To easily and appropriately position a dental prosthesis and an abutment, and to appropriately prevent misalignment of the dental prosthesis with the abutment.SOLUTION: A dental abutment 20 includes: a base 21 fixed to an implant fixture 10 embedded in an alveolar bone 1; and an embedding part 22 fixed to an embedding hole 33 provided in a dental prosthesis 30. The implanting portion 22 includes a first flat surface 23a, a second flat surface 23b, and a spring member 24. The first flat surface 23a, the second flat surface 23b corresponding to the first flat surface 35a and the second flat surface 35b are provided in the embedding hole 33. When the embedded portion 22 is inserted into the embedding hole 33, the spring member 24 biases an embedded portion 23 in a direction in which the first flat surface 23a and the second flat surface 23b are pressed against the first flat surface 35a and the second flat surface 35b.SELECTED DRAWING: Figure 1

The present invention relates to the field of devices for implantation. More specifically, the invention provides a scan body or scanning abutment for dental implants, which is suited for high precision inter-oral scanning while mounted on a dental implant. The scan body is also suited for scanning when mounted on an implant analog, e.g. mounted in a model of the patient's mouth.

An omni-abutment includes (i) an apical connection portion that mates / attaches with the receiving portion on a corresponding implant; and (ii) a coronal superstructure. The dental abutment provides features that are not currently found in abutments on the market, allowing the abutment to be used as a key foundation for scanning, impression taking, stability testing, and much more which ultimately would lead to an easier restorative process and fabrication of a dental prosthesis. The abutment could also be used for fabrication of a final prosthesis. The abutment may include alignment indents or protrusions in a platform thereof, internal grooves (e.g., square or rounded) as a tri-lobe or other configuration in the central axial hollow channel, recesses (e.g., divots, grooves) in the exterior periphery for increased adhesion to a gingival healing cuff, internal threading in the hollow channel, and a hex, NC or other connection at the apical connection portion.

Through the arrangement of the contact component and the positioning component, the purpose of synchronous strengthening restriction and guide positioning installation of the implant dental abutment is achieved.

Disclosed is a method for providing a dental abutment by using data about a customized abutment, comprising the steps of: receiving oral data about a patient; and acquiring a standardized abutment from a standardized abutment group generated from the customized abutment in correspondence with the inputted oral data about the patient.

The present invention relates to the field of implant devices. More specifically, the invention provides a scanning body or scanning abutment for dental implants, suitable for high-precision intraoral scanning when mounted on a dental implant. The scanning body is also suitable for scanning when mounted on an implant analogue, for example, mounted on a model of the patient's mouth.

Example dental assemblies and methods involve snap-fitting a denture or other dental prosthesis to a patient's jaw. In some examples, an implant is anchored to the jaw, an abutment is screwed to the implant, and a head of the abutment snaps directly into a pocket created in the dental prosthesis. In some examples, a polymeric cap couples the abutment's head to the pocket. Based on coordinate data from a CT or intraoral scanner, the pocket can be created by CNC milling or 3D printing. The method eliminates the need for bonding a metal housing or casing to the dental prosthesis.

This invention discloses a data-driven modeling method for deformation of the stress surface of a dental abutment, belonging to the field of digital modeling. The method includes: acquiring geometric structure, material properties, and clinical stress data of the dental abutment through non-contact 3D scanning and dynamic force sensing technology; constructing a standardized dataset after preprocessing; and annotating deformation features with clinical experience. By extracting core features and expanding the sample by fusing virtual and real data, a data-driven deformation prediction model is established, utilizing a small-sample adaptation framework and attention mechanism to achieve high-precision nonlinear mapping. After clinical sample validation and iterative optimization, the model has adaptive update capabilities and can be applied to abutment design, installation calibration, and stability monitoring. The advantages of this invention are: based on multi-dimensional clinical data acquisition, preprocessing, and expansion, combined with a small-sample-adaptive modeling framework and attention mechanism, accurate deformation prediction is achieved; after optimization and updating, it is adapted to clinical scenarios, assisting in abutment design and treatment.

The present disclosure discloses an orthodontic space maintainer (100), and methods for preparing the same and preserving inter-dental spacing. The orthodontic space maintainer (100) includes an orthodontic band (102) configured to be circumferentially secured to a dental abutment, wherein the orthodontic band (102) features an outer surface (110) and a contoured inner surface (112) adapted to morphology and conforming to variable angulations within the dental arch. A tubular member (104) is securely affixed to the outer surface of the orthodontic band and extends in a direction opposite to the outer surface of the orthodontic band, the tubular member (104) being configured as a reception port. An adjustable loop (106) with a proximal end and a distal end is also provided, wherein the tubular member (104) receives the proximal end of the adjustable loop (106), and the proximal end is configured for mechanically securing the adjustable loop (106) within the tubular member to establish a fixed spatial relationship.
