Effect of cement line on radiographic detection accuracy of abutment-prosthesis misfit

Why it matters for dental
Prosthodontists and restorative dentists should know that cement-line thickness can significantly degrade the ability of peri-apical radiographs to detect abutment-prosthesis misfit, raising the risk of undetected marginal gaps and future biologic complications.
Key points
- Cement space obscures the radiographic line used to judge seating, making small vertical discrepancies harder to see on standard film or digital sensors.
- Study used controlled misfit levels (0–150 µm) and varying cement thicknesses to quantify loss of detection sensitivity.
- Findings imply that clinicians may need supplementary verification methods (e.g., tactile probing, CBCT, or intra-oral scanners) when cement-retained restorations are seated.
- Published ahead-of-print 4 Sep 2026 in The Journal of Prosthetic Dentistry—peer-reviewed data applicable to implant and tooth-supported fixed prostheses alike.
