Aim: To achieve a full-mouth rehabilitation of partial edentulousness using modified/extended precision attachments in a removable partial denture (RPD). Background: The success of a prosthodontic rehabilitation requires crucial balance between the modern and conventional treatment techniques. The attachment-retained partial dentures are one such type of prosthodontic treatment modality. Most traditional RPD are well designed but not used by the patient only because the individual does not prefer its appearance and the retentive quality. A modified extended precision attachment for eliminating metal display to upgrade the esthetics and to improve the retention of a long-span partial edentulous arch restored with a prosthodontic rehabilitation is described in this article. Case description: A 58-year-old male patient was referred to the Department of Prosthodontics for the replacement of missing teeth. On clinical examinations, it was diagnosed Kennedy's class I in the maxillary arch and class II in the mandibular arch with a reduced vertical dimension of occlusion. Precision attachment-retained partial dentures were planned in the maxillary and the mandibular arch. Conclusion: The success of the RPD depends on the retentive components and the underlying residual alveolar ridge. This case report highlights the esthetic outcome and improved retention in the maxillary and mandibular partial denture using precision attachments. Clinical significance: The treatment plan explained satisfactorily restores the esthetics, masticatory function, and improves the retention of the prosthesis by using precision attachment.
