Abstract

Aim: The aim of this case report is to present a case with overdenture attachment. Background: Loss of teeth in the mandibular arch leads to increased resorption of the alveolar bone resulting in instability of the mandibular ridge. The principles of preventive prosthodontics enable us to preserve the remaining natural teeth and use them as abutments for added retention, improved proprioception, and masticatory efficiency. Case description: The patient was evaluated clinically and radiographically and a tentative jaw relation was recorded. The patient following extraction presented with maxillary completely edentulous arch and mandibular arch with 33, 34, 43, and 44. The abutment teeth were prepared to receive a bar attachment on 33 and 43 and dome-shaped preparation to receive metal copings on 34 and 44. Final impressions were made using zinc oxide eugenol paste and addition silicone impression material for the maxillary and the mandibular arch, respectively. Following the fabrication of the attachments, the jaw relation was recorded. Teeth arrangement was assessed and dentures were processed. Conclusion: The patient was successfully rehabilitated with a maxillary conventional complete denture and an overdenture attachment Hader bar with 33 and 43 to improve the stability of the mandibular denture. Clinical significance: This technique of overdenture attachment with the Hader bar allowed splinting of the abutment teeth along with stress distribution subsequently benefiting the patient psychologically.
