## Abstract

A system and method and system for providing preoperative patient intraoral scanning for diagnosis and preparation of a treatment plan utilizing the proposed system in advance of the crown surgery and intraoperative patient intraoral scanning for system assessment and verification for the method of treatment. More specifically, the proposed invention proposes a method and system of patient intraoral scanning to identify the best prefabricated crown for use for the patient and develop a plan for intraoral surface treatment for the identified prefabricated crown and automated crown inventory management.

## Claims

### Claim 1

A computerized system for treatment plan for pediatric crown surgery using a prefabricated crown replacement, the system comprising:
a server having a memory storing an inventory database of multiple prefabricated crown replacements;
a computing device having at least one processor and a display, the computing device configured to communicate with the server;
an intraoral scanner in communication with the computing device;
a platform in communication with the server and accessible via a network by the computing device, wherein the platform comprises:
a user interface configured to receive and display a digital image of a three-dimensional representation of a patient's teeth as captured by the computerized system;
a user interface tool configured to digitally remove a selected patient tooth to create an open space and digitally analyze the open space;
an inventory menu displaying multiple prefabricated crown replacements from the inventory database for digital selection by the user;
the user interface further configured to display an image of a digitally selected prefabricated crown replacement in the open space;
a user interface tool configured to analyze the size and shape of the selected patient tooth and the interior size and interior shape of the digitally selected prefabricated crown replacement and prepare a digital tooth preparation form based on the analysis;
the user interface further configured to display an image of a digital image of a three-dimensional representation of a patient's tooth preparation as captured by the computerized system prior to placement of the digitally selected prefabricated crown replacement; and
a user interface tool configured to superimpose the patient's tooth preparation and the digital tooth preparation form during the patient's tooth preparation to provide topographical color analysis of areas on the patient's tooth preparation needing further reduction prior to placement of the selected prefabricated crown replacement.

### Claim 2 (depends on 1)

The system of claim 1, the inventory database further including the characteristics of the multiple prefabricated crown replacements including size, image, tooth type, color, interior crown shape and interior crown size.

### Claim 3 (depends on 2)

The system of claim 2, multiple prefabricated crown replacements displayed by the inventory menu further being selected from the inventory database based upon the characteristics of the multiple prefabricated crown replacements and the digital analysis of the open space.

### Claim 4 (depends on 1)

The system of claim 1, further comprising an automatic reordering tool configured to reorder the digitally selected prefabricated crown replacement.

### Claim 5

A computing device implemented method for providing a pediatric crown surgery using a prefabricated crown replacement, the computing device implemented method comprising:
preparing a digital scan of a patient's teeth using an intraoral scanner configured to transmit digital image to a computing device;
digitally identifying a selected patient tooth on the digital scan of the patient's teeth for a selected patient tooth for replacement;
determining parameters of the digital open space on the digital scan;
identifying for selection at least one prefabricated crown replacement from a stored inventory of prefabricated crown listings accessible by the computing device;
analyzing the size and shape of the selected patient tooth and the interior size and interior shape of the selected prefabricated crown replacement and preparing a digital tooth preparation form based on the analysis;
preparing a digital scan of a patient's tooth preparation using an intraoral scanner; and
superimposing the digital tooth preparation form and the digital scan of the patient's tooth preparation during the patient's tooth preparation to provide a topographical color analysis of areas on the patient's tooth preparation needing further reduction prior to placement of the selected prefabricated crown replacement.

### Claim 6 (depends on 5)

The method of claim 5, the at least one prefabricated crown replacement identified based upon the determined parameters of the selected patient tooth.

### Claim 7 (depends on 5)

The method of claim 5, reordering the selected prefabricated crown replacement.

### Claim 8

A platform in communication with a server and accessible via a network by a computing device for use in conjunction with pediatric crown surgery using a prefabricated crown replacement, the platform comprising:
a user interface configured to receive and display a digital image of a three- dimensional representation of a patient's teeth;
a user interface tool configured to digitally identify a selected patient tooth occupying a defined space and digitally analyze the defined space;
an inventory menu displaying multiple prefabricated crown replacements for digital selection by the user;
the user interface further configured to display an image of a digitally selected prefabricated crown replacement in the defined space;
a user interface tool configured to analyze the interior size and interior shape of the digitally selected prefabricated crown replacement and prepare a digital tooth preparation form based on the analysis;
the user interface further configured to display an image of a digital image of a three-dimensional representation of a patient's tooth preparation prior to placement of the digitally selected prefabricated crown replacement; and
a user interface tool configured to provide topographical color analysis of areas on the patient's tooth preparation needing further reduction during the patient's tooth preparation and prior to placement of the selected prefabricated crown replacement.

### Claim 9 (depends on 8)

The platform of claim 8, further comprising a user interface tool configured to analyze the size and shape of the selected patient tooth and the interior size and interior shape of the digitally selected prefabricated crown replacement and prepare a digital tooth preparation form based on the analysis.

### Claim 10 (depends on 8)

The platform of claim 8, further comprising a user interface tool configured to superimpose the patient's tooth preparation and the digital tooth preparation form to provide topographical color analysis of areas on the patient's tooth preparation needing further reduction prior to placement of the selected prefabricated crown replacement.

### Claim 11 (depends on 8)

The platform of claim 8, further comprising an automatic reordering tool configured to reorder the digitally selected prefabricated crown replacement.
