Definitions

  • the present invention relates to the field of dentistry. More particularly, the invention relates to dental restoration systems.
  • denture i.e. a dental restoration system
  • Conventional dentures rest on implants which are implanted in the gingival tissue of the ridge of the mouth. These dentures, where possible, may also be anchored to existing natural teeth. In cases where all of the teeth have been extracted from either the upper or lower jaw, or both, a full denture can be utilized.
  • a prosthetic tooth which connects to an abutment on a dental implant. After a dental implant is implanted, in the gingival tissue of the ridge, a construction, e.g. an abutment, is attached on top of the implant.
  • the abutment is a metal cylinder that the prosthetic tooth is built onto.
  • On the abutment a prosthetic tooth is fastened and it should look, and function, just like any other tooth in the mouth.
  • a patient with a multiple implant restoration goes through the same process and the final prosthetic teeth can vary between multiple single teeth or several teeth connected by a bridge or even a partial fixed denture, based on the planning of the dentist and the needs of the patient.
  • Another type of denture used today utilizes a construction such as an overdenture bar.
  • This dental reconstruction system comprises a conventional acrylic overdenture retained by suitable attachments, such as clips, to an implant supported cast bar otherwise known as an overdenture bar, e.g. a Dolder bar.
  • the overdenture bar is attached to the implants, in the patient's ridge, using designated screws.
  • the dentist is required to take an impression of the ridge, with the attached construction(s).
  • the impression is taken by filling a standard form with a solidifying substance such as polyvinylsiloxane and pressing it inside the mouth of the patient. Once this is completed the dentist will send the impression out to the laboratory for building a model of the mouth.
  • a solidifying material such as plaster of Paris, is then poured into the impression for creating the model. The model is then separated from the impression.
  • the model sculpts the patient's alveolar, ridge, implants and the construction.
  • the model since the model is used to create a prosthetic for a patient, the model has to be accurate enough in order to provide that the created prosthetic has a precise fit to the ridge of the patient. An inaccurate prosthetic can cause subsequent inconvenience, or even injuries, to the patient. Finally, the created prosthetic is seated in the mouth of the patient. However, this kind of procedure is time consuming, problematic, and may create inconveniences to the patient.
  • US 6,488,501 discloses a transfer jig for implant, in a dental surgery, which uses a tubular post and a tubular coping which is attachable and detachable from the post by a snap-fit attachment.
  • the described post has a hexagonal portion for location in a hexagonal socket in an implant and a frusto-conical portion which is a seat for the coping.
  • the coping has a diametrically opposed pair of slots in its end that seats on the post to receive a diametrically opposed pair of pins with a snap-fit, the pins being mounted on the post so that the coping is precisely located relative to the hexagonal portions.
  • the coping also has apertures formed through its tubular wall through which dental impression material is forced to form structural links when a dental impression is taken. Nevertheless, the described mechanism is complicated and requires a number of specially-designed tight-fitting parts for applying the described method.
  • the present invention relates to a method for attaching and detaching a construction to an implant in a ridge of a mouth comprising the steps of: (a) inserting at least one flexible holding device into said construction, where said flexible holding device head is held inside said construction; (b) attaching said construction to said implant by fastening the legs of said holding device into said implant; and (c) detaching said construction by applying a pulling force, in an opposite direction to the implant, on said construction.
  • the detaching is done by applying a pulling force on the form with an impression which engulfs the construction.
  • the method is used for connecting and detaching an abutment.
  • the method is used for connecting and detaching an overdenture bar. In one embodiment, the method is used for connecting the overdenture bar to a number of implants which are not parallel to one another in the ridge of the mouth.
  • the present invention also relates to a flexible holding device for connecting a construction to an implant in a ridge of a mouth comprising: (a) a head for holding the construction from the inside of said construction; (b) more than one leg for holding the internal thread of said implant from the inside; and (c) a body, attached to said head and attached to said legs, for attaching said construction to said implant.

  • the dentist is required to take an impression of the ridge and the attached abutment 31, for casting a model of the ridge with its attached abutment 31. Since the model is used afterwards to create the prosthetic tooth 30, the model needs to be as accurate as possible. Any inaccuracy in the model may result in an inaccuracy of the prosthetic tooth which in turn may cause inconvenience to the patient.
  • the dentist may be required to amend and smooth the tooth in the mouth of the patient, after attaching the prosthetic tooth, a feat which is not easy to the dentist and inconvenient to the patient.

  • the impression material which may be any solidifying material such as a combination of Zhermack's Hydrorise silicon and Hydroise putty
  • the material flows around the construction, and in the spaces between the construction and the ridge, and solidifies. This however makes the task, of removing the impression intact and undamaged, time consuming and fairly difficult, since the construction is fastened with screws to the abutments of the implants in the ridge.
  • a device which can hold the construction in place when pouring the impression material, over the construction and ridge, and can easily detach from the ridge, when the impression solidifies, thus allowing the impression to keep engulfing the construction when lifted.
  • the impression which includes the construction, may be used for casting the model of the ridge of the patient, after which the construction may be extracted from the impression and fastened to the model, effectively creating a more accurate model of the ridge and the construction of the patient.
  • These flexible devices are designed to be used instead of the screws used for attaching the construction to the implants.
  • the described device may also spare the use of a transfer since it may be used as a transfer, even in cases where the implants are not implemented in the ridge in parallel.
  • Fig. 5 is a schematic diagram of a flexible holding device, according to an embodiment of the invention.
  • the device 100 is designed as a flexible holding device having a head 11, a body 12, and two extended legs 13.

  • the device of the present invention is beneficial to the dental surgeon who performs the implant surgery, the dental laboratory which creates the dentures, and the patient who receives the denture.
  • the dental surgeon can make an impression much easier since the construction is removed from the ridge along with the impression. With a securely attached construction, difficulty always is encountered with the impression material becoming lodged between the construction and the sutured gingival tissue. Since the construction is removed with the impression, no such difficulties are encountered taking the impression.
  • the dental laboratory can fashion a denture which is much tighter fitting since the construction is present in the laboratory during the denture manufacturing operation. This results in a better fit of the denture for the patient. Installation of the construction, for usage, is accomplished easily by attaching the construction extracted from the impression into the implants in the ridge, prior to the patient being finally fitted with the custom-manufactured denture prosthetic.
