Inclusion Criteria
1. Data relating to adult patients with an explanted dental implant (osseointegrated and non-osseointegrated) between January 1, 2005 and December 31, 2021.
2. Radiographic data available in the file.
3. Reason for explantation available.
Exclusion Criteria
1. Data relating to patients whose reason for explantation is unsure.
2. Incomplete data (radiographs unable to measure the entire implant or not usable due to exposure/distortion, etc.).
3. Implants placed for orthodontic reasons or temporary implants.
4. Document attesting to a consent refusal.

- Not specified
- Primary Outcome Measures
Name Time Method Radiographic residual bone levels (mesured as percentage of the implant length) at the moment of explantation
- Secondary Outcome Measures
Name Time Method Measured using patient records:<br>1. Implant position, demographic data (such as age) and life of the implant at the explantation.<br>2. Is implant loss associated with poor periodontal conditions (such as history or diagnosis of periodontitis, number of pockets, radiographic bone loss, bone loss/age ratio, scaling visits frequency)?<br>3. Is implant loss associated with poor prosthetic reconstructions (such as inadequate emergence angle, cantilever presence, number of implants, prosthetic misfit, type of antagonist)?<br>4. Is implant loss associated with medical conditions, drugs intake and/or tobacco consumption?<br>5. Is implant loss associated with any of other analyzed factors?<br>6. Tendency of the number of explantations in last 15 years<br>
