Traditional orthodontic tooth movement is based on the concept that application of a protracted force causes alveolar bone remodelling and adaptive changes in periodontal and dental tissues. Thus, if orthodontic tooth movement is described as a biological bone reaction to orthodontic forces mediated by the periodontal ligament (PDL), this event involves a series of sophisticated signal transduction processes that allows the PDL compression with specific histologic and biomolecular modifications. However, the preservation of the integrity of the PDL is generally difficult to achieve when it is associated with a long duration of orthodontic treatment...

Distraction osteogenesis is an important technique for the treatment of maxillofacial abnormities and defects. However, distraction osteogenesis may cause the injury of the inferior alveolar nerve. The relationship between distraction rate and nerve degeneration-regeneration shift remains poorly understood. In this study, 24 rabbits were randomly divided into four groups. To establish the rabbit mandibular distraction osteogenesis model, the mandibles of rabbits in distraction osteogenesis groups were subjected to continuous osteogenesis distraction at a rate of 1...

Alveolar ridge deficiency is considered a major limitation for successful implant placement, as well as for the long-term success rate, especially in the anterior maxillary region. Various approaches have been developed to increase bone volume. Among those approaches, inlay and onlay grafts, alveolar ridge distraction, and guided bone regeneration have been suggested. The use of titanium mesh is a reliable method for ridge augmentation. We describe a patient who presented with a localized, combined, horizontal and vertical ridge defect in the anterior maxilla...

Aim of the study was to evaluate the reliability of 6 mm long implants compared to normal length implants placed in vertical augmented atrophic posterior mandible, supporting cemented single crowns. Thirty-six patients with bilateral posterior edentulous mandible and presented a bone availability height less than 9 mm from the mandibular canal were enrolled for the participation to this study. Patient hemi-arches were randomized to receive both 6 mm-long and normal length implants (10 mm). The technique used for the vertical bone augmentation was the "sandwich" technique, using a bone substitute block as graft...

Long-standing loss of natural teeth in the mandible can lead to severe jaw atrophy and even mandibular fracture. There is no consensus on the best pre-prosthetic surgical treatment to reconstruct the atrophic edentulous mandible. The purpose of this review was to provide an overview of the existing literature and to give an evidence-based recommendation for bone grafting and future research. This systematic review was conducted according to the PRISMA statement. A literature search was performed in online databases Pubmed and Cochrane library for articles published between January 1980 and September 2017...

Varied factors, whether intrinsic or extrinsic, may lead to a decrease in the bone volume of the jaws. Trauma and pathology can be listed as examples of such factors. The aim of this study is to present the osteogenic distraction technique as alternative to augmentation of low mandibular bone volume caused by different etiologies. The first case reports a mandibular marginal resection of ameloblastoma and the second one reports a male patient presenting mandibular fracture sequelae. Both cases were treated according to the osteogenic distraction technique...

Distraction osteogenesis for the augmentation of severe alveolar bone deficiency has gained popularity during the past two decades. In cases where the vertical bone height is not sufficient to create a stable transport segment, performing alveolar distraction osteogenesis (ADO) is not possible. In these severe cases, a two-stage treatment protocol is suggested: onlay bone grafting followed by ADO. An iliac crest onlay bone graft followed by ADO was performed in 13 patients: seven in the mandible and six in the maxilla...

Mandibular distraction osteogenesis (MDO) successfully relieves obstructive sleep apnea in many infants with Robin sequence. Preoperative virtual surgical planning and fabrication of three-dimensionally printed cutting guides may lead to further improvements in the MDO technique and decrease the risk for damage to adjacent structures such as developing teeth and the inferior alveolar nerve. This report presents an algorithm for virtual surgical planning and three-dimensionally printing of cutting guides for MDO in infants with RS...

Craniomaxillofacial injuries can be complex, requiring a multidisciplinary approach. The primary survey is always the first step in trauma management prior to proceeding with further evaluation and treatment. A 26-year-old man presented with a penetrating nail gun injury through the oral and nasal cavities. He did not present in extremis but required elective endotracheal intubation for intraoperative assessment and treatment. Airway management was enhanced by the use of lingual nerve and inferior alveolar nerve blocks via the Vazirani-Akinosi technique to maintain spontaneous respiration while the tongue was distracted from the palate...

An alternative technique to reconstruct atrophic alveolar vertical bone after implant placement is presented. The technique consists of distraction osteogenesis or direct surgical repositioning of an implant-and-bone block segment after segmental osteotomies that can be used in esthetic or unesthetic cases. Initially, casts indicating the implant position are obtained and the future ideal prosthetic position is determined to guide the model surgery. After the model surgery, a new provisional prosthesis is fabricated, and an occlusal splint, which is used as a surgical guide and a device for distraction osteogenesis, is custom fabricated...
