A system and method for manufacturing a physical model of a dental structure wherein the physical model is configured to allow a dental analog to be inserted into the physical model. A virtual model of the dental structure is provided including a virtual implant spatial disposition with respect to the virtual model corresponding to a physical implant spatial disposition of the dental implant. Using the virtual model, a physical model corresponding to the virtual model is manufactured, the physical model being provided with a physical analog corresponding to the virtual analog. The physical analog installation structure is configured for enabling a dental analog, corresponding to the dental implant, to be inserted. In the installed position, the dental analog has an analog spatial disposition with respect to the physical model corresponding to the physical disposition of the dental implant with respect to the physical dental structure.

The invention relates to a screw and corresponding screw driver for driving the screw into a dental implant at an angle from the longitudinal axis of the implant. The screw has a polygonal interface and the screw driver has a matching interface for driving the screw to rotate.

A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.

The present invention relates to a digital scan body alignment method and a device using the same. The present invention corrects scan data through library data corresponding to image data on oral structure. At that time, to achieve best-fit of aligning the library data to the scan data initially, the data alignment can be performed by using a first alignment step. In order to accomplish data correction by more accurate data alignment, a second alignment step can be performed using the library data which includes shape information and axis information. By performing the second alignment step, corrected data having higher reliability can be formed, and a more precise prosthesis can be provided to a patient.

The invention relates to a scan abutment (2), in particular an integrally manufactured scan abutment, for determination of the position of the front face (1.1) of a dental endosseous implant (1), wherein the abutment (2) has a longish, hollow shaft (4), and the shaft has an upper region (4.1), a central region (4.2) and a lower region (4.3). Moreover, the shaft (4) of the scan abutment with its central region (4.2) is attachable onto the front face (1.1) of the implant (1), and its lower region (4.3) is insertable into the connection geometry of the implant. The longish, hollow shaft (4) has a side wall (10). The shaft of the scan abutment has at least two to terminally extending slits (5) in its central region (4.2) and lower region (4.3) in the side wall (10). Two, three or four slits are preferred. Preferably, the slits (5) end in one recess (6) each, such as a circular recess, in the side wall (10) at their upper end and extend terminally in the side wall (10) to the bottom side of the shaft (4). Another subject matter of the invention is a kit comprising a scan abutment as well as the screw adjusted to the scan abutment or the bolt adjusted to the scan abutment.

A substantially tubular intermediate attachment part with a first through-hole for attaching a screw-retained dental prosthetic component or a dental tool to a dental implant or to a dental implant analog, extending along a first longitudinal axis between a first end and a second end. Each end is provided with a set of longitudinal fins intended for snap-fitting into the dental prosthetic component or into the dental tool on the one hand and into the dental implant on the other hand.

A multi-component dental implant system designed to improve oral hygiene. The dental implant system may comprise an implant body configured to be insertable into at least a portion of an individual's mouth, a primary or first abutment, a dental prosthesis engagement member, and a housing assembly. In use, the first abutment is designed to engage with and secure to the dental prosthesis engagement member. The housing is configured to secure to or cover the dental prosthesis engagement member. The dental implant system allows an individual to remove a prosthesis without the aid of any special tools or instruments.

A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.

A dental implant system has a dental implant (1) provided with an implant frustoconical cavity (2); an abutment (19) having an abutment post (20) of size and shape such as to be permanently retained in the implant frustoconical cavity (2) and an abutment head (22) suitable for supporting a dental crown (13); a dental transfer (4) having a transfer post (5) intended to be inserted into the implant frustoconical cavity (2) before an impression taking, and a transfer head (7) identical to the abutment head (22) of the abutment (19); and an implant analog (11) having an analog internal cavity (16) suitable for receiving the transfer post (5), and an outer surface (14) provided with undercuts (15) to be retained inside a plaster model (12) in casting a dental model into said impression. The implant frustoconical cavity (2) of the dental implant (1) is a through hole.

A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.
