Assessment of Different Techniques for Adhesive Cementation of All-Ceramic Systems.

Background and Objectives : Modern esthetic dentistry is based on all-ceramic restorations. Dentists still have reservations about using these restorations due to a lack of understanding of the cementation technique, which depends on the type of ceramic used. The aim of the study is to evaluate the approaches and practices of clinicians regarding the adhesive cementation of all-ceramic restorations. Materials and Methods : An online questionnaire regarding the use of all-ceramic restorations and their bonding methods was designed by distinguishing the cementation of oxide and silica-based ceramics. The survey included dentists practicing in Timiș County, Romania. The questionnaire and the evaluation of the answers were designed based on the techniques and evidence from the literature. Results : Considering the work experience, we obtained two groups: group 1-1 to 6 years and group 2-6 to 9+ years. The results revealed significant values when comparing the two groups in the surface protocol and decontamination ( p = 0.005), type of cement used ( p = 0.002), and isolation techniques ( p = 0.002). Conclusions : The results show that many clinicians need additional training to improve their cementing technique and avoid the confusion caused by insufficient information about the interrelationship between the type of ceramic and the cementation procedure.
