Full title and description

ISO/TS 22911:2016 — Dentistry — Preclinical evaluation of dental implant systems — Animal test methods. This Technical Specification provides guidance on designing and conducting animal tests to assess the functional behaviour of dental implant systems using macroscopic and microscopic end‑points; it is intended for use only when risk analysis indicates that additional information obtainable only by animal testing is required.

Abstract

ISO/TS 22911:2016 describes animal test methods relevant to functional assessment of dental implant systems (macroscopic, radiographic and histological evaluation). It emphasises use only when justified by risk analysis and clarifies that the Technical Specification is aimed at qualitative evaluation of the implant–bone interface rather than providing mechanical strength data for implantable materials.

General information

• Status: Withdrawn (superseded/replaced in the ISO lifecycle).
• Publication date: July 2016 (Edition 2, published 2016-07).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.060.15 — Dental implants.
• Edition / version: Technical Specification, 2nd edition (2016).
• Number of pages: 7 pages (English/French available).

Scope

This Technical Specification covers animal test methods intended to provide additional preclinical information about the functional behaviour of dental implant systems where required by risk analysis. It addresses selection and number of test animals, animal welfare considerations, test specimen and control specimen preparation, surgical placement procedures, test periods, clinical and radiographic monitoring, extraction and histopathological preparation, and macroscopic/microscopic evaluation of implant–bone integration. It is not intended to measure basic mechanical strength of implantable materials.

Key topics and requirements

• Requirement to use animal testing only when justified by a documented risk analysis and when alternative methods are insufficient.
• Test protocol elements: definition of test and control specimens, surgical site preparation and implant placement procedures.
• Animal welfare and ethical requirements, including selection of appropriate species, welfare measures and minimisation of animal numbers consistent with scientific objectives.
• Defined test periods and monitoring: clinical, radiographic and macroscopic observations during and at the end of test periods.
• Methods for extraction of specimens, histological processing and microscopic evaluation of the implant–bone interface.
• Note that the specification provides qualitative assessment guidance (interface evaluation) rather than quantitative material strength testing.

Typical use and users

This Technical Specification is used by preclinical research teams, dental implant manufacturers, contract research organizations (CROs) performing animal studies, regulatory reviewers and standards committees involved in device evaluation. It supports preparation of preclinical dossiers where animal testing is necessary to characterise implant–tissue interactions prior to clinical application.

FAQ

Q: What is this standard?

A: ISO/TS 22911:2016 is an ISO Technical Specification titled "Dentistry — Preclinical evaluation of dental implant systems — Animal test methods" that provides guidance on animal-based preclinical tests for dental implant systems.

Q: What does it cover?

A: It covers design and conduct of animal studies to assess functional outcomes of dental implant systems (macroscopic, radiographic and histological evaluations), including test protocols, animal welfare, specimen preparation and evaluation methods; it is not intended for measuring material mechanical strength.

Q: Who typically uses it?

A: Preclinical researchers, implant manufacturers, CROs conducting animal studies, regulatory reviewers and standards developers involved in dental implant evaluation.

Q: Is it current or superseded?

A: ISO/TS 22911:2016 is shown in the ISO catalogue as Withdrawn. ISO’s lifecycle information and several national bodies indicate it has been superseded/related to later documents (for example ISO 7405:2018 is listed as a related/revising document). Users should consult the ISO catalogue or their national standards body for the presently applicable standard for preclinical/biocompatibility testing.

Q: Is it part of a series?

A: It is part of ISO/TC 106/SC 8 work on dental implants and sits in the family of dentistry standards addressing implant system vocabulary, test methods and biocompatibility; it replaces the 2005 edition of ISO/TS 22911 and is linked in the ISO lifecycle to related documents.

Q: What are the key keywords?

A: Key keywords are dental implants, preclinical evaluation, animal test methods, implant–bone interface, histopathology, radiographic evaluation, animal welfare.
