  • Retainer combination of a packaging and a retainer, adapter and a retainer with a support structure for a surgical device
  • the present invention relates to a retainer for holding at least a first surgical device and a second surgical device, and to a combina- tion of a packaging for a retainer and a retainer according to the preamble of the independent claims Further, the present invention re- lates to an adapter for a surgical device and a retainer comprising a support structure.
  • teeth may be artificially replaced by a dental implant, an abutment and a crown.
  • a dental implant In an implantation procedure first a jaw bone is accessed by incising an overlying gingival tissue. Then a position for the implant is identified. Into this position a drill drills a hole into the jaw bone. The dental implant is then implanted into this hole. After the implantation a dentist inserts a healing screw or a healing abutment into the dental implant and may close the surgical site for healing. At a later stage the site is reopened in a second operation and the healing screw is exchanged with an abutment. Lastly, a crown is placed onto the abutment to complete the operation. In some instances all steps may be executed in a single operation.
  • the coupling of the dental implant to the bone requires a suitable surface for osseointegration with the implant.
  • the implant is a medical device. It needs to be transported sterilely in a retainer. The retainer holds and protects the dental implant whilst the implant is transported and handled. During the implantation procedure the implant needs to be removed from the retainer. The implantation procedure may be facilitated by using an adapter which connects the dental implant to an insertion device.
  • US 8,973,747 B2 provides a package for a dental implant which compris es a housing with a compartment that can be closed by way of a perfo- rable or slidable cover.
  • the compartment is essentially liquid tight.
  • the package includes an opening for a healing cap.
  • the procedure of removing the dental implant and the healing cap is not based on the needs of a surgeon or a surgical procedure. Hence the handling is complex. Further for liquid tightness expensive high precision fabrication techniques are required.
  • US 9,119,688 B2 discloses a holding device for retaining and transporting a dental implant.
  • the holding device comprises an engagement section for engaging a manipulating section, a retention section for retention on a packaging and a securing section for connection to a dental implant.
  • the retention section includes annular shoulders and a circumferential groove defined by the annular shoulders. This groove functions to receive a mating structure such as a flange of an external package to allow a dental implant to be positioned within the package.

  • US 8,292,075 B2 discloses a housing for accommodating a dental implant.
  • the housing comprises a first body portion and a second body portion. In between those portions an inner space is defined.
  • the second body portion is capable of rotating with respect to the first body portion along a pivot axis to expose an open end. This open end accommodates the dental implant.
  • the device does not support a second surgical device such as a healing screw which is also needed during the implantation procedure.
  • the housing forms an airtight space which increases fabrication costs.
  • the object of the present invention is to overcome disadvantages of the prior art.
  • the object of the invention is to provide an easy to use retainer which supports a surgeon during the procedure.

  • the first surgical device may be a dental implant.
  • a dental implant is understood as a surgical component adapted to provide an interface with a bone of the jaw to support a dental prosthesis such as a crown, a bridge, or hybrid dentures.
  • the first surgical device may be a dental implant directly attached to the retainer.
  • the first surgical device may also be a combination of a dental implant with an adapter wherein the adapter is directly connected to the retainer and holds the first surgical device.
  • the retainer may be made from a polymer, such as a polycarbonate, PET or PBT or any other suitable material.
  • pivotable relative to each other refers to at least one of the body parts having a pivoting motion.

  • a second surgical device may be a healing screw which prevents ingrowth of tissue, in particular gingival tissue, into the implant.
  • the first position is a position preferably used for handling and transport because both surgical devices are firmly attached to the retainer .
  • the retainer may be brought into the second position and the first surgical device becomes removable. At this stage, only the first surgical device is needed. Thus, during removal of the first surgical device, the second surgical device should not be removable. If, at a later stage, the retainer is pivoted to the third position, the second surgical device can be removed from the retainer.
  • the retainer provides a holding structure for a second surgical device.
  • Another advantage is an easy and convenient mechanism of removal by a pivoting motion.
  • the retainer is adapted to the surgery procedure, i.e. the removal of devices is based on a surgical procedure as normally conducted. During the procedure first a first surgical device is needed and later the second surgical device. Surgical devices not yet needed may thus not be lost and remain fixed.
  • the retainer includes a limiting portion which prevents movement to the third position. The limiting portion is preferably adapted to be unlocked by removing the first surgical device .
  • the second surgical device cannot be removed unintendedly . Only after the limiting portion is unlocked, the second surgical device may be removed. In the preferred embodiment the first surgical device must be removed before the second surgical device. Thus, a sec- ond surgical device cannot be lost during surgery before needed.
  • the limiting portion is particularly preferred a portion of the second body part.
  • the limiting portion may be designed such that the first surgical device limits the pivoting movement. In this case the first surgical device acts as a stopper.
  • the retainer comprises a pivot axis which extends substantially perpendicular to a longitudinal direction of the first and second body parts.

  • the first surgical device is an adapter and a dental implant, wherein the adapter is preferably directly anchored to the retainer.
  • the adapter allows the use of a single insertion device for all sizes of dental implants. Hence, the retainer and its first support structure do not need to be adjusted for each individual dental implant size .
  • the dental im- plant is only indirectly anchored to the retainer and requires no at- tachment structures for connection to the retainer. Further, an outer surface of a dental implant is not in direct contact with the retainer, and hence not damaged or polluted by the retainer. Also no struc- tures or features are necessary for a direct connection to the retain- er. Furthermore, a variety of materials may be used for the retainer which are otherwise unavailable due to the sensitive osseointegration surfaces of the implant.

  • Figure 5 shows a removal of a healing screw 4 with a screw driver 20. If the first body part 5 and a second body part 6 are in the third po- sition (see also Fig. 2) then the healing screw 4 can be attached to a screw driver 20 and the healing screw 4 can be removed from the retainer 1. This position can only be reached if the adapter was previously removed. After removal of the adapter 3 and implant 2, the retainer is pivoted by pressing grips 22 to a third limiting stop. The first and second body part may not pivot past the third limiting stop. The third limiting stop is defined by a second limiting portion 28 of the second body part 6 being in contact with the first body part 5. The third limiting stop also defines the position in which the healing screw 4 is removable from the retainer 1.

  • the ledges 18 fix the adapter on the shape 17.
  • the support structure includes a gap 19. The distance between the ledges 18 is shorter than a diameter of the adapter 3. Hence, the ledges have to be pushed outwardly when the adapter is inserted.
  • the gap 19 provides the first support structure 8 with the necessary flexibility.
  • adapter locking means 11 are slid such as to close the insertion opening 25.
  • the adapter 3 may not be removed then because adapter locking means 11 consisting of a short bar close the insertion opening 25.
  • the packaging 100 includes two parts: a transparent blister (shown) and a removable cover (not shown) .
  • the blister has a recess 101.
  • the packaging 100 includes two features which prohibit a pivoting motion of the retainer 1.
  • First the recess 101 is formed such that it includes contact areas 103 on the inner surface of the wall of the recess 101.
  • the contact areas 103 prohibit the motion, in which the ends 36 of the retainer depart from each other.
  • the opposite motion is prohibited by the first limiting stop 10 (see Fig. 1.
  • the recess 101 includes a bulge 106.
  • the bulge 106 extends between ends 35 and thus the ends 35 may not be moved towards each other by pressing the grips 23.
  • the removable cover When a user desires to remove the retainer 1 from packaging 100, first the removable cover needs to be removed.
  • the removable cover is a peel-off seal.
  • the peel-off grips 108 provide an easy access to the peel-off seal. Afterwards a user may choose either of two options to remove the retainer 1 from the recess 101.
  • the user utilizes an area for withdrawal 105.
  • the user holds the retainer on the grip 23 of the second body part 6 on both sides of the wall forming the grip.
  • the recess includes an indentation 110 on the grip 23 of the first body part 5. This indentation 110 prevents a user from using both grips 23 to remove the retainer 1 from the recess. This would be undesired since it could trigger a pivoting motion and thus a release of adapter 3 and implant 2.
  • FIG. 11 shows a schematic view of the adapter 3 in a perspective view.
  • the adapter 3 is intended to connect the implant 2 to the insertion device 32.
  • the adapter 3 comprises three sections: a surgical section 203, an engagement section 204 and a support section 205.
  • the surgical section 203 is sized according to the size of the according implant 2.
  • the engagement section 204 on the other hand is standardized to a single size such that a dentist only needs one insertion device 32 with one size for all sizes of implants.
  • the surgical section 203 engages the implant 2 and is located on the side of a first end 201 of the adapter 3.
  • the surgical section 203 comprises force transmission means 206. These force transmission means transfer a torque around a longitudinal axis 219 from the adapter 3 to the dental implant 2.
  • the force transmission mean 206 shown in fig. 11 is a spline shaft 212.
  • Lobes 214 extend from a circular base.
  • the force transmission means 206 are inserted into a spline hub of the dental implant 2.
  • the spline hub is adapted in size to receive the spline shaft 212.
  • the surgical section 203 further comprises attachment elements 207.
  • the attachment elements 207 provide a retention force along the longitudinal axis 219 between implant 2 and adapter 3. Hence, the adapter is securely fixed in the implant 2.
  • the attachment elements 207 are spring elements 209.
  • the three spring elements 209 seen in Fig. 11 are basically longitudinal bars which extend from the first end 201. These bars may be deflected in a radially inward direction. The resistance to such reflection provides a frictional retention force which prevents an unintended removal of the adapter 3 from the implant 2. Also the retention force enables handling the implant with the adapter. Thus, damage or contamination of the implant can be avoided.
  • the spring elements 209 include each one contact sec- tions 210 pointing in a radially outward direction. As can be seen from Fig. 12, the spring elements 209 engage an inner threading 217 of the implant 2. Ideally the retention force is high enough to allow a stable fixation of the implant 2 and low enough to allow a comfortable removal of the adapter 3 from the implant 2 with- out any further tools.
  • the retention force of the spring elements may be too high for a comfortable removal with a single larger contact section.
  • two contact sections instead of one could be provided which are spaced apart according to a pitch of the inner treading 217.
  • the deflection of the spring elements is reduced and a removal is facilitated while the fixation remains stable.
  • the support section 205 is de- scribed.
  • the support section comprises two shoulders 218.
  • a recess 208 is located in between the two shoulders 218.
  • the adapter 3 has a hexagonal shape 216.
  • a cross section (A-A) of the hexagonal shape 216 shows six flat surfaces 219 (see Fig. 13) . As shown in Fig. 13 the flat surfaces are connected via round edges 220.
  • the engagement section 204 comprises an opening 221 on the second end 202.
  • a cross-section of this opening is adapted to receive the insertion device 32.
  • the cross-section of the opening 221 is a spline hub 215.
  • the insertion device 32 includes a spline shaft with a corresponding cross-section 224. In between lobes 226 there are depressions 225.
  • the depressions 225 may be connected to a shaft of the insertion 32 device with a conical section 223.
  • the conical section 223 allows a releasable attachment between insertion device 32 and adapter 3.
  • the insertion device 32 further includes orientation notches 222.
  • the orientation notches 222 are arranged at the circumferential position of the depressions 225.
  • the adapter 3 also includes elon- gated notches 213. In order to bring the spline hub of the adapter and the spline shaft of the insertion device 32 in connection, the notches 222 and 213 are aligned. Then the spline shaft can be directly insert- ed into the spline hub without user having to find a correct orientation by try and error.
  • FIG 11 shows a pre-defined breaking point 211 in between support section 205 and engagement section 204.
  • the insertion device 32 transmits a torque to the adapter 3.
  • the adapter transmits this torque via the force transmission means 206 to the implant 2.
  • the implant 2 is thereby screwed into a bone of the jaw.
  • the implant may be inserted into hard cortical bone and thus a high torque may have to be transmitted from the adapter to the implant. However, excessive torque may damage the implant. In order to prohibit such a case the pre-defined breaking point breaks. Thus the transfer of said excessive torque is prevented. .
