Use of BoneTrust® Mini and Mini+ Implants is not to exceed one hundred and eighty (180) days.
BoneTrust® Mini Esthetic abutments and BoneTrust® Mini Crown Base Abutments are intended for use with BoneTrust® Mini / Mini+ Dental Implants to provisional prosthetic reconstructions during the healing phase of permanent endosseous dental implants. Use of BoneTrust® Mini Esthetic abutments and BoneTrust® Mini Crown Base Abutments is not to exceed one hundred and eighty (180) days.
BoneTrust® Mini Ball Attachments are intended to be used with BoneTrust® Mini / Mini+ Dental Implants to support and/or retain provisional removable dental prostheses during the healing phase of permanent endosseous dental implants. Use of BoneTrust® Ball Attachments is not to exceed one hundred and eighty (180) days.
The BoneTrust® Mini Implant System is a two-piece dental implant system including various sizes of threaded root-form dental implants and abutments to provide temporary support of prosthetic restorations in edentulous or partially edentulous patients during the healing phase of permanent endosseous dental implant(s). The maximum duration of intraoral use of all members of the BoneTrust® Mini Implant System is 180 days.
The provided text describes a 510(k) premarket notification for the BoneTrust® Mini Implant System. This submission focuses on demonstrating substantial equivalence to previously cleared predicate devices, rather than proving a new device meets specific performance acceptance criteria through the types of studies typically conducted for novel AI/ML-driven medical devices.
Therefore, the requested information about acceptance criteria tables, sample sizes for test sets, expert ground truth, adjudication methods, MRMC studies, standalone performance, training sets, and ground truth establishment is not present in this document. This document primarily relies on a comparative analysis of:
-
Indications for Use: The BoneTrust® Mini Implant System's intended use is compared to that of primary and reference predicate devices (EM Provisional, Sterngold 2.2mm Angled Micro ERA Dental Implant System, BoneTrust® Implant Systems, MIS LOCKIT Abutments System, Nobel Biocare AB, OSSTEM Implant Co. Ltd.). The conclusion is that the indications are "Similar to primary predicate device" or "Substantially Equivalent." The additional limitation of implant duration (max 180 days) is noted as not changing the intended use.
-
Technological Characteristics: Detailed comparisons are made regarding:
- Implant Material: Titanium Grade 4 ASTM F67, identical to reference device K182313.
- Implant Type and Design: Screw-type, straight body/tapered body, self-tapping, with thread, two-piece design. Largely identical or similar to predicate/reference devices.
- Implant-Abutment Connection: External Torx Implant/Abutment fixture. Differences from some predicates (one-piece design or different connection types) are stated not to raise concerns regarding safety and effectiveness.
- Implant Dimensions: The proposed device's sizes (diameters and lengths) are stated to be "within range of primary predicate device."
- Surface Treatment: Machined / Microstructured blasted etched surface passivated, stated as identical to K191751 and K182313.
- Sterilization: Beta Radiation, identical to K182313.
- Abutment Material, Surface, Size, Connection, Angulation, and Sterility: Comparisons are made to various predicate/reference abutments, with conclusions of "Identical" or minor differences not raising safety/effectiveness concerns.
- Ball Attachment Material, Surface, Size, Connection, Angulation, and Sterility: Similar comparisons are made, concluding "Identical" or differences not impacting safety/effectiveness.
-
Non-Clinical Testing Summary:
- Clinical Studies: None were performed.
- Biocompatibility: Relied on previous clearance of BoneTrust® Implant System (K182313) due to identical manufacturing process and materials. Periodic bacterial endotoxin testing (USP ) is performed, with historical data showing acceptable levels.
- Fatigue Testing: Not deemed necessary as per FDA Guidance Document for Class II Special Controls, because the system does not contain angulated abutments.
- Sterilization: Beta-radiation sterilized (SAL 10⁻⁶) according to ISO 11137-1:2006 and 11137-2:2013. Efficacy reliant on K182313 due to identical process. Unsterile prosthetic components are intended for end-user sterilization, with methods identical to K182313.
- Shelf Life: 5 years, reliant on K182313 due to identical packaging system.
- Implant Surface Analysis: Energy Dispersive X-ray Spectroscopy (EDX) and SEM analysis were conducted, and results support substantial equivalence to legally marketed predicate devices.
In summary, there is no study described in this document that proves the device meets specific acceptance criteria in the manner requested, because the submission focuses on demonstrating substantial equivalence to existing devices through comparative analysis and non-clinical testing rather than de novo clinical or performance studies with defined acceptance criteria for a novel AI/ML device.
§ 872.3640 Endosseous dental implant.
(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
