Osteogenic alveolar distraction: A review of the literature

Periodontally Accelerated Osteogenic Orthodontics: A Review of the Literature

“…In human bone, RAP usually lasts about 4 months and causes bone healing to occur 10-50 faster compared to normal bone turnover and is considered as a physiological emergency mechanism due to potentiating tissue reorganization by a transient burst of localized remodelling. 33 Case Selection and Treatment Planning Case selection and treatment planning are the mutual tasks of the orthodontist and the surgeon as the orthodontist determines the OTM plan, identify the teeth to provide anchorage and arch segments to be expanded or contracted while the surgeon considers the clinical periodontal status, mucogingival structure, options for minimally invasive surgery and incorporation of aesthetic needs of the patient into the treatment plan. 33,38 Orthodontic bracketing and activation of arch wires should be performed no later than two weeks postoperatively to take the full advantage of the limited time of RAP occurrence.…”

If required, as common in Class II malocclusions requiring retraction, anchorage must be established before the initiation of PAOO ™ procedure.…”

“…Interdental tissues regarding palatal or lingual gingival collars should be preserved in minimum and a tunnelling approach should be performed in maxillary central incisors area to enhance vascular supply and aesthetic outcome. 33,38,13 Decortication is performed on both labial and palatal (lingual) aspects of the alveolar bone to initiate the RAP, without creating movable segments of bone. Typically, vertical corticotomies in mid-interdental areas are connected with circular corticotomies.…”

“…33,46,39,47 Innovative approach of Wilcko 5 , addressing the need for surgical orthopaedics of the alveolus, combined corticotomy (selective alveolar decortication) with alveolar augmentation (bone grafting) and orthodontic (mechanic) force, suggested PAOO ™ to be used in cases of traditional fixed orthodontic therapy such as Class I malocclusions with moderate-to-severe crowding, Class II malocclusions requiring expansion or extractions and mild Class III malocclusions. 38 Relying on this concept, a number of reports described the relevant clinical efficiency in enhanced correction of severe bimaxillary protrusion, closure of complex skeletal open bites, facilitated molar intrusion with removable appliances, intrusion and molar up righting with mini-implants and optimization of treatment of patients with cleft lip and palate.…”

A Case of Failed Vertical Augmentation of a Post-Traumatic Mandibular Defect by Distraction Osteogenesis

“…When the level of vertical alveolar bone is too low for dental implants DO can be used [3]. In addition, DO has also been employed after trauma for restoring wounded jaws [4,5]. The major advantage to DO is that a bone graft is not necessary, it also allows the soft tissue to expand into the oral region and it is comparatively a minor surgical procedure [6].…”
