Screwmentation is a popular technique that combines the advantage of cementable implant supported crowns (ease of contact and occlusal adjustment) and screw retained crowns (retrievability) and solves the problem of cement sepsis. This one went ideally so it's a good one to look at. This implant is at #3, and there's nothing distal to 3.
This one went really smoothly. This is a "steppy" procedure, but you end up with a retrievable crown that looks as good as a cementable and there's no worry about cement sepsis.
