    The aim of this case report is to present the possibility of development of osteonecrosis around implant under load in a patient taking antiresorptive agent. A 78-year-old female complained of the mobility of implants and the swelling on lef t submandibular area. The patient was taking alendronate for the treatment of osteoporosis during 28 months. The implants were placed and functioned long before the patient received alendronate. Pus discharge and gingival swelling were observed on peri-implant area. Alveolar bone loss was seen on the radiograph. Curettage was performed and the antiresorptive agent was discontinued. Five months later, the patient revisited with swelling and new fistula formation on left submandibular area. On the radiograph, sequestrae and fracture line were seen around peri-implant area. Supportive care was performed for general anesthesia surgery. Partial mandibulectomy was performed, the result of the surgery was good and the reconstruction metal plate is maintained well. - COLLAPSE

    Implant Placement Using Alveolar Ridge Split in Atrophic Maxillary Alveolar Bone

    If the volume of the horizontal alveolar bone is insufficient during the implant procedure, it is difficult to establish a fixture of the required diameter without surgical procedures such as block bone graft, lateral bone graft, and ridge split. Among them, alveolar ridge split is known as an effective technique to increase the volume of the horizontal alveolar bone using maxillary bone elasticity. The theoretical background of this technique is to provide a basis for maintaining the implant with the expectation that new bone will form when the implant and bone graft material are operated, forming a space surrounded by the bone and periosteum. In two cases reported herein, there was no postoperative inflammatory reaction and normal healing was observed. Since then, the follow-up radiograph has shown good outcomes, and ongoing progress is being observed. Alveolar ridge split and bone graft are effective techniques for horizontal alveolar augmentation. In these cases, it was actually possible to form a stable alveolar ridge for implant placement through a successful procedure in the maxillary edentulous region. - COLLAPSE

    Spread Fit (SFIT) Ti-Base System was developed to overcome complications of conventional implant prosthesis system. This system uses a specific locking mechanism between the abutment and prosthesis instead of cement or screws, providing easy retrievability and no possibility of biological complications. This case report introduces clinical experience with a 3 - month follow-up of implant fixed prosthesis fabricated with SFIT Ti - Base System on a right maxillary posterior edentulous site. No biological complications or loss of retention was observed during the observation time. SFIT TiBase System is expected to be used in various clinical cases in the future. - COLLAPSE

    Integration of Intraoral Scanner-based Mandibular Movement Data for An Anterior Single-implant Restoration

    This article demonstrates a clinical case of the rehabilitation of a maxillary anterior tooth with a single-implant using a digital workflow. Intraoral scanner-based mandibular movement data were incorporated into the workflow for the fabrication of an immediate provisional restoration to preclude unintended loading on the restoration. The digital workflow enabled minimum adjustment to the restoration during centric and eccentric movements and allowed to achieve esthetic outcomes for both the provisional and definitive restorations. - COLLAPSE

    Forced eruption has been proposed to expose subgingival carious lesion and achieve the biologic width when treating a tooth with subgingival dental caries. The aim of this report was to propose a new digital approach of orthodontic forced eruption. By using CAD program, orthodontic forced eruption could be planned 3-dimensionally. Using an adjacent implant as an absolute anchor, orthodontic bracket and wire were not needed. - COLLAPSE
