alveolar distraction

Alberto Rocha Pereira, Nuno Montezuma, Luis Oliveira, Miguel Magalhães, José Rosa
Maxillary segmental defects are a reconstructive challenge particularly when the anterior arch is involved. Missing bone, mucosa, and teeth should be replaced; fistulae closure should be guaranteed by bone and mucosa continuity; stable functional occlusion should be achieved; and facial aesthetics restored. These defects resulting from tumor excisions, if left untreated, will cause additional problems related to interposed scar and collapse of lip and nose. Immediate reconstruction should avoid these problems and should be considered when safe tumor-free margins are obtained...

The bony augmentation of severely atrophied mandible is generally required for the purposes of prosthetic rehabilitations. The treatment strategies have been well defined in the literature ranging from osteotomy techniques to distraction osteogenesis. Visor osteotomy is the milestone of the reconstructive surgery for the atrophied mandible which has received some modifications. In the present study, the authors describe a new modification of visor osteotomy in which a complete coronal split osteotomy down to the inferior border at the mental region has been performed...

Aim of this work is to present the evolution of an innovative technique for tooth/implant supported bone distraction, leading to proper oral rehabilitation in patients with atrophic alveolar bone, even when a complete premaxilla expansion is needed, or in patients in whom implants were already present, but inserted in wrong position.Distraction osteogenesis was selected because of its moderate invasiveness, the few surgical steps needed, and the proper cost/benefits balance. This procedure is particularly suited for young patients with remarkable aesthetic demands related to active social and working life, as for elderly patients expecting lower surgical stress and risks...

Because of the high failure rates, large alveolar cleft defects cannot be successfully closed with bone grafting. Vega introduced the use of the hyrax screw for the closure of such defects by distraction osteogenesis. However, his technique was more invasive with a difficult adaptation of the appliance at the surgical table. To overcome these limitations, a completely tooth-borne trifocal distraction appliance was devised and placed after osteotomy in a 22-year-old repaired group 3 cleft patient who had a 15-mm alveolar defect on the right side...

Breach in the palatal vault leading to an abnormal communication between oral and nasal cavity is known as oro-nasal communication. It is an uncommon presentation in day-to-day clinical practice except in some patients of cleft lip and palate.Etiology may be congenital or acquired. Alveolar and palatal cleft defects are the most common etiological factor. The acquired causes may be trauma, periapical pathology, infections, neoplasms, postsurgical complications, and radio and chemo necrosis.Clinical features like nasal regurgitation of food, defective speech, fetid odor, bad taste, and upper respiratory tract and ear infection are associated with oro-nasal communication...

INTRODUCTION: A surgical technique to widen the mandible is the mandibular midline distraction: the most common indications for mandibular midline distraction are severe mandibular anterior crowding, severe mandibular transverse deficiency, uni- or bilateral crossbite, impacted anterior teeth with inadequate space, and tipped teeth. Commonly used distraction devices can be divided into 2 systems: bone-borne distraction system appliance, dental-borne distraction systems. Each system has peculiar advantages, disadvantages, and different indications...

Osteoid osteoma, a rare benign osteoblastic tumor first described by Jaffe in 1935, is characterized as a small but painful lesion that mostly affects younger people. Usually benign and harmless, osteomas are removed for pain or esthetic reasons.Piezoelectric surgery is also increasingly being used effectively in major and minor osseous oral and maxillofacial surgeries, in delicate areas. It is used regularly for various procedures, including sinus lift procedures, bone graft harvesting, osteogenic distraction, ridge expansion, inferior alveolar nerve decompression and lateralization, cyst removal, dental extraction, and impacted tooth removal...

PURPOSE: The aim of this study was to evaluate the degree of resorption that occurs following a period of consolidation in alveolar distraction osteogenesis and assess the amount of overcorrection necessary to achieve the planned height. MATERIALS AND METHODS: A retrospective observational study was conducted comprising 19 surgically treated patients, where a total of 19 extraosseous distractors were placed. All patients undergoing surgery had a panoramic radiograph and a computed tomography scan, both at the end of distraction and at the end of the consolidation period...

Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve. Several treatment alternatives are suggested: the use of short implants, guided bone regeneration, appositional bone grafting, distraction osteogenesis, inclined implants tangential to the mandibular canal, and the lateralization of the inferior alveolar nerve...

BACKGROUND: Mandibular distraction is effective for relieving airway obstruction in Robin sequence; however, mid-term dental and nerve-related complications have not been adequately studied. METHODS: Records were reviewed for patients with a single distraction in infancy using internal devices. Follow-up was 5 years or longer. Craniofacial dysmorphic syndromes and those affecting facial nerve function were excluded. Part I involved a review of dental records, whereas Part II involved assessment of inferior alveolar and marginal mandibular nerve function in returning patients with the use of 1,1,1,2-tetrafluoroethane cold stimulation and photography, respectively...

BACKGROUND: Topical anesthesia has been widely advocated as an important component of atraumatic administration of intraoral local anesthesia. The aim of this study was to use direct observation of children's behavioral pain reactions during local anesthetic injection using cotton-roll vibration method compared with routine topical anesthesia. MATERIALS AND METHODS: Forty-eight children participated in this randomized controlled clinical trial. They received two separate inferior alveolar nerve block or primary maxillary molar infiltration injections on contralateral sides of the jaws by both cotton-roll vibration (a combination of topical anesthesia gel, cotton roll, and vibration for physical distraction) and control (routine topical anesthesia) methods...

Local anesthesia forms the backbone of pain control techniques and is necessary for a painless dental procedure. Nevertheless, administering a local anesthetic injection is among the most anxiety-provoking procedures to children. This study was performed to compare the efficacy of different distraction techniques (passive, active, and passive-active) on children's pain perception during local anesthesia administration. A total of 90 children aged four to nine years, requiring inferior alveolar nerve block for primary molar extraction, were included in this study and randomly divided into three groups according to the distraction technique employed during local anesthesia administration...

Rehabilitation of the large alveolar clefts with autogenous graft or distraction osteogenesis is one of the most common treatment choices. Depending on the clinical situation such as vertical deficiencies, linear transport of the segment does not always ensure a proper closure of the cleft space. In this report, the authors present a patient in whom large unilateral cleft and vertical alveolar deficiency were closed by unilateral Le Fort I osteotomy and distraction technique using the orthodontic elastics.

UNLABELLED: Extraction, periodontitis, or trauma can cause a reduction on the alveolar ridge. This could result in an insufficient alveolar bone width and height. Different techniques of vertical bone augmentation are described in literature. However, nowadays there is not enough evidence against lateral augmentation procedures to verify if these techniques are stable over a long period of time. OBJECTIVE: This review analyses the different techniques that are used to vertically augment the bone and evaluate if these techniques are stable over a long period of time...

We have evaluated the effect of the use of platelet-rich plasma in alveolar distraction osteogenesis. Fourteen patients who were partly edentulous in the anterior premaxilla region were selected and randomised into two groups (n=7 in each group). Those in the experimental group were give platelet-rich plasma at the time of distraction, and the control group had only distraction. Selected cases had defects in the alveolar ridge of more than 3mm, and a minimal bone height of 7 mm from the alveolar ridge crest to important anatomical structures...

Osteotomies and corticotomies used in combination with orthodontic tooth movement can activate different bone responses that may be exploited to accelerate tooth movement. Segmental osteotomies around dental roots can create a tooth-bearing transport disk that may be distracted and positioned with orthodontic appliances and archwires. In difficult craniofacial repairs, alveolar segments can be guided into position with archwires and orthodontic mechanics. The corticotomy extending into the marrow space can activate bone injury repair mechanisms that accelerate bone turnover as the alveolar bone surrounding the dental roots transitions from a demineralization phase to a fibrous replacement phase and, finally, a mineralization phase...

In the 1990s intra-oral distraction osteogenesis (DO) became available as an alternative for bilateral sagittal splitosteotomy (BSSO) for advancement of the mandible. It was thought that DO would lead to more stability in the results and fewer neurosensory disturbances of the inferior alveolar nerve. However, there was no scientific evidence for this assumption. This article describes a number of recently published, prospective studies that demonstrate that BSSO is not inferior to DO with respect to stability and neurosensory disturbances of the inferior alveolar nerve...

This study examined a female patient with a lower edentulous state, who had undergone a previous alveolar distraction. A lingually malpositioned segment was found after the alveolar distraction. Therefore, an osteotomy of the distracted segment was performed and the segment was corrected into the labial side and fixed with miniplates. Good results in correcting the malpositioned segment were achieved in this edentulous patient using the osteotomy and fixation after an alveolar distraction.
