Definitions
- the present invention relates in general to dental implants.
- the present invention relates to a system including a dental implant, a customized abutment, an implant analog that is removably attached to a physical model of the mouth of a patient, and a replica of the customized abutment and of the implant analog.
- Fig. 1A is an isometric view of an implant analog according to a preferred embodiment of the present invention.
- Fig. 1B is an elevational view of the side including the face of the implant analog shown in Fig. 1A;
- Fig. 1C is an elevational view of the side of the implant analog shown in Fig. 1A which opposes the side shown in Fig.lB;
- Figs 2A - 2B are two different elevational views of an exemplary retention member providing for fixing the implant analog secured to the base of a physical model of the mouth of a patient;
- Fig. 3 is a schematic view of an exemplary replica of the invention.
- a dental system to be used by care providers for processing a dental prosthesis, while carrying out a dental restoration is provided.
- a dental system of the invention includes an improved implant analog and a replica of a customized abutment mounted therein. Additionally, according to a preferred embodiment of the method of the present invention a replica of this implant analog out of which a segment of a replica of the respective customized abutment protrudes, is provided as well.
- Systems of the invention provide for completing a dental restoration process in which the need to remove a customized abutment off a respective implant is practically avoided. The systems of the invention enable accomplishing an entire dental restoration process up to its final stage without releasing and/or removing the customized abutment off the respective implant.
- means for fast connecting/releasing the implant analog of the invention, to, or off, the respective physical model of the mouth of the patient make the processing of the dental prosthesis less cumbersome, tiresome and easy to operate.
- the dental restoration process considered can be substantially improved; the work of the technician can become more efficient, and less expensive.
- FIGs 1 - 2B an isometric view and two elevational views of improved implant analog 10, which is in accordance with a preferred embodiment of the present invention, are respectively shown.
- the internal surface of the outermost segment of bore 12 need not necessarily be hexagonally shaped, as shown. However, the geometrical shape of this surface is in accordance with the geometrical shape of the respective keying, or orienting surfaces of the abutment to be introduced into the implant considered.
- Bore 12 has a circular rim, which is referred hereinafter as face 14 of implant analog 10.
- Improved implant analog 10 can be oriented in any direction in space.
- the side in which face 14 is located is referred hereinafter as the upper side.
- Pentagon 16 which is circumferential to face 14, is placed closely below face 14.
- Pentagon 16 provides for axially orienting a replica of the abutment that is recombined of fragments of a broken replica (such as typically occurs in cases in which the technician tries to fix a broken replica instead of casting a new one).
- the inner surface of bore 12 is suitably threaded, not shown, such that the abutment considered and/or a replica of the abutment as described infra, can be screwed and firmly secured into the implant analog.
- implant analog 10 is provided with at least two retention members.
- the retention members provide for suitably securing the location and the rotational angle measured relative to an axis of rotation that is perpendicular to the axis of the improved implant analog after being introduced into the physical model of the mouth of a patient, not shown.
- These retention members also provide for respectively snap locking and/or snap releasing the implant analog within, or off, a dedicated receiving bore that is structured in the body of the physical model. Namely these retention members are also used as means for fast connecting/releasing the implant analog, to, or off, the physical model.
- Circumferential groove 18 provides for housing one of these retention members which is an O-ring, not shown.
- This O-ring is made of a resilient material, such as silicon rubber, or Polyether ether ketone (PEEK).
- PEEK Polyether ether ketone
- a spherical male fitting implements retention member 26. It fits in dimensions and geometrical shape with a respective spherical female fitting, which is suitably placed and enclosed within a niche structured at the end of the receiving bore which is adjacent to the base of the physical model. Both of these at least two retention members - the O-ring placed within groove 18 and retention member 26 provide for securing implant analog 10 fixed within the physical model. Any common snap locking mechanism that is locked by pushing and released off by pulling can be employed for fast connecting/releasing and securing the improved implant analog onto the physical model according to the method of the present invention.
- Exemplary is a snap locking mechanism which comprises a stiff ball that is resiliently attached to a side surface of the body of the implant analog, such that it can reciprocally move back and forth in a perpendicular direction to this surface; and a matching recess structured at a side surface of the receiving bore.
- One or more directional members axially disposed across a surface of the improved implant analog provide according to the method of the present invention for suitably orienting the improved implant analog when it is installed within the receiving bore of the physical model.
- Planar contours which are longitudinally disposed across the surface of the body of improved implant analog 10, such as contours 20, provide for suitably guiding and axially orienting implant analog 10 at the suitable and predefined rotational angle relative to its axis, when it is placed within the respective receiving bore of the physical model considered.
- Optional axial grooves such as an elongated groove 24 axially disposed across a surface of the improved implant analog, or an elongated axial ridge, serve for the same guiding and orienting purposes.
- a circumferential keying polygon, such as pentagon 16 is less favorable for axially orienting the improved implant analog because the polygon may comply with more than one rotational angle.
- a passageway connects between the lumen of bore 12 its surface is threaded as described hereinabove, and aperture 32 which is disposed at the bottom of retention member 26. This passageway provides for releasing excessive pressure when a replica of the abutment is casted, in cases in which the lumen of the implant analog is used as a mold for such casting.
- the body of an implant analog in accordance with a preferred embodiment of the present invention is made of polished stainless steel, or a hard metal such as titanium. Improved implant analogs their bodies are made of stiff plastic resin, and or common dental composite materials are in accordance of the present invention.
- Figs 2A - 2B two elevational views of the female fitting 40 of retention member 26 are respectively shown.
- the body of female fitting 40 is made of resilient material. Therefore this female fitting provides for snap engaging the spherical retention member 26 of implant analog 10 described above.
- Female fitting 40 is a spherical recess structured in cube 41 that can be removably attached to the body of the physical model. Alternatively such spherical recess is structured within a cylinder that is structured and arranged to be installed at the end of the receiving bore that is adjacent to the base of the physical model.
- Aperture 42 is disposed at a plane located at a predefined level above the base of the physical model considered.
- retention member 26 In cases that retention member 26 is engaged with its spherical female fitting 40 it provides for supporting the implant analog at the desired and predefined height measured relative to the impression of the gum and for strengthening the connection between the implant analog and the body of the physical model. Such support and mechanical strengthening are required when the technician processes by say, milling, the abutment for its customization; or when the technician presses it in the course of processing of the respective dental prosthesis.
- Female fitting 40 provides for fixing the face of implant analog 10 at the suitable level above the base of the physical model considered. The dimensions and geometrical shape of the body of retention member 26 fit in with the dimensions and shape of the respective female fitting 40.
- the radius of circular aperture 42 which is the aperture of the spherical niche that is centrally disposed at the upper face of female fitting 40, is somewhat smaller compared to the radius of the male spherical retention member of the implant analog considered.
- the radius of the spherical niche closely fits in with the radius of the spherical retention member 26. Therefore whenever the implant analog is forced towards the base of the physical model spherical retention member 26 snap engages the respective niche with a "tician". Pulling the implant analog in the opposite direction frees the spherical retention member off the spherical niche.
- Female fitting 40 is made of resilient material such as nylon or polyether ether ketone (PEEK).
- a customized abutment is derived in accordance with the relevant clinical data of a patient (e.g., teeth, edentulous ridges, gums and especially the first impression of the gum that is taken after the gum and bone at the periphery of the implant has fully recovered) as known.
- a common abutment is first mounted onto the improved implant analog.
- the implant analog including the abutment installed therein is mounted and secured onto the physical model.
- the connection between the abutment and the implant analog is secured by screwing at a predefined level of rotational torque, as known.
- Such mounting is accomplished 5 prior to the initiation of the processing of the abutment, such as by milling.
- the customized abutment can be fixed firmly within the implant.
- the customized abutment, following its mounting onto the implant is first used for carrying for example a temporary crown.
- the technician casts according to the method of the present invention a replica of the abutment.
- a replica of the abutment is accomplished according to a preferred embodiment of the method of the present invention by employing a mold which comprises the improved implant analog as well as the negative impression of the segment of the abutment which protrudes off the i s implant analog.
- Materials normally utilized for such casting may include according to the method of the present invention dental composite materials commonly used in dentistry as restorative materials or adhesives. From the moment in which the casting of the replica of the custom abutment has been accomplished, the implant analog is firmly connected to the replica of the
- Fig. 3 schematic view of replica 50 of a custom abutment according to a preferred embodiment of the present invention is shown.
- Segment 51 of the replica of the custom abutment protrudes off improved implant analog 52.
- Edge 54 is the end of fully exposed segment 51 that protrudes off body 52 of the improved implant analog.
- a partial segment of segment 51 one end of which is edge 54 encloses the pentagon described hereinabove.
- the rest of the body of the casted replica of the abutment considered, not shown, is fully enclosed within the lumen of body 52 of the improved implant analog.
- the rest of the body of the replica is referred hereinafter as the internal segment of the replica of the custom abutment.
- an integral unit of the replica of the improved implant analog out of which a segment of the customized abutment protrudes is casted according to another preferred embodiment of the method of the present invention.
- This integral unit is referred hereinafter as the replica according to the second preferred embodiment.
- This casted unit substitutes the replica of the abutment that is casted into the lumen of the implant analog according to the first embodiment of the method of the present invention described above.
- the integral unit is employed in accordance with this second preferred embodiment of the present invention for supporting the very dental prosthesis in the course of its preparation.
- the replica according to the second embodiment of the method of the present invention includes segment 51 as well as body 52. Both of these two segments are integrally connected to each other and both of them are made of the same material.
- the dental prosthesis is attached to the physical model of the mouth of the patient for its evaluation following each accomplished step in the process of its preparation, as known. Such attaching is accomplished by means of a casted replica according to any of these two preferred embodiments of the method of the present invention described above.
