Summary
Free gingival grafts and dermal matrix allografts were compared for increasing keratinized tissue around teeth. Both methods showed creeping attachment, with free gingival grafts yielding slightly more tissue coverage after 12 months.
Area of Science:
- Periodontology
- Oral surgery
- Tissue engineering
Background:
- Free autogenous grafts are a traditional method for increasing keratinized tissue around teeth with mucogingival defects.
- Creeping attachment is a known phenomenon studied with autogenous grafts.
- Biocompatible, acellular connective tissue materials offer an alternative to free gingival grafts for enhancing keratinization.
Observation:
- A patient with bilateral mucogingival defects in the canine and premolar regions was treated.
- One side received a free autogenous graft, while the contralateral side received a dermal matrix allograft.
- Creeping attachment was measured at 3 and 12 months post-surgery.
Findings:
- After 12 months, the free gingival graft achieved an average of 1.23 mm of creeping attachment.
- The dermal matrix allograft resulted in an average of 0.96 mm of creeping attachment after 12 months.
- Both graft types demonstrated creeping attachment, indicating successful tissue regeneration.
Implications:
- Free autogenous grafts may offer a slightly superior outcome in terms of creeping attachment compared to dermal matrix allografts.
- Dermal matrix allografts represent a viable alternative for increasing keratinized tissue, though potentially with less pronounced creeping attachment.
- Further research can explore long-term stability and patient-reported outcomes for both grafting materials.
