Treatment of Tooth Wear Using Direct or Indirect Restorations: A Systematic Review of Clinical Studies

Abstract

Tooth wear is considered a well-developed issue in daily clinical practice; however, there is no standard protocol for treatment. The aim of this manuscript was to systematically review the literature to evaluate the clinical outcomes of direct or indirect restorations for treating tooth wear. A literature search was conducted through the PubMed MedLine, Scopus, ISI Web of Science, Scielo, and EMBASE databases up to 29 April 2022. Clinical studies evaluating the clinical performance of direct or indirect restorations for treating tooth wear for a minimum follow-up of 6 months were included in the review. A total of 2776 records were obtained from the search databases. After full-text reading, 16 studies were included in the qualitative analysis. Considering the high heterogenicity of the studies included, a meta-analysis could not be performed. All studies included the rehabilitation of anterior and posterior teeth with extensive wear, using both indirect and direct restorations for a maximum follow-up of 10 years. Restoration materials included ceramo-metal crowns, full gold crowns, lithium disilicate ceramic, zirconia, polymer infiltrated ceramic networks, and resin composites. Most of the reports assessed the survival rate of the restorations and the clinical features using the United States Public Health Service (USPHS) Evaluation System criteria. Contradictory discoveries were perceived concerning the type of restoration with better clinical performance. Considering the current literature available, there is no evidence in the superiority of any restoration technique to ensure the highest clinical performance for treating tooth wear.

Chewing performance of patients with worn dentition before and after restorations: A scoping review

“…74 Few longitudinal studies tried to compare the long-term effectiveness of direct vs indirect restorations. 75 The strength of evidence that can derive from this review is limited, since it highlighted a general lack of investigations on the topic of masticatory performance in patients with worn dentition.…”

“…Other options might have been considered for the restoration of worn dentition, such as resin composite with a direct or indirect application 27 or prosthodontic rehabilitations 74 . Few longitudinal studies tried to compare the long‐term effectiveness of direct vs indirect restorations 75 …”

Special Issue “Recent Advances in Biomaterials and Dental Disease” Part I

“…Once caries are established in the enamel and dentin structures, they can be eliminated with burs; then, the enamel and dentin structures can be restored with direct or indirect dental restorations [2][3][4][5]. These restorative biomaterials bond effectively to dental tissues, providing both durability and aesthetically satisfactory results [2,4,6,7].…”

The Impact of Simulated Bruxism Forces and Surface Aging Treatments on Two Dental Nano-Biocomposites—A Radiographic and Tomographic Analysis

“…It is known that the most resistant material that withstands the oral cavity environment is the natural tooth, with its biological tissues, enamel, and dentine [ 1 ]. However, due to possible tooth diseases or traumas, these naturally engineered tissues may be damaged by carious lesions, resulting in tooth decay and defects that need to be reconstructed with oral biomaterials.…”

“…It is well known that any change in the architecture of the oral cavity may interfere with the whole oral equilibrium, disturbing it at different levels (e.g., muscles, teeth, TMJ) [ 8 , 9 ]. Consequently, parafunctional occlusal habits that generate increased forces on teeth are frequently encountered and reported to highly affect tooth-adhesive interface and tooth wear strength [ 1 , 8 , 9 , 14 ].…”
