## Indications for Use

Checking fit of crowns, bridges, veneers, inlays and dentures.

## Device Story

GC Fit Checker Advanced is a silicone-based dental impression material used to identify high spots and pressure points on crowns, bridges, veneers, inlays, and dentures. The device consists of a base silicone paste and a catalyst silicone, delivered via tubes or a cartridge system. It combines technology from previous Fit Checker products with vinyl polyether silicone impression material to enhance hydrophilicity. The material is applied by a dental professional in a clinical setting to the prosthetic or oral site; it spreads uniformly and sets in the moist oral environment. Its translucency allows clinicians to visually examine the thickness of the material layer to assess prosthetic fit. By identifying areas of interference, the device assists the clinician in adjusting the restoration to achieve an optimal fit, reducing the need for repeated trial-and-error adjustments.

## Clinical Evidence

Bench testing only. Performance evaluated against ISO 4823 standards. Results: Detail reproduction 20μm (meets requirement); Elastic recovery 98.9–99.3% (meets requirement ≥96.5%); Strain in compression 4.2–4.5% (meets requirement 2.0–20%).

## Technological Characteristics

Silicone impression material (base and catalyst). Features improved hydrophilicity and translucency. Dimensions/form factor: tube or cartridge delivery. Testing performed per ISO 4823. No electronic components or software.

## Regulatory Identification

Impression material is a device composed of materials such as alginate or polysulfide intended to be placed on a preformed impression tray and used to reproduce the structure of a patient's teeth and gums. The device is intended to provide models for study and for production of restorative prosthetic devices, such as gold inlays and dentures.

- 3. Device description and Intended Use
GC Fit Checker Advanced is a silicone impression material intended to check fit by detecting the high spots and pressure points of crowns, bridges, veneers, inlays and dentures.

- 4. Components and Mode of Action
GC Fit Checker Advanced has two types of packaging/delivery systems in which the base silicone paste and the catalyst silicone are filled. One is in tubes and the other is a cartidge device, similar to silicone impression material.

Fit Checker Advanced was developed combining the technology of Fit Checker and vinyl polyether silicone impression material, EXA'Lence, to achieve higher hydrophilicity. Due to the improved hydrophilicity, the material easily and uniformly spreads and sets sharply under moist oral environment. The optimal translucency enables the users to examine the thickness with ease. This product reduces your stress during the fit checking process which is usually done repeatedly until a good fit is achieved.
