The Fresh Frozen Bone Allograft (FFBA) to reconstruc the atrophic maxilla: evaluation of the clinical and histological viability at six and nine months in the maxillary sinus

This work aimed to analyze clinically and histologically the allogen bone graft behavior at 6 and 9 months. A leukoderm, female, 55 years old patient sought dental care for oral rehabilitation with dental implants and implant supported fixed prosthesis in the maxilla. Bilateral sinus lifting procedure were performed in a same patient, the analysis were made after 6 and 9 months, respectively. At 6 months, there was lack of a better bone remodeling in the region, associated to the presence of fibrous connective tissue within the collected tissue, showing us that this is not the best stage of tissue maturation to place dental implants. The 9 months period showed an improvement, with a more organized bone tissue surrounding particles of homogenous bone, what possibly had increased implant stability at the time of surgery. There is no doubt about the increase of clinical applications of FFBA, but there are no studies available regarding the standardization of time to load implants inserted in allografts. So papers with long-term monitoring are necessary to eliminate questions that still remain to be answered.

Radiographic and clinical evaluation of zygomatico-maxillary complex fractures treated by 2.0 miniplates system

The zygomaticomaxillary complex (ZMC) is the second highly incidental of facial fractures. According to the anatomical complexity, there are many reports in the literature about this trauma, mainly related to treatment for these fractures. With the purpose of evaluating clinically and radiographically the stability of unilateral zygomatic fractures treated by surgical reduction and fixed in two points by stable internal fixation, this research was proposed. Twenty patients with zygomatic fractures were evaluated and compared with twenty nonfractured patients. The results showed that there were no statistically significant differences among the obtained data, perimeter and area, of the treated and contra-lateral sides of the experimental group. When compared to the control group the differences were not statistically significant. We also performed a comparison of the distance between the nasal bone and zygomatic prominence in all groups the results were also satisfactory.

Fechamento de fístula buco-sinusal usando tecido adiposo bucal

The Oro-antral Fistula is a common pathologic event, which occurs an opening or communication of the maxillary sinus with the oral cavity through dental extractions of upper posterior elements whose roots have close relationship with the maxillary sinus. This study aims to clarify the Surgeon Dentist about the possible etiological factors responsible for Oro-antral Communication, to identify its clinical and radiographic signs, to explain the Buccal Fat Pad’s anatomy and functioning and to describe the surgical technique adopted front of these cases. For this, the authors present a case of a patient who had a fistula in the region where there was a dental extraction of the upper posterior element. The treatment of Oro-antral Fistula using the buccal fat pad provides to be a safe and effective surgical method, because this element presents a rich blood supply and easy access. Many authors have found that this method have a broad application, large index of success, lower risk of infection, provides a comfortable post-operative for the patient. However, it needs to be done properly so that you have minimum incidence of failures, and this requires some caution on the part of professional.

Tratamento conservador de fratura de arco zigomátio: uma visão conservadora

Introduction: The zygomatic maxillary complex is the second most affected area of the face due to injuries, surpassed only by the nasal bones. The zygomatic arch fracture is under the direct action of trauma (punch, head butt), its fragile structure, losing its normal convex curvature in the temporal area. Objective: To report a case, using a reduction technique of zygomatic arch fracture using a hook or Ginestet Barros. Case report: A male patient, 25 years of age, leukoderma, showing zygomatic arch fracture right. The patient underwent closed reduction with the hook adapted to the skin. The patient was instructed to keep care of the region for at least four weeks

Impacto do uso de fita adesiva na qualidade de vida de pacientes institucionalizados e usuários de próteses totais convencionais

Objective: Evaluate the impact of the use of strip adhesive over the quality of life of institutionalized patients and wearers of complete dentures. Material and method: Twenty-nine institutionalized patients wearers of complete denture were selected to this study and after a clinical exam, a questionnaire (adjusted and based upon the index of Oral Health Impact Profile and Oral Health-Related Quality of Life, OHIP and OHQOL) was applied to evaluate issues related to epidemiological conditions (gender and age), quality of life (pain, discomfort, functional limitations, phonetic, social, psychological and esthetic), taste and notion of implant treatment. Following this part, the patients received instruction to use the strips adhesives (Corega Fita Adesiva, Glaxo-Smith-Kline, Rio de Janeiro, Brazil), considering three in maxillary prosthesis and two in the lower prosthesis during a period of 30 days. After this period, all the patients were recall and the questionnaire was reapplied; add some adhesive performance questions, to compare the results before and after the adhesive use in terms of percentage. Result: After the adhesive strips use there were improvement of the functional, social and physcological limitation aspects, but without percentual increasement of phonetic and esthetics aspects. The results showed 65.5% of the answers stating adhesive maintenance between 6-12 hours, easy removal (68.9%), and without change the taste (89.6%). The notion for implant treatment was decreased changing from 75.8 to 37.9% after the adhesive use. Conclusion: The results enhanced a positive impact over quality of life of the respondents after the strip adhesive use, showing decrease of pain and discomfort, mainly of inferior dental prosthesis.

Análise por computação gráfica das alterações produzidas em próteses totais superiores imersas diretamente em água e pela termociclagem

Objectives: This study aimed to assess dimensional changes in acrylic resin base and artificial teeth position after water storage and thermocycling using computer graphics measurements. Methods: Twenty-four waxed replicas were obtained from a previous upper complete denture. For linear measurements, points in cusps tips of left central incisor and second premolars and molars were marked in one of the prostheses with graphite and transferred to the others using an acrylic resin guide. The prostheses were scanned after waxing, polymerization and treatments and the images were exported to “AutoCad 2002 Today®” software for measurements. Results: There was no statistically significant difference in changes of each segment for each group and between the phases evaluated after polymerization and thermocycling. In groups I and III, the values after polymerization are higher than those after treatment, which suggests shrinkage while the prostheses in group II have expanded. Conclusion: The three groups exhibited artificial teeth movement after tests in comparison to the polymerized prosthesis. The prostheses submitted to water storage in kiln at 36ºC during seven days showed different behavior than the other groups.

Prótese total imediata: relato de caso clínico

The immediate complete denture is defined as a removable or partial denture made to be installed immediately after the extraction of the natural teeth. This type of prosthesis can be used for a short period of time, for aesthetic reasons, mastication, occlusal support, convenience or for the adaptation of the patients to the edentulous state, until the final prosthesis is installed. The objective of this study was to report a surgical and prosthetic rehabilitation planning of a patient by means of an immediate complete maxillary denture, and the results obtained with this treatment modality. The immediate complete denture is a necessary, well-established, useful and effective prosthetic procedure for patients who, inevitably, will present an edentulous state, despite it is a slightly more expensive and it requires more sessions for adjust

Thus, the purpose of this study was to present a case report. This case report describes the development of a removable partial denture associated with dental implants bilaterally been monitored for 12 years, and the efficacy of the proposed treatment. The radiographic controls demonstrated no changes on bone tissue. The maxillary arch was rehabilitated with metal-free crowns. The patient was fully satisfied with this technique providing stability, esthetics, and proper function. It was concluded that the technique of using removable partial dentures associated with dental implants is viable and show the advantages of improved function, aesthetics and cost reductions in rehabilitation treatment.

Tratamento compensatorio da má oclusnao de classe lll: revisão de literatura

Class III malocclusion is less common occlusal relationship, covering less than 5% of the population. There are various forms of treatment in Class III malocclusion. Depending on how the form is expressed Class III and age of the patient, the therapy may be orthopedic and orthodontic surgical orthodontics. The objective was to review the literature of the last 10 years about ways to compensatory treatment of Class III malocclusion. Several articles were published between 04/2003 and 04/2013 in the Pubmed database from the keyword "Class III malocclusion". However, only 19 articles that addressed the compensatory treatment of Class III were selected. Based on the selected items it was concluded that the treatment of Class III malocclusions in children before the peak of pubertal growth has better prognosis with greater effects orthopedic and orthodontic minor effects. The ideal treatment option for this condition is the Rapid maxillary expansion associated with maxillary protraction of the same. The treatment of Class III malocclusion in young people after the peak of pubertal growth is doubtful prognosis. You can opt to treat rapid maxillary expansion and maxillary protraction of the same or fixed appliance, however, orthopedic effects can be the same or smaller than the orthodontic effects, depending on the age of the patient. Depending on the degree of Class III malocclusion in adults, the treatment will consist of dental compensations or orthognathic surgery.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Ectopic third molar as a cause of sinusitis

Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Male, 19- years old, with an upper left ectopic third molar located in the maxillary sinus-infraorbital region. The patient reported a bad taste and recurrent sinusitis that had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach.

Chronic osteomyelitis of the maxilla and mandible: microbiological and clinical aspects

Osteomyelitis of the mandible and maxilla are common in developing countries and their treatment may be long-standing and difficult. Thus, the aim of this study was to discuss the main biological aspects of the chronic osteomyelitis of the jaws of especial interest for dental team. These infections are associated with a complex microbiota composed mainly by anaerobic bacteria, sometimes associated with microorganisms originated from the skin and digestive tract. These data suggest that chronic osteomyelitis of the mandible and maxilla should be treated as anaerobic infections in most cases. In addition, local surgical treatments are relevant in the therapy outcome, associated to the use of antimicrobial agents, and the failure to accomplish them is a major cause of treatment failure.

Case description: patient had adento-skeletal deformity Cl III with asevereatresia of jaw and underwent a rapid maxillary expansion and surgically assisted with the use of piezosurgery. Conclusion: the piezosurgerycan be used as an alternative in oral and maxillofacial surgery wich features provide greater accuracy and safety in surgery

Controle do crescimento e da seleção folicular por fatores locais e sistêmicos na espécie bovina

The regulation of ovarian activity is an integrated process involving extraovarian signals and intrafollicular factors. In such process, gonadotropins have an important role, but not always crucial. The initiation of primordial follicle growth and the early stages of folliculogenesis can occur without gonadotropins, however FSH may affect the rate of preantral follicle growth. On the other hand, the antral follicle development from 1 to 4 mm in diameter is completely gonadotropin-dependent in bovine, and the alternation of dependency from FSH to LH may be part of the mechanism involved in follicular selection. Locally produced growth factors, such as the IGF system, work in association with gonadotropins throughout the follicular growth and can influence follicular selection. Thus, the integration of these extraovarian signals and intrafollicular factors seems to determine whether a follicle will continue to develop or go atretic. This review focuses on the interaction between gonadotropins and intrafollicular factors in follicular development and selection in cattle.
