摘要:
The disclosure generally relates to a method for forming a dental mold. The method generally includes: (a) scanning an existing dental structure to generate a three-dimensional first digital model of the existing dental structure, (b) modifying the first digital model of the existing dental structure to generate a three-dimensional second digital model of a planned dental structure; (c) generating a three-dimensional third digital model corresponding to a negative of the second digital model; (d) digitally sectioning the third digital model into at least one buccal model portion and at least one lingual model portion of the third digital model; and (e) creating a dental mold comprising at least one buccal mold portion and at least one lingual mold portion based on the sectioned third digital model. The disclosure also relates to (a) methods of assembling the dental mold over a tooth and a gum of a patient having an existing dental structure in need of dental restoration, (b) methods of performing a dental restoration on the existing dental structure of the patient using the dental mold, and (c) kits including components for forming the dental mold and/or for performing the dental restoration using the dental mold.

A set or assembly for producing at least one temporary crown or bridge material has a carrier for accommodating a crown and bridge material and a crown and bridge material in an amount that is at least sufficient for the production of a tooth crown. The crown and bridge material is a light-curing and, in particular, flowable single-component material, and the carrier that can be adapted to the tooth situation is transparent or translucent. In another aspect, a method for producing a temporary tooth crown or bridge and a temporary tooth crown or bridge produced by the method are also provided.

A cradle, assembly, system and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.

Provided is a removable denture system including a personalized support beam configured to be fixedly attached to an individual's jaw bone by plurality of dental implants; personalized denture conforming with dental parameters of the individual including bottom surface shaped and sized to constitute a super-structure configured for cooperating with the support beam; and denture locking arrangement for securely locking and unlocking the denture to the support beam, one of the support beam and the super-structure includes one or more positioning grooves extending parallel to a path of insert (POI) of the denture, and the other of super-structure and the support beam, includes one or more corresponding laterally projecting positioning projections, each positioning projection configured to cooperate with a corresponding positioning groove, and configured to provide at least partial snug fit together, the support beam and super-structure are configured to eliminate movement when the super-structure is assembled over the support beam.
摘要:
A removable denture system comprising a personalized support beam fixedly attached to an individual's alveolar ridge above the mucous membrane by a plurality of dental implants; a personalized denture conforming with dental parameters of the individual and having fixedly integrated within a bottom surface thereof a super-structure having a cross-section conforming with that of the support beam; and a denture locking arrangement for securely locking and unlocking the denture to the support beam, at substantial zero tolerance therebetween, and wherein one of the support beam and the super-structure is configured with one or more positioning grooves extending parallel to a path of insert (POI) of the denture, and the other of the support beam and the super-structure is configured with corresponding one or more laterally projecting positioning projections, each extending in register with a corresponding positioning grove and configured for snug sliding there within.
摘要:
A dental implant has a hollow shell with outer bio-compatible surface for engaging a soft tissue socket left in gingival tissue after a tooth has been extracted, to promote healing. The shell tapers outwardly from a first to a second perimeter, the second perimeter being asymmetrically scalloped with opposite distal and mesial peaks and opposite lingual and facial valleys between the peaks. A dental implant in the bone socket left after tooth extraction is rigidly connected to a temporary post, the temporary post extending in the shell. The shell engages against the soft tissue socket without gaps and without requiring alignment between the shell and implant axes.

Systems and methods are disclosed for forming a pontic in a pontic-housing pocket of one or more polymeric shell appliances having teeth-receiving cavities. Cavities in the polymeric shell appliances corresponding to the location of a missing or extracted tooth may include a pontic-housing pocket. The pocket may be filled with a composite resin or acrylic material that hardens and presents with a similar visual appearance to a tooth, thereby presenting the illusion that there is no missing tooth. The pontic-hardening pocket may have a single opening of sufficient size for receiving a syringe for injecting the pontic material. After the material hardens and the pontic is formed, it is locked into the pocket, as it cannot fit through the single opening. As the space of a missing tooth is widened or narrowed by the alignment treatment, successive shell appliances may have pontics of successively larger or smaller size.
摘要:
A lower region of a temporary abutment includes an anti-rotational feature for non-rotationally mating with a dental implant. An upper region of the temporary abutment includes a first anti-rotational structure and at least one retention groove. A top surface of the temporary abutment includes one or more informational markers that provide information concerning the dental implant. A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slideably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.
