Esthetic and functional rehabilitation of occlusal collapse with a telescopic crown-retained removable partial denture

Abstract

Patient: The patient was a 49-year-old female with the chief complaint of multiple tooth loss, cold water-induced pain at the maxillary anterior teeth, and disturbance of esthetics and mastication. All teeth with gingival inflammation were untreated, causing occlusal collapse with esthetic and masticatory disturbance. Bite-raising was performed using a removable partial denture after initial periodontic and endodontic treatment. The provisional restoration was adjusted at the mandibular position with the increase of occlusal vertical dimension. The final prosthesis, which reproduced the form of the provisional restoration, was fabricated by a telescopic crown-retained removable partial denture.

Discussion: It is important to ensure that the treatment plan for occlusal reconstruction is minimally invasive and causes less lateral force on elongated teeth and inclined teeth. The use of a treatment denture made it possible to reflect the appropriate mandibular position in the final prosthesis.

Conclusion: It is suggested that masticatory function and esthetics were improved by a telescopic crown-retained removable partial denture with an appropriate occlusal vertical dimension and anterior guidance by bite-raising for this patient with occlusal collapse by unilateral infra-occlusion.
