Uzupełnienie monolityczne: wewnątrz i na zewnątrz. Skuteczna i niezawodna rekonstrukcja zęba leczonego endodontycznie

Monolithic restoration: inside and out. Efficient and reliable reconstruction of an endodontically treated tooth

Composite materials have undergone significant improvements to allow enhanced esthetic results in recent years. The advent of bulk fill materials and universal adhesives has resulted in a streamlined application procedure.

Restoring teeth after endodontic root canal therapy has always presented a challenge. The wide range of materials available for post-endodontic treatment is paralleled by an equally large range of selection criteria. Glass ionomer cements and composite resin materials are generally the material of choice for clinical situations that require no endodontic posts. Sometimes amalgam is also employed because of legacy use. When endodontic posts are required, more treatment options are available as the pulp chamber is filled with an additional material after placement of the endodontic post. Prior to the advent of adhesive dentistry, cast metal posts presented the preferred treatment option. In such cases, a customized cast metal post and core build-up were placed in the root canal and pulp chamber and cemented using a zinc phosphate cement. Due to the rising demand for glass fibre endodontic posts, composite cements are now being increasingly utilized. This has led to the rise of two different clinical approaches:

1. The first approach is to create a monoblock, consisting of the core build-up material and the endodontic post. For this purpose, the core build-up material is required to feature a flowable consistency that is suitable for cementing the endodontic post. At the same time, the material should offer a sufficiently high level of strength and stability to be used as a core build-up.
2. The second approach is to fil...
