This is a retrospective cohort study that evaluates the survival (Outcome 1) of dental implant systems (external connection (Cohort 1) and internal connection (Cohort 2) and the effectiveness of maintaining crestal bone levels (Outcome 2), placed within United Kingdom Armed Forces personnel. The secondary objectives include: assessment of block bone grafting on outcome, assessment of restoration (bridge vs crown on outcome) and assessment of placement technique (immediate, early, delayed placement). Inclusion criteria: all military patients that received dental implants since 2014-2024. Exclusion criteria: military patients that have not received radiographic review or follow-up of the dental implant or who have left service or have a follow-up that is less than 12-months post placement of the dental implant..

Dental Implant Survival (presence of implant at point of review)
Null hypothesis: No difference in dental implant survival between the 2 cohorts (Platform-Matched vs Platform-Switched dental implant/ abutment interfaces). This is a binary outcome of either implant still present or implant absent at time of review.
Minimum time frame for inclusion is 12 months
Dental Implant Crestal Bone Levels
Minimum time frame for inclusion is 12 months
