Causes Maxillary Atrophy
What are the causes of maxillary atrophy?

Maxillary atrophy usually occurs after tooth extractions, either due to dental infections and tooth decay, fractures or periodontal infections around the teeth, such as periodontitis or pyorrhea. Shrinkage of the maxillary bone can also be caused by losing dental implants or by bone graft failure. When sinus grafts fail, it is normal for maxillary atrophy to manifest more severely in the posterior areas of the mouth. Hormonal factors can also influence maxillary bone loss and is therefore common in middle-aged women. Finally, maxillary bone loss can be the result of resective neoplasm treatment, which affects the craniofacial bones.
