ABSTRACT
Objective: A severe Class II maxillomandibular relationship and increased overjet may present significant clinical challenges during fixed prosthetic rehabilitation, particularly in establishing anterior occlusal contacts, meeting esthetic demands, and selecting appropriate restorative materials. This case report aimed to present a comprehensive rehabilitation in which individualized material selection and prosthetic design strategies were used according to regional esthetic and functional requirements in the presence of complex occlusal conditions and different types of prosthetic support.
Case Presentation: A 79-year-old female patient with high esthetic expectations presented with a severe Class II maxillomandibular relationship and an overjet of approximately 7–8 mm. A full-arch implant-supported fixed prosthetic rehabilitation was planned in the mandible using seven implants. In the maxilla, natural teeth were present in combination with three implants in the right posterior region and two implants in the left posterior region. The existing vertical dimension of occlusion was maintained, with particular attention paid to avoiding any reduction in vertical dimension during rehabilitation. Due to the marked sagittal discrepancy and increased overjet, the limited occlusal contact of the maxillary anterior restorations with the opposing arch became an important determinant in material selection. Zirconia restorations were selected for the maxillary anterior region because of the patient’s high esthetic expectations and the relatively limited occlusal loading in this area. Metal-ceramic restorations were used in the mandibular arch and maxillary posterior regions to withstand functional loads and provide stable occlusal contacts. In the maxilla, tooth–implant connection was avoided because of the different biomechanical behavior of natural teeth and implants; therefore, implants were splinted to each other, while natural teeth were splinted separately to form independent prosthetic units. Following completion of the restorations, occlusal contacts were reorganized while maintaining the existing maxillomandibular relationship, and the patient’s esthetic and functional requirements were successfully addressed.
Conclusion: In complex full-mouth rehabilitations involving a severe Class II relationship and pronounced overjet, treatment planning should consider the existing maxillomandibular relationship, vertical dimension, regional distribution of occlusal loads, restorative material properties, and the biomechanical differences between natural teeth and implant supports. In this case, the combined use of zirconia and metal-ceramic restorations according to regional esthetic and functional demands, together with separate splinting of natural teeth and implants in the maxilla, provided an individualized prosthetic approach for managing complex occlusal conditions.
