It is often difficult to perform the tunnel technique for root coverage and soft tissue augmentation in the mandibular anterior region where there is shallow recession and thin soft tissue, particularly when accompanied by prominent roots and alveolar undercuts. The aim of this report is to present a papilla access technique that facilitates tunnel site preparation and graft placement in such sites. This surgical access method may also be applied to sites where there is moderate to severe recession of the mandibular central incisors, and extension of the tunnel to include both the lateral incisors and canines is desired for augmentation. The papillary access provides improved surgical access for both site preparation and graft placement with reduced risk of perforation or injury to thin tissue.
在下颌前部区域,当存在浅度牙龈退缩和薄软组织时,尤其是伴有牙根突出和牙槽骨倒凹时,进行用于牙根覆盖和软组织增量的隧道技术通常很困难。本报告的目的是介绍一种乳头入路技术,该技术有助于在这些部位进行隧道部位准备和移植物放置。这种手术入路方法也可应用于下颌中切牙有中度至重度退缩的部位,并且为了增量需要将隧道扩展至包括侧切牙和尖牙。乳头入路为部位准备和移植物放置提供了更好的手术入路,同时降低了穿孔或损伤薄组织的风险。
