Figure 4. (A) A bulky lesion of the inferior wall of the vestibule extensively invaded the superior lip; (B and C) Catheters were placed both along the “classical” subperichondral paths and perpendicular to them along the coronal main axis of the superior lip; (D and E) This allowed the target volume to be completely covered with a fully interstitial implant.
