Oral Health-Related Quality of Life and Patient-Reported Outcomes After Implant Rehabilitation Using CAS Kit-Assisted Indirect Maxillary Sinus Augmentation: A Longitudinal Observational Study.

BACKGROUND

Partial edentulism in the posterior maxilla is frequently complicated by alveolar bone resorption and maxillary sinus pneumatization, limiting implant placement and negatively affecting oral health-related quality of life (OHRQoL). Minimally invasive sinus augmentation techniques, such as CAS KIT-assisted indirect sinus elevation, aim to reduce surgical morbidity; however, evidence regarding patient-reported outcomes and quality of life following such interventions remains limited.

OBJECTIVE

To evaluate oral health-related quality of life and patient-reported outcomes following implant rehabilitation using CAS KIT-assisted indirect maxillary sinus augmentation.

MATERIALS AND

METHODS

This longitudinal observational study included 34 patients who underwent CAS KIT-assisted transcrestal sinus augmentation with implant placement in the posterior maxilla. Postoperative recovery and satisfaction were assessed using the HRQOLquestionnaire over seven postoperative days. OHRQoL was evaluated using the OHIP-14 questionnaire at baseline and one month after prosthetic rehabilitation. Data were analyzed using repeated measures ANOVA with a significance level set at p < 0.05.

RESULTS

HRQOLscores showed a statistically significant improvement over the seven-day postoperative period (p < 0.001), with stabilization observed from Day 5 onward. OHIP-14 scores demonstrated a highly significant reduction from baseline to post-intervention assessment (p < 0.001), indicating marked improvement in OHRQoL across all participants.

CONCLUSION

CAS KIT-assisted indirect sinus augmentation followed by implant rehabilitation results in rapid postoperative recovery and significant improvement in patient-reported outcomes, supporting its role as a predictable and patient-centered treatment modality for posterior maxillary rehabilitation.
