Abstract: Background: Despite technological advancements, crown and bridge failures remain a significant concern. Several factors contribute to this increased risk, necessitating extensive studies across different populations to reduce these risks. This study investigates the factors contributing to crown and bridge failure within the Jordanian population while assessing their incidence and prevalence. Methods: We conducted a descriptive study at the Royal Medical Services (RMS) dental clinic to examine the causes of crown and bridge failure. Only porcelain-fused-to-metal crowns and bridges for patients over 18 years old were included, while full-ceramic restorations, medically compromised patients, and smokers were excluded. Data collected by a specialist included age, gender, prosthesis age, and five major failure categories. The RMS ethical committee approved the study. Failure causes were categorized into five groups: mechanical failure, design failure, lab work failure, aesthetic failure, and biological and periodontal failure. These were further analyzed and compared across the population. Results: We included 300 patients with a median age of 42 years and a median prosthetic age of 60 months. Lab work issues were the most common cause of failure (67%), followed by aesthetic (34%) and biological/periodontal issues (31%). Mechanical and design failures affected 33% and 22% of patients, respectively. The patients were divided into two groups based on prosthesis age, revealing significant differences in biological and periodontal failure between the groups (p-value = 0.018), with oral hygiene issues more prevalent in patients with shorter prosthetic lifespans. Age and gender disparities were also noted between the groups, with females and younger individuals more prevalent in the shorter prosthesis lifespan group. Conclusion: Our study provides insights into the potential causes of failure for patients with crowns and bridges. Additionally, we investigated the relationship between the age of prosthetics and these factors. These findings would help improve patient care and reduce these factors.
