SUMMARY:

Ceramic restorations can be essential in aesthetic and functional dental rehabilitation, but their longevity and treatment plan need to be well established. Different material options, fabrication techniques and protocols are available, but there is little scientific literature explaining the factors that generate the main failures and clinical complications related to these fixed prostheses. Thus, the present study aimed to evaluate the survival of ceramic restorations and their associated factors. Therefore, an observational, retrospective and longitudinal cohort research was carried out to follow up different types of ceramic restorations installed in the last 10 years and made following the same clinical protocol. A total of 32 patients were evaluated, totaling 256 fixed prostheses, regarding the presence of failures or complications, type of ceramic system, whether the patients had a diagnosis of sleep bruxism and whether they used an occlusal splint and the type of cement used for cementation. Participants attended a clinical evaluation to analyze the integrity of the prosthesis, answered questions that address signs and symptoms of bruxism, such as tooth wear, muscle hypertrophy and indentations. Additional information about time and materials used to make the restorations was collected from the patients' medical records. The data obtained were analyzed using the SPSS program (Statistical Package for the Social Science) 20.0 with the Chi-Square or Fisher's Exact test, with a confidence level of 95%. The results showed success and survival rates of 84.37% and 96.1%, respectively. Considering the correlation with prosthetic failures, the male gender (p=0.017), the presence of sleep bruxism (p=0.004) and wakeful bruxism (p=0.009) had a positive influence. As for the interaction with prosthetic complications, the presence of sleep bruxism (p=0.040), the type of prosthetic piece (p=0.014) and the type of cement (p=0.043) were statistically significant. Within the limitations of the study, it can be concluded that ceramic restorations had high success and survival rates, ensuring the longevity of this type of rehabilitation. Sleep bruxism is a risk factor for ceramic restorations.
