Dental restoration molding techniques

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

BONE-MOUNTED DENTAL ARCH VENEERS AND METHODS FOR FABRICATING AND UTILIZING THE SAME
20200222158 · 2020-07-16 ·

Bone-secured dental arch veneers and methods for fabricating and utilizing the same. The dental arch veneers include a veneer assembly having one or more tooth veneers and a support structure configured to support the tooth veneer(s). The dental arch veneers also include a coupling structure configured to interconnect the veneer assembly to a bone mount that is anchored along a user's maxilla or mandible. The coupling structure also is configured to permit the veneer assembly to be selectively and repeatedly interconnected with and disconnected from the bone mount. The methods include determining a target region within the user's mouth, obtaining a representation of the target region, manipulating the representation to create a desired arrangement of the user's teeth within the target region, determining anchoring positions proximate the target region for anchoring the bone mount, and forming the dental arch veneer based on the anchoring positions and the desired arrangement.
