{"title":"Effect of Build Orientation on Mechanical and Physical Properties of Additively Manufactured Resins Using Digital Light Processing Technology in Dentistry: A Systematic Review.","authors":"Sujatha Paranna, Nilima Thosar, Aditi Kanitkar","doi":"10.5005/jp-journals-10024-3759","DOIUrl":"https://doi.org/10.5005/jp-journals-10024-3759","url":null,"abstract":"<p><strong>Aim: </strong>The aim of this systematic review was to evaluate the effect of build orientation on the mechanical and physical properties of additively manufactured resin using digital light processing (DLP).</p><p><strong>Background: </strong>The properties of 3D-printed materials are influenced by various factors, including the type of additive manufacturing (AM) system and build orientation.

These samples were then evaluated for SEM analysis. Energy dispersive spectroscopy (EDS) analysis was conducted on three random surface spots and two cross-section spots. Tests for detail reproduction using ADA Specification 19 die and surface roughness using a stylus were also performed. Data were recorded and statistically analyzed. (Kindly mention whether the details of reproduction and surface roughness for all the groups are considered. Also, explain what factors SEM and EDS evaluate that contribute to the evaluation of mixing efficiency).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;For elastomer surface sample EDS analysis, the &lt;i&gt;p&lt;/i&gt;-values were 0.180 (carbon) and 0.065 (silicone). Cross-section samples showed &lt;i&gt;p&lt;/i&gt;-values of 0.343 (carbon and silicone). For temporary restorative material EDS analysis, surface &lt;i&gt;p&lt;/i&gt;-values were 0.180 (carbon) and 0.394 (silicone), and cross-section &lt;i&gt;p&lt;/i&gt;-values were 0.886 (carbon) and 0.686 (silicone). The groups mixed using T-mixer tips showed no change in the mixing efficacy as compared to the group mixed using helical tips for both materials. The &lt;i&gt;p&lt;/i&gt;-values for cost-effectiveness were 0.021 for both elastomeric and Protemp temporary restorative material. The groups mixed using T-mixer tips saved more material than groups mixed using the helical tip.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;There is no significant difference in the mixing efficacy between T-mixer and helical tips for both materials. However, T-mixer tips are more cost-effective than helical tips.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Clinical significance: &lt;/strong&gt;The present study would help clinicians make a better choice of selecting the mixing tips when it comes to function as well as cost. The new T-mixer tips are proven to provide a better solution compared to helical tips, which not only would save the clinicians' cost of impression materials and interim restorative materials but also render the same homogeneity as that of the helical tips. The electron microscopic analysis provided a better insight into the homogeneity and hence the mixing efficacy of the samples. The detail reproduction and surface roughness were some additional parameters that weren't a part of the original study model. They were included for the addition of credibility to the conducted study and provided adjunctive results to those obtained by SEM and EDAX analysis.

A universal testing machine was utilized to conduct the shear bond strength test. Using a stereomicroscope with a 10× magnification, adhesive remnant index scores were also used to assess the adhesive that was remaining on the surfaces. Data was recorded and statistically analyzed.</p><p><strong>Results: </strong>The highest bond strength was found in RelyX^TM Unicem bonding agent (19.38 ± 0.84) followed by Transbond XT bonding agent (17.12 ± 1.04) and Assure Plus bonding agent (16.14 ± 1.02). A highly significant difference was found between Transbond XT vs RelyX^TM Unicem groups and RelyX^TM Unicem vs Assure Plus groups. There was no significant difference found between Transbond XT and Assure Plus (<i>p</i> > 0.001). Adhesive Remnant Index scores showed that score 1 was higher [7 (35%)] in the Transbond XT bonding agent group. Score 1 was 8 (40%) and score 2 was 6 (30%) in RelyX^TM Unicem bonding agent groups and in Assure Plus bonding agent group, score 2 was higher [9 (45%)].</p><p><strong>Conclusion: </strong>In conclusion, RelyX^TM Unicem exhibited superior bond strength with ceramic crowns when compared to Assure Plus and Transbond XT bonding agents.</p><p><strong>Clinical significance: </strong>One of the most important steps in orthodontic therapy is bonding brackets to the teeth. A high enough and long-lasting bond between brackets and artificial surfaces is necessary for orthodontic treatment to be successful, as is the requirement for a bonding agent with the highest possible binding strength. The necessity for a more dependable process to glue the artificial crown surface has arisen due to the rise in adult patients seeking fixed orthodontic treatment.
