To evaluate changes in oral health‐related quality of life (OHRQoL) following Corticobasal implant‐supported prostheses, using the Geriatric Oral Health Assessment Index (GOHAI).
Materials and Methods
This prospective, single‐arm pre‐/postobservational study included patients undergoing Corticobasal implant‐supported prosthetic rehabilitation at Narsinhbhai Patel Dental College and Hospital; no control or comparison group was included. Participants were recruited from January 2023 to August 2024. OHRQoL was assessed using the GOHAI at baseline and at the predefined 6‐month follow‐up visit. The final 6‐month assessment included in the analysis was completed in March 2025. Data were analyzed using SPSS Version 17.0. Paired t ‐tests were used for within‐participant pre‐/postcomparisons, and repeated‐measures analysis of variance (ANOVA) was used to evaluate changes over time and exploratory differences in change across participant and treatment subgroups.
Results
Of 116 enrolled participants, one was lost to follow‐up; 115 completed the 6‐month assessment and were included in the analysis (completion rate: 99.14%). Among them, 70.4% were female, 57.4% were aged ≥ 60 years, 78.3% were nonsmokers, and 57.4% had no reported medical history. The mean overall GOHAI score increased from 33.58 ± 7.36 at baseline to 50.84 ± 4.40 at 6 months, with a mean improvement of 17.26 points (95% CI: 15.77–18.75; p < 0.001; Cohen’s dz = 2.14). Significant improvements were observed in the functional, pain/discomfort, and psychological domains (all p < 0.001). Exploratory subgroup analyses suggested that the magnitude of GOHAI improvement may vary according to some participant and treatment characteristics; however, these findings were not adjusted for multiple comparisons and should be interpreted cautiously.
Conclusion
Within the limitations of this prospective, single‐center observational study, OHRQoL, as assessed by the GOHAI, improved significantly from baseline to 6 months following Corticobasal implant‐supported prosthetic rehabilitation in the investigated cohort. These findings indicate favorable patient‐reported outcomes following Corticobasal implant‐supported prosthetic rehabilitation and should be interpreted in the context of the uncontrolled study design and the absence of a comparison group for evaluating implant‐system‐specific effects. Further controlled longitudinal studies with larger and more diverse populations are warranted to confirm these findings and evaluate their longer‐term clinical relevance.
