Background:
Maxillofacial materials have been developed to provide natural and long-lasting prosthetic solutions for patients with facial anomalies caused by trauma, surgery, or congenital diseases. The durability and lifespan of maxillofacial silicone materials are important factors to consider in prosthetic rehabilitation. The tear strength of these materials is a crucial characteristic that directly affects their ability to withstand wear, tear, and deformation over time. Comprehending the comparative examination of tear strength among various maxillofacial silicone materials is crucial to identifying the most appropriate material. This study aimed to compare tear strength among different types of maxillofacial silicone materials.
Methods:
Pertinent data for the current study were obtained from three databases: Web of Science, Cochrane, Scopus, Embase, and PubMed. The study objectives and topics were used to identify pertinent terms, which were then combined using the Boolean operators "OR" and "AND". The search queries generated for each database were utilized to obtain articles from the beginning until December 2024.
Results:
Twelve articles were eligible to be included in this study. The described types of maxillofacial silicone materials included VST50F maxillofacial silicone, A-2186 Platinum RTV Silicone Elastomer, and M511 Platinum silicone elastomer. The tear strength proportions of the VST-50 maxillofacial silicone elastomer, A-2186 RTV, and M511 platinum were 0.37, 0.29, and 0.33, respectively. The addition of additive particles to silicone maxillofacial materials significantly improved tear strength (SMD = 4.25, 95% CI: 2.32, 6.18, (p = 0.0001)) compared to the control group.
Conclusions:
Based on the present finding, 2186-RTV platinum maxillofacial silicone material exhibits strong tear strength, followed by VST50F maxillofacial silicone as a result of reinforced nano-filler particles (TiO2).
