A Retrospective Real-world Evidence Study Assessing the Safety and Effectiveness of the Nobel Biocare N1 Concept System.

Standard medical and dental forms from all subjects (i.e., adults ≥18 years old in need of a dental implant) who have been treated for CS Tiger Ultra Implant TCC RP dental implant treatment at the participating Clinics will be reviewed and clinical data will be obtained, only upon the receipt of Ethical Committee's approval and upon subject's signature of the corresponding Informed Consent Form.

All raw study data will be de-identified and corresponding subject information recorded in the data accrual system (e-CRF Smart Trial). Information recorded by the researcher shall not identify the subject and no individually identifiable data elements shall be recorded. The researcher shall receive a link to log in to e CRF system. The researcher will be asked to create an account and every log-in attempt into the system shall be controlled by an unique code. Radiographic measurements of marginal bone level mesial and distal to the implant (at time of surgery, implant loading and 12-months follow-up post-loading) carried out according to the standard practice of the clinic will be collected for the assessment of the marginal bone levels changes. Data will be anonymized before the x-ray collection.

An independent radiologist shall be responsible for the evaluation of the radiographic data. The Sponsor shall send to the radiologist all corresponding radiographic files entitled by study code, clinic and patient number, implant position and implant characteristics (diameter and/or length - where available) together with an Excel sheet where the Radiologist can accurately track the corresponding bone level measurements.
