Summary

This study tests whether a collagen patch made from pig tissue can help improve the gum tissue around dental implants in 20 adults aged 25-50 with thin gums. The patch is placed during implant surgery to see if it helps the gums heal better and stay healthy. Researchers will check healing, pain, and implant stability over 3 months.
