Gain of keratinised tissue
Augmentation of width of keratinised tissue around prosthetic restoration
Aim: Augmentation of the width of keratinised tissue around prosthetic restoration, avoiding the patient morbidity caused by autogenous soft-tissue grafts.
Conclusion: Mucograft® (prototype)* is as effective and predictable as connective tissue graft (CTG) to gain an adequate width of keratinised tissue. The 3D-matrix shows excellent handling properties and can be used successfully in an open healing situation, reducing significantly patient morbidity and surgery time compared to CTG.
Pre-operative image. Note the minimal amount of keratinised tissue around the premolar and molar sites.
Split-thickness flap elevated to prepare the surgical bed for the soft-tissue device.
Mucograft® (prototype)* is trimmed in dry state to the defect size.
The 3D-collagen matrix, Mucograft® (prototype)*, is sutured to the prepared surgical bed and left exposed for healing.
Healing of the soft tissue, 10 days after surgery before suture removal.
View immediately after suture removal. Note the rapid re-epithelialisation of the treated site.
Post-operative view after 1 month.
Situation after 3 months.
