Methods A splinted metal-ceramic crowns （from the upper right first molar to left molar） and a bar with stud attachments was done. A removable partial denture （RPD） containing the patrix portion of the attachment was then designed to restore the missing maxillary anterior teeth and alveolar ridge. Finally,, The facial prosthesis was joined to the denture utilizing two retentive metal posts on the superior aspect of the removable partial. Results A splinted metal-ceramic crowns （from the upper right frst molar to left molar） and a bar with stud attachments was done. A RPD containing the patrix portion of the attachment was then designed to restore the missing maxillary anterior teeth and alveolar ridge. Finally, The facial prosthesis was joined to the denture utilizing two retentive metal posts on the superior aspect of the removable partial. The prosthesis markedly improved the appearance of the patient and demonstrated good retention. Conclusion Using attachment in restoring rnaxillofacial defect may provide adequate retetion which lead to a sucessful treatment outcome.展开更多
