So, all things being equal for two dental implants, is it better to get a screw retained crown or a cemented crown (pick one that is better)?

Benefits-liabilities: Although both treatment options can be used predictably, they have their own advantages and disadvantages. When in doubt, let your doctor decide. Good luck!

All things equal: Personal preference is a screw retained crown (if you don't mind the access opening on the occlusal surface). If the implant is askew, then a custom post may be your only option. Short clinical crowns need screw retained.

Screw retained: Unless position dictates otherwise, screw-retained is preferred. Some reasons : one less connection, easier retrievability when needed, no worry of periimplantitis due to any residual cement at margins, one solid unit attached directly to implant. See Prosthodontist for more info, exam and options. Good Luck.

Screw Retained but: The real advantage of screw retained is the simplicity of fixing a problem if one occurs. With cementable crowns if the screw into the implant fails it is a very difficult problem to fix and often causes the restoration to be redone. Whereas with screw retained you can just tighten the screw.
