Embodiment Construction

[0021] While conventional dental restorative techniques typically involve iterative steps and benefit from significant practitioner skill and experience, the present disclosure includes that custom molds can be utilized to facilitate the use of conventional dental restorative techniques more accurately and faster than is generally possible in a patient's A technique for forming dental restorations in the mouth.

[0022] The technique disclosed herein involves capturing a patient's dentition in three dimensions with an intraoral scanner. Custom tools for dental restorations may include molds based on the patient's three-dimensional (3D) dentition. The techniques disclosed herein can facilitate high quality dental restorations with reduced time and skill requirements compared to conventional dental restoration techniques.

[0023] figure 1 is a diagram of a system 10 for detecting and defining tooth structures using digital 3D models based on intraoral 3D scans, or impression...

Abstract

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.

Description

technical field [0001] The present disclosure relates to dental restoration. Background technique [0002] Dental restorations or dental fillings utilize dental restorative materials used to improve the function, integrity and form of missing or irregular tooth structures. For example, dental restorations can be used to restore missing tooth structure after external trauma, or as part of restoration treatment for caries or cavities. [0003] Restorative dentistry traditionally involves drilling the decayed portion out of an infected tooth (often referred to as a "prepared" tooth) and then using simple tools and a high level of craftsmanship to isolate, retract, fill and contour the finished restoration. High-quality isolation via rubber dams is cumbersome, and less effective isolation via cotton dams is often skipped, increasing the risk of contamination that reduces the lifespan of the restoration. Retraction of soft and hard tissues involves manipulation of strings, wedg...
