The aim of this study was to evaluate and compare the surface roughness and gloss—both initially and after simulated toothbrushing—of three 3D-printed crown materials subjected to different surface treatments: varnishing, polishing with diamond-impregnated rubber polishers, and polishing with a bristle brush and paste. Disc-shaped specimens (n = 90) were 3D-printed using three commercially available crown resins (Rodin Sculpture, VarseoSmile TriniQ, and OnX Tough 2) and post-processed per manufacturers’ instructions. Specimens were divided into three surface treatment groups: application of a light-cured varnish, polishing with a two-step diamond-impregnated rubber polisher, or polishing with a bristle brush and abrasive paste. Surface roughness and gloss were measured after treatment and again following 20,000 cycles of simulated toothbrushing. Additional specimens were prepared for Vickers microhardness testing and determination of filler weight percentage (wt%). Statistical comparisons were performed using two-way ANOVA with significance set at p < 0.05. Results: The varnish provided the statistically lowest roughness of all surface treatments for all materials. The bristle brush and abrasive paste polishing protocol produced the greatest gloss for the softest material (VarseoSmile TriniQ) and lowest gloss for the hardest material (Rodin Sculpture), whereas the two-step diamond-impregnated rubber polisher produced an equivalent gloss on all materials. Following toothbrushing, roughness was minimally affected; however, gloss was considerably reduced. Conclusions: All tested polishing and varnishing methods achieved clinically acceptable surface roughness (Ra < 0.2 µm) that persisted after simulated toothbrushing. Notably, the two-step diamond-impregnated rubber polisher produced consistent gloss across all materials, while the bristle brush and abrasive paste polishing protocol performed better on softer materials, and varnish application resulted in equal or superior gloss and roughness retention compared to polishing.

This report describes the importance of and outlines steps for additive wax-up and diagnostic mockup for anterior teeth as diagnostic and driving tools for non-prep and minimally invasive veneer preparations. A 35-year-old male presented to the clinic with the chief complaint of spaces between his front teeth. Diagnostic additive wax-up provided the possibility of offering minimally invasive preparations, and the use of a diagnostic intraoral mockup fulfilled the patient’s esthetic demands for treatment approval. Veneer preparations over the diagnostic mockup were provided as they are minimally invasive. Ceramic veneers were hand-crafted following the previous diagnostic wax-up, and restorations were bonded under rubber dam isolation. Overall, additive wax-up provides information needed to know if minimally invasive veneer preparations are possible, and the diagnostic mockup displays a physical, tentative outcome for the patient’s evaluation before irreversible tooth preparations. These simple, but effective, techniques can drive the diagnosis and prognosis of minimally invasive veneer restorations.

Background: We compared the repeatability of the shade determination of resin composite restorations and acrylic teeth in light and darker shades at baseline and after an aging process through two digital tooth color-matching methods: using a Trios 3Shape intraoral scanner and using a Vita Easyshade Compact spectrophotometer. Material and Methods: Forty upper central incisor acrylic teeth in the shade A1 (n = 10) and A3 (n = 10) were randomly assigned to be restored with Filtek Bulk Fill in the shade A1 (n = 10) or A3 (n = 10). Subsequently, 20 Class V cavities were prepared in a standardized manner (mesio-distal = 3.0 mm, cervical–occlusal = 2.0 mm, depth = 1.5 mm). Cavities were restored using an universal adhesive system and resin composite in two increments and were light-cured. The shade difference between the resin composite Class V restorations in acrylic teeth of the A1 and A3 shades was evaluated at baseline and after aging. Aging was simulated using ultraviolet light for 120 h. An Easyshade device and an intraoral scanner were used under D65 illumination. Measurements were taken five times, on top of the restoration and on the acrylic teeth, in a randomized manner. Results: Data analysis was on the calculation of the arithmetic mean for the percentage of repeatability conducted by the Trios scanner and the Easyshade device. There was no statistically significant comparison between the shade measurement devices (p > 0.05). At baseline, the repeatability for both the Trios intraoral scanner and the Vita Easyshade Compact device for artificial teeth in the shades A1 and A3 was 100%. After aging, the trueness recorded by the intraoral scanner and the Easyshade device for artificial teeth in the shade A1 was 80%. For Class V restoration with shade A1, the intraoral scanner recorded 80% trueness and the Easyshade device recorded 60% trueness at baseline. For shade A3, the intraoral scanner recorded 60% trueness and the Easyshade device recorded 60% trueness. Conclusions: The intraoral scanner and Easyshade device are reliable for baseline shade selection, but their accuracy decreases after aging, particularly for darker shades.

Background: The bonding protocol for lithium disilicate veneers in the esthetic zone plays a crucial role in modern dental restoration techniques, focusing on the replication of natural tooth properties and esthetics. This process involves several meticulous steps on both ceramic and tooth surfaces to optimize material performance and bond strength. Methods: The objective of this article is to provide an updated review of the literature on the clinical steps for bonding lithium disilicate veneers in the anterior dentition and to document a clinical case where these advanced restorative techniques were applied to treat a female patient seeking to improve her smile. A preliminary review was conducted on the existing literature regarding the clinical protocols for bonding lithium disilicate veneers in the esthetic zone. The main advantage of careful bonding procedures is that they maximize the full potential of the materials’ properties. Results: A review of the literature reveals some minor differences in cleaning the veneers prior to cementation and in the number of steps involved when combining certain materials in a single application process. However, well-executed bonding procedures, following the manufacturer’s recommendations, can maximize the adhesion between the ceramic and the tooth, allowing the restorations to meet the patient’s esthetic demands. Conclusions: Effective bonding of lithium disilicate veneers in the esthetic zone requires multiple treatments on both the ceramic and tooth surfaces. When procedures are followed carefully, long-term esthetic and functional outcomes can be achieved. It is essential that clinicians are familiar with these steps. Proper patient selection, thoughtful treatment planning, and methodical execution of the case can lead to highly esthetic results that satisfy the patient’s demands and ensure long-term success.

Background: Lithium disilicate ceramic veneers are considered the gold standard in aesthetic dentistry due to their translucency, strength, and adhesive bonding properties. This clinical case report details the aesthetic rehabilitation of a patient through the use of pressed lithium disilicate veneers, highlighting the treatment workflow, material selection rationale, and the long-term functional and aesthetic outcomes achieved. Methods: A review was conducted to evaluate the long-term success of lithium disilicate. A case study is presented that involves a 32-year-old female patient with anterior tooth discoloration, minor morphological discrepancies, and a desire for smile enhancement. A conservative approach using pressed lithium disilicate was chosen to restore harmony and enhance natural aesthetics. The treatment involved minimally invasive tooth preparation, digital smile design, and adhesive cementation using a total-etch technique with light-cured resin cement. High-resolution intra-oral and extra-oral photographs documented the case, capturing the preoperative, preparation, and final restoration stages. These images highlight shade matching, margin adaptation, and smile transformation after veneering. Results: Postoperative evaluation showed excellent aesthetic outcomes, color integration, and marginal adaptation, with the patient expressing high satisfaction. The veneers exhibited optimal translucency and strength, ensuring long-term durability. A one-year follow-up revealed no debonding, marginal discoloration, or surface degradation, confirming the clinical reliability of lithium disilicate veneers. Conclusions: Lithium disilicate provides predictability, durability, and high aesthetic results, making it an ideal choice for minimally invasive smile enhancement. The use of photographic documentation emphasizes the importance of case planning, precise preparation, and adhesive bonding for successful outcomes. Future research should focus on long-term survival rates and complication prevention to further refine material selection and bonding protocols.

Background: Immediate implant therapy is a highly effective solution for replacing non-restorable teeth, particularly in the esthetic zone, where achieving optimal results can be challenging. In this area, even small imperfections can significantly affect a patient’s satisfaction due to the high visibility of the teeth involved. This narrative review provides an overview of findings from case reports and systematic reviews that highlight the success of immediate implant therapy in the esthetic zone. Additionally, it includes a case illustration to emphasize how meticulous planning, combined with advanced techniques, can achieve successful outcomes. Methods: A comprehensive literature review was conducted to evaluate the effectiveness of immediate implant placement and loading for non-restorable teeth in the esthetic zone. Key factors identified for success include atraumatic tooth extraction, precise implant placement, and effective soft tissue management to achieve natural esthetics and long-term stability. To illustrate these principles, the review features a clinical case involving the replacement of a maxillary right central incisor rendered non-restorable due to trauma. Treatment incorporated advanced digital planning, atraumatic extraction, immediate implant placement, and provisionalization. The final restoration involved soft tissue contouring and ceramic veneers on adjacent teeth, enhancing the patient’s overall smile and confidence. Results: Evidence from the literature indicates that well-planned immediate implant therapy achieves high success rates and long-term stability. In the clinical case presented, the workflow met the patient’s esthetic and functional needs, resulting in a natural, harmonious smile, and improved patient satisfaction. Conclusions: Immediate implant therapy in the esthetic zone is highly effective when critical considerations—such as bone preservation, guided implant placement, soft tissue shaping, and appropriate restoration—are meticulously addressed. Advanced techniques and careful planning are essential for fulfilling both esthetic and functional patient needs, ultimately delivering predictable and successful outcomes.
