The invention also relates to the production of the implant preform made of plastic and also to the use of the implant preform as an implant or for fabrication of an implant therefrom, more particularly to the use thereof as a dental implant or for fabrication of a dental implant. The invention can also be applied to other bone implants.

  • Patent number: 10595970
    Abstract: 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.

  • Patent number: 10575931
    Abstract: A partially customizable single-piece dental implant includes a preformed bone-anchorage component and an abutment component that is custom milled from a block either preoperatively, (i.e., Process A) or intraoperatively, (i.e., Process B). In Process A, the planned abutment shape is designed by a computer-aided design (CAD) software based on a computerized tomographic scan and other patient data. Alternatively, under Process B, the position of the planned implant with respect to the alveolus is digitally captured (e.g., by an optical impression device or an intraoperative computerized tomographic scan). In both Process A and Process B, a blank implant having the millable block is held to allow a computer-aided manufacturing (CAM) machine to customize the abutment component, as well as part of the bone-anchorage component. The resultant dental implant is then inserted in the alveolus and either a provisional or permanent prosthesis can then be immediately loaded on the implant.

  • Patent number: 10561478
    Abstract: Taking a digital implant or abutment level digital impression by means of intra-oral, computed tomography or other imaging method provides the restorative doctor and laboratory accurate and effective data for determining the implant position, angulation and locking feature orientation without a physical impression. Such data is correlated with a digital library to produce an output which enables design and fabrication of an accurate restorative device such as a prosthetic tooth or crown. In this way the time-consuming, costly and error prone mechanical replication of the relevant dental anatomy is obviated.

  • Patent number: 10543061
    Abstract: The present disclosure provides engineered surfaces that exhibit reduced specular reflection and gloss while still providing a high intensity of reflected light at multiple incident angles. The structured metal surfaces include engineered topography that increases diffuse reflection, leading to a greater intensity of light perceived at multiple viewing angles. A viewer engaging such surfaces is likely to perceive a stronger ‘white’ reflection of the incident light and an improvement, particularly in orthodontic and other oral applications, of aesthetic appearance. Methods of creating the engineered surfaces and orthodontic articles incorporating the engineered surfaces are also disclosed.

  • Patent number: 10543063
    Abstract: A dental prosthesis arrangement includes a lower part assigned to a jaw implant and an upper part assigned to a superstructure. The lower part engages in the upper part along a central axis. The lower part is supported against the upper part at several contact faces. The lower part and the upper part are connected releasably to each other via a securing device which provides a retaining force against axial withdrawal of the upper part from the lower part. A first radially inwardly directed structure is provided on the lower part and a second radially outwardly directed structure is provided on the upper part for receiving a holding element that provides the retaining force. A fastener passing through the upper part and connected to the lower part can alternatively fix the upper part to the lower part.
