RESUMEN
The fracture of complete dentures constitutes a challenge and remains an unresolved problem. A midline fracture of single maxillary complete denture base especially in patients who have retained their natural mandibular teeth is an inevitable problem. Several factors have been attributed for the midline fracture including flexural fatigue resulting from cyclic deformation and those which exacerbate the deformation of the base or alter its stress. The present case report deals with oral rehabilitation of completely edentulous maxillary arch by incorporating metal denture base in place of the conventional Poly Methyl Methacrylate material to improve the longevity of the prosthetic replacement, at the same time prevent resorption of the underlying residual maxillary ridge.
RESUMEN
Functional stability and the preservation of remaining alveolar bone are primary, and often elusive, goals when restoring the partially edentulous arch. Conventional complete denture wearers experience a number of problem such as instability of the mandibular dentures, inability to masticate food. Overdenture increases the retention , improves support, preserve the alveolar bone by decreasing the rate of resorption and improves the masticatory efficiency resulting in improved quality of life and oral health. The teeth which are preserved play a vital role by improvement of crown root ratio, provide proprioception. Rehabilitation using over dentures is a widely accepted preventive approach due to its ease of fabrication and the successful prognosis. This clinical report describes a multidisciplinary approach for complete oral rehabilitation of a patient with two remaining natural teeth using precision attachment (ceka Preci‑Clix Radicular RC) for mandibular overdenture and conventional overdenture.
