Abstract
Splinting of the mobile teeth is a critical part of periodontal management to improve the prognosis and longevity of stable results of periodontally compromised teeth with increased mobility. Different types of splints are used in the dental field based on their mechanical and physical properties.The objective of the current in vitro study was to evaluate the flexure strength and flexural modulus of different types of splinting materials, such as: composite block, ligature wire, Ribbond®, InFibra®, and F-splint-Aid® bonded utilizing Flowable composites resin material. Seventy-five bar specimens were prepared with the dimensions of 25 × 4 × 2 mm, utilizing split metallic mold. Specimens were divided equally (n = 15) into five groups (one control group, four test groups). Different layers of splinting material were placed in between the layers of composite before curing. All the specimens were subjected to a three-point bending test by using a universal testing machine to calculate the flexural strength and flexural modulus. The entire data was subjected to statistical tests to evaluate the significance. Specimens from composite block groups showed the least mean value for flexural strength (89.15 ± 9.70 MPa) and flexural modulus (4.310 ± 0.912 GPa). Whereas, the highest mean value for flexural strength (168.04 ± 45.95 MPa) and flexural modulus (5.861 ± 0.501 GPa) were recorded by Ribbond® specimens. Inter group comparison of flexural strength showed statistically significant differences (P-value < 0.05), whereas comparison of flexural modulus showed non-significant difference among the groups (P-value > 0.05). Within the limitation of the present study, it was concluded that the Ribbond® exhibits maximum flexural strength and flexural modulus, whereas the composite blocks recorded the least values. Still, the decision making depends on the clinical scenario and the unique characteristic of each splint material.
Highlights
Patient satisfaction and improvement of oral health is considered as a major part of patient well-being during rehabilitation [1]
The result of the present study showed that the Ribbond® was found to have the highest flexural strength, followed by F-splint-Aid®, ligature wire, InFibra®, and composite block having the least flexural strength
The research carried out by Yapp and Powers in 2011, Gaspar Junior et al in 2009, and Juloski et al in 2012 showed that polyethylene fibers are more flexible than glass fibers and stainless steel wire, which is in agreement with the findings in the present study [25,29,30]
Summary
Patient satisfaction and improvement of oral health is considered as a major part of patient well-being during rehabilitation [1]. Especially in cases of severe horizontal bone loss and increased mobility, the decision of whether to preserve or extract the affected teeth is a challenging one. This decision should always be made on an individual level, taking into consideration the general factors of the patient and their expectations of the treatment [11]. The goal of the current in vitro study is to assess the two physical properties, modulus of elasticity, and flexure strength of unlike splint materials bonded utilizing composites resin material
