Different techniques have been introduced when replacement with an implant is planned after tooth extraction. The conventional approach consists of waiting 3 to 4 months before implant placement. However, many other options are available for implant placement, including immediate implant placement (IIP), IIP and immediate provisionalization (IIPIP), and early implant placement (EIP). When the ridge is deficient, guided bone regeneration (GBR) with simultaneous implant placement is often performed. However, this procedure has potential for postoperative complications and patient discomfort, as well as an extended treatment time. The recent introduction of the Customized Alveolar Ridge-Splitting (CARS) technique can help avoid many of these problems and treat atrophic ridges that will require two or three GBR surgeries. The purpose of this case report is to demonstrate the step-by-step surgical and restorative procedures for the CARS technique and present histologic data of the new bone generated utilizing this technique.
