SAC Classification - Risk and complexity assessment
Identification of the potential difficulty, degree of complexity and risk involved in implant related treatment for a given clinical situation is key to predictable, long-term stable outcomes.
The ITI has formalized an evidence-based system of classification for dental implant procedures to support clinicians at every level of expertise and experience.
The fully revised 2nd Edition of the SAC Classification in Implant Dentistry has been updated to ensure consistency with contemporary implant practice. It provides an evidence-based, objective framework for the assessment of the potential difficulty, complexity and risk of an implant related treatment for a given clinical situation and serves as a guide for clinicians in both patient selection and treatment planning.

Frequently asked questions
Frequently asked questions
What is the SAC Classification?
SAC stands for S(traightforward), A(dvanced) and C(omplex). The SAC framework was developed by the ITI to help practitioners assess the risks and complexity of clinical cases by providing normative classification guidelines based on scientific high-level evidence.
What is meant by “normative” classification?
No classification can adequately address cases or outcomes that deviate significantly from the norm. In this context, "normative" relates to the classification that conforms to the norm, or standard, for a given clinical situation in implant dentistry and thus to the most likely classification of a case based on contextual assumptions (e.g. patients' medical conditions are not compromised or are appropriately addressed, the clinician and the implant team are adequately skilled, recommended protocols are followed etc.)
What happens to the case information I submit for assessment?
None of the data you enter in our system to classify your cases is permanently stored if you make a standalone case assessment. If you use the SAC Assessment Tool as part of the Case Cloud, the system will automatically add the information you provide to your case documentation.
Is it possible to carry out combined Surgical/Prosthodontic assessments?
The SAC framework as established in the 2009 Quintessence publication looks at surgical and prosthodontic case assessments separately. It is not currently possible to make combined assessments.
What is the impact of the “Additional Complexity and Risk” section of the assessment?
Although the modifier values used to determine the additional complexity and risk do not have a direct impact on the basic normative case classification, some of them can have a considerable influence on the overall demands and risks of a case. If the system indicates that there is an elevated risk based on the combined additional modifier values you have entered, you need to factor this into the overall interpretation of the assessment result.
Can I generate a report for the assessments I carry out with the tool?
You can generate a PDF report of your case assessments at the end of the assessment process when the final case classification is displayed. Valid ITI membership is required to make use of this feature. Please log in before starting your assessment.
