Abstract
Background: This study aims to evaluate the effect of the distance between the alveolar crest of a full-ceramic implant to the lowest point of the contact area of the crowns on the interdental papilla. Therefore, the authors proposed a new concept of linear measurements for the reproducible and metric evaluation of distances relevant for the assessment of hard and soft tissue changes around dental implants. Methods: A total of 216 sites were examined in 87 patients. In a radiographic and clinical evaluation, four relevant distances were evaluated. In the x-ray image, the tip of the papilla was marked with a radiodense mixture of tungsten powder and temporary cement. In a clinical photograph, the lowest point of the interdental contact zone of the crowns was visualized by a metallic interdental ligature. Results: Using the proposed measuring methodology, four different papilla-deficit situations around ceramic implants could be reproducibly distinguished. When the measurement from the bone crest at the implant was <= 5 mm, the papilla was completely present in 100% of cases. When this distance was 10 mm, the papilla was still present in 67% of the cases, without any cosmetically apparent deficit. Conclusions: A close relationship is observed between the distance from the contact point to the bone and the presence of the papilla. Using a combination of radiographically and clinically visible landmarks allows the reproducible measurement of these distances.
