Comparison of interdental papilla around single implants in the Tissue Level (TL) and Bone Level (BL) Implant: A clinical trial

The aim of this study is to evaluate the effect of bone level implants in comparison with tissue level implants on dental papilla dimensions in single tooth implants.

In the present clinical trial study, 50 patients, 24 women (48%) and 26 men (52%) were selected among patients who had requested for single implants in the posterior area of the jaws. The subjects were divided into two groups (n=25). The first group was treated by the bone level implant (Implantium , Dentium, Korea) and the latter was treated by the tissue level implant (Implantium, Dentium, Korea). None of the implants were loaded during this time period and only the Healing effect was measured. All implants underwent one-stage surgery (none submerge) and healing abutments were placed after implantation.The measurements of papilla height in both mesial and distal aspects of adjacent tooth were measured. Periodontal probe was used to measure from the top of papilla to the CEJ of adjacent tooth in tow time periods. Descriptive statistics were performed using tables and using Shapiro-Wilk, Chi-square, Mann-Whitney and independent t-tests.

The findings showed that interdental papilla in TL single implant performed better than BL implant in three months interval. This difference was statistically significant on mesial side but not on distal side. However, this difference was not clinically significant.

Comparing papilla dimensions in two types of implants revealed that papilla formations in TL implants were better than BL implants in three months period after surgery.
