[Application of two-stage ridge splitting technique in atrophic mandibular alveolar ridge].

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.

[Applications of minimally invasive bone splitting technique in cases with missing maxillary anterior teeth and obvious labial alveolar bone depression for dental implantation].

Purpose: The purpose of this study was to introduce a minimally invasive bone splitting technique which is suitable for cases with missing anterior teeth and obvious depression of alveolar bone in labial side, and to evaluate its clinical results.

Methods: Minimally invasive bone splitting technique was used in 8 healthy adults with bone defects in the aesthetic zone. The labial alveolar bone incisions were confined around the bone defects which were smaller than traditional incisions.
