gumkopiering

Gumkopiering is a term used in dental contexts to describe the duplication or replication of gingival tissue—gums—for the purpose of diagnostic modeling, treatment planning, and fabrication of dental prosthetics or implants. The term is primarily found in Swedish-language dental literature, and English-language sources typically describe the process with terms such as gingival impression, gingival replication, or soft-tissue replication.

In practice, gumkopiering encompasses both traditional impression techniques that capture gingival contours and modern digital methods that reconstruct gingival architecture from intraoral scans. Traditional methods may involve gingival retraction, impression syringes, elastomeric impression materials, and stone models to reproduce gingival morphology. Digital approaches use intraoral scanners, computer-aided design software, and sometimes 3D printing to create accurate models of the gums and surrounding tissues.

Applications include prosthodontics (crowns, bridges, full-arch dentures), implant dentistry (for implant-supported restorations where gingival contour affects emergence profile and esthetics), and orthodontics (for monitoring gingival changes during treatment). Achieving accurate gumkopiering requires attention to tissue management, color matching, and controlling tissue shrinkage or distortion during impression-taking and model fabrication.

Limitations and challenges include tissue mobility, inflammation, recession, and the natural variability of gingival architecture, which can affect replication accuracy. The field continues to evolve with digital workflows, aiming to improve fit, esthetics, and patient outcomes.
