    Study Notes

    Overview of various bone and cartilage abnormalities in the maxillofacial region

    • Osteogenesis imperfecta (OI) is a group of inherited diseases in which collagen formation is defective, causing bone fragility and deformities.
    • OI type 1 is the most common and has autosomal dominant inheritance, with features such as short stature, blue sclera, and dentinogenesis imperfecta.
    • Osteopetrosis is a group of diseases characterized by increased bone density due to defective osteoclast function, leading to bone brittleness and fractures.
    • Cleidocranial dysplasia is an autosomal dominant disorder characterized by lack of clavicles, short stature, and dental issues such as impacted teeth and cleft palate.
    • Paget's disease of bone is characterized by removal of normal bone with replacement by atypical, unorganized bone, resulting in bone expansion and increased risk of fracture.
    • Cherubism is an autosomal dominant disorder characterized by facial deformity due to multi-quadrant radiolucent lesions in children.
    • Familial gigantiform cementoma is an autosomal dominant disorder characterized by cemento-osseous proliferation involving multiple jaw quadrants and massive expansion.
    • Micrognathia is a small mandible that can be congenital or acquired and is related to class 2 malocclusion and crowding of teeth.
    • Condyle hypoplasia is a congenital or acquired condition associated with a small mandible, class 2 malocclusion, and ankylosis of TMJ.
    • Macrognathia is a large mandible associated with conditions such as gigantism, acromegaly, and Paget's disease.
    • Condyle hyperplasia is excessive growth of the condyle, leading to facial asymmetry, prognathism, and cross-bite.
    • Exostoses are bony nodules of maxillary and/or mandibular alveolus, usually asymptomatic and limited in growth, caused by bruxism.
    • Other bone and cartilage abnormalities in the maxillofacial region include Torus Palatinus, Mandibular Torus, Dense Bone Island, Stafnes bone defect, Facial osteoporotic bone marrow defect, Eruption Sequestrum, Cartilaginous rests, Cartilaginous metaplasia, and Chondroid Choristoma.
