Background: Model alignment in cases of erosive tooth wear can be challenging, and no method has been reported to outweigh the others. Methods: Extracted human teeth were mounted on two models and scanned at different times, from 1 h to 2 weeks, with an intraoral scanner (3Shape TRIOS 4) before and after immersion in Monster® energy drink and tap water. The scans were superimposed (3Shape TRIOS Patient Monitoring, Version 2.2.3.3, 3Shape A/S, Copengagen, Denmark). Best fit, best-fit tooth comparison, reference best fit using fillings, and palatal rugae as reference points were used for alignment. Surface profile differences were calculated in a cross-section view. The nonparametric Bland–Altman and Kruskal–Wallis tests were used. Results: First, statistically significant differences were marked after 4 days of immersion. The measurements obtained after 2 weeks of immersion were statistically significantly different from the measurements obtained at the different time points until 1 week. No statistically significant differences (p < 0.05) were observed among the alignment methods at any time. Conclusion: In comparison to the best-fit model, both palatal rugae and fillings can be used. The best-fit tooth comparison method is a reliable option; however, it should be used with caution in cases of major surface loss.

“…While the composite injection technique necessitates multiple patient visits due to the laboratory manufacturing process of the clear index, it simplifies and streamlines restoration placement compared to freehand direct composite restorations, which can be challenging and time-consuming chairside [ 17 ]. The approach is not only minimally invasive [ 4 ] and time-saving [ 17 ] but also offers superior bond durability to dentin compared to indirect bonding methods [ 8 , 18 ]. When choosing between direct and indirect composite resin restorations, the potential for dentin exposure underscores the importance of meticulous preparation and bonding techniques, as direct bonding to dentin exhibits superior performance to indirect bonding methods [ 8 ].…”

Esthetic concerns frequently drive individuals to seek dental treatment, leading to a rising demand for minimally invasive and time-efficient procedures. The Minimal Intervention Dentistry (MID) concept, which employs dental adhesive and resin composites, offers an effective approach for enhancing esthetics while preserving natural tooth structure. This case report outlines the esthetic enhancement of a protruding maxillary right central incisor through a direct composite restoration approach, utilizing a composite injection technique with a digital workflow. A 42-year-old male patient presented with a discolored and protruding maxillary right central incisor. After declining orthodontic treatment due to time and cost constraints, the patient opted for an alternative approach. A digital wax-up was 3D printed to create a clear silicone index, enabling precise resin composite injection to achieve the desired esthetic outcome. After internal bleaching and minimal labial surface reduction, a flowable resin composite was applied freehand to the mesial-proximal surface using a curved plastic matrix manufactured universally. The composite injection technique was subsequently employed through the incisal opening of the clear silicone index to shape the labial surface and incisal edge. In order to address insufficient tooth reduction, an additional partial labial resin composite cutback was performed, ensuring minimal reduction while enhancing esthetics. This direct composite veneer restoration, combining conventional proximal surface creation with a composite injection technique utilizing a custom-made clear silicone index prepared via a digital workflow, emerged as a pragmatic solution in a case where orthodontic treatment was not preferred. Moreover, in situations of insufficient dentin preparation, additional cutback preparation and composite placement can enhance color matching with minimal reduction. The direct composite restoration, facilitated by the composite injection technique and digital workflow, effectively rectified the inclination of the protruding maxillary central incisor, highlighting the potential of this approach in addressing esthetic dental concerns. The research and clinical technique presented in this case report hold clinical importance by offering a minimally invasive and practical alternative to orthodontic treatment and conventional restorations for patients with esthetic concerns. The composite injection technique with a digital workflow preserves natural tooth structure, reduces chair time, and enhances esthetic outcomes. This approach is particularly relevant to esthetic dentistry as it addresses anterior dental malalignment and discolored teeth while prioritizing patient satisfaction and individualized care, aligning with the principles of pragmatic esthetics and MID. The potential for long-term durability and patient satisfaction makes it a valuable addition to esthetic dental practice.

“…The load required for failure recorded in Newton (N) was divided by the surface area in square millimeters (mm 2 ) to calculate the micro-shear bond strength (τ) expressed in MPa. Area was calculated as π (3.14) multiplied by r 2 , where r is the radius of composite microcylinder (12) .…”

“…Injectable composites are widely used nowadays for anterior esthetic restorations for their good results (1) . In addition, they can be equally used with ease in potentially large and complex cases using injection molding technique (2) . Injectable composites have been introduced into the market with a contemporary approach combining high filler load and strength, wear resistance, alongside ease of flow and manipulation owing to its thixotropic qualities (3) .…”

Objective: This study was conducted to evaluate the effect of three different surface treatments on the repairability of injectable composite of different age. Materials and MethodsA total of 48 specimens were used in this study. Specimens were divided into two groups according to age of the injectable universal composite; immediate and 3-month, water-aged. Each group was divided into three subgroups according to the different surface treatments to which the composite surface was exposed (n=8); etching (E), stone roughening followed by etching (S), and air abrasion followed by etching (A). Bonding agent (G Premio Bond) was applied, followed by same composite. Micro-cylindrical specimens were subjected to microshear bond strength testing, using a Universal Testing Machine, at a crosshead speed of 0.5mm/ min. Fractured specimens' mode of failure was observed and designated as adhesive, cohesive, or mixed. Data was statistically analyzed using two-way ANOVA followed by Tukey's post hoc test.Results Two-way ANOVA test results showed that only surface treatment had a significant effect on bond strength (p<0.001), while aging and interaction were not significant (p>0.05). Post hoc pairwise comparisons showed surface treatments (E) and (S) have significantly higher micro-shear bond strength values than air abrasion (A) (p<0.05). The most dominant failure mode observed was mixed. Conclusions1. Repair behavior of injectable composite; immediate and water-aged for 3 months seems to be consistent.2. Etching and stone roughening followed by etching, as surface treatments, performed well combined with universal adhesive for repair of injectable composite of both ages, while air abrasion seems to be non-advisable.
