Prosthetic rehabilitation of mucormycosis patients using DMLS fabricated cast partial denture with semi‐precision attachments—A case series

Abstract

BackgroundThe rehabilitation of maxillectomy defects is a challenging endeavour that necessitates customizing the procedure for each patient. The successful treatment for these patients requires a combined conventional and contemporary treatment options. The high‐tech prosthodontic treatment option for these defects and distal extension cases are combining fixed and removable partial dentures with precision/semi‐precision attachments. It will enhance retention, stability, esthetics and functional ability of the prosthesis.MethodsThree post‐Covid Mucormycosis patients reported after localised debridement and partial maxillectomy for definitive rehabilitation. For partial Maxillectomy patients, DMLS designed cast partial denture along with semi‐precision attachments (Preci‐vertix and OT strategy Rhein For patient with localized defect, DMLS designed cast partial denture was planned. For both patients the defect area was kept as hollow cavity (Closed or Open), in order to reduce the weight of the prosthesis.Results and ConclusionThe prosthodontic rehabilitation of these patient can be a simple and economical treatment options and it improves the stomatognathic functions and quality of life of the patient. The major hurdles during rehabilitation are retention and stability as there is no basal seat and hard tissue support. Hence, we tried a combined conventional and digital techniques in order to provide prosthesis with precise fit and accuracy as well as reducing the treatment time and visits of the patients.
