Evaluation of peri-implant bone levels and soft tissue dimensions around zirconia implants—a three-year follow-up study

The aim of this study was to measure bone levels around zirconia implants during follow-up of up to 3 years. Additionally, the effect of clinical contact point positions on the papilla deficit was evaluated. Eighty-one patients with 105 zirconia implants were examined at the 3-year follow-up. Bone levels were measured on the date of implant placement and at 3 months, 1year, and 3 years thereafter. Distances between the first bone–implant contact and the contact point of the crowns and between the bone level at the adjacent tooth and the contact point of the crowns were assessed.
