The T1 Spray is intended to be used to clean and lubricate dental handpieces.

Device Story

Contra-angle handpieces (Endo 6:1, T1 LINE Endo 6 L, SIRONiTi Apex) hold/drive rotary burr instruments for endodontic procedures; used by trained dental personnel in clinics/labs. Devices connect to electric/air motors via ISO 3964 interface. SIRONiTi Apex includes torque limitation via gold-plated magnetic coupling to prevent file jamming via retro-rotation. T1 LINE Endo 6 L includes fiber optic illumination. T1 Spray is a lubricant for maintenance. Devices facilitate root canal measurement when used with apex locators. Output is mechanical rotation for canal preparation; clinical benefit includes improved access to preparation sites and controlled torque for NiTi file systems.

Clinical Evidence

Bench testing only. Compliance with ISO 14457 (handpieces/motors), ISO 10993 (biocompatibility/cytotoxicity/sensitization), and AAMI ANSI ST79 (sterilization) demonstrated. Literature review and medical professional appraisal performed.

#### 4 INTENDED USE

The contra-angle handpieces are used to hold and drive burr instruments for the purposes of rotary processing. The handpieces are intended for dental applications in endodontics and for root canal measurement and are used by trained dental personnel in dental practices and laboratories. The T1 Spray is intended to be used to clean and lubricate dental handpieces.

#### 5 DEVICE DESCRIPTION AND FUNCTION

# ENDO 6:1

Endo 6:1 is a contra-angle handpiece which is adapted to dental electric motors or dental air motors with the ISO 3964 interface. It is reusable and it does not have a fiber optic light system.

- Extra small head for better access to preparation site ●
- Depth measurement in conjunction with an apex locator

# T1 LINE ENDO 6 L

The T1 LINE ENDO 6 L contra-angle handpiece is equipped with a fiber optic light system. It is also adapted to dental electric motors or dental air motors with the ISO 3964 interface. It is reusable.

Features of T1 LINE ENDO 6 L:

- Extra small head for better access to preparation site
- Depth measurement in conjunction with an apex locator

### SIRONiTi APEX

The SIRONiTi APEX contra-angle handpiece is adapted to dental electric motors with the ISO 3964 interface. It is reusable.

SIRONiTi APEX is equipped with a torque limitation function. Once a set torque has been reached, a gold plated magnetic coupling prevents jamming of the file in the root canal by retro-rotation.

Features:

- . For NiTi files systems
- . No jamming of the file in the root canals
- Torque level can be easily set ●
- For electric motors ●
- Extra small head for better access to preparation site ●
- Depth measurement in conjunction with an apex locator

### T1 Spray

This is the lubricant used for maintenance and cleaning of the drive channels of the handpieces.

#### TECHNOLOGICAL CHARACTERISTICS SUMMARY 6

The overall design of the Sirona contra-angle handpieces is similar to the design of the predicate handpieces in that the predicate devices have similar indications for use and material composition as Sirona's contra-angle handpieces and include similar features, operating parameters, dimensions and functional requirements. The primary predicate device is the DENTAPORT ZX (K031204). The reference predicates are K090931, K103653, K042822, and K113674. Whereas Sirona's T1 LINE ENDO 6L has a light to illuminate the treatment area and is composed of mostly titanium, the predicate devices, Sirona's ENDO 6:1 and SIRONiTi Apex do not have any illumination light and are composed of Stainless Steel*. Morita's Dentaport ZX has a light function for polymerization. SIRONiTi Apex and ENDO 6:1 have the same head heights as the E3 Torque Control Motor and the head height of T1 LINE ENDO 6 L (12.2mm) is similar to the head height of DENTAPORT ZX (12.5mm). Sirona's device Indications for Use align with the indications for use of the primary

### predicate.

Sirona's devices are used by trained dental personnel and practices/laboratories for

- -Root canal treatment and
- -Root canal measurement

while Morita's DENTAPORT ZX and TCM Endo V are used for

- -Root canal treatment and
- -Root canal measurement

The other predicates have similar indications for use except the ENTRAN EB-300 which has no root canal (Apex) measurement function. Overall, the Sirona's instruments and the predicates have similar intended use. Finally, Sirona's accompanying T1 Spray has nearly identical indications for use as K113674.
