Background: There is a growing need to evaluate the esthetics of implant‐supported crowns and bridges. An important tool for such an evaluation is standardized assessment of the soft and hard peri‐implant tissue levels. Methods: A simple acrylic device has been developed for reliable and reproducible assessment of soft and hard periimplant tissues using standardized color slides and standardized dental x‐rays. With this device, changes in both the soft and hard tissues around implant‐supported crowns can be evaluated as a function of time. The reproducibility of the technique was tested on color slides as well as on dental x‐rays in a series of implant‐supported crowns and their neighboring teeth. Results: The reproducibility of this technique was excellent. The measuring errors for repeated measurements of the soft and hard tissues were 0.14 ± 0.02 mm and 0.13 ± 0.01 mm, respectively. Conclusions: The device is a reliable tool to assess changes in both soft and hard tissues around crowns and implants over time. Likewise, it is suggested that this technique also can be used to objectively assess soft and hard tissue changes around natural teeth with or without prosthetic restorations.
