The purpose of the present study was to compare two different surgical procedures, connective tissue graft and guided bone regeneration, when applied in conjunction with implant placement. Probing pocket depth and the recession depth were recorded at the implant site after crown placement (T₁) and at the 1-year follow-up (T₂), while the keratinized tissue height and the buccal mucosa thickness were recorded at three different time points: at the time of implant surgery (T₀), after crown placement, and at the 1-year follow-up. No statistically significant differences in peri-implant mucosa thickness, recession, or other periodontal parameters were recorded at adjacent teeth.
