Abstract
BACKGROUND: Oral health-related quality of life (OHRQoL) is a key indicator of success in full-mouth implant rehabilitation, particularly for patients with severe jawbone atrophy. This study evaluated OHRQoL improvements following immediate-loading, full-mouth implant-supported reconstructions. METHODS: A cross-sectional study was conducted on 208 patients who underwent full-mouth rehabilitation between 2017 and 2024. All patients had varying degrees of maxillary and/or mandibular atrophy. Maxillary rehabilitation included pterygoid, nasal, and zygomatic implants as needed, while mandibular cases utilized intermental foramen, linguo-mandibular, and bucco-mandibular implants, with nerve bypass techniques for severe atrophy. Immediate loading was performed in all cases. OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14) before treatment, five days post-treatment, and at 1, 2, and 4 years. RESULTS: Significant improvements in OHRQoL scores were observed post-treatment. The mean OHIP-14 score decreased from 9.21 ± 1.24 to 4.62 ± 1.06, reflecting improvements across all domains, including functional limitation, physical pain, psychological discomfort, physical discomfort, psychological disability, social disability, and handicap. Patients who typically require bone grafting or prolonged treatment periods benefited from immediate full-arch rehabilitation using QuickDent implants (QuickDent Korticale TPR, QuickDent Ossi, and QuickDent Korticale ZTP). CONCLUSION: Full-mouth implant rehabilitation with immediate loading significantly enhances OHRQoL, improving function, esthetics, and psychological well-being. This approach provides a predictable, efficient, and life-enhancing solution for patients with severe bone atrophy, even in cases previously considered unsuitable for conventional implant treatments.
