Tru abutment, no issues so far wit any of their ti bases come in 3.5mm and 5.5mm heights. Also Glidewell direct sell then in a 4.5mm and 6mm heights but in the library you can make a 3mm and knock the 4.5mm down to 3mm.
Andrew - TRU is not FDA approved on over 300 of their products. All of their ti bases are NOT FDA approved, nor any of their angled solutions, LOC solutions, multiunit solutions. If this matters to you then you should read the 510K documents since this will tell what is and what is not FDA approved.
