The single tooth edentulous space can be treated with an osseointegrated implant if presurgical prosthetic planning is specific and accurate. To establish accurate placement of the implant, the position of the mandibular incisor must be studied in relation to the exit point of the implant in the maxillary arch. A sufficient space for placing the implant abutment components, as well as for the crown, must be provided.

Dental implants originally were placed according to the availability of supportive bone structures. This article describes a new way of approaching implant placement: envisioning the ideal ultimate restoration and developing the treatment plan--and the implant site--to achieve that goal.

BACKGROUND: Dental procedures play a vital role in the modern dental practice. Considerable research has addressed improvements in the properties of dental porcelains. CLINICAL IMPLICATIONS: This article examines the trends in the scientific advances in dental porcelains. It highlights properties of the new low-fusing porcelains and describes indications for their use. New luting cements also are addressed.

BACKGROUND: The authors conducted a study to determine which of four consultation methods helped patients best understand a proposed treatment plan for maxillary anterior diastema closure. METHODS: The authors presented 24 subjects with four types of consultation in random order: before-and-after photographs of other patients, diagnostic models with wax setups, resin-based composite/esthetic preview/mock-ups and computer-imaging simulations. After viewing each method, the authors asked the subjects about treatment acceptability. At the end of the demonstrations of all four methods, the authors asked the subjects which consultation method helped them best understand the proposed treatment plan. RESULTS: A total of 87.5 percent of the subjects indicated that they would accept the proposed treatment plan after they were shown the computer-imaging simulation, 50 percent said they would after they were shown the resin-based composite/esthetic preview/mock-up, 41.7 percent said they would after they were shown photographs of other patients, and 25 percent said they would after they were shown diagnostic models with wax setups. When asked which method helped them best understand the proposed treatment, 54.2 percent of the subjects selected computer-imaging simulation, 33.3 percent selected resin-based composite/esthetic preview/mock-ups, and 12.5 percent selected before-and-after photographs of other patients. None of the subjects selected diagnostic models with wax setups. A chi2 test for goodness of fit indicated that these differences were statistically significant. CONCLUSION: Subjects preferred computer-imaging simulation to the other three consultation methods, and they indicated that computer-imaging simulation provided a better understanding of the proposed treatment plan for diastema closure. CLINICAL IMPLICATIONS: The use of computer-imaging simulation enhances the patient's understanding of a proposed treatment plan concerning maxillary anterior diastema closure.
This article describes how a man attempted to repair damage to his maxillary teeth with super glue. Such action is discouraged, however, because of possible adverse reactions in the hard and soft tissues.
Extreme cervix proximity of adjacent implants poses a great challenge to the restorative dentist, as accurate transfer of implant analogs to the master cast would be difficult to achieve. In this case report, a custom key transfer technique was used to precisely duplicate the relation of 2 implants (replacing maxillary left central and lateral incisors with severe cervix proximity) from the patient's mouth to the master cast. The relation of each implant was singularly transferred to a preliminary cast, and then the 2 implant analogs were positioned in a master cast for accurate clinical case reproduction. The completed master cast allowed for precise fabrication of superstructures that accurately fitted the closely related implant cervices in the patient's mouth.
This work goal is the aesthetic of health work, aesthetic seen as the fundamental relation between Man and the world, thus the individual way of happening in any praxis. It analyses the space of aesthetic expression of health workers, through the most quotidian thought, action, and manifestation. It discusses the object in the sociological and philosophical landmark and presents some categories generated from a qualitative research process. It recovers time-space-subject relation as well as the importance of imagination and the symbolism in health work comprehension, especially on work and subjectivity relation and on worker ethical aesthetic deviation rescue-turn work into an experience of self-enunciation.
