BE ORIGINAL, BE PREDICTABLE. I only use Original Straumann abutments because non-original abutments may have adverse effects on clinical handling and introduce different failure risks. These adverse risks and effects are due to the changes in dimensions and materials that vary from the original articles. Imitation is NOT the sincerest form of flattery. Original Straumann abutments offer the most predictable and reliable results because they were machined to fit Original Straumann implants. Anything else is just unpredictable.
