ABSTRACT:
BACKGROUND
The present invention relates generally to implant dentistry, and more particularly, to disposable implant kits, and a method of using the kits, unique to post-extraction implantation procedures for the various and different dental areas. In addition, the kit (s) can be utilized in other cranio-facial bone areas as well.
The process of fashioning a dental restoration for a patient usually involves several steps over a period of months. In a new method for placing an implant, typically after an extraction as shown and described in my copending application entitled METHOD AND APPARATUS FOR PERFORMING RIDGE PRESERVATION AND IMMEDIATE IMPLANT TREATMENT, filed

, an extraction socket in the alveolar bone of the patient is already opened to expose the bone. Rather than waiting months for this extraction socket to heal, it is possible to place an implant immediately after an extraction (before the bone has healed). A bore or extension hole is drilled at a base of the extraction socket 3 to 6 millimeters beyond the end of the socket (apically) to provide suitable space for insertion of a dental implant. The implant is then placed into the extraction socket using techniques and instrumentation appropriate to the type of implant being mounted. In most cases, a bone void will exist in the space between the upper portion of the implant and the exposed extraction socket. This bone void maybe “back filled” with bone graft material to promote integration (“osseointegration”) between the implant and the bone, either with or without a membrane barrier depending upon the graft material used. For a single stage implant procedure, an abutment is installed in the implant during initial installation in the extraction socket. In a two stage procedure, the implant is submerged into the bone, and a healing cap or other structure is threaded into the top of the implant to prevent the migration of bone or soft tissue into the implant abutment space. New bone, however, may grow around and over the implant. If bone covers a submerged implant, it must be removed by a burr prior to installation of an abutment. A transfer coping is placed over the abutment to transfer an impression to resilient impression material from which a model is made of a previous edentulous site where the implant was installed. The artificial tooth is then mounted over the abutment structure in accordance with well known methods.
SUMMARY OF THE INVENTION
In accordance with the above objects and additional objects that will become apparent hereinafter, the present invention provides a disposable kit for implementing immediate post-extraction dental implantation. The kit includes a dental implant of a specified size for a particular dental area of the mouth; a transfer coping attachable to the dental implant for creating an immediate impression for making a model to produce a prosthetic tooth; bone graft material for filling the void around a portion of the implant after implantation; and a portable housing having a plurality of compartments for storing the dental implant, the transfer coping, and the bone graft material, etc. A wound dressing may also be stored in one of the compartments if desired (e.g., Biofoil®). The kit housing may include indicia corresponding to the target dental area.
The present invention also provides a kit system comprising a plurality of disposable kits, each kit being adapted for immediate post-extraction dental implantation on a particular dental area. Each kit includes a dental implant of a specified size for a particular dental area; a transfer coping attachable to the dental implant for creating an impression for making a model to produce a prosthetic tooth; a bone graft material for filling the void around a portion of the implant after implantation (where in some instances it may be necessary, because of a narrow or thin buccal or lingual plate housing the newly placed implant, to build out or expand the bucco-lingual diameter to thereby increase the amount of bone holding the implant under function); and a portable housing for storing the dental implant, the transfer coping, the bone graft material and the wound dressing, etc.
The kit system may include anon-disposable instrument kit including a plurality of reusable and sterilizable tools such as insertion instruments, a scissor, and a suture holder, etc., for implementing immediate post-extraction dental implantation, and a housing for storing the instruments.
The invention further provides a method for immediate post-extraction implantation of dental implants, comprising the steps of: immediately after extraction, removing from a kit adapted for a particular dental area of the mouth, a dental implant of specified dimensions for the particular dental area of the mouth, and inserting the dental implant into an extraction socket; removing a transfer coping from the kit, and attaching the transfer coping to the dental implant to make a model to produce a prosthetic tooth. The method may further comprise the step of removing a bone graft material from the kit and filling a void area around a portion of the implant after implantation.
