Purpose:

The objective of this study was to investigate the soft tissue response and periimplant crevicular fluid (PICF) content around platform-switched (PS) and platform-matched (PM) implants during early healing.

Materials and Methods:

Nonsmokers treatment planned to receive a single implant in 2 quadrants were recruited. Two-stage implant placement protocol with 1 PM and 1 PS implant was implemented. Periimplant probing depths (PDs), modified sulcus bleeding index, and plaque indices were recorded, and PICF was collected at 1, 2, 4, and 6 weeks after abutment connection.

Results:

PD readings were higher at week 1 than at week 6 for both groups (P= 0.0005). PD was statistically deeper in PM than in PS at week 1 (P= 0.03). There was a time-dependent decrease in total PICF volume for both groups. This decrease was statistically significant for PS (P= 0.0005), with no differences between the 2 groups …
