Intended Use

DentiqGuide Software is a stand-alone Windows-based software application to support the treatment planning for dental implantation. It is designed for qualified dental practitioners, including dentists and lab technicians. The software imports the medical image dataset of the patient in DICOM format from medical CT or dental CBCT scanners for pre-operative planning and simulation of dental placement. It is intended for use as pre-operative planning software for the placement of dental implant(s) based on imported CT image data, optionally aligned to an optical 3D surface scan. Virtual Crowns can be used for optimized implant positioning under the prosthetic aspect. The digital three dimensional model of a surgical guided surgery can be designed based on the approved implant position. This 3D data can be exported to manufacture a separate physical product. Indications of the dental implants do not change with guided surgery compared to conventional surgery. Use of the software requires that the necessary medical training in implantology and surgical dentistry.

Device Story

DentiqGuide is a stand-alone Windows-based software for dental implant treatment planning. It imports patient DICOM data from CT/CBCT scanners, optionally aligned with optical 3D surface scans. Practitioners use the software to manage patient data, perform panoramic screen creation, set neural tubes, manage virtual crowns, and plan implant positioning. The software enables the design of 3D surgical guides based on approved implant positions, which are then exported for external manufacturing. Used in clinical settings by dentists and lab technicians; the output serves as an adjunctive tool for surgical planning. It does not contact the patient. Clinical benefit includes optimized implant positioning and surgical guidance based on prosthetic requirements.

Clinical Evidence

Bench testing only. Performance verified via software verification and validation (code, module, integration, and dynamic testing). Accuracy tests conducted using phantoms to compare software measurements (length, angle, HU) against true values, and to verify surgical guide dimensions and implant library sizes against user inputs/real values. All tests met pass/fail criteria of <2% average and maximum absolute difference.

Technological Characteristics

Stand-alone Windows-based software. DICOM image input; 3D mesh output for manufacturing. Features include patient management, data matching, crown management, panoramic creation, neural tube setting, implant planning, and surgical guide design. Cloud interoperability. No patient contact. Non-life-sustaining.

Indications for Use

Indicated for dental practitioners (dentists, lab technicians) performing pre-operative planning and simulation for dental implant placement using patient CT/CBCT data. Requires medical training in implantology and surgical dentistry.

## 9. Predicate Device:

Implant Studio™ by 3Shape Medical A/S (K152078) (LLZ, 21 CFR 892.2050)

## 10. Substantial Equivalence:

The DentiqGuide described in this 510(k) has the same intended use and similar technical characteristics as Implant Studio™ (K152078) by 3Shape Medical A/S.

{5}------------------------------------------------

The subject device and the predicate device are substantially equivalent, having the same indications for use, the same principle of operation, and similar functionalities like operation software, computer platform, image format, image processing features, windowing, 3D image construction, image edit, measurements and manipulation.

Comparing to as Implant Studio™ 2015-1 (K152078), the differences are such that the predicate device supports its own format additionally and the subject device does not have the feature for edentulous treatment and subsequent design of gingiva supported guides. However, these differences do not raise questions of safety or effectiveness since the two features of the predicate devices are additional options.

Based on the results of software validation and performance tests and the information provided herein, we conclude that the proposed device is substantially equivalent to the predicate device.

## 11. Technological Characteristics:

DentigGuide is a software device that does not contact the patient, nor does it control any life sustaining devices. Results produced by the software's diagnostic, treatment planning and simulation tools are dependent on the interpretation of trained and licensed radiologists, clinicians and referring physicians as an adjunctive to standard radiology practices for diagnosis.

## 12. Performance Data:

SW verification and validation testing activities such as code review, module review, integration review, and dynamic tests were conducted to establish the performance, functionality and reliability characteristics of the subject device.

Also the following performance tests were conducted to verify the performance of the subject device and find out any limitations.

- Accuracy test for measurement made in the subject device from loaded CT datasets using phantom by comparing the true values of the phantom and the measured values (Length, Angle. HU) in the subject device. The P/F criteria was less than 2% average and maximum absolute difference.

- Accuracy test to demonstrate that the generated output surgical guide by the subject device matches the user input requirements (Guide thickness, Offset from teeth to guide, Offset from sleeve to guide). The P/F criteria was less than 2% average and maximum absolute difference.

- Accuracy test to verify the size of the implants (Diameter and Length) which the implant library of the subject device provides by comparing them to the real size values of the implant. The P/F criteria was less than 2% average and maximum absolute difference.

The testing results support that the subject device is substantially equivalence to the predicate device.

{6}------------------------------------------------

## 13. Conclusion:

The subject device and the predicate device are substantially equivalent in the areas of technical characteristics, general function, application, and intended use. The new device does not introduce a fundamentally new scientific technology. Therefore, it is our opinion that the DentiqGuide described in this submission is substantially equivalent to the predicate device.
