Objectives: This study aimed to clinically assess and compare the width of peri-implant keratinized mucosa following the useof a readymade plastic stent with apically repositioned flap versus conventional apically repositioned flap with papillary sparing incisions during single-stage implant placement protocol. Materials and Methods. A total of 20 patients were enrolled in this study. In the test group, a prefabricated implant-retained stent was clipped on the healing abutment after implant surgery to reposition the keratinized tissue buccoapically. In the control group, simple interrupted sutures were applied instead of using a stent. After the surgical procedure, the width of the buccal keratinized mucosa was measured at the mesial, middle, and distal aspects of the healing abutment. &e change in the width of the buccal keratinized mucosa was assessed at 3 months and 6 months. Results. No statistically significant difference was found between the stent group and control group in 6 months’ interval where p 0.840, where both groups showed the same mean value of 4.70 ± 0.35 and 4.70 ± 0.63, respectively. &e percent of change in the width of KM was found to be higher in the stent group than in the control group with no statistical significance. Conclusion. &e use of a readymade plastic stent in combined full/partial- thickness apically repositioned flap shows to be effective in increasing the width of KM compared to the conventional technique. &is trial is registered with NCT03754894.
