Alveolar modification by distraction osteogenesis

Esthetic rehabilitation of mutilated maxillary anterior alveolar segment by combining orthodontic osseous distraction and implant-supported crowns: A clinical report

Bony defects in the esthetic zone, especially in the maxillary anterior region, increase the complexity of surgical and prosthetic procedures. Moving teeth with preprosthetic osseous distraction techniques can be an alternative nonsurgical option to traditional regenerative or reparative surgical therapies to increase bone volume. Healthy peri-implant bone, periodontium, and adjacent teeth provide a favorable environment for implant restorations. The esthetic rehabilitation of the maxillary region after the removal of 2 ankylosed central incisors is presented. The lateral incisors were moved mesially to the central incisor positions, and implants placed in the lateral incisor positions after new healthy bone had been induced.

Bone Augmentation Techniques for Horizontal and Vertical Alveolar Ridge Deficiency in Oral Implantology

Bone deficiency is the major obstacle in implant dentistry. Guided bone regeneration (GBR) with particulate bone and barrier membranes has been the primary surgical technique used to regenerate alveolar bone for dental implant therapy. This procedure has been used in implant dentistry for more than 30 years and continues to be developed and refined for more predictable surgical outcomes. This article reviews GBR and alternative ride expansion procedures and reviews the use of various particulate graft materials. Alveolar distraction osteogenesis, used as an augmentation technique, is also presented.
