Appositional bone graft tunneled: Technical note.

INTRODUCTION: A satisfactory positioning of the dental implants is very important in the cosmetic and functional outcome in this treatment for edentulous. Insertion of an endosseous implant in the correct positioning requires sufficient bone volume. Therefore, bone-grafting procedures are becoming increasingly common, especially for the augmentation of horizontally deficient ridges. PRESENTATION OF CASE: Many patients have been treated with this technique of appositional Bone Graft Tunneled at our clinic since 2005. The method will be completed through the technical note of a surgical procedure involving a dental implant used for edentulous space rehabilitation in the jaws and the tunnel technique with an appositional bone graft, using the mandibular arch as the donor area. DISCUSSION: The substitution of screws to stabilize the bone graft for the tunnel technique allowed the surgery to be performed in a shorter time. The advantages were as follows: the absence of complications associated with conventional titanium screws, the preservation of the integrity of the periosteum, and the fact that there was no need to remove the screws through relaxing incisions in the gingival mucosa before placing the implant. CONCLUSION: The tunnel technique for onlay bone grafting is a simple and easy to perform technique, which is completed with less surgical time and at a lower cost and has presented highly predictable results and high success rates.

Psammomatoid juvenile ossifying fibroma: case study and a review.

BACKGROUND: The group of fibro-osseous lesions from the maxillofacial region is very heterogeneous, but what they all have in common is the substitution of normal bone by fibroblasts with the consequent formation of collagen fibers, as well as substitution by different types of mineralized tissues which may be similar to bone or cement. Within this group of lesions, the juvenile ossifying fibroma is found, considered a rare and recurrent benign fibro-osseous neoplasia. The term juvenile ossifying fibroma has been used in the literature to describe two histopathological variations of conventional ossifying fibroma. These variations are trabecular juvenile ossifying fibroma and psammomatoid juvenile ossifying fibroma. Psammomatoid juvenile ossifying fibroma is an uncommon bone-forming neoplasm with aggressive local growth. Diagnostic of this lesion occurs after the correlation of clinical, imaging, and histopathological findings. Proposed treatments range from enucleation and curettage to resection of the tumor. OBJECTIVES: The present article has as its objectives to report an uncommon case of a 4-year-old male patient treated by conservative approach and revise the literature on juvenile ossifying fibroma. CONCLUSIONS: Psammomatoid juvenile ossifying fibroma, for its being very uncommon, warrants further investigation in order to establish the best treatment, principally in children, with a view to minimizing mutilating treatments. In the case examined, a conservative treatment was chosen, where the surgeon established curette and cryotherapy, and the reintegration of the child in his social environment, without relapse during the first year of therapy.

Avaliação do estado nutricional pré e pós-operatório em pacientes submetidos à cirurgia ortognática: estudo piloto / Evaluation the nutritional status of subjects before and after orthognathic surgery: pilot study

Objetivo: Avaliar a importância do acompanhamento nutricional em pacientes submetidos à cirurgia ortognática através de análise comparativa entre os resultados antropométricos e laboratoriais mensurados nos período pré e pós-operatório. Metodologia: Dez pacientes estudados com valor mediano de idade 26,5 anos, seis do sexo feminino (60%) e quatro do sexo masculino (40%) e diferentes raças (dois brancos, cinco negros e três mestiços). Todos os pacientes foram orientados pelo nutricionista a ingerir dieta líquida e/ou pastosa hipercalórica e suplementação adicional (2500 Kcal/dia) durante o período pós-operatório. As avaliações do estado nutricional, medidas antropométricas (peso, altura e índice de massa corpórea) foram realizados no pré e pós-operatórios, enquanto os exames laboratoriais (proteínas totais, albumina e globulina), foram realizados em três períodos distintos; pré-operatório, 15º Dia Pós Operatório (DPO) e 45ºDPO. Resultados: Ao se comparar os índices antropométricos e os exames laboratoriais entre o período pré e pós-operatório, observou-se que houve pouca perda de massa corporal, recuperada durante o decorrer do estudo, e manutenção dos indicadores laboratoriais nutricionais. Conclusão: A terapia nutricional no período pós-operatório de pacientes submetidos à cirurgia ortognática, dieta hipercalórica e suplementação, ajudaram a manter os índices do estado nutricional em níveis semelhantes aos obtidos no pré-operatório...

Objective: evaluate the importance of nutritional monitoring in patients submitted to orthognathic surgery through anthropometrics and laboratory analysis in the pre and post-operative period. Methods: 10 patients were studied with the average age 26.5 years, 06 female sex (60%) and 04 male sex (40%) of the different races (02 white, 05 black, and 03 mixed races). In the post-operative period all the patients were submitted to the oral liquid diet with hypercaloric nutritional supplementation for 45 days. The evaluations of the nutritional status, anthropometrics measurements (indices of body mass) and laboratory studies (total proteins, albumin and globulin) were carried out in three distinct periods; preoperative, 15th postoperative day, 45th postoperative day. Results: to compare anthropometrics measurements and laboratory studies between the period pre and post-operative, it was observed that there was little loss of body mass and stabilization of the laboratory indicators. Conclusion: the nutritional therapy and hypercaloric supplementation keep the good nutritional status during the post-operative period of patients submitted the orthognathic surgery... (AU)

Actinomycotic osteomyelitis of the mandible: an unusual case.

BACKGROUND: Actinomycotic osteomyelitis is an infection in soft tissues and/or bones, being associated with trauma or a previous nonspecific infection. This article presents an unusual case of mandibular osteomyelitis caused by Actinomyces. CASE REPORT: A 19-year-old male patient was referred for endodontic treatment of the lower right first molar about 16 months ago and removal of lower right third molar approximately 3 years before. The panoramic radiography showed change in bone density in the region of ill-defined mandibular angle boundaries, and the computed tomography (CT) showed mixed density image in the mandibular angle, with discreet expansion of cortical vestibular and lingual. Biopsy was performed, and content was aspirated in small quantity and purulent tissue fragments were sent to anatomical-pathological examination. The collected purulent secretion was colored for cytopathologic study, which showed infection by Actinomyces. DISCUSSION: In this case, the causative agent was Actinomyces, which makes it even more unusual. The origin of the microorganism has not been clearly established; however, the diagnosis allowed long-term treatment with antibiotics, which has resulted in the resolution of the case.

Anquilose da articulação temporomandibular tratada por artroplastia interposicional com enxerto costocondral: relato de caso clínico / Ankylosis of the temporomandibular joint treated with interpositional arthroplasty and a costochondral graft: a case report

A anquilose da articulação temporomandibular (A.T.M) refere-se à união intracapsular do complexo disco-côndilo à superfície articular do osso temporal, restringindo, dessa forma, os movimentos articulares. A anquilose da A.T.M possui etiologia multifatorial, podendo estar ligada a processos infecciosos agudos na região articular, exposição a trauma, radioterapia e tumores na A.T.M. A anquilose causa distúrbios funcionais nos pacientes acometidos, como capacidade de mastigar limitada, dificuldade de fonação, limitação da higiene bucal, problemas na respiração, impedimento da erupção normal dos molares inferiores. o diagnóstico é feito pela correlação dos aspectos clínicos e imaginológicos. o tratamento para anquilose da A.T.M é constituído de terapia cirúrgica, com a finalidade de remover a massa anquilótica, reconstruir a articulação e devolver ao paciente as funções que foram comprometidas em decorrência dessa patologia.o presente artigo tem por objetivo relatar um caso de anquilose na A.T.M e seu tratamento por artroplastia interposicional com enxerto costocondral em uma paciente pediátrica. Conclui-se que a artroplastia interposicional com reconstrução, utilizando enxerto costocondral, representa uma boa alternativa para o tratamento de paciente com anquilose da ATM que se encontra em fase de crescimento, por se tratar de uma reconstrução com enxerto autógeno e material de interposição autógeno, evitando a rejeição, além das vantagens morfológicas apresentadas.

Ankylosis of the temporomandibular joint (TMJ) refers to the fusion of the capsule of the disc-condyle complex with the joint surface of the temporal bone, which restricts the movement of the joints. Ankylosis of the TMJ is multifactorial and may be related to acute infectious processes in the joint region, exposure to trauma, tumors and radiation therapy. Ankylosis produces functional changes in those affected, such as limitation of the ability to chew, difficulty in speaking, limited oral hygiene, respiratory problems, and difficulty with the normal eruption of the lower molars. diagnosis is made by correlating the clinical features with the results of imaging. The surgical treatment of ankylosis of the TMJ consists in removing the ankylotic mass, reconstructing the joint and restoring the patient's functions that have been impaired as a result of the pathological condition. This article reports a case of ankylosis of the TMJ treated by an interpositional arthroplasty and a costochondral graft in a pediatric patient. We conclude that interposicional arthroplasty with reconstruction using a costochondral graft, represents a good option in the treatment of patients with ankylosis of the TMJ, which is in a phase of growth, because it is a reconstruction using an autogenous graft and autogenous interposition material, thereby preventing rejection, in addition to its morphological advantages.
