Hypertension is one of the most important public health problems worldwide. If undiagnosed or untreated, this pathology represents a systemic risk factor and offers unfavorable conditions for dental treatments, especially those requiring bone healing. Objectives: The purpose study was to demonstrate, by analysis mineral density (BMD), that alveolar healing process altered in spontaneously hypertensive rats (SHRs). Material Methods: Wistar SHRs were submitted extraction upper right incisor...

The intraoral approach to zygomatic fracture treatment was introduced by Keen in 1909. This technique allows both an adequate visualization of the zygomaticomaxillary buttress and reduction arch fractures. Similar techniques have been published over last 30 years. aim this study describe a modification that promotes infraorbital rim permits fixation region cases present has several advantages such as (a) only 1 incision is necessary rim, (b) it optimizes surgical time, (c) avoids periorbital scars.

Bisphosphonates are compounds used in the treatment of various metabolic and malignant bone diseases. The relation between use bisphosphonates ostenonecrosis jaws as an adverse effect drug has been intensely discussed during last few years, up to this moment, there is no consensus concerning ideal modality for condition. Nevertheless, agreement among researchers that standard goal controlling jaw osteonecrosis prevent it. Otherwise, rationale a randomized controlled trial current proven be...

Maxillofacial trauma caused by firearms has considerably increased, in which the mandibular body is site of highest incidence firearm projectiles. In these cases, use titanium plates and screws allows early restoration form function mandible with stable predictable results. Recently, conventional have been extensively used to treat comminuted fractures. Nevertheless, system presents several limitations such as screw compression against bone interface necessity precise fit plate bone. To...

Modern techniques for surgical treatment of midfacial and panfacial fractures in maxillofacial trauma lead to special problems airway management. Usually, perioperative management fractures, the surgeon needs control dental occlusion nasal pyramid assessment. For these reasons, oral endotracheal intubations are contraindicated fractures. Tracheotomy is considered by many as preferred route patients with severe but there often postoperative complications concerning this technique. The...

To evaluate the effect of reusing drills and piezosurgery tips during implant osteotomy on immediate bone cell viability through immunohistochemical analysis.Six male rabbits were divided into 2 groups then 5 subgroups-correspond to used 10, 20, 30, 40, 50 times, respectively. All animals received 10 osteotomies in each tibia, by use classic drilling procedure one group (G1) device other (G2). For technique utilized osteoprotegerin, RANKL, osteocalcin, caspase 3. Control procedures performed...

Traumatic injuries treatment of the fronto-naso-orbito-ethmoidal region has been one most challenging treatments within maxillofacial surgery, particularly extensive orbital defects, very common in this type pathologic condition. A 48-year-old man involved a car collision presented an bilateral fracture orbit medial wall, nasal bones, septum, and frontal anterior table. The clinical tomographic findings concluded diagnosis maxilla fracture. Among variety biomaterials, titanium mesh was...

The aim of this study was to gather data on trauma etiology and mandibular fracture localization in patients who presented at the General Hospital Nova Iguaçu, Rio de Janeiro, Brazil. From March 2007 December 2008, 95 with were registered a medical form, Bucomaxillofacial Surgery Department Concerning etiology, 21.05% caused by motorcycle accidents, followed interpersonal violence without use weapons (punches, kicks, bumps head, blows elbow, etc) (16.84%) firearm (14.73%). It found that...

Fractures of the zygomaticomaxillary complex are among most common face traumas. Based upon complexity and great variety reported diagnoses treatments, proposal this study was to evaluate, clinically radiographically, unilateral zygomatic fractures treated through internal rigid fixation with miniplates screws 1.5 mm. Material Method: 15 patients were analyzed, compared without so that a comparative analysis area perimeter orbital cavities could be made, as well distance from nasal point...

O tumor odontogênico queratocístico (TOQ) é uma patologia benigna, que apresenta controvérsias em seu diagnóstico e tratamento. Ocorre principalmente região de ângulo mandibular, podendo estar ou não relacionada a um elemento dentário cuja importância deve-se ao comportamento agressivo alta taxa recorrência. As causas dos altos índices recidiva observados nesta lesão estão na dependência fatores como: faixa etária, localização tamanho da lesão, gênero, tipo tratamento variante histológica. A...

The zygomaticomaxillary complex (ZMC) is the second highly incidental of facial fractures.According to anatomical complexity, there are many reports in literature about this trauma, mainly related treatment for these fractures.With purpose evaluating clinically and radiographically stability unilateral zygomatic fractures treated by surgical reduction fixed two points stable internal fixation, research was proposed.Twenty patients with were evaluated compared twenty nonfractured patients.The...

Several reconstructive methods of the alveolar ridge have been reported to make possible future rehabilitations with implants. Many these come from studies done in animals, mainly rats. With this clinical practice based on scientific evidence, any experimental procedure that can be undertaken real life is fundamental. Thus, research emulates as closely those techniques used humans are important. This study describes modification technique for block bone graft fixation (onlay) rats using "lag...

Abstract Aim To evaluate peri‐implant bone repair of implants placed into the roots delayed reimplanted teeth, in a process ankylosis and external replacement resorption. Material methods The third fourth mandibular premolars four (4) beagle dogs were used as experimental sites. study was divided three stages: stage 1 – endodontic extraction/reimplantation session, 2 decrowning session 3 implant placement. Two groups identified: (I) immediate implants, including installed fresh extraction...

Maxillomandibular reconstructions are traditionally performed by means of autogenous bone grafts collected from intraoral donor areas and extraoral such as clavicle, iliac bone, rib, tibia. The calvarial has been studied an alternative area, with a low incidence complications minimal postoperative morbidity. Complications dural lacerations associated cerebrospinal fluid leakage extradural subdural bleeding were minimized due to the use surgical trepan, allowing diploic layer delimitation...

Mandibular angle region is enshrined in literature as a fragile area because of the third molar presence further when its impaction shaping up rare complication associated with more attempts to extraction tooth. Several factors influence possibility fracture gender, age, degree dental inclusion and injuries. The best form treatment depending on case surgical, consisting placing intraosseous fixing devices. purpose facilitated conservative approach for fractures mandibular displayed. Also,...
