Prosthetic reconstruction in the cleft lip and palate patient with an extracoronal resilient attachment retained removable partial overdenture: case report.
There are still some difficulties in prosthetic reconstruction of cleft lip and palate patients with conventional prostheses or implant retained prostheses. The most common difficulties are insufficient alveolar bone quality and quantity, inadequate soft tissue, and abutment teeth. The patient we report on was a 23-year-old man with a clinical diagnosis of right incomplete cleft lip and palate combined with midface dysplasia. The maxillary six anterior teeth were reconstructed. The maxillary right central incisor and canine were used as abutments for an extracoronal resilient attachment (ERA) retained removable partial overdenture. The STERN ERA SYSTEM is a hinged resilient attachment with an ideal stress breaking characteristic, a good retentive function, and easy chairside replacement. The 2-year follow-up examination revealed an adequate esthetic appearance with good retention and stability of the prosthesis. A removable partial overdenture using the teeth adjacent to the cleft area as abutments with an adequate attachment design is an alternative method for prosthetic reconstruction of cleft lip and palate deformity.
