Abstract: Introduction: Edentulism remains a global oral health problem, compromising oral health and adversely affecting patient’s esthetics, chewing, speech, and quality of life. Appropriate treatment planning and meticulous implant and prosthetic selection are vital to treatment success. Evidence has documented higher survival rates for Corticobasal ® cement-retained implant-supported prosthetic designs. However, there is limited literature regarding screw-retained Corticobasal ® implant-supported prostheses utilizing multi-unit abutments with longitudinal follow-up. This report describes two cases of immediately loaded, screw-retained Corticobasal ® implant-supported prostheses with multi-unit abutments and a 24-month follow-up period. Case presentation: We present a multidisciplinary treatment approach for two cases presenting with complete and partial edentulism, rehabilitated with immediately loaded, screw-retained, fixed single-piece Corticobasal ® implant prostheses with multi-unit abutments and a 2-year follow-up period of 2 years. The reported cases showed 100% implant survival, along with healthy peri-implant soft tissues, improved speech, chewing ability, esthetics, self-esteem, and superior patient satisfaction. Clinical discussion: The use of screw-retained multi-unit abutments highlighted the advantages of retrievability, facilitating easy removal for maintenance, repair, or access for hygiene, especially in full-arch replacement cases, which often favor multi-unit abutment systems. This treatment approach demonstrated favorable peri-implant soft-tissue conditions and satisfactory prosthetic outcomes during the observation period, in line with the literature. Conclusion: Within the limitations of this two-patient case series, immediately loaded, screw-retained Corticobasal ® implant-supported prostheses utilizing multi-unit abutments demonstrated favorable clinical and radiographic outcomes over a 24-month follow-up period. This treatment approach provided predictable function, stable peri-implant health, and significant improvements in mastication, speech, appearance, and overall satisfaction. Larger prospective studies with longer follow-up are required to validate these findings.
