Vertical Alveolar Distraction Osteogenesis of the Atrophic Posterior Mandible Before Dental Implant Insertion

Abstract

ADO offers marked vertical ridge augmentation with simultaneous soft tissue expansion and stable results. ADO diminishes the need for autogenous bone graft, thus sparing donor-site morbidity. ADO of the deficient posterior mandibular alveolar ridge is useful in moderate to severe bony deficiencies and allows for adequate bone formation, which allows implant insertion.

Do short implants have similar survival rates compared to standard implants in posterior single crown?: A systematic review and meta‐analysis

“…3 There are some options for allowing the use of standard implants when this situation occurs, 4 such as guided bone regeneration, 5 onlay and inlay bone graft, 6 distraction osteogenesis, 7 and nerve lateralization. 3 There are some options for allowing the use of standard implants when this situation occurs, 4 such as guided bone regeneration, 5 onlay and inlay bone graft, 6 distraction osteogenesis, 7 and nerve lateralization.…”

“…8 Autogenous grafts, interpositional graft, like sandwich technique, and guided bone regeneration with membranes have a good success rate but there are also some disadvantages due to donor site morbidity, when autogenous bone is used, increased treatment time and high cost, in addition to some loss of bone graft height that may occur. 7 Moreover, the neurovascular bundle lateralization presents a high frequency of postoperative complications, such as paresthesia. 7 Moreover, the neurovascular bundle lateralization presents a high frequency of postoperative complications, such as paresthesia.…”

“…In the posterior region of the edentulous mandible, bone height is decreased due to resorption caused by dental loss, resulting in proximity of the mandibular canal in relation to the alveolar bone crest. 3 There are some options for allowing the use of standard implants when this situation occurs, 4 such as guided bone regeneration, 5 onlay and inlay bone graft, 6 distraction osteogenesis, 7 and nerve lateralization. 8 Autogenous grafts, interpositional graft, like sandwich technique, and guided bone regeneration with membranes have a good success rate but there are also some disadvantages due to donor site morbidity, when autogenous bone is used, increased treatment time and high cost, in addition to some loss of bone graft height that may occur.…”

“…5,[9][10][11] The osteogenic distraction is described as an advantageous technique, but its use is rendered unfeasible by the high cost of the appliance. 7 Moreover, the neurovascular bundle lateralization presents a high frequency of postoperative complications, such as paresthesia. 12,13 When tooth loss occurs in the posterior region of the maxilla, ridge resorption, and sinus pneumatization decrease the bone height for rehabilitation with standard implants.…”

Vertical distraction osteogenesis of a reconstructed mandible with a free vascularized fibula flap: a report of two cases

“…Secondary vertical distraction osteogenesis of the fibula flap before implant therapy was reported to optimize the implant position and crown-to-implant ratio for ideal prosthetic rehabilitation [3, 16–19]. Some disadvantages of this technique include mispositioning of the distracted segment, bleeding in the osteotomy, painful tension, 'segment breakage and resorption during movements of transport segment, and the extended treatment period [22, 23]. In our cases, no major complications such as insufficient ossification, osteomyelitis, or relapse of the distraction were observed, although minor localized soft-tissue infections around the distraction rod during the waiting period of osteosclerosis were recognized and the bone formation in the extended area was somewhat poor.…”
