General description

Maestro 3D Dental Studio Expert is a software based on a totally proprietary technology and it represents a complete tool for the realization of orthodontic treatments and for the design of aesthetic and functional dental appliances based on individual dental anatomy of the patients.

The software includes two working areas: Order Management and Dental Studio.

The Order Management is the application for managing the customer database, creating a new work case and opening an existing one. This software application does not have a medical purpose, as defined in MDR Regulation, so it does not fall within the definition of a medical device.

Maestro 3D Dental Studio Expert can import digital 3D files from 3D scans and 2D images (as patients photos), then it analyzes, modifies the input files with the aim to create a set of 3D models needed for orthodontic and restorative treatments. The 3D input files can originate from 3D intraoral or extraoral scanner, in particular structured light or laser scanner.

Maestro 3D Dental Studio Expert is a tool that allows predictable results (through the creation of 3D models), improving communication between the dental technician, doctor and patient. The software is modular and it is composed by two main macro modules: Ortho Studio and Smile Creator.

Maestro 3D Dental Studio Expert is a stand-alone software which is not distributed by a physical support. It is distributed to the customer by sending through email the link to download the information material and the executable file of the software. So, the software does not require any packaging. At the same time, Age Solutions provides a dongle USB as protective hardware for use. This latter is defined as an accessory of a medical device and classified accordingly.

Intended use

The software Maestro 3D Dental Studio Expert is a medical device intended to be used exclusively by qualified personnel (dental technicians and dentists) to provide information to take decisions for the diagnosis and planning of orthodontic treatments and for the design of aesthetic and functional dental appliances based on individual dental anatomy of the patients.

In particular, Maestro 3D Dental Studio Expert software allows the technician/dentist:

• to create 3D models (according to the orthodontics standard Parallel, Tweed, Ricketts, ABO);
• to perform the analysis of specific parameters on 3D models (e.g. mesodistal distances, root lengths, intersections, etc.), in order to make decision about the orthodontic treatment to carry out;
• to simulate the teeth repositioning in order to plan the appropriate type of treatment;
• to automatically generate a sequence of transition models from the initial position to the final position (the number of transition models is determined by the maximum movement constraints that each transition model can perform);
• to compare the current position of the teeth (during orthodontic treatment) with the initial position, in order to evaluate the progress of the treatment.
  

Maestro 3D Dental Studio Expert can import digital 3D files from 3D scans and 2D images (as patients photos), then it analyzes, modifies the input files with the aim to create a set of 3D models needed for orthodontic and restorative treatments. The 3D input files can originate from 3D intraoral or extraoral scanner, in particular structured light or laser scanner.

Therefore, the software is intended to guide and assist the user (dental technician/dentist) in planning and design of orthodontic treatments and devices as listed below:

• templates for the positioning of orthodontic brackets,
• clear aligners,
• bite anti-bruxism,
• templates for the realization of total mobile prosthesis.

Intended users

The described device is a stand-alone software intended to be used only by qualified personnel represented by dental technicians (mostly) and dentists. Therefore, it is recommended that the user has the appropriate expertise and training in orthodontic and prosthetic dentistry. Furthermore, it is important that the user is familiar with the use of 3D digital technologies.

The dentist and the dental technician can use the software in the same way and all the functions available for the purposes of the intended use and indications for use.

Indications for use

The software is intended to guide and assist the user (dental technician/dentist) in planning and design of orthodontic treatments and devices as listed below:

• templates for the positioning of orthodontic brackets,
• clear aligners,
• bite anti-bruxism,
• templates for the realization of total mobile prosthesis.
  

The software allows the user to:

• create 3D models;
• perform dental analysis and virtual setup;
• simulate the treatment plan;
• evaluate the treatment objectives by the comparison of teeth position before, during and at the end of treatment.
  

The device must be installed and used according to the specific instructions provided by Age Solutions in this manual.

Intended population

The software is intended to be used in adults subjects (>16years) who need orthodontic or restorative treatments which include:

• templates for the positioning of orthodontic brackets,
• clear aligners,
• bite anti-bruxism,
• templates for the realization of total mobile prosthesis.

Operating principles

The device Maestro 3D Dental Studio Expert can import digital 3D files from 3D scans and 2D images (as patients' photos).

Then the software analyzes, modifies the input files with the aim to:

• create 3D models (according to the orthodontics standard Parallel, Tweed, Ricketts, ABO);
• perform analysis of specific parameters and create related reports (PDF) of the case study;
• modify the geometry of the input files (e.g. changing the size, structure and position of teeth);
• create other three-dimensional geometries that match the input files geometry;
• create digital sequences of dental casts related to the same case study
  

in order to physically realize the piece designed by the software.

Input files can originate from an extraoral scanner (3D scans of dental impressions) or from the 3D intraoral scanner. These can be laser scanners or structured light scanners. Allowed formats for the input data (3D models) are ..STL, .PLY, .OBJ.

2D images must be in .bmp,.jpg, .png, .tga file format.

It is also possible to import .xml files only for 4D motion function, which allows to apply a list of animations to the model of the lower dental arch. It has the only purpose of visualization and it is not possible to perform measurements or analysis on models.

The software Maestro 3D Dental Studio Expert can not import DICOM files nor input images from CT or CBCT.

The software exports digital 3D files (output) in the following formats: .STL, .PLY, .OBJ, .ZIP-STL, .ZIP-PLY, .ZIP-OBJ.

Output files represent the inputs of other software that manipulate these data and then transfer them to machineries such as 3D printers and CNC machines (e.g. thermoforming machines), which physically realize the piece designed by the software.

Contraindications

Technical contraindications:

• PC hardware configuration, Minimum requirements
• What features must the input models have?

Medical Contraindications:

Orthodontic treatments including brackets, clear aligners or bite are not indicated in case of severe gum recession, periodontitis, chronic inflammation and, in general, where other dental diseases coexist. A basic dental health is a prerequisite for the applicability of the described treatments. Regarding the Denture Guide application, as it is intended for edentulous patients, no inflammation nor other gum pathological conditions should be present.

Warnings

The software Maestro 3D Dental Studio Expert does not provide by itself diagnosis or therapies, it is a tool to support dental professionals in performing orthodontic and restorative treatments through acquisition, processing and analysis of 3D images with the aim to create 3D models needed for the treatments.

Medical decisions cannot be based exclusively on data/analysis provided by the software. Diagnostic and therapeutic decisions are under the responsibility of the qualified personnel authorized for use of the software.
