Abstract: The morphology of alveolar bone defects is the key factor affecting the effect of bone regeneration and it is often an important basis for selecting bone augmentation method. At present，the evaluation and classification methods of alveolar bone defects morphology are diversified，which leads to the lack of standardization in clinical application. Moreover，most evaluation and classification methods do not reflect objectively or comprehensively the defects parameters related to bone regeneration effects. In recent years，cone beam CT combined with digital technology has provided new methods for clinicians to quantitatively analyze the morphology of alveolar bone defects，opening up a new approach to evaluating alveolar bone regeneration effects. In the current article，the relevant factors that affect bone regeneration were reviewed，the general classifications and evaluation indicators of alveolar bone defects were summarized，the researches on the relationship between quantitative factors of alveolar bone defects morphology and bone regeneration results were analyzed，and a risk evaluation table for bone augmentation at implant site was proposed. The aim was to provide reference for clinicians to evaluate bone defects and make clinical decisions.
