[Solving esthetic problems of coronoradicular metal posts in anterior teeth. Case report]

Interest in esthetic dentistry is growing recently. Patients visit dental offices not only to exchange fillings or perform bleaching, but often to demand replacement of unaesthetic prosthetic crowns. Problems appear when dealing with a prosthetic crown of an anterior tooth reinforced with a coronoradicular metal post. Firstly, there exists the risk of color mismatch of the all-ceramic crown due to the old coronoradicular post. Secondly, dark coloration of gum tissues may appear and prove particularly worrisome for a patient with a high lip line. In some cases, root canal retreatment may be necessary due to incomplete root canal filling, apical periodontitis, or interference between filling material and future adhesion of the fiber post to root dentin. This article is a case report describing coronoradicular metal post removal with ultrasound. Indications and contraindications for the procedure are discussed.
