base 3 located inside the implant 1, the friction portion A5 is located below the contact portion, a portion of the inner surface of the implant 1 corresponding to the friction portion A5 is a tapered friction portion B6, the friction portion A5 abuts against the friction portion B6, and friction force is generated by mutual friction in the process of generating torsion by the central fixing screw 2.

The contact part of the embodiment is a fixed step 4, and the fixed step 4 has a mouth structure, that is, the contact surface between the fixed step 4 and the end face of the inlet end of the implant 1 is a plane. The fixing step 4 in this embodiment is formed by shrinking the outer surface of the repairing base 3 inwards, and the top of the friction part A5 intersects with the inner edge of the fixing step 4.

The taper of the friction portion A5 of the present embodiment is the same as that of the friction portion B6.
