Modified IVAN Technique: Long-Term Follow-Up of 20 Cases Over 2 to 11 Years

Summary:
When natural teeth fail, frequently there is a loss of hard and soft tissue. This may complicate subsequent dental implant placement by
creating insufficient bone to house the implant. This also occurs when the tooth has been missing for an extended period, especially in the
premaxilla, where the bone is less dense and often lacks sufficient volume of facial bone. Site reconstruction to accommodate implant
placement often requires both hard and soft tissue augmentation. The modified interpositional vascularized augmentation neogenesis
(mIVAN) technique achieves the desired treatment goals in both delayed and immediate placement scenarios. The technique will be
discussed as well as the long-term follow-up on 20 cases.
