Mandibular Bar Overdenture

Dr. Larson asks:

I have just inherited a new patient with a mandibular bar overdenture supported by 2 dental implants in the #22, 27 areas. The bar is slightly curved so that the 2 Hader clips are each slightly canted to the right and left.

I
think the arc of rotation of the overdenture is limited because these
clips
are not parallel and are not perpendicular to the midsagittal plane of
the
overdenture. The dental implants are 15 years old and the bone level is down
to
the third thread.

Several weeks ago the patient reported that she had
pain,
swelling and drainage around the dental implants, but is asymptomatic now. The
pocket health now is comparable to a healthy dental implant. In terms of
prognosis
or intervention, should I do anything different? Thanks for any comments and suggestions.
