Abstract
Statement of problem
Patient-reported outcomes represent an additional and often overlooked measure of
dental implant and bone augmentation treatment. Few implant studies have evaluated
patient-reported outcomes in those with systemic bone compromise.
Purpose
The purpose of this cohort study was to assess oral health-related quality of life
(OHRQoL) outcomes in postmenopausal women receiving dental implants with normal bone
density or mild osteopenia (“healthy” group; all DXA T-scores at femoral neck, total
hip, and L1-L4 spine>−2.0) versus moderate osteopenia or osteoporosis (“bone compromised”
group; any DXA T-score at femoral neck, total hip, or L1-L4 spine≤−2.0).
Material and methods
A total of 115 patients were recruited at the University of Connecticut School of
Dental Medicine as part of a standard of care, prospective, nonrandomized cohort study.
All participants received 1 of 3 bone augmentation procedures with implant placement.
At baseline and at various intervals after implant placement, OHRQoL was measured
by using the Oral Health Impact Profile-14 (OHIP-14) and surveys of patient expectations
and satisfaction. These measures were compared between healthy and bone compromised
groups (α=.05).
Results
For all OHRQoL measures across linear mixed effects models, no significant differences
were found between bone groups at baseline and at each time point after implant placement
(P>.05). Using the minimally important difference (MID) for OHIP-14, no definitive clinical
differences were found in patient outcomes between bone groups at all postimplant
time points (P>.05). From baseline to 24 months after implant placement, both healthy and bone compromised
groups exhibited significant improvements in OHIP-14 and patient expectations scores
(P<.05). While no within group differences were found in patient satisfaction scores,
the mean satisfaction score remained high over time in both groups.
Conclusions
Patient-reported outcomes as measured through OHIP-14, patient expectations, and patient
satisfaction surveys suggest similar postimplant OHRQoL improvement in healthy and
bone compromised individuals. OHRQoL improvements between bone groups were similar
both in continuity and in scope, with no evidence of statistically significant score
differences between groups at 24 months after implant placement across all measures
and with no definitive evidence of clinical differences as measured by OHIP-14 MID
comparisons across all timepoints.
