Multidisciplinary rehabilitation of eosinophilic granuloma with bone graft surgery and a modified implant‐supported hybrid prosthesis: A case report with a 6‐year follow‐up

Abstract

Eosinophilic granuloma is the most common form of Langerhans cell histiocytosis and corresponds with bone lesions characterized by pain, rapid growth, and high tendency of recurrence after inadequate curettage. It is a rare disease that is difficult to diagnose clinically and radiographically because it mimics other odontogenic cysts and tumors. In this report, the reconstruction of an osseous defect with an iliac graft and a modified implant-supported hybrid prosthesis after surgical excision of an eosinophilic granuloma in the mandible of a 27-year-old male patient was described. The patient was satisfied with the functional and esthetic results of the implant-supported restoration and a 6-year follow-up showed no sign of recurrence.

Unilateral Hybrid Prosthesis for the Rehabilitation of Extensively Resorbed Maxillary Partial Alveolar Ridge: Case Report

“…Graft treatments are usually applied to excessively resorbed jaws before implant. 4,5,8 However, acute, or chronic infections may frequently cause implant losses. 4 With unsuccessful treatments and unexpected complications, the destruction in the jawbone increases, and the defects become larger.…”

“…3,6,7 This type of prosthesis has three categories: acrylic resin with a metal framework, monolithic zirconia screw-retained full-arch prosthesis, and porcelain fused to metal hybrid prosthesis. 8,9 All types of hybrid prostheses are screwed onto implants. The choice of method and material is influenced by several factors such as the patient's vertical dimension, aesthetic expectations, implant numbers, and positions.…”

Clinical and Radiographic Evaluation of Reconstruction and Prosthetic Rehabilitation of mandibular resection defects using iliac grafts combined with implant placement

“…31 Also, after the osseointegration of implants period, a provisional implant-retained prosthesis can be constructed to allow soft-tissue contouring, providing a provisional view of load distribution, function, esthetics and determining the design of the definitive prosthesis afterwards The outcomes in this study regarding success of rehabilitation and reconstruction of mandibular defects within implants in bone graft and hybrid prosthesis were similar to recent studies which concluded that implants in bone grafts and implantsupported prostheses seem to have better effect on bone resorption, possibly because prosthetic load induces the graft and prevents bone resorption. 32,33 Maximum bite force in mandibular defect patients rehabilitated with iliac bone graft and implant supported prosthesis can be an indication of the masticatory efficiency of this prothesis. Assessing the bite force and masticatory outcome of this time -consuming and demanding treatment option is important for their evaluation and acceptance as treatment modality.…”
