The plug is sutured and then will stay there for about 5-10 days and is resorbed over time through the enzymes in the saliva and blood. After 4 months time, we will see a nice healed up socket with new bone which as grown underneath.

Clutter equals stress. Remove the clutter, open the room, let the patient “own” their dental chair space and integrate the technology.

How to identify the delivery location in a treatment room?
A standardized method to associate the location for the various names is to use the clock diagram, which provides a handy reference for describing the positioning of instrument access by the Doctor and Assistant. The patient’s head is at the 12 O’clock position while the patient’s feet would be indicated at the 6 O’clock position. For example, a right handed dentist could sit at the 11 O’ clock position and retrieve the instruments from their front side at the 9 to 10 O’ clock position while the assistant sits at the 3 O’ clock position.
Where should an assistant's instrument be located?
Ideally, Assistant’s instruments should be located in the rear of the room and not off the side of the chair. This way they are facing the assistant and are easy to access. Efficiency in modern dental treatment rooms require the assistant to be an integral part of the team, making ergonomics and accessibility to instrumentation crucial. Although assistant’s instruments can be post-mounted off of the chair, it is not recommended due to the poor ergonomics and inefficient access for the assistant. This should only be considered if the room dimensions do not allow rear delivery.
