ABSTRACT
A introdução da tecnologia CAD-CAM no dia-a-dia das especialidades Odontológicas, em particular da Cirurgia Bucomaxilofacial e da Prótese Dentária, abriram um novo horizonte de possibilidades terapêuticas para o tratamento de diversas patologias bucais que culminam com perda de estrutura óssea e edentulismo parcial. Este trabalho faz um relato de caso clínico, no qual um paciente acometido de ameloblastoma mandibular recebeu tratamento cirúrgico e protético auxiliado pelo CAD-CAM (AU)
The introduction of CAD-CAM technology in a daily basis into Dental specialities, particularly in Oral Surgery and Prosthodontics, has opened a new horizon of therapeutic possibilities for the treatment of many oral pathologies that lead to loss of bone structure and partial edentulism. This paper brings a case report of a patient with mandibular ameloblastoma which received surgical and prosthetic treatment with the use of CAD-CAM technology (AU)

Well-placed dental implants are a prerequisite of functional and esthetically successful dental implant-supported crowns. The presence of soft tissue is essential for excellent esthetics because the dental implant or titanium abutment may become visible if the soft-tissue contour is not acceptable. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology by milling a zirconia framework that was cemented extraorally to a prefabricated titanium abutment with a reduced diameter. This ceramic abutment has the strength and precise fit of a titanium interface and also the esthetic advantages of shaded custom-milled zirconia, with no visible metal.

Diferentes desenhos de próteses totais implantossuportadas ou implantorretidas estão disponíveis para a reabilitação da maxila desdentada. Embora a preferência do paciente normalmente seja por uma reabilitação fixa, existem indicações claras onde a prótese removível é a mais recomendada. Muitos são os aspectos a serem considerados durante o planejamento buscando a decisão entre a prótese fixa ou removível. Portanto, o objetivo deste artigo foi apresentar e discutir os fatores clínicos presentes do desdentado superior que determinam a escolha do tipo de prótese, além de relatar um caso clínico de restauração de maxila desdentada. Um paciente usuário de prótese parcial removível superior apresentou-se com indicação de extração dos dentes remanescentes. Implantes imediatos e prótese total fixa provisória implantossuportada com carga imediata foram instalados. Após estabilização dos tecidos duro e mole, foram considerados aspectos como suporte labial, capacidade de higienização do paciente, entre outros, para eleição do tipo de prótese definitiva. Optou-se, então, pelo desenho final de uma prótese total implantossuportada removível, utilizando barra fresada parafusada com sistema de encaixes MK1.
Different designs of implant-supported or implant-retained prostheses are available for the rehabilitation of the edentulous maxilla. Although the patient's preference is usually for a fixed rehabilitation, there are clear indications where the removable prosthesis is the best option. There are many aspects on treatment planning to choose between a fixed or removable prosthesis. Therefore, the aim of this study is to present and discuss clinical factors that determine the choice of prosthesis, as well as to report a clinical case restoring an edentulous maxilla. A patient wearing an upper removable partial denture presented with hopeless teeth. Immediate implants were placed and restored with a full-arch provisional fixed implant-supported prosthesis. After stabilization of hard and soft tissues, factors such as lip support, oral hygiene levels, and other features were considered for the final restoration. Then, the final design included a removable implant-supported prosthesis over a milled bar and MK1 attachments.
