Tooth preparations for fixed prosthetic restorations can be done in different ways, basically of two kinds: preparation with a defined margin and the so-called vertical preparation or feather edge. The latter was originally used for prosthetics on teeth treated with resective surgery for periodontal disease. In this article, the author presents a prosthetic technique for periodontally healthy t...

All-ceramic restorations have been used for long as restorative material in dentistry. However, the recent advances in both the material and technology of all-ceramic have made them a more viable treatment option. Several practitioners hesitate in giving this option to patient for fear of failure. This article describes all the failures of all-ceramic material and how to prevent them. In partic...

Previous surveys have shown that subgingival restoration margins generally lead to significant inflammation of the marginal periodontium 6, 13, 16, 17 and, inter alai, trauma of the “biological width”. This term is defined as the area of the coronal periodontium of the limbus aleovaris, which consists of the connective tissue and epithelial attachment as well as the gingival sulcus (Figure 1a)....

The present in situ study investigated the influence of a preparation containing CPP/ACP (caseinphosphopeptide-amorphous calcium phosphate) (GC Tooth mousse) on initial bacterial colonization of enamel and dentin. Therefore, pellicle formation was performed in situ on bovine enamel and dentin specimens fixed to individual upper jaw splints worn by 8 subjects. After 1 min of pellicle formation G...

The histological processing of teeth is highly complicated because of containing both mineralized hard tissues and soft tissues. Depending on the type of decalcification agents used in processing, mild-to-severe deterioration in the tissue structure and inadequacies on clear staining of details by the histological stain may be observed. This study aims to compare the histological staining diffe...

OBJECTIVE In this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers. MATERIALS AND METHODS Part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. The teeth were imbedded in autopolimerize acry...

UNLABELLED The purpose of this article is to review evidence-based principles that could help optimize dentin bonding for indirect composite and porcelain restorations. More than 30 articles were reviewed, most of them addressing the specific situation of dentin bonding for indirect restorations. It appears that the combined results of this data plus clinical experience suggest the need for a r...
