Each guide tab fits in the top portion of one of the mold holes and each tissue punch head fits in the top portion of one of the mold holes. A method of placing dental implants is also described.
OSSEOINTEGRATIVE SURGICAL IMPLANT
Embodiments of the present invention provide an osseointegrative implant and related tools, components and fabrication techniques for surgical bone fixation and dental restoration purposes. In one embodiment an all-ceramic single-stage threaded or press-fit implant is provided having finely detailed surface features formed by ceramic injection molding and/or spark plasma sintering of a powder compact or green body comprising finely powdered zirconia. In another embodiment a two-stage threaded implant is provided having an exterior shell or body formed substantially entirely of ceramic and/or CNT-reinforced ceramic composite material. The implant may include one or more frictionally anisotropic bone-engaging surfaces. In another embodiment a densely sintered ceramic implant is provided wherein, prior to sintering, the porous debound green body is exposed to ions and/or particles of silver, gold, titanium, zirconia, YSZ, -tricalcium phosphate, hydroxyapatite, carbon, carbon nanotubes, and/or other particles which remain lodged in the implant surface after sintering. Optionally, at least the supragingival portions of an all-ceramic implant are configured to have high translucence in the visible light range. Optionally, at least the bone-engaging portions of an all-ceramic implant are coated with a fused layer of titanium oxide.
ATTACHMENT MEMBERS WITH INTERNALLY LOCATED RADIOPAQUE INFORMATION MARKERS FOR CT SCAN
An attachment member for mating with a dental implant includes a non-rotational structure and a body. The non-rotational structure is configured to mate with a corresponding non-rotational feature of the dental implant. The body extends from the non-rotational structure. The body has (i) an exterior side surface configured to at least partially engage gingival tissue adjacent to the dental implant, (ii) an exterior top surface that is exposed through the gingival tissue, (iii) a screw access bore for receiving a screw that attaches the attachment member to the dental implant in a removable fashion, and (iv) a set of radiopaque information markers that is located internal to the exterior side surface and the exterior top surface. The set of radiopaque information markers indicates information regarding the dental implant that is revealed in response to a scan from a computerized tomography (CT) scanner.
BONDING OF SOFT GINGIVAL TISSUES WITH ANATOMICAL AND OTHER DENTAL PROSTHESES
Methods and dental prosthetics for providing soft tissue adhesion to a temporary healing abutment, or other dental prosthetic (e.g., temporary or permanent). Existing prosthetics generally do not provide any significant adhesion of the soft tissue surrounding the prosthetic, to the outer surface of the prosthetic itself. Because of the presence of gaps between such structures, or simple non-adhesion even where the structures may touch (but be free and unattached relative to one another), there is a tendency for pathogenic microbes to enter into such space between the structures, and for the soft gingival tissue to recede, particularly in patients with thin type periodontal tissue. The present disclosure provides materials and/or surface treatment (e.g., texturing) that ensures good bonding between the prosthetic and the soft tissue, reducing risk of infection, and reducing undesirable gingival recession surrounding the prosthetic anchored on a dental implant.
Universal aligning adaptor system and methods
A system for dental implant restoration is provided. It includes universal aligning adaptors and prosthetic components having co-operable indices, which together form a translational, integrating system which aligns, synchronizes, and references the prosthetic components about an implant's central axis of rotation. Rotation of an adaptor about a prosthetic component, with its reference point becoming aligned to a predetermined reference point on the prosthetic component, followed by the rotation of the adaptor/prosthetic component assembly about the implant, situates the prosthetic component in a predetermined position such that all other prosthetic components become synchronized to the adaptor's reference point. The prosthetic component is mechanical for clinical or lab bench use, or is virtual for restoration design in a software program, prior to milling prosthetic abutments or devices. Abutments, healing caps and screw access holes are realigned to preferred positions and synchronized with minimal deviation from the ideal direction.
Removable system and method for dentures and surgical guides
A removable system and method for helping position and stabilize implant supported dentures during the healing process after surgery is provided, wherein a removable system comprises a soft tissue supported provisional denture structure configured to help position and stabilize the provisional denture during the transfer of the implant positions to the provisional denture. In the surgical process of providing implant-supported dentures, immediately after the implants are surgically implanted, adhesive is applied to the underside of the provisional denture, and implant connectors are seated on the implants. The provisional denture is seated in the patient's mouth wherein the soft tissue supported provisional denture structure helps stabilize and position the denture. The implant connectors adhere to the adhesive and transfer the implant positions to the provisional denture.
GINGIVA HEALING ABUTMENT FOR A DENTAL IMPLANT
A healing abutment configured to be provided in an implant prior to fitting a prosthetic tooth and comprising a leg and a head which are aligned along an axis Z and connected by means of a tensioning screw, the leg comprising a lower leg portion configured to cooperate with the implant, the head comprising a lower head portion configured to cooperate with an upper portion of the leg, the healing abutment comprising a reference member which defines a reference point and is configured to cooperate with the leg in order to define a plurality of basic reference point positions and is movably mounted relative to an upper portion of the head having a predetermined shape in order to allow the selection of at least one optimum basic position from the plurality of basic positions.
CUSTOM DENTAL COMPONENT AND SCAN BODY
A custom dental component and scan body for supporting the soft tissue surrounding an implant that is installed in at least a portion of a patient's jaw bone during the dental restoration process. The custom dental component includes a custom subgingival emergence profile so as to support and train the surrounding soft tissue. The custom dental component, while remaining connected with the implant, is scanned or an impression is obtained. A three-dimensional digital model of the patient's detention is produced from the scan or impression. A dental design software is used to view the three-dimensional digital model. A digitally-designed custom dental component is imported in the three-dimensional digital model and aligned with the custom dental component to obtain the implant's position.
Gingival Tissue Former
A process for providing a gingival tissue former may include, but is not limited to: capturing a cross-sectional image of a representation of a tooth in a digital scan, perpendicular to a reference axis, at a specified reference level; modifying an orientation of the cross-sectional image to correspond to a standard orientation; applying one or more image processing techniques to the cross-sectional image to generate a tooth shape image; and mapping the tooth shape image to one or more design specifications for a gingival tissue former.
