Rehabilitacion oral sobre implantes instalados por medio de la tecnica sin colgajo (flapless) y carga inmediata

The oral rehabilitation with osseointegrated implants is a well-documented treatment with high rate of success. Nevertheless, demands related to treatment time and surgical technique began to appear. In this context, the procedure of immediate loading in which the dental prosthesis is placed right after implant surgery has become a constant practice. Although immediate loading has been an important advance, minimally invasive procedures, such as implant placement without raising a mucoperiosteal flap (flapless) are increasingly being performed. Association of immediate loading with the flapless technique improves acceptance by patients and professionals, because no suturing is required. Moreover, it reduces swelling, bleeding during and after surgery, postoperative pain, surgery time, discomfort and hematoma, as well as the need for postoperative medication. These characteristics ease the stages of rehabilitation soon after implant placement, cooperating with prosthodontist's work. Thus, the proposal of this study is to present a clinical case of oral rehabilitation with osseointegrated implants and fixed prosthesis in both arches, in which the flapless technique was applied, followed by immediate loading. It will discuss the diagnosis, prosthetic planning, surgical/prosthodontic procedures and follow-up for 20 months.

Sistemas cerámicos puros parte 1: una evolución basada en la composicíon

The continuing advances in technology, dental materials and equipment have contributed significantly to improve the level of esthetic dentistry today. Among these innovations, development of pure ceramic restorations has evolved to give different alternatives. Dental ceramics have presented a rapidly technological changing to improve mechanical and optical properties. Currently there are several systems of metal free ceramics with excellent mechanical and optical properties, for making crowns and plurals. These modern systems are presented with various compositions and different preparation techniques, making these more versatile. Within this perspective, the dental market offers a huge range of new indirect and metal-free materials for prostheses, providing new options, plus also new questions to decide among the available alternatives. The aim of this review is take a view of the different ceramic systems in terms of its composition and different techniques of production.

Esplenomegalia em cães: estudo retrospectivo

The aim of this study was to review the prevalence of canine splenic disorders by means of a retrospectiveanalysis of histological diagnosis after splenectomy. The results were confronted with laboratory findings, clinical signs and presence of cardiac arrhythmia and hemoperitoneum, in an attempt to establish the differentialdiagnosis of splenomegaly. One hundred and nine dogs assisted at the Veterinary Hospital of theSchool of Veterinary Medicine and Zootechny, University of São Paulo, were included in the retrospectivestudy, between 2002 and 2009. The average age was 10 years old ± 3, with no sexual predilection. Mixedbreed dogs was the most affected kind, and average weight was 22 kg ± 13. Overall, 52% (57/109) of dogswere splenectomized due to non-neoplastic diseases and 48% (52/109) to neoplastic diseases. Among thelatter, the most common diagnosis was hemangiosarcoma (28 dogs; 54%). Most frequent clinical signs includedanorexia, lethargy and vomiting. Results showed that dogs with low red blood cell count, low hematocritvalues and/or hemoperitoneum were more likely to have splenic malignant neoplasm. On the otherhand, sex, breed, size, age, cardiac arrhythmia and other laboratory parameters were not determining factorsin the differentiation of splenomegaly.

Acute effects of flexible pole exercise on heart rate dynamics

Introduction: Exercise with flexible poles provides fast eccentric and concentric muscle contractions. Although the literature reports significant muscle chain activity during this exercise, it is not clear if a single bout of exercise induces cardiac changes. In this study we assessed the acute effects of flexible pole exercise on cardiac autonomic regulation.Methods: The study was performed on 22 women between 18 and 26 years old. We assessed heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency (HF, LF and LF/HF ratio) domains and geometric indices of HRV (RRTri, TINN, SD1, SD2 and SD1/SD2 ratio). The subjects remained at rest for 10 min and then performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 min and HRV was analyzed.Results: We observed no significant changes in time domain (SDNN: p=0.72; RMSSD: p=0.94 and pNN50: p=0.92) or frequency domain indices (LF [nu]: p=0.98; LF [ms(2)]: p=0.72; HF [nu]: p=0.98; HF [ms(2)]: p=0.82 and LF/HF ratio: p=0.7) or in geometric indices (RRTri: p=0.54; TINN: p=0.77; SD1 p=0.94; SD2: p=0.67 and SD/SD2: p=0.42) before and after a single bout of flexible pole exercise.Conclusion: A single bout of flexible pole exercise did not induce significant changes in cardiac autonomic regulation in healthy women.

Study selection: pediatric articles (original articles and case report) that investigated the obstructive sleep-disordered breathing in children Data synthesis: The obstructive sleep-disordered breathing can lead to serious cardiovascular consequences such as pulmonary hypertension, pulmonary edema and anatomic and functional abnormalities Conclusions: The knowledge of cardiovascular repercussions allows in better management of pediatric patients and may result in positive consequences for treatment and follow up of these patients.

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.

O uso de drogas anticoagulantes e antiplaquetárias orais em pacientes cirúrgicos ambulatoriais: revisão de literatura

The oral anticoagulants (AOC) and platelet antiagregants are drugs used for the prevention of thromboembolic phenomena, such as pulmonary embolism in patients with atrial fribrilation heart valves, thrombosis and pulmonary embolism. For patients who are undergoing surgical procedures-dentistry were asked to discontinue the use of anticoagulants until the value of the INR remained = 2.0, that in order to avoid trans and hemorrhages in the postoperative period. However, the AOC can cause the formation of a clot, leading to obstruction of blood pathways. Thus, it became doubtful the medicine for surgery, in which local hemostatic measures would be sufficient to promote hemostasis. Thus, the objective of the review was to evaluate the risk of bleeding in patients AOC users that are subjected to surgical procedures, through a bibliographical survey carried out in relevant clinical studies published between 1990 and 2012, by the MedlinePubMed data. In this review of literature was concluded that the benefit of thromboembolism prevention overcomes the risk hemorrhage, therefore, it is recommended to keep the dose of anticoagulant therapy unchanged for patients undergoing oral surgery and implant dentistry, using appropriate INR levels with the assistance of local hemostatic. In addition, a refined surgical technique should be performed in these patients. With respect to the most invasive oral surgery, with a risk of bleeding, treatment may be necessary in conjunction with the medical staff.

Sistemas de retenção O'ring e barra-clipe em overdenture mandibular

The dissatisfaction of the treatment with mandibular complete dentures in edentulous patients has been a constant problem in Dentistry. Often, the absence of stability and retention, resultants of a physiologic condition and alveolar ridge resorption, bring reduction of chewing force, speech problems and social life interference. In these cases, the rehabilitation over osseointegrated implants can be an effective and safe alternative of treatment. When it is not possible to put implants in appropriate number and disposition, it is necessary to make a simple and low costing prosthetic planning, which makes resurge the overdentures. Various implant supported attachment systems for overdentures have been developed in the dental market. Thus, intending to facilitate the professional choice, this study review the literature about attachment systems O’ring and bar- clip in its following aspect: retention level, stress distribution, hygiene complications and patient satisfaction.

Sobredentaduras mandibulares inmediatas: revisión de literatura

Conventional complete denture even though well confectioned, could present deficiencies in the retention, stability and support, in addition uncomfortable and retention of food below it. The overdentures have been considered an alternative to resolve problems and negative experiences with the conventional dentures, thus also can be an alternative to the complex treatments (surgical/prosthetic) with implant-supported prosthesis. In the attempt to reduce the healing time for the confection of the dentures showed higher rates of success to the implants when immediate mandibular overdentures were used in the rehabilitation of edentulous patients. The aim of this paper was to discuss by means of a Literature review, the viability of the use of mandibular implant-supported overdentures. The immediate mandibular overdentures have been showed like a reproducible method, predictable and confidence to provide an efficient function to the total edentulous patients.
