ABSTRACT
During implant placement, dehiscence defects can result in complications like mucosal recession and peri-implantitis. While guided bone regeneration (GBR) is a common approach to managing these defects, it is often complex and time-intensive. This case series evaluates an alternative method using a collagen matrix (Collagen Graft2®) applied to peri-implant dehiscence defects without GBR. Through three case series, this approach effectively preserves buccal contour, enhances gingival thickness, and supports bone regeneration, leading to favorable peri-implant conditions. These findings suggest that collagen matrix application is a viable and less invasive option for treating peri-implant dehiscence defects; however, further studies are required to validate these results.
