Direct morphological restoration of the lateral teeth

Abstract

Introduction. Direct restoration of the teeth, using the light-curing materials, is an essential branch of modern dentistry. This aspect has not only aesthetic but also functional connotations The aesthetic restorations become ideal and are being improved only by refining the old techniques and introducing the new ones. Moreover, for the lateral group of teeth it is required to respect the proportionality between the mechanical properties of the restoration materials (fracture and abrasion resistance as well as the polymerization contraction) and the aesthetic properties. In order to avoid side effects such as fracture or the appearance of secondary caries, it is necessary to restore each lost tissues with materials that have the same structural and mechanical properties. Biomimetic restoration technique, using short fiber-reinforced composite as substructure, is a recommended alternative to direct restoration and can be reliably used for coronary restorations of large cavity teeth, in areas with low resistance conditions. Aim of the study. The evaluation and optimization of the restoration technique on the lateral group of teeth, using modern materials and methods. Materials and methods.. In order to carry out the study, the research sample included patients between the ages of 18 and 50, these patients had various forms of dental pathology in the lateral group of teeth, of carious origin and their complications. Only the patients with limited or extended interest of the dentine layer lesions were selected. Results. As a result of the systematization of the clinical-theoretical information and the practical application of modern solutions for the direct restoration of the lateral teeth, we came to the conclusion that by using short fiber-reinforced composite as a base with a superficial conventional composite restoration, structural and mechanical properties, as well as the failure rate through the combination of materials has been improved, compared to those of restorations from conventional composite materials as a whole. The correct realization of the restoration technique of the lost tissues with materials that have similar properties, allows us to approach as much is possible to the biomimetic correspondence between the restoration materials and the anatomical aspect of the natural tooth. Conclusions. As a result of the analysis of the proposed method, we have come to the conclusion that the correct realization of the restorations regarding the picking of the material and the appropriate working technique will lead to excellent results. The light-cured short fiberreinforced composite has become a required material for its efficiency in restorative dentistry, which allows the restoring of large class I and II cavities in the posterior tooth group, where is a high level of masticatory pressure, due to its increased hardness. Their use not only presents aesthetic and lasting results over the years, but also reduces the working time and makes the practitioner's work easier.
