Adequate bone volume is the primary condition for successful dental implants. However, sufficient bone volume is often encountered in the vertical direction, but the bone volume in the buccolingual direction is insufficient, making it less suitable to be implanted. If the traditional spitting technique is used in the mandible, fracture and necrosis can easily occur in the labial (buccal) bone plate due to the absence of elasticity, thick cortical bone, poor blood supply, and anastomotic branch. The two-stage ridge splitting technique can be used in patients with narrow alveolar ridge in the mandible. This study summarizes the principles and conditions of application, operational points, clinical efficacy, and analysis of the causes of buccal bone plate absorption.

Key words: two-stage ridge splitting, mandible, atrophic alveolar ridge, dental implant
