DENTAL IMPLANT DEVICE, SYSTEM AND METHOD OF USE

FIELD OF THE INVENTION

The present invention relates to a dental implant device and a method for using the same and in particular, to such a device and method in which the implant device projects the implant anchor's location, orientation and axis while facilitating the treatment of the peri-implant tissues.

BACKGROUND OF THE INVENTION

Dental implants are well known in the art and typically include a dental implant anchor securely inserted into the patient's jawbone, an abutment member attached to the dental anchor, and a prosthodontic restoration coupled thereon.

The method of implantation generally occurs over various stages where that generally initiates with the implant anchor's introduction into the jawbone and ends with loading the implant anchor with an abutment and restoration. There are a number of intermediates steps and procedures that are undertaken between the implant anchor's introduction and loading that can be spread over a three to nine month period.

The intermediate steps generally involve allowing the host tissue, gingiva and peri-implant tissues to heal and to be modeled in preparation for receiving the abutment and restoration. These intermediates steps are lengthy and require about eight individual medical procedures and/or iterations with a professional caregiver, where following each procedure and/or iteration requires a healing period.

Each intermediate steps requires different implant devices to facilitate the tissue healing and modeling process, for example cover screws, healing abutments, impression copings.

SUMMARY OF THE INVENTION

State of the art dental implant devices utilized during the intermediate steps of the implant procedure require multiple invasive and costly procedures.

Following the implantation of a dental implant anchor, the anchor is not easily discoverable following the healing period. This is due to that fact that during the healing process, the morphology of the gingival tissue covering the anchor is restored, making it difficult to locate and/or discover the underlying anchor. The exact location of the anchor is not known, nor readily visible to the practitioner. The approximate implant anchor site is estimated and thereafter located by way of surgical exploratory probing, often utilizing inaccurate surgical incisions.

During the anchor uncovering process much of the host tissue is needlessly lost. Such tissue loss can lead to various medical drawbacks for example, vertical bone loss, prolonged re-healing period, formation of closed and inaccessible voids, pockets, cysts, formation of fibrotic tissue, improper sealing possibly leading to contamination, overlapping of the anchor's margins with proliferated neo-tissue leading to inadequate abutment coupling and loosening.

Once the implant anchor is discovered the host tissue must be prepared for implant loading with various devices such as a healing abutment, to allow the peri- implant tissue to be modeled in preparation for implant anchor loading.

The dental implant device, system and method of use according to embodiments of the present invention provide for a non-invasive and a-traumatic method that remotely treats the peri-implant tissue to promote faster healing, while significantly reducing the number of procedures and care-giver iterations required between anchor implantation and loading. The dental implant device of the present invention further facilitates the implantation process by providing for readily identifying the location, orientation and axis of the implanted dental implant anchor in a non-invasive manner, for example by visual inspection. The dental implant device according to embodiments of the present invention further provides for minimizing peri-implant host tissue loss during the process of discovering and uncovering of the implant anchor, which takes place prior to implant loading.

Optionally and preferably the device according embodiments of the present invention provides for projecting the anchor's axis relative to surrounding structures for example including but not limited to anatomical structures, the opposing jaw, the same jaw, adjacent teeth or prosthodontic elements, morphological elements, or any combination thereof.

Impression coping and /or the transfer process is facilitated by device 410 in that exposure of the implant anchor 32 is not required to carry out the impression and transfer process, as is currently implemented in the art. Device 410 provides for maintaining implantation site without exposing anchor 32 by utilizing proximal portion 412 to remotely indicate the position, orientation and axis of anchor 32 and connection platform aperture 38. Most preferably reference markings 412n, 420m, 412r and/or external surface 412s are correlated to the shape and orientation of connection platform aperture 38 therein facilitating the transfer and impression processes by projection the configuration of aperture 38 on proximal portion 412 making it readily available.

Next in stage 707, following the healing process and impression of the implantation site, prior to the uncovering of the implant anchor 32 as depicted in stage 708, the peri-implant tissue may be remotely and a-traumatically anesthetized by delivering anesthesia via channel 420, 422, to the peri-implant tissue via exit pores 420e, for example as shown in FIG. 6E. FIG. 6E shows a syringe comprising anesthetics delivered to the peri-implant tissue, as shown by directional arrow, through proximal end 420p of channel 420.

Next in stage 708 the implant anchor 32 is uncovered by removing the gingival tissue above the anchor. Most preferably, device 410 provides for removing minimal tissue by providing tissue removal device 500 with a guide utilizing proximal portion 412, 518 to guide device 500 toward anchor 32, for example as shown in FIG. 6E. Exposer 500 provides for exposing the anchor directly in a minimally invasive manner that does not require poking and prodding as the implantation site is readily viewable due to the projection provided by proximal portion 412 of cover-screw 410. Most preferably minimal gingival tissue covering anchor 32 is excised with exposing surface 512s, FIG. 5A-B, to reveal anchor 32 and cover-screw 410, as they are received into proximal end lumen 516. Most preferably this further provides for saving gingival tissue while exposing the anchor both in its location and implantation axis.

Next in stage 709 the implant loading process is undertaken as is known in the art. Optionally and preferably device 410 is disassociated from anchor 32 allowing abutment loading as is known in the art.

Optionally device 410 comprising proximal end threading 412t may be retained and associated with anchor 32 to allow for an abutment assembly, an over denture attachment or additional prosthetic elements, may be built, coupled or otherwise associated directly onto cover-screw 410 about its proximal end 412 optionally utilizing extension member 12e, for example as shown in FIG. 6F. Optionally an abutment assembly may be built on proximal portion threading 412t and/or extension member 12e, for example as described in co-owned PCT Application No. PCT/IB2012/053829, incorporated herein by reference as if fully set forth.

Optionally exposer 500 may be utilized to facilitate abutment assembly buildup about proximal end 412. Optionally, distal end opening 516d and central lumen 516 may be utilized to facilitate introducing an optional extension member 12e to facilitate the initiating an abutment buildup about anchor 32, for example as shown in FIG. 6E-F.
