Q

what are the symptoms of pericoronitis?

A

swelling of the operculum and/or other associated gingiva, redness, and extreme pain.
The tissue may be so swollen that it interferes with mastication.
Trismus (muscle spasm) may also occur.
The patient may have a fever.
Purulent exudate occurs in approximately one half of the patients with pericoronitis.

Q

An increased rate of bone growth and an increased amount of surface contact with bone:

A

Allows for better transfer of forces to bone.
Facilitates earlier loading, which is the placement of restorations on the implants.
Permits better success in areas with poor bone quality.
