Intended Use

The drill is used to pre-drill into the maxilla or mandible to create an initial osteotomy for the later endosseous dental implant placement. The drills are used with a handpiece. CeraDrill is a ceramic drill for the dental implantology made of a modern high performance ceramic. The drills are intended to be used with a handpiece. The intended use for this device is to cut into the maxilla or mandible to create an osteotomy for endosseous dental implant placement.

Device Story

CeraDrill is a ceramic pilot drill used in dental implantology to create an initial osteotomy in the maxilla or mandible. The device is operated by a dentist using an electrical powered handpiece. It features a high-performance ceramic (ZrO2/Al2O3/Y2O3) construction with specific twist drill blade geometry and lasered depth markings for precise penetration control. Unlike metal drills, it is metal-free, biocompatible, and corrosion-resistant. The device provides high cutting efficiency and improved thermal safety compared to traditional steel burs. It is designed for repeated use, capable of being cleaned, disinfected, and sterilized for at least 10 cycles without significant loss of mechanical stability. The output is a prepared bone site ready for subsequent implant placement, facilitating positive osseointegration.

Clinical Evidence

No clinical data. Substantial equivalence is based on non-clinical performance testing, including physical and biological characterization, thermal safety analysis, and mechanical stability testing after repeated reprocessing cycles.

Technological Characteristics

Material: ZrO2/Al2O3/Y2O3 ceramic. Design: Twist drill with 2 or 3 cutting flutes; external irrigation. Dimensions: Various diameters and lengths. Energy: Powered by electrical handpiece. Biocompatibility: ISO 7405 compliant. Reprocessing: Sterilizable, validated for at least 10 cycles. Features: Lasered depth markings at 2 mm intervals.

Indications for Use

Indicated for patients requiring endosseous dental implants. Used to create an initial osteotomy in the maxilla or mandible for implant placement. Intended for use by dentists with a powered handpiece.

Regulatory Classification

Identification

A dental bur is a rotary cutting device made from carbon steel or tungsten carbide intended to cut hard structures in the mouth, such as teeth or bone. It is also intended to cut hard metals, plastics, porcelains, and similar materials intended for use in the fabrication of dental devices.

#### Description of the device:

CeraDrills within the new "CeraLine" is intended for use in implantology. These are made of high efficiency ceramics featuring an excellent cutting performance. The new CeraDrill offers the possibility of working without any metal, thus guaranteeing a biocompatible operation. Damages, as they occur in particular when disinfecting and cleaning steel burs with inappropriate agents, are now a thing of the past. The multifunctional ceramic drills are suited for initial preparation of the implant site axis and depth. The drills feature high initial sharpness and optimal cutting efficiency, thus achieving an effective material reduction. Due to their high efficiency toothing and the distinct tip-transversing blade, the drill has very good axial drilling properties for precise cutting without the need for prior use of a centering bur. The special twist drill blade geometry ensures smooth and precise operation. Moreover, the depth markings, which are lasered on to the working part in 2 mm intervals guarantee precise and safe control of the penetration depth.

The CeraDrill family is available in diverse dimensions and shapes for the individual preparation on the osteotomy. The following table shows the REF numbers, diameters, penetration depth, shank types, number of cutting flutes:

# Substantial equivalence determination

#### Non-clinical performance data:

The determination of substantial equivalence is based on several nonclinical tests, most of which are repeated in the body of this 510(k) submission.

This includes especially those tests showing the physical and biological characteristics. The test results can be summarised as follows:

- General technological equivalence between predicate and current device
- improved thermal safety -
- improved safety concerning the risk of inadequate bonding of the coating
- the assumable lower resistive ness against bending forces during operation is negligible, since those bending force being necessary for fracture would lead to unacceptable osteotomies (=misuse)

(Details on non-clinical test can be found in chapter 18 of this submission)

### Clinical performance data

The determination of substantial equivalence is not based on clinical data.

{7}------------------------------------------------

# Conclusion:

The main intention of the CeraDrill is to pre-drill into the maxilla or mandible to create an initial osteotomy for the later endosseous dental implant placement. As such the CeraDrill can be concluded to be substantial equivalent to the predicate device:

Amorphous Diamond Coated Drill, Nobel Biocare, K990846

The only technical difference is the material used: whereas the predicate device is made of steel and coated with amorphous diamond the CeraDril is made of a single material which is Zirconium oxide.

This technological difference leads to the following advantages of the CeraDrill device:

+ Metalfree preparation

+ positve Osteointgration

+ non allgergenic compared to CrNi Steal

There is no known disadvantage; the known difference in the bending strength of the materials does not have an impact in the intended use as identified in the chapter 18 of the submission.

The safety and performance data submitted in this file support a finding of substantial equivalence between the CeraDrill and the predicate device as specified above.

#### Any other information:
