- - Zirconia abutments are increasingly favored for their aesthetic benefits and suitability for patients with thin gingival tissue, although achieving reliable soft tissue attachment remains a challenge.
- - The text reviews recent advancements in zirconia surface treatments and designs that aid in soft tissue integration, providing guidelines and strategies for enhancing abutment surfaces and improving clinical outcomes.
Article Abstract
Stable soft tissue integration around the implant abutment attenuates pathogen penetration, protects underlying bone tissue, prevents peri-implantitis and is essential in maintaining long-term implant stability. The desire for "metal free" and "aesthetic restoration" has favored zirconia over titanium abutments, especially for implant restorations in the anterior region and for patients with thin gingival biotype. Soft tissue attachment to the zirconia abutment surface remains a challenge. A comprehensive review of advances in zirconia surface treatment (micro-design) and structural design (macro-design) affecting soft tissue attachment is presented and strategies and research directions are discussed. Soft tissue models for abutment research are described. Guidelines for development of zirconia abutment surfaces that promote soft tissue integration and evidence-based references to inform clinical choice of abutment structure and postoperative maintenance are presented.
