[Extension of (extremely) shortened dental arches by fixed or removable partial dentures],[Extension of (extremely) shortened dental arches by fixed or removable partial dentures]

Contains fulltext : 79793.pdf (publisher's version ) (Open Access)Whether a shortened dental arch needs to be extended depends on the degree of the shortening. Four categories of shortened dental arches can be distinguished: 1. slightly shortened dental arches; 2. moderately shortened dental arches; 3. extremely shortened dental arches; and 4. asymmetrical extremely shortened dental arches. Decision-making on extending a shortened dental arch should be based on oral function and the patient's perceived impact on oral health-related quality of life. According to this principle, there is no evidence for extending slightly shortened dental arches. Extending moderately shortened dental arches is indicated in exceptional cases, especially for aesthetic reasons. In the case of (asymmetrical) extremely shortened dental arches there are reasons for extension. The extension can be restricted to restoring the arch to the level of a moderately shortened dental arch. With this treatment strategy, it is possible in many cases to conform to the current trend of using fixed partial dentures rather than removable partial dentures

[The preprosthetic treatment focusing on single- or multi-unit fixed dental prostheses]

The preprosthetic treatment is a phase of the so-called patient-centred oral healthcare cycle. The goal of the preprosthetic treatment is the elimination of pathological conditions and of uncertainties and risks to the greatest extent possible. Teeth in a reduced occlusal system can be distinguished functionally as strategic, non-strategic, and undesirable. The most important objective of the preprosthetic treatment is to establish a positive prognosis for the strategic teeth. Specific aspects relevant to the preprosthetic treatment are: referral to a specialist, requesting a second opinion, inserting 1 or more oral implants, transitional treatments, and occlusal adjustments. Subsequently, the preprosthetic treatment is evaluated to assess whether healthy circumstances have been established for the intended treatment with single- or multi-unit fixed dental prostheses

Bradysia sp. em morangueiro Bradysia sp. in strawberry

No trabalho, relatam-se os primeiros registros de Bradysia sp. (Insecta: Diptera: Sciaridae) em morangueiro (Fragaria x ananassa Duch.), cultivado no Município de Eldorado do Sul, RS. O cultivo foi realizado em sacolas com três metros de comprimento, preenchidas com substrato composto de casca de arroz e turfa, dispostas horizontalmente sobre bancadas de madeira, em ambiente protegido. A presença de Bradysia sp. foi observada na segunda quinzena de agosto de 2005. Neste trabalho, estão descritos os sintomas apresentados no morangueiro pela praga, prováveis conseqüências sobre o aparecimento de doenças e uma breve descrição morfológica da Bradysia sp., adulto e fase larval.<br>This paper describes the first record of Bradysia sp. (Insecta; Diptera; Sciaridae) in strawberry (Fragaria x ananassa), cultivated in the city of Eldorado do Sul, RS, Brazil. Strawberry was planted in plastic bags filled with a mixture of burnt rice hulls and peat and cultivated in a greenhouse. The presence of Bradysia sp was noticed in the second fortnight of August, 2005. The symptoms in strawberry and the probable consequences in terms of disease arising were described in the present study, as well as the morphological characterization of Bradysia sp. and its illustrations
