Placement of implants in an ossifying fibroma defect obliterated with demineralized, freeze-dried bone allograft and Plasma-rich growth factor

Abstract

There has been considerable clinical interest in combining the grafts, particularly bone allografts for support for dental implants, soft-tissue support, periodontal maintenance, and ovate pontic formation. The use of demineralized, freeze-dried bone allograft (DFDBA) offers certain advantages over other graft materials and can avoid the need for a second-site surgery for autogenous donor bone. The advantages of DFDBA include handling properties, osteoinductivity, membrane tenting, and less susceptibility to migration after placement. This article will review available grafting materials and demonstrate a case of ossifying fibroma of the mandible, which was treated by curettage and hollow cavity filled with DFDBA. Six months follow-up period showed successful graft result and this grafted bone form was utilized for implant supported prosthesis.

Gnathic Bones and Hyperparathyroidism: A Review on the Metabolic Bony Changes Affecting the Mandible and Maxilla in case of Hyperparathyroidism

“…The treatment plan of ossifying fibroma is individualized and case specific, depending on the size, location, and nature and growth behavior of the lesion. Generally, the management comprises complete surgical excision of the jaw lesion till the healthy bone margin is reached, and bone grafting and reconstruction is to be considered when necessary, and this should be done after removal of the parathyroid lesions (parathyroidectomy) [ 69 , 70 ]. OF tends to recur with incomplete resection, and the recurrence is more common in younger patients; thus, orthopantomography of the face should be preferably performed once in every three years to detect any possible changes with follow-up period of at least 10 years [ 71 , 72 ].…”

Enhanced Healing of Rat Calvarial Defects with MSCs Loaded on BMP-2 Releasing Chitosan/Alginate/Hydroxyapatite Scaffolds

“…Allografts are good alternatives to bridge defects, but risk of disease transmission and adverse host immune reactions limit the use of allograft. Hence, improved strategies are urgently needed to better treat craniofacial bone defects [5] , [6] .…”

Complex Therapeutic Process due to Diagnostic Error in the Periapical Fibro-Osseous Lesion of Mandibular First Molar. A Case Report with Successful Implant Placement

“…Therefore, there is also a risk of recurrence of COD that was previously removed. Previous reports documented implant placement in the osteoporotic or hematopoietic bone marrow [15,, fibrous dysplasia [36,37], and ossifying fibroma [29,38]. Thorough debridement of the sites should be performed during implant site preparation with a clear clinical assessment of bone quality and quantity.…”
