Subsequently, conventional (control) and curved abutments (experimental) were placed in combination with a temporary restoration (left–right randomization). Plaster models of the healed sites were made to assess the stability of the soft tissues at baseline and after 6 weeks. To measure deseating force, a dontrix gauge was used while removing the abutments after 6 weeks.</p> </sec> <sec id="clr2335-sec-0003" sec-type="section"> <title>Results</title> <p>Although visually, differences in the transmucosal area were observed, the differences in marginal recession and in deseating force between abutments from the experimental and the control group never reached a statistically significant level. In general, some gain in soft tissue height was seen in both groups.
