Use of the Cover-Lifting Technique in Mandibular Cemento-Ossifying Fibroma Excision to Preserve the Inferior Alveolar Nerve

Cemento-ossifying fibroma (also known as ossifying fibroma or cementifying fibroma) is a benign osteogenic neoplasm. Pain and paresthesia are rarely associated with cemento-ossifying fibroma; thus, nerves must be preserved during excision. With the advent of computer-aided techniques, the use of virtual surgical planning and a customized template can improve the precision of resection and reconstruction, reduce operating time, and improve postoperative outcomes. In this report, we describe a case of cemento-ossifying fibroma in a female patient who underwent segmental mandibulectomy and reconstruction with an iliac bone graft. Additionally, we describe a simple and effective way to preserve the inferior alveolar nerve.

A path less travelled — Short review on ossifying fibroma and osseous dysplasia

Fibro-osseous lesions (FOL) are characterized by replacement of normal bone by fibrous tissue containing a newly formed mineralized product. The mineralized product may be ossification (sometimes cementum formation) or calcification of fibrous tissue by metaplasia. These lesions have similar radiographic and histopathologic features hence the term fibre- osseous lesion is not a diagnosis, rather a description of the presence of fibrous and calcified tissue. They may be developmental (fibrous dysplasia), reactive (cemento-osseous dysplasia) or neoplastic (ossifying/cementifying fibroma). This article presents the commonly used classification for fibro-osseous lesions and an insight into a few changes that have been introduced in the recent past with emphasis on Ossifying Fibroma and Osseous Dysplasia.Ossifying fibromas are considered as benign fibro-osseous neoplasms which are principally encountered within the jawbones. Cemento-osseous dysplasias are non-neoplastic fibro- osseous lesion. Since 1971, the World Health Organization classified cemental lesions into 4 distinct entities, as follows: Periapical Cemental Dysplasia, Benign Cementoblastoma (true cementoma), Cementifying Fibroma and Gigantiform Cementoma (GC). The term, gigantiform cementoma, may imply a solitary process but it is misleading because the condition typically presents as slow-growing, multifocal/multiquadrant and expansile lesions involving both jaws. WHO classified it in Osseous dysplasia and El-Mofty et al. under Ossifying fibroma.

Peripheral ossifying fibroma: A case report

Localized inflammatory or reactive overgrowths are quite more common clinical findings on human gingiva. Most of the lesions are benign and innocuous though some have potency to transfer in to a malignant lesion. These types of lesions are difficult to identify clinically as their appearance are quite similar so only Histopathological evaluation can detect their identity. In this case report we displayed a case of Peripheral Ossifying Fibroma in maxillary anterior tooth region in 32 year old female patient along with clinical, Histopathological evaluation along with present and future treatment details. Peripheral ossifying fibroma (POF) is usually a fibromatic, non neoplastic enlargement of the gingiva which shows areas of calcification or ossification. Synonyms for POF include Peripheral cementifying fibroma, Peripheral fibroma with calcification, Calcifying or ossifying fibrous epulis and Calcifying fibroblastic granuloma.
