PURPOSE: In Le Fort 1 osteotomy when a maxillary impaction is necessary, surgeons have to face different anatomical problems. (1) To determine the best bone resection route, they have to consider the situation of dental roots, infraorbital foramen and maxillary artery. (2) In case of Le Fort 1 osteotomy combined with a mandibular sagittal split osteotomy, the palate has to be replaced in horizontal position although there is no anatomical landmark. (3) In case of Gummy smiles, it can be due to either long face or short upper lip...

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental sandwich osteotomy combined with placement of an interpositional autograft prior to placement of endosseous implants...

Bony reconstruction of the mandible after surgical resection results in improved rehabilitation and aesthetics. Composite tissue transfer has transformed reconstruction, particularly in patients who have received radiotherapy. However, there is morbidity related to free tissue transfer. Free nonvascularized bone grafts have much lower morbidity. Surgeons believe that free bone grafts greater than 6.0 cm are prone to failure. The aims of this study was to assess whether bone grafts greater than 6.0 cm in length have a high risk of failure...

Introduction - The caseload of jaw osteomyelitis seem to have decreased considerably over the last fifty years thanks to the progress of oral hygiene, the appearance and the use of antibiotics, and early screening. 'Limited osteitis' remains frequent in general practice (alveolitis after dental extraction), but osteomyelitis is much rarer as evidenced by the lack of current literature and the low number of reported patients in the published series. The aim of this study was to analyze retrospectively all the cases of maxillo-mandibular osteomyelitis treated in a large academic department of Stomatology and Maxillofacial Surgery over a period of 6 years and to compare the results to data from the literature...

Langerhans cell histiocytosis (LCH), previously known as histiocytosis X, is an uncommon hematological disorder affecting infants and young children. It is the condition characterized by uncontrolled stimulation and proliferation of normal antigen presenting cells, Langerhans cells. Because of its relatively low incidence, limited data are available regarding the epidemiology of LCH, with estimation of 2-5 cases per million inhabitants per year. The purpose of this report is to describe the case of LCH in the 3-year-old male child with multiple focal involvements of bones and to discuss clinical, radiological and histopathological features of LCH and role of the dental surgeon in diagnosing and managing such lesions...

Osteopetrosis (OP) comprehends a rare group of conditions, presenting on radiographs increased bone density, deriving from irregularities in osteoclast differentiation or function. In the autosomal dominant osteopetrosis (ADO), some patients stay asymptomatic for some time, or only develop mild symptoms. The dental surgeon is often the first to presuppose the disease during routine imaging examinations, referring the patient to a specialized medical group. Furthermore, osteomyelitis is one of the major OP complications, and should be refrained through frequent dental monitoring...

Thalassemia is a genetic disorder that involves abnormal haemoglobin formation. The two main categories of thalassemia are alpha and beta thalassemia that are then divided into further subcategories. While some mild forms of thalassemia might even go unnoticed and only cause mild anaemia and iron deficiency problems in patients, other more severe forms of thalassemia can even result in death. Individuals with thalassemia can get treatment according to the level of severity of their condition. The main oral manifestations of thalassemia are Class II malocclusion, maxillary protrusion, high caries index, severe gingivitis...

Keratocysts, also known as keratocystic odontogenic tumors (KCOT), make up 7% of all odontogenic cysts and develop asymptomatically in most cases. Enucleation is the benchmark treatment. However, there are surgical alternatives. Marsupialization and decompression are necessary in some cases, mainly when the KCOT is large, thus causing an increased risk of bone fracture, or if it has engulfed important elements such as the inferior alveolar nerve or teeth, consequently causing alveolar bone growth failure. The authors describe the case of a nine-year-old child treated for a large keratocyst situated in sector 4 (lower right jaw), impacting both premolars and the canine (45, 44 and 43)...

BACKGROUND: There has been growing interest in the potential for adverse immunologic reactions to metals in biomedical devices and increasing referrals for the evaluation and management of metal hypersensitivity reactions reported in orthopedic, cardiac, gynecologic, and dental implant devices. However, there are few studies that give evidence-based recommendations on how to evaluate this issue in our practices. METHODS: We reviewed reasonable evidence and expert opinion on biomedical device hypersensitivity and published guidelines on pre- and postimplantation evaluation of delayed hypersensitivity reactions in patients suspected of possible metal hypersensitivity to biomedical devices...

BACKGROUND: The Minamata Convention embodies a world-wide reduction in the production and use of mercury and mercury-containing products and processes, including a phase-down of dental amalgam. This will change the approach to the use of direct restorative materials in the near future. There is little research as to the influence of clinical factors on dentists' decision-making which may be of use when determining the impact of any change. METHODS: An online survey relating to aspects of and attitudes to the use of direct restorative materials was distributed to all dentists who were members of the Australian Dental Association and/or Members or Fellows of the Royal Australasian College of Dental Surgeons...

Sameer Patel, Paul Ashley, Joseph Noar
INTRODUCTION: Permanent first molars (PFM) with a poor prognosis are routinely extracted in children throughout the United Kingdom. National guidelines suggest that to achieve spontaneous closure for the mandibular arch, the PFM should be extracted at 8 to 10 years of age, during bifurcation formation of the second molar. The literature is of limited quality and has suggested alternative variables that may be associated with successful space closure. Our aim was to investigate the radiographic prognostic factors associated with space closure after extraction of PFM...
