Dental implant and bone augmentation treatment in bone-compromised patients: Oral health-related quality of life outcomes

Published:February 18, 2023DOI:


      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.


      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).


      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.


      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.
