Radiographical Evaluation of the Gap at the Implant‐Abutment Interface

Dental radiography is often used for detection of marginal gaps at the implant-abutment interface. The angulation of the X-ray beam may lead to inaccurate diagnosis in gap detection. The use of a paralleling device is indicated for evaluation of marginal accuracy. The geometry of the implant (internal or external hexagon) influences the gap evaluation.
