Interfacial Performance and Structural Stability of Repaired vs. Replaced Polymer-Based Composites: A 3-Year Retrospective Analysis of 'Patch-up' Restorative EngineeringBy N. Parthasarathy, V.S. Kumar Bhagavathula, Parthiban Saketharaman, Abarna Jawahar, Adhavan Balaji K.L.M., Revathy Gounder
Abstract: Objective: This retrospective study aimed to evaluate the clinical longevity and interfacial success of repairing aged polymer-based composites versus complete replacement, focusing on the integration between the existing polymer matrix and the new restorative material. Materials and Methods: A retrospective clinical audit was conducted on 50 cases (n = 50) of posterior restorations with localized defects. The sample was categorized into: Group A (n = 25), where defective sites were …

Comparative Analysis of the Structural Integrity and Dimensional Stability of Additively Manufactured Biopolymers vs. Thermoformed PETG: A 1-Year Retrospective Study on Polymer Performance in Orthodontic ApplicationsBy Sujitha Suresh, Remmiya Mary Varghese, Parthiban Saketharaman, Mounica Dommeti, V.S. Kumar Bhagavathula, Gadde Harika
Abstract: Objective: This study aimed to evaluate the long-term dimensional accuracy and structural performance of direct 3D-printed biopolymers compared to conventional vacuum-formed Polyethylene Terephthalate Glycol (PETG) composites. The investigation focused on how different polymer processing methods (additive manufacturing vs. thermoforming) influence material thinning and resistance to occlusal stress. Methods: A retrospective analysis was conducted on 60 cases (n = 60) of post-orthodontic maintenance. The sample was divided into two cohorts: Group …
