The objective of modern odontology is to reconstitute to the patient the comfort, the function, the aesthetic form, the phonetic capability, and normal health. However, the more the patient is toothless, the more this objective becomes difficult inside traditional dentistry. As a result of continuous research of materials and techniques, permissible success is now a reality, whitewashing many challenging clinical situations. Thus, the objective of the article was to present a clinical case where association of the universal cast to long abutment pillars and EsthetiCone were used for aesthetic whitewashing. A man presented to the clinic of the Faculty of Dentistry, Universidade Estadual Paulista. After clinical examination and radiographic evaluation evidenced the necessity of substitution of fixed prostheses (15-25), he was presented with disadaptation and a favorable aesthetic solution. Ahead of the evaluated picture and considering the extension of the toothless space made, it was opted more, to the accomplishment of surgery, the setting of 2 implantations in the region and 2 in each edentate side of the posterior portion of the jaw. On 6 implants and 2 teeth, 10 metal ceramic crowns had been confectioned: 4 of them being joined in the region of the 12 to the 22 and the other 6 as unit crowns in the region of the 13, the 14, the 15, the 23, the 24, and the 25. The carried-through treatment was capable to return the aesthetic form, the function, the phonetic capability, the comfort, and the health of the verbal socket.

The demand for aesthetic restorations has increased during the last years. Dental ceramics are a successful alternative for some cases because of aesthetics and biocompatibility. Therefore, the aim of this literature review was to present the factors necessary to fabricate all-ceramic restorations with aesthetics similar to natural dentition. A search of English-language peer-review literature was completed using MEDLINE database from 1975 to 2009 including the keywords "aesthetic," "metal-free crown," "all-ceramic," and "color." It was observed that several factors influence aesthetics of all-ceramic restorations. Color scale, light source during color evaluation, characteristic of core material, color of supporting tooth, presence of root post, and type of cement are clinical factors that may influence color of the restorations. Laboratorial factors as technique for ceramic condensation, thickness, temperature, and number of firing cycles also influence the result of these crowns. Although several clinical and laboratorial factors influence aesthetics of all-ceramic restorations, the aesthetic success and longevity of these restorations depend on the integration with surrounding periodontal tissue.

Osseointegration was an innovative treatment in dentistry during the last 3 decades. The success of osseointegration is related to factors such as material biocompatibility, adequate quality of bone tissue that allows implantation, surgical technique, and macrostructure and microstructure of implant. The osseointegrated implants are successfully applied in dental clinic including oral and facial rehabilitations mainly for patients submitted to mutilating surgeries. However, patients submitted to radiation therapy present risks to treatment with implants owing to adverse effects on bone tissue. Nowadays, the literature suggests different therapies to improve the success of osseointegration such as hyperbaric oxygen therapy that aims to prepare bone and adjacent tissues to receive the implant. Therefore, the purpose of this study was to present a literature review concerning indications, contraindications, successes, and difficulties with hyperbaric oxygen therapy associated to maxillofacial implants.

Cancer is regarded as abnormal cellular multiplication; it is not controlled by the organism, and its cells present a differentiated DNA. Initially, the disease does not show clinical signs, but it can be diagnosed by laboratory examinations. When tumors are present in the maxillofacial area, the carrier can lose structures in this area, resulting to the carrier's social environment exclusion. This article aims to show incidences and causes of malignant neoplasias in the maxillofacial area.

The prosthetic treatments play a role in the rehabilitation of patients with congenital and acquired cleft palate. To prepare the surgical field and/or correct inevitable sequelae of the surgery, the rehabilitation with obturator prosthesis is an auxiliary or complementary treatment to surgical treatments. In cases where the surgical treatment is contraindicated, the prosthetic rehabilitation becomes a definitive treatment. The denture is planned and fabricated according to each patient. Therefore, the aim of this study was to discuss the prosthetic rehabilitation performed in patients with oronasal communication.
