Summary
Optimizing implant abutment height is crucial for dental restoration success. A minimum of 2 mm for transmucosal and transgingival dimensions is recommended to prevent complications and ensure predictable outcomes.
Area of Science:
- Dental implantology and prosthodontics
- Biomaterials and biomechanics
- Computer-aided design/computer-aided manufacturing (CAD/CAM) and generative design
Background:
- Implant abutments are vital for functional and aesthetic success in implant-supported restorations.
- CAD/CAM technologies have transformed dental implantology.
- Generative design offers a novel approach to optimizing implant abutment configurations.
Purpose of the Study:
- To review existing literature on implant abutment dimensions.
- To identify critical parameters for generative design of hybrid implant abutments.
- To establish optimal transmucosal and transgingival heights for predictable outcomes.
Main Methods:
- Bibliographic search of PubMed and Scopus databases up to July 1, 2025.
- Inclusion of 13 studies investigating transmucosal and prosthodontic height of implant abutments.
- Analysis of selected studies to determine key dimensional parameters.
Main Results:
- Transmucosal and prosthodontic height significantly impact complication reduction.
- Optimal transmucosal and transgingival heights are essential for biological and mechanical predictability.
- A minimum of 2 mm for both dimensions is recommended.
Conclusions:
- Optimizing transmucosal and transgingival heights of implant abutments is critical.
- Establishing these dimensions at a minimum of 2 mm promotes predictable biological and mechanical outcomes.
- These parameters will inform the generative design process for hybrid implant abutments.
