[Tooth replacement in the anterior region: specific problems and standard options].

The problems involved in the loss of anterior teeth differ essentially from those in the premolar/molar region. Firstly, missing anterior teeth result in unacceptable changes in appearance and speech, making treatment mandatory. Secondly, the dentist has to consider specific aspects, such as aesthetics, resorption of the alveolar bone, loading of the abutment teeth, form of the clinical crown and incisal guidance. Treatment options comprise orthodontic closure, periodontally supported removable and fixed appliances and appliances supported by implants. The advantages and disadvantages of the different options are indicated.
