#bone resorption

• Acro-osteolysis — A destructive pathological process characterized by the progressive bone resorption, decalcification, or dissolution of the terminal (distal) phalanges of the fingers and toes. This severe skeletal structural phenomenon can be congenital or acquired, observed on X-rays as a shortening or disappearance of the phalangeal tufts, and is encountered as a major symptom in systemic sclerosis, secondary hyperparathyroidism, occupational chronic exposure to vinyl chloride, or rare genetic syndromes (such as Hajdu-Cheney syndrome).
• Alveolisis — A destructive pathological process consisting of the gradual resorption, atrophy, or destruction of the bony tissue of the alveolar process that supports the teeth in the jaws. This structural osteolytic phenomenon frequently occurs as an advanced complication of periodontal disease (periodontitis) or due to repeated occlusal trauma, leading to progressive tooth mobility and, ultimately, to the loss of the affected tooth.
• Alveoloclasia — A destructive pathological process characterized by the active resorption, dissolution, or fracturing of the bony tissue of the alveolar process under the direct action of osteoclast cells. This severe osteolytic phenomenon, structurally correlated with advanced stages of chronic marginal periodontal diseases, causes the loss of the tooth's rigid support, leading to progressive tooth mobility and the subsequent loss of the affected teeth.
