MIS Ti-base abutment is a titanium base placed onto MIS dental implants to provide support for customized cement-retained or screw retained single or multiple-unit restorations.
It is used with a digitally designed mesostructure. MIS Ti-base and the mesostructure make up a two-piece abutment used in conjunction with MIS dental implants, to be placed in the upper or lower jaw arches, in order to restore masticatory function.
Narrow platform Ti-bases are indicated for use only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws.
MIS short implants are to be used only with straight abutments.
Mesostructures for use with the MIS Ti-base abutment are to be made from inCoris ZI, designed and manufactured using Sirona CEREC SW version 4.6.1 Software.
MIS Ti-base abutments are intended for use with the following MIS implants:
C1 conical connection implant system. V3 conical connection implant system. SEVEN internal hex implant system. M4 internal hex implant system and Lance+ internal hex implant system.
The subject MIS Ti-base abutments are endosseous dental implant abutments intended to be connected to MIS dental implants and used to support CAD/CAM customized cement-retained or screw retained single or multiple-unit restorations.
MIS Ti-base abutments consist of a titanium base and a prosthetic screw, both made of TI-6AI-4V ELI complying with ASTM F136. The prosthetic screw tightens the finished CAD/CAM abutment to the dental implant.
MIS Ti-base abutments are the bottom-half/base of a two-piece custom zirconia-titanium abutment consisting of a zirconium coping/mesostructure and a titanium base.
The top-half custom zirconia coping/mesostructure or crown is intended to be fabricated from Sirona inCoris ZI zirconium oxide ceramic block and designed and milled using Sirona chairside Dental CAD/CAM System, with software version: CEREC SW version 4.6.1. The mesostructure design will be subject to the Sirona system controls, such as: A maximum angulation of 20° and minimum wall thickness of 0.5mm. The InCoris Zi mesostructure is to be cemented to the subject MIS Ti-base abutments using PANAVIA F 2.0 dental cement in order to complete the two-piece, CAD/CAM abutment.
lt is not permitted to reduce the Ti-base's diameter, shorten the Ti-base or modify its implant-abutment connection and emergence profile in any way.
The subject pre-fabricated titanium base abutment is designed with interface compatibility to specific MIS dental implant systems. The subject MIS Ti-base abutments are MIS conical connection and internal hex connection Ti-base abutments, and their connection is compatible with MIS conical connection C1 and V3 implants, and MIS SEVEN, M4 and Lance+ internal hex implants, which are not subject to this submission and were previously cleared.
Here's a breakdown of the requested information based on the provided FDA 510(k) document for the MIS Ti-base Abutment.
Important Note: This document describes a dental abutment, not an AI/ML device. Therefore, many of the requested fields regarding AI/ML-specific study aspects (e.g., sample size for training set, number of experts for ground truth, MRMC study, standalone algorithm performance) are not applicable to this type of medical device submission. The FDA 510(k) process for a device like this focuses on demonstrating substantial equivalence to a legally marketed predicate device, primarily through non-clinical performance testing.
Device Name: MIS Ti-base Abutment
Regulation Number: 21 CFR 872.3630
Regulation Name: Endosseous Dental Implant Abutment
Regulatory Class: Class II
Product Code: NHA
1. Table of Acceptance Criteria and Reported Device Performance
For non-AI/ML medical devices like this, "acceptance criteria" are tied to demonstrating substantial equivalence to a predicate device, often through mechanical and material testing against established standards. The performance is assessed against these standards and comparative data from the predicate.
| Acceptance Criteria Category | Specific Acceptance Criterion | Reported Device Performance |
|---|---|---|
| Material Compatibility | Made of TI-6Al-4V ELI complying with ASTM F136. | The device is made of TI-6Al-4V ELI complying with ASTM F136. |
| Biocompatibility | Meet biocompatibility requirements for patient contact duration and type. | Biocompatibility testing was not required for the subject device. It is manufactured using identical methods, facility, and raw material as a previously cleared reference device (K163349) with the same patient contact. The mesostructure material (InCoris ZI) is also previously cleared (K181520). |
| Dynamic Fatigue | Withstand 2,000,000 cycles without failure at a substantially equivalent load to cited predicates, adhering to ISO 14801:2016. | The worst-case abutments (narrowest from narrow and standard platforms, with 20° mesostructure) withstood 2,000,000 cycles without failure at a substantially equivalent load to predicates. The standard platform worst case also supported wide platform abutments. The results support substantial equivalence. |
| Sterilization Efficacy | Validate steam sterilization parameters for both gravity displacement and pre-vacuum methods, according to ANSI/AAMI/ISO 17665-1:2006 and ANSI/AAMI/ISO 17665-2:2009. | Sterilization parameters were validated for both gravity displacement and pre-vacuum steam sterilization methods according to the specified ISO standards. |
| Software Verification & Validation | Demonstrate that the abutment design library prevents mesostructure component design outside of limitations and that established design limitations are locked. | Software verification and validation testing was provided for the abutment design library to demonstrate use with CEREC SW version 4.6.1. It demonstrated restrictions preventing design outside limitations and that design limitations were locked. |
| Mechanical Design Integrity | Not permitted to reduce Ti-base's diameter, shorten the Ti-base, or modify its implant-abutment connection or emergence profile. | This is a design specification, adherence to which is asserted by the manufacturer. The document doesn't detail performance testing specifically verifying "non-modification" in the field, but rather the manufacturer's control over the design. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set:
- For Fatigue Testing (ISO 14801:2016), samples were tested. While a specific number isn't explicitly stated on the provided pages, ISO 14801 typically requires a sufficient number of samples (often 5-10 per test group) to achieve statistically meaningful results for fatigue curves. The document refers to testing "worst case abutments" from both narrow and standard platforms.
- For Sterilization Testing, an unspecified number of representative samples would have been used for validation.
- For Software Verification & Validation, the "test set" would be various design scenarios and inputs used to confirm software functionality and adherence to design constraints. The specific "sample size" of test cases is not quantified here.
- Data Provenance: The studies were non-clinical performance tests conducted by MIS Implants Technologies (manufacturer). The location of testing is not specified, but the manufacturer (Dentsply Sirona / MIS Implants Technologies Ltd.) is located in the USA (York, Pennsylvania) and Israel, respectively. These are prospective tests performed specifically for this 510(k) submission.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts
- N/A (Not Applicable for this device type). Ground truth based on expert consensus is typically relevant for AI/ML diagnostic or prognostic devices. For a dental implant abutment, "ground truth" is established by adherence to engineering standards, material specifications, and mechanical performance limits. The "experts" involved would be engineers and quality control personnel responsible for developing and conducting the tests, interpreting standard requirements, and designing robust products. Their qualifications would be in relevant engineering, materials science, and quality assurance fields.
4. Adjudication Method for the Test Set
- N/A (Not Applicable for this device type). Adjudication methods like 2+1 or 3+1 are used in clinical studies, especially for AI/ML devices, where human readers (often physicians) independently evaluate medical images or data, and a tie-breaking or consensus process is needed. For mechanical and software performance testing, adjudication is based on objective measurements and established pass/fail criteria from international standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. This is not an AI/ML device, so an MRMC study comparing human reader performance with and without AI assistance was not conducted and is not relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- N/A. This is not an AI/ML algorithm. Its "performance" is mechanical and procedural, not algorithmic. The software component (CEREC SW) is for design and manufacturing, not for automatic diagnosis or interpretation.
7. The Type of Ground Truth Used
- For this device, the "ground truth" is established by:
- Engineering Standards: Adherence to established international voluntary consensus standards (e.g., ISO 14801:2016 for fatigue, ANSI/AAMI/ISO 17665 for sterilization).
- Material Specifications: Compliance with material standards (e.g., ASTM F136 for TI-6Al-4V ELI).
- Validated Design & Manufacturing Parameters: Verification that the CAD/CAM software maintains design limitations and that the manufacturing process yields correct physical properties.
- Predicate Device Performance: Comparative performance data against the legally marketed predicate devices serves as a benchmark for substantial equivalence.
8. The Sample Size for the Training Set
- N/A. This is not an AI/ML device, so there is no "training set." The development process relies on engineering design, material science, and established manufacturing practices, not machine learning.
9. How the Ground Truth for the Training Set was Established
- N/A. As there is no training set for an AI/ML model, this question is not applicable.

4. Device Description:
The subject MIS Ti-base abutments are endosseous dental implant abutments intended to be connected to MIS dental implants and used to support CAD/CAM customized cement-retained or screw retained single or multiple-unit restorations.
MIS Ti-base abutments consist of a titanium base and a prosthetic screw, both made of TI-6AI-4V ELI complying with ASTM F136. The prosthetic screw tightens the finished CAD/CAM abutment to the dental implant.
MIS Ti-base abutments are the bottom-half/base of a two-piece custom zirconia-titanium abutment consisting of a zirconium coping/mesostructure and a titanium base.
The top-half custom zirconia coping/mesostructure or crown is intended to be fabricated from Sirona inCoris ZI zirconium oxide ceramic block and designed and milled using Sirona chairside Dental CAD/CAM System, with software version: CEREC SW version 4.6.1. The mesostructure design will be subject to the Sirona system controls, such as: A maximum angulation of 20° and minimum wall thickness of 0.5mm. The InCoris Zi mesostructure is to be cemented to the subject MIS Ti-base abutments using PANAVIA F 2.0 dental cement in order to complete the two-piece, CAD/CAM abutment.
lt is not permitted to reduce the Ti-base's diameter, shorten the Ti-base or modify its implant-abutment connection and emergence profile in any way.
The subject pre-fabricated titanium base abutment is designed with interface compatibility to specific MIS dental implant systems. The subject MIS Ti-base abutments are MIS conical connection and internal hex connection Ti-base abutments, and their connection is compatible with MIS conical connection C1 and V3 implants, and MIS SEVEN, M4 and Lance+ internal hex implants, which are not subject to this submission and were previously cleared.
5. Indications for Use:
MIS Ti-base abutment is a titanium base placed onto MIS dental implants to provide support for customized cement-retained or screw retained single or multiple-unit restorations.
It is used with a digitally designed mesostructure. MIS Ti-base and the mesostructure make up a twopiece abutment used in conjunction with MIS dental implants, to be placed in the upper or lower jaw arches, in order to restore masticatory function.
Narrow platform Ti-bases are indicated for use only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws.
MIS short implants are to be used only with straight abutments.
Mesostructures for use with the MIS Ti-base abutment are to be made from inCoris ZI, designed and manufactured using Sirona CEREC SW version 4.6.1 Software.
MIS Ti-base abutments are intended for use with the following MIS implants:
C1 conical connection implant system, V3 conical connection implant system, SEVEN internal hex implant system, M4 internal hex implant system and Lance+ internal hex implant system.
{5}------------------------------------------------
6. Substantial Equivalence Discussion:
The subject MIS Ti-base abutments have the same intended use as the predicate Sirona Ti-bases cleared under K181520. They are intended for use in partially or fully edentulous mandibles and maxillae in support of single or multiple-unit cement retained restorations, in conjunction with endosseous dental implants to restore the function and aesthetics in the oral cavity.
The primary differences between the subject and predicate Ti-bases are minor geometrical differences. Both subject and predicate Ti-bases are indicated for use with an inCoris mesostructure designed and milled with Sirona Dental CAD/CAM System. The subject MIS Ti-base abutments are indicated for use with MIS dental implants while the predicate Ti-bases are indicated for use with different implant systems.
The principal of operation of the predicate and subject Ti-bases is the same. The digitally designed mesostructure is cemented to the Ti-base to make up a two-piece abutment. This two-piece abutment is attached to the implant by a prosthetic screw.
Table 1 provides a summary comparison of the indications for use and technological characteristics of the subject MIS Ti-base Abutments and the predicate Sirona TiBases cleared under K181520.
Table 1a. follows Table 1 and is provided as a summary comparison of the indications for use of the subject MIS Ti-base Abutments and the reference devices identified in Section 3 of this 510(k) Summary. The identified reference devices are used to document the subject MIS Ti-base Abutments' implant system compatibility. The indications for use comparison summary in Table 1a. demonstrates that relevant restrictions which are part of the cleared indications for use of the reference device implant systems (i.e., "MIS short implants are to be used only with straight abutments") are also included in the indications for use of the subject MIS Ti-Base Abutments. However, dental implant-specific indications in the cleared indications for use statements of the implant system reference devices are not applicable to the subject MIS Ti-base Abutments.
The K111421 reference device (Sirona Dental CAD/CAM System) is included due to the fact the fatigue test data originally submitted in K111421 was utilized as a comparator to the fatigue test results of the worst case constructs tested in support of the substantial equivalence of the subject MIS Ti-base Abutments in this premarket notification.

7. Non-Clinical Performance Data:
As part of demonstrating the substantial equivalence of MIS T-base abutments to the predicate devices (K181520) listed in this 510(k) submission, MIS Implants Technologies completed a number of non-clinical performance tests:
- . Biocompatibility - The subject device is manufactured using identical manufacturing methods, in the same manufacturing facility, and using the same raw material as the previously cleared reference device, K163349. The subject device has the same patient contact duration and type as the identified reference device. For these reasons, biocompatibility testing was not required to support substantial equivalence of the subject device. Consideration of biocompatibility requirements was made with reference to Guidance for Industry and Food and Drug Administration Staff: Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".
- . Biocompatibility (two-piece abutments mesostructure) — The final two-piece CAD/CAM abutments which are constructed utilizing the subject MIS Ti-base components are completed with CAM milled mesostructures composed of the InCoris ZI zirconium oxide material. The InCoris ZI meso material is cleared under K181520 and no modifications to the material are included in this premarket notification. Therefore, no new biocompatibility data relating to the InCoris ZI material was included in this submission in support of substantial equivalence.
- . Fatigue Testing – Mechanical testing of MIS Ti-base abutments in accordance to ISO 14801:2016 was conducted. The worst case abutments chosen for the tests were the narrowest abutments from both narrow and standard platforms, with a 20° mesostructure which is the maximum angulation possible in the Sirona Dental CAD/CAM System. The test articles were able to withstand 2,000,000 cycles without failure at a substantially equivalent load to the cited predicates. The fatigue test conducted on the standard platform worst case abutment supports the wide platform abutments as the SP is a worst case in terms of diameter and wall thickness, and both SP and WP abutments are made of the same material. The results of fatigue testing support substantial equivalence. Fatigue testing was conducted with reference to the Guidance for Industry and FDA Staff: Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments.
- . Sterilization Testing – MIS Ti-base abutments are supplied non-sterile and intended to be steam sterilized by the user. The steam sterilization parameters were validated according to ANSI/AAMI/ISO 17665-1:2006 and ANSI/AAMI/ISO 17665-2:2009 for two methods: gravity displacement steam sterilization and pre vacuum steam sterilization validation of the recommended sterilization process for the subject devices was conducted with reference to Guidance for Industry and FDA Staff: Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling.
- Reverse engineering analysis was not conducted in support of substantial equivalence due to the fact that the subject MIS Ti-base Abutments are proposed for compatibility only with MIS
{15}------------------------------------------------
dental implant systems. Dentsply Sirona is the sponsor/applicant of this premarket notification as the Owner/Operator of MIS Implants Technologies, Ltd.
- . Software verification and validation testing was provided for the subject abutment design library to demonstrate use with the "chairside" CAD/CAM software, CEREC SW version 4.6.1. Software verification and validation testing was conducted to demonstrate that the restrictions prevent design of the mesostructure component outside of design limitations. In addition, the encrypted abutment design library was validated to demonstrate that the established design limitations and specifications are locked and cannot be modified within the abutment design library.
8. Clinical Performance Data:
There was no human clinical data included in support of substantial equivalence. The non-clinical testing detailed in this submission support the substantial equivalence of the device.
9. Summary:
The comparison between the subject device and the predicate devices has shown that the indications for use, principles of operation, technological characteristics are the same. The results of nonclinical performance testing support a conclusion that the subject device is at least equivalent to the predicate devices with respect to dynamic fatigue performance.
10. Conclusion Regarding Substantial Equivalence:
The subject MIS Ti-base abutments have the same intended use, incorporate the same fundamental technology, and have similar indications for use as the predicate device (K181520). Test data to verify the performance of MIS Ti-base abutments has been provided including: dynamic fatigue and sterilization validation and the results of this testing, combined with the design and intended use comparison with the predicate device, support substantial equivalence.
