RESUMEN
Radiografias periapicais padronizadas pela técnica cone longo são necessárias para verificação dos níveis ósseos ao longo do tempo, principalmente no controle de pacientes com implantes osseointegrados. Este trabalho apresenta um método simples para padronização do posicionamento das radiografias, usando-se um dispositivo acrílico destacável e individualizável que pode ser colocado e retirado em qualquer momento. Desta forma, não é preciso comprar um posicionador radiográfico para cada paciente.
Periapical standardized radiographs with the long cone technique are necessary to verify bone levels over time, particularly for patients with osseointegrated dental implants. This report presents a simple method to standardize radiographs with an acrylic, detachable, customized device that can be removed and/or inserted at any time. In this way, it is not necessary to buy a film holder for each patient

Objective:To introduce a self-made film holder for standardized alignment of intraoral film and to evaluate its validity.Methods:The film holder,consisting of film backing,bite block and indicating part,was made of a kind of transparent material.20 patients were photographed using the film holder for serial dental films and another 20 patients were photographed using conventional bitewing instrument.The distance between the cemento-enamel junction and alveolar crest and the distance between cemento-enamel junction of adjacent teeth were measured on the serial films taken in the two groups.Results:The films taken by the use of film holder showed greater reproducibility than those by bitewing.Variables changes were significant smaller in film holder group than those in bitewing group.Conclusion:The film holder can be used as a instrument for standardized alignment of intraoral film.
