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.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

The invention relates to a method for producing a denture base semi-finished product with the following steps: 1) Recording and digitalizing the oral cavity situation of a patient, wherein a digital three-dimensional oral cavity model of the patient is produced, or providing a digital three-dimensional oral cavity model of the oral cavity situation of a patient; 2) Implementing a first calculation in which a digital three-dimensional first model (A) of a denture base is calculated, wherein the oral cavity model of the oral cavity situation is used as a basis for the first calculation; 3) Conducting a second calculation, in which a digital three-dimensional second model (B) of a denture base semi-finished product is calculated from the first model (A) of the denture base, wherein volume is added at least in sections to the three-dimensional model (A) of the denture base; and 4) Producing the denture base semi-finished product with a Rapid Prototyping method, wherein with the Rapid Prototyping method, a CAM method is used and the digital three-dimensional second model (B) of the denture semi-finished product is used as the basis for the CAM method. The invention also relates to a device for implementing such a method and a denture base semi-finished product produced using such a method.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.

To provide try-in dentures which make it possible to adjust a bite more easily with high accuracy, a denture base part 12; a dentition part 13; an adjustment part 15; and a base part 14 are included, the adjustment part and the base part being separable from each other, and the adjustment part includes all of occlusal surfaces 13b of the dentition part, and a face 15a parallel to an occlusal plane 10a, the adjustment part being formed so that a movement of the adjustment part parallel to the occlusal plane with respect to the base part can be performed, a rotation of the adjustment part in the face parallel to the occlusal plane can be performed, or both the movement and the rotation can be performed.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.

An abutment system is for attachment to a dental implant having a threaded bore and for engaging the surrounding gingival tissue. The abutment system includes a base and a polymeric abutment cap. The base includes a lower region and an upper region. The lower region includes an anti-rotational feature for non-rotationally mating with one of the dental implants. The upper region includes a first anti-rotational structure and a first axial retention structure. The polymeric abutment cap has a second anti-rotational structure for mating with the first anti-rotational structure and a second axial retention structure for mating with the first axial retention structure. The abutment cap has an upper surface that includes information markers. The information markers define a unique code that provides information concerning the abutment cap and the underlying dental implant.

A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

A method, system and computer readable storage media for proposing and visualizing orthodontic treatments. A patient may use a mobile device such as a smart phone to quickly and inexpensively visualize an orthodontic treatment for misaligned teeth and overlay it on a 3D model of the face and jaw, with a depth sensor being used to detect depth information. The orthodontic treatment may also be visualized in an augmented manner for a clinician. 3D data of the orthodontic treatment may be used for further analysis or fabrication of a treatment appliance.
