After 3-6 months of implant placement usually it’s the the ideal timing for the clinician to uncover the dental implant(s).
A new piece of machined titanium is a attached to the implant housing by means of a screw. This connection is very crucial to keep the whole structure stable.
The crown can be cemented or more favorably screw retained ( an access hole maintained in the chewing surface of the crown which is covered later with a white filling and can be removed any time for maintenance or to clean excess cement between the crown and the abutment.
In terms of time intervals between implant placement and loading it with a crown, there is a paradigm shift toward immediate loading of multiple implants in the day of surgery especially when it crosses the arch and a less shift toward immediate loading over single implants as the load distribution can highly affect single implants and almost negligible when having 4 or more implants crossing the midline.
The only time we would take immediate loading as an option is when we have two sound clean teeth on both sides of the space in the upper front area that we do not by any mean want to touch and/or having a deep bite while a bonded crown can’t function well in the temporary phase after placement.
