Relevance of the problem. The use of lithium disilicate restorations is promising due to the rapid development of adhesive bonding systems, cements, and cementation techniques, as well as the increasing popularity of CAD/CAM technology. When planning the cementation of lithium disilicate ceramic fixed prostheses, it is necessary to consider the type of restoration and to choose the most suitable material. Aim of the work. To evaluate the choice of lithium disilicate restoration cementation material by prosthodontists and to compare the results with the recommendations of cementation material selection and methodology in the scientific literature. Objectives of the work: 1. To evaluate the differences in the choice of cementing material depending on the type of restoration. 2. To determine the most used luting materials by prosthodontists and the reasons behind their choice. 3. To compare the cementing materials recommended in the scientific literature and used by specialists in prosthodontists and general dentists for lithium disilicate restorations. Material and methods. An online questionnaire was developed for prosthodontists and dentists who do prosthodontic work. The survey was shared in online groups of dental specialists. The survey included questions about which dental luting materials dentists use for different types of lithium disilicate restorations and what determines their choice. A total of 50 dentists responded. Statistical analysis was carried out using IBM SPSS 29.0 and Microsoft Office Excel 365. Results. Dentists frequently use dual cure cement when luting onlays and crowns (86% each) and light cure cement for veneers (74%). Dentists with less clinical experience (up to 10 years) are more likely to use preheated composite resin as a luting agent for lithium disilicate onlay (p=0,004). Conclusion. Prosthodontists prefer dual cure resin cement for lithium disilicate onlay and crown, and light cure resin cement for veneer restorations. A vast majority of respondents use Panavia and Variolink resin cements. The most common reasons cited for this choice are personal clinical experience, clear instructions and recommendations from colleagues. Most prosthodontists follow the recommendations in the scientific literature when choosing a luting material. |
