Tunnel connective tissue graft
Tunnel connective tissue graft options
Tunnel connective tissue grafts are becoming more common and the steps and techniques may vary from clinician to clinician.
Pedicle tunnel connective tissue graft
The pedicle tunnel connective tissue graft is a nice trick for anterior soft tissue grafting. A vascularized interpositional periosteal (VIP) connective tissue graft and interpositional vascularized augmentation neogenesis (IVAN – Pohl JOI 2020) are other common names. This can be useful in Seibert Class III defects as seen in Ferreira JOI 2018.
Modified tunnel technique
Some tips for the modified tunnel technique
- Use a connective tissue graft of adequate thickness, which is 1-1.5mm.
- Temporarily bond the contacts points together to help with the suturing.
VISTA = Vertical Incision Subperiosteal Tunnel Access
Technique used for grafting anterior. Can be used for bone grafting pre-implant surgery or recession.
There is video of using SECTG and some alloderm? This would be one option for treating cervical lesions and/or recession in the anterior.
Could also use with sticky bone in anterior to bulk out facial which would be especially useful if doing immediate implant.
Some using PRF slugs to reduce secondary surgical site as well. Liang JOI 2023 shows a tunneling technique for GBR.
