Abstract:
Introduction: One of the most frequent pathologies in dental practice is a partial and complete destruction of the crown of the tooth. The pathogenesis of destructions can be different: secondary caries,
trauma. The goal of contemporary dentistry is to rehabilitate and restore the tooth regardless of the
degree of the crown destruction. Dentists have adopted the method of substitution by double prosthetic
piece as a technique of treatment. It consists of making two complete separate prosthetic pieces that are
cemented separately: the cast dowel and core, the artificial crown. The cast dowels and cores are appreciated for resistance against rotation and a good adaptation in the root canal.
Purpose: The analysis of the particularities of the clinical picture in subtotal and total destruction of
the tooth crowri and the treatment with the use of cast dowels and cores.
Objectives: Analysis of the features of the clinical pictures of the subtotal and total destruction of the
tooth crown; optimizing the method of treatment with the use of cast dowels and cores.
Materials and methods: In order to achieve the objectives set, have been selected, examined and
treated 7 patients (4 women and 3 men, aged between 45-61 years), diagnosed with subtotal and total
destruction of the tooth crown. The patients were assessed clinically and paraclinically and were treated
with the use of cast dowels and cores.
Results: Based on the results of clinical examination and laboratory findings, the diversity of the
clinical pictures in subtotal and total destruction of the tooth crown was found. The planning of the prosthetic construction was carried out given the morphological appearance of the root stump and its report
to the gumline, alveolar ridge, and in accordance with the biomechanical analysis of future prosthesis.
Conclusions: The clinical picture of subtotal and total destruction of the tooth crown varies depending on ethiological factors, age, types of occlusion. The design of the cast dowels and cores is determined
by the morphological appearance of the root stump and aims to ensure its stability.
