Intended Use
WINSIX Implant System is indicated for single or multiple tooth replacement, or for use in terminal intermediate edentulous sites in the mandible and/or the maxilla, and for totally edentulous arches. The system is designed to be surgically inserted in the bone structure of the mouth in order to replace missing teeth. It is intended for immediate loading when good primary stability is achieved and with appropriate occlusal loading.
Device Description
The family of WINSIX Implant System is intended for the treatment of oral endosteal implantation in the upper and lower jaw and for the functional and esthetic oral rehabilitation of edentulous and partially dentate patients. The family of WINSIX Implant Systems can also be used for immediate or early load implantation following extraction or loss of natural teeth. Implants can be placed with immediate function on single tooth and/or appropriate occlusal loading to restore chewing function. The prosthetic restorations used are single crowns, bridges and partial or full dentures, which are connected to the implants by the corresponding elements (abutments). The family of WINSIX Implant System includes the following devices: Fixtures and Abutments. The fixtures are the endosseous dental implantable devices produced in commercially pure titanium (grade 4), available in following models: K Model, KT Model, Conical Model, TTi Model with various diameters and lengths in order to meet diverse anatomical requirements. They are single use devices, supplied sterile and cannot be re-sterilised. The abutments give at the physician a complete prosthetic solutions in order to use the WINSIX implant system as intended. They have been divided in followings main groups: COVER SCREWS, HEALING SREWS, and ABUTMENTS (straight, angulated, millable, and flat shift).
More Information

Not Found

No
The document describes a standard dental implant system and does not mention any AI or ML components or functionalities.

Yes
The device is designed to be surgically inserted into the bone structure of the mouth to replace missing teeth and restore chewing function, which addresses a medical condition or improves a health outcome.

No

This device is a dental implant system designed to replace missing teeth and restore oral function, not to diagnose medical conditions.

No

The device description explicitly states that the WINSIX Implant System includes physical components such as "Fixtures and Abutments" made of commercially pure titanium, which are surgically inserted into bone. This indicates it is a hardware medical device, not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "single or multiple tooth replacement, or for use in terminal intermediate edentulous sites in the mandible and/or the maxilla, and for totally edentulous arches." It is designed to be "surgically inserted in the bone structure of the mouth in order to replace missing teeth." This describes a surgical implant for structural replacement, not a test performed on samples taken from the body to diagnose a condition.
  • Device Description: The description details the physical components of the implant system (fixtures and abutments) and their materials (commercially pure titanium). It describes their function in supporting prosthetic restorations. This aligns with a medical device for surgical implantation, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information about a patient's health status.

In summary, the WINSIX Implant System is a surgical dental implant system, which falls under the category of medical devices, not In Vitro Diagnostics.

The abutments give at the physician a complete prosthetic solutions in order to use the WINSIX implant system as intended. They have been divided in followings main groups:

  • COVER SCREWS are used for the restorative phase after implantation .
  • HEALING SREWS are used to cover the fixtures and to model the mucosa during her healing
  • ABUTMENTS are used for creation of screwed temporary or fixed elements. They have different features to allow the physician to adapt to the different anatomical situation. In detail:
    • The straight abutments are used for the construction of the fixed prosthesis when the implant axis are parallel in relation to the prosthetic axis
    • The angulated abutments with an anqulation of 15°,17°,20°,25° and 30° are used for the creation of fixed or screwed prostheses in the case of disparallelism between implant axis and prosthetic axis.
    • The millable abutments can be personalised thanks to the precision of the industrially manufactured connection and the possibility to shape of the abutment through hand milling.
    • The flat shift abutments are used to create a screw retained prosthesis, to increase the gingival height, in case of soft tissue thickness over 2 mm. In this case, the Flat shift abutment could be fixed to the fixture and then the flat shift cylindrical direct abutment can be fixed over the flat shift abutment. The flat shift retentive direct flared abutment is used for impression taking. The Flat shift abutments can be used only with internal hexagon fixtures
      According to the results of fatique testing maximum recommended abutment anqulation is 30°

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

BIOCOMPATIBILITY

  • Citotoxicity
  • Intracutaneous reactivity
    These tests were performed on abutments to evaluate the impact of the process of coloration.
    The results of the reports listed above show that the WINSIX abutments are:
  • Not Cytotoxic
  • Satisfying the requirements for intracutaneous reactivity test

SURFACE VALIDATION TESTS
Surface treatment is performed on implants through a MRS -Micro Rough Surface (sandblasted and acid-etched) treatment or with FCC – Full Contact Covering (superficial chemical treatment. A specific study has been done on each surface treatment, as summarized below:
MRS - The following assays were performed:
XPS analyses providing the qualitative and quantitative composition of the Micro Rough Surface coming in contact with the bone tissue
SEM analyses providing either qualitative chemical information of the implant's Micro Rough surface or the evidence of the effectiveness of metallic material decontamination protocol.
Cytotoxicity test on human osteoblastic cells (Saos-2) in contact with WINSIX implant with MRS. -
The results demonstrate that the chemical composition of the micro-rough surface is exactly the same as the predicate device. The SEM analyses quarantee the total absence of accumulations, residuals and stains. The cytotoxicity test points out that the Micro-rough surface is not cytotoxic. Overall, such results demonstrate equivalent performance and chemical characteristics as the predicate devices.

FCC – The following assays were performed:
XPS analyses providing the qualitative and quantitative composition of the Full Contact - Covering surface.
SEM analyses providing either qualitative chemical information of the FCC surface or the evidence of the effectiveness of metallic material decontamination protocol.
Cytotoxicity test on mouse connective tissue fibroblasts (L-929) in contact with the FCC treated fixtures of the WINSIX implants.
The results demonstrate that FCC surfaces have the typical composition of the Ti and thus they may be found substantial equivalent to the predicate device. The SEM analyses quarantee the total absence of accumulations, residuals and stains. Finally the cytotoxicity test points out that the FCC surfaces are not cytotoxic. Overall, such results support technical and performance features of the FCC WINSIX Implants.

MECHANICAL TESTS
The Mechanical test were performed in compliance with "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" and "ISO 14801: 2007 - Dynamic fatique test for endosseous dental implants" and demonstrated that the worst case chosen is able to resist to 5.000.000 cycles.
