Restorative Emergence Profile for Single-Tooth Implants in Healthy Periodontal Patients: Clinical Guidelines and Decision-Making Strategies
Stephen J. Chu, DMD, MSD, CDT/Joseph Y. K. Kan, DDS, MS/Ernesto A. Lee, DMD/Guo-Hao Lin, DDS, MS/Leila Jahangiri, BDS, DMD, MMSC/Myron Nevins, DDS/Hom-Lay Wang, DDS, MS, PhD

The success of an esthetic implant is a combination of the surgical foundation, bone, and soft tissue health, and the subsequent restorative process composed of component selection, design, and implementation. Abutment design is an often-overlooked critical aspect of esthetic dental implant success. Dr Stephen J. Chu and at el present “Restorative Emergence Profile for Single-Tooth Implants in Healthy Periodontal Patients: Clinical Guidelines and Decision-Making Strategies,” which discusses how the proper restorative emergence profile design is essential to facilitate favorable esthetic outcomes and maintain peri-implant health. The aim of this article is to review the currently available evidence related to the design of subgingival (critical and subcritical) and supragingival contours of the implant restorative emergence profile (IREP) as well as provide a flowchart for decision-making in clinical practice. Abutment design is dependent on the three-dimensional spatial position of the implant relative to the hard and soft tissue complex, in additionto the location of the definitive restoration. Frequently, a convex critical contour is required on the facial aspect of a palatally or incisally positioned implant to support an adequate gingival-margin architecture. Conversely, if the implant is placed too far facially, then a flat or concave contour is recommended. In instances where soft tissue support is not needed, the subcritical area may be under-contoured to increase the thickness, height, and stability of the soft tissue cuff.
