Patent Application
20150351878
This disclosed subject matter relates to dental implants in general and in particular to a device for adjusting and/or manipulating portions of dental implant assembly about its various parts.
In its simplest form dental implant assembly and/or system are known in the art and typically include a dental anchor that is securely inserted into the patient jawbone, replacing the root, a restoration that replaces the tooth crown and an abutment and/or pivot member that interface both the anchor and restoration. Commonly, in the art, the abutment is affixed to the anchor through a fixation screw also known as an abutment screw.
A multitude of prefabricated abutments and implant systems of various designs are offered to clinicians in an effort to provide clinicians with necessary means to successfully restore edentulous patients.
In order to be successful, the implant anchor and all restorative devices associated therewith, should meet specific functional, biological and esthetic requirements. These requirements may be achieved if the restorative implant system, and/or devices used on the implants, adhere to major biomechanical principles, including: Preservation of implant structure; Passive retention and Passive support; Resistance form; Structural durability of the restoration; Marginal integrity and emerging profiling (marginal compliance); Retrievability and Retrofitting; Individuality; Preservation of the perio-implant tissues. Therefore, for a successful implant procedure to take place, the above mentioned biomechanical principles must be met.
A number of factors in the design of the abutments determine if a restoration can adhere to the previously mentioned biomechanical principles in order to achieve the desired functional, biological and esthetic requirements. For example, the abutment's connection to the anchor platforms has an effect on the abutment's position and stability.
Prior art abutments and/or restorative systems and/or portions thereof do not meet the above mentioned bio mechanical principals, leading to major drawbacks in the quality of the restoration. Due to these limitations, clinicians are forced to compromise the functional, biologic and esthetic requirements of the restoration. Such compromises may for example result in or lead to: shortening the survivability and/or viability of the implant, irreparable damage to host tissue; damaged implant structures, the requirement of laborious and prolong multi-stage and multiple surgical procedures, reduce access for maintenance of the host tissues, makes it very difficult and often impossible to maintain an implant's assembly elements and substantially increase costs.
Prior dental implant systems generate major drawbacks by providing unstable connection platforms and limited designs of abutments which restrict the abutment's shape, level of angulation and provide limited directionality control relative to the patient, and therefore cannot be customized to the patient. Prior art dental implant systems substantially limit clinician's options to properly position an abutment (and the restoration mounted thereon) relative to other abutments and/or teeth of same and/or opposite jaw. Prior art dental implant systems do not provide an abutment assembly that may be adjusted and/or customized with respect to individual morphology, specific clinical situation of the patient and according the biomechanical principles.
Similarly, current abutments do not allow for, parallel alignment between abutments and/or associated prepared teeth, and/or other teeth involved in the rehabilitation process. Proper shape, adequate position and/or parallel alignment are essential for providing the restoration with the attributes necessary to achieve the prosthodontics requirements according the biomechanical principles.
In order to enable rehabilitation prior restoration systems, abutments must have their position and/or alignment improved by additional adjustments (by milling and/or casting), resulting in another major drawback. The adjustments made by milling and/or casting causes the disruption of the shape and geometry of the prior art abutment and implant assembly, specifically, the formation of undercuts and/or irregularities leads to the reduction of abutment to restoration contact surface (therein leading to poor retention) and incomplete seating of restoration (leading to lower durability of restoration and percolation of fluids).
Similarly, prior art abutments do not allow for the finish line to be individually adjusted in relation with the bone level, soft tissues, abutment's axis, and the occlusal plane, thus impeding the achievement of an adequate smooth well positioned finish line with proper width to receive the encountered forces and closely fit with restoration's margins.
The unstable connection systems and the lack of or inadequate finish line of prior systems causes gaps between the different implant system parts (for example between the anchor and abutment; restoration margins and abutment finish line) that lead to: percolation and retention of fluids and pathogens into implant-restoration structure about the vicinity of host tissue; irritation, inflammation and damage to perio-implant tissue; bad odor; bad taste; and damage to implant's elements and/or structures. Furthermore, prior systems lack a finish line altogether, resulting in weak, over contoured restoration margins which intrude perio-implant tissues, increasing food and plaque retention. Prior art systems provide limited options of standardized prefabricated pre-positioned finish lines, thus defining standard transmucosal abutment portion (abutment collar) which does not and cannot take into account various clinical situations. Moreover, a prefabricated finish line provided with prior art abutments does not provide for the improvement of the marginal seal, the formation of a healthy biologic width, and the required direction imperative to provide passive support to encountering forces. Embodiments of the presently disclosed invention overcome the deficiencies of the prior art dental implant systems.
The presently disclosed subject matter relates to dental tools and methods of their use, that facilitate customizing and/or adjusting and/or manipulating a dental implant system or any of its members and/or elements and/or constituents, for example an adjustable implant abutment assembly or any elements thereof.

Most preferably the tools of the present invention allow an abutment assembly to be adjusted so as to assume a position that is substantially perpendicular to the occlusal plane and just about parallel with adjacent and/or other abutments and/or teeth. Thus essentially, the tools facilitate defining only one path of insertion and retrievability that is substantially parallel to the axis of the abutment and/or abutments.
The aforementioned positioning and/or parallel alignment of abutments and/or teeth in addition with the aforementioned position of the finish line provides the restoration with complete sitting, and allow the restoration margins to lie and closely fit against the finish line, synergistically increasing the, passivity of the retention, the passivity of the support and the resistance form, and determine that the implant structures, the implant elements and perio-implant tissues are not subject to harmful impact such as tension, sheer force, compression or torque
By allowing the creation of one path of insertion and retrievability and a well-defined finish line most preferably the tools according to the present invention, provide for retrievability and retrofitting of a restoration. One path of insertion and retrievability preferably provides for improving the continuing maintenance of the implant, for example including but not limited to, replacement of the abutment or other prosthodontic elements, performance of additional surgical procedures, exercising hygienic evaluation, allow for the adjustment of the restoration in case an implant is lost, the like or any combination thereof.
