It is well accepted that achieving an optimal interdental papilla between adjacent implants is esthetically challenging in implant dentistry. In general, there are 2 kinds of interproximal soft tissues that can be present between adjacent implants. One is the true anatomic interdental papilla and the other is a "papilla-like" tissue created by surgical intervention and prosthetic contouring of the tissues. The former is challenging to preserve, and the latter is difficult to create. Multiple techniques have been suggested to create and preserve this volume of interproximal soft tissue between adjacent implants. This article describes another technique to achieve a papilla-like tissue using an omega-shaped (Ω) incision design when implants are placed adjacent to each other in partially edentulous ridges. This incision design is intended to spare an area of soft tissue of approximately 4 mm × 4 mm between the anticipated positions of the adjacent implants. The area of soft tissue that is free from surgical insult later helps in the creation of a papilla-like tissue through interim restorations. Case reports of this technique on long-term partially edentulous ridges are described, with a follow-up period of 3 to 4 years. The technique is relatively simple and does not involve additional surgeries or additional time for healing.
在种植牙科中，在相邻种植体之间实现最佳的牙间乳头在美学上具有挑战性，这一点已得到广泛认可。一般来说，相邻种植体之间可能存在两种邻间软组织。一种是真正的解剖学牙间乳头，另一种是通过手术干预和组织的修复体轮廓塑造形成的“乳头样”组织。前者难以保留，后者难以创建。已经提出了多种技术来创建和保留相邻种植体之间的这种邻间软组织量。本文介绍了另一种技术，当种植体在部分无牙嵴中彼此相邻放置时，使用ω形（Ω）切口设计来实现乳头样组织。这种切口设计旨在在相邻种植体的预期位置之间留出一块约4毫米×4毫米的软组织区域。之后未受手术损伤的软组织区域有助于通过临时修复体创建乳头样组织。本文描述了该技术在长期部分无牙嵴上的病例报告，随访期为3至4年。该技术相对简单，不涉及额外的手术或额外的愈合时间。
