Importance of CBCT diagnostics in dental implantology

ABSTRACT In today's world, the aesthetic demands of patients in dentistry are very high, followed by functional requirements. CBCT diagnostics facilitate the achievement of these goals. Modern dentistry involves replacing missing teeth with dental implants. In dental implantology, precise imaging techniques are essential to accurately capture the area where implants will be placed, in order to avoid damaging adjacent vital structures during surgery. Today, radiological analysis of CBCT scans is considered the best method of choice, or the gold standard, in the pre-implantation procedure. On CBCT scans, we can visualize the height, width, and density of the available bone for implant placement, the precise location of the maxillary sinus, mandibular canal, mental foramen, incisive canal, and diagnose certain present pathological changes.

EVOLUTION OF DENTIN ADHESIVES: LITERATURE REVIEW

The aesthetic demand has culminated in the improvement of restorative dentistry through new products, such as dentin adhesives, so commonly used in current restorative procedures. The quality of the bond between the restorative material and the dental substrate is essential for the longevity of the treatment; therefore, dentin adhesives with different compositions are commercialized, aiming to achieve ideal adhesion. The present study aimed to review the literature on the evolution of dentin adhesives, since research can bring to light innovations that overcome the limitations of contemporary adhesive systems. This article shows the evolution of dentin adhesive agents, their effectiveness and clinical relevance. Knowing new dentin adhesives, techniques and necessary care before and during the application of the chosen adhesive contributes to increasing the durability of adhesive restorations, in order to ensure satisfactory results in the bond between the resin and the dental substrate, avoiding the repetitive restorative cycle.

3D Printed Dual Reduction Guide: A Feasible Alternative for Conservative Gingivectomy and Minimally Invasive Preparation for Ceramic Veneers.

This case report describes a digital workflow for designing and 3D printing a guide with the dual purpose of gingivectomy and tooth preparation in the esthetic zone, to be followed by cementation of ceramic veneers under rubber dam isolation. The patient's primary concern was to improve her smile. After clinical evaluation, our recommendation was for a minimal gingivectomy to match the gingival zenith for both central incisors, to be followed by ceramic laminate veneers. A digitally designed and 3D printed guide was used for gingivectomy and tooth preparation for the ceramic veneers. Ceramic veneers were cemented under rubber dam isolation to maximize bonding properties. A single guide can be digitally designed and 3D printed to perform controlled gingivectomy and minimally invasive tooth preparations. The outcome of the gingivectomy improved the gingival architecture for central incisors, and the ceramic veneers fulfilled the patient's esthetic demands.

Dermal Regeneration Template Generated Skin Can Be Raised as A Flap: A New Dimension in Aesthetic Restoration

AbstractChildhood scars can lead to hideous aesthetic and functional deformities in young adults, which can be particularly distressing when involving the face and the breast in a female. Aesthetic restoration requires replacement of the whole or a part of the scarred skin by soft, pliable, and texture-matching skin, which nearly always is in short supply. Dermal regeneration templates (DRTs) can help in skin regeneration that is almost always aesthetically superior to most flaps. Aesthetic demands at the time of final restoration may require the regenerated skin to be moved as a local flap. As regenerated skin from dermal templates is known to match the vascularity of normal native skin, raising it as a flap should follow logically. This, however, has never been attempted to the best of our knowledge after a thorough literature search. We report a case of successfully using DRT-generated skin raised as a flap for aesthetic reconstruction of a postburn scarred breast in a young female. This adds a whole new dimension to the use of DRTs and points to a new field of research in scar management and aesthetic restoration.

Progress and Current Status of Treatment for Lower Limb Varicose Veins

Varicose veins of lower extremities are common venous diseases of lower extremities in clinic [1]. The total number of patients with varicose veins of lower extremities in China has exceeded 100 million, and the incidence rate is about 15% [2]. Therefore, there is a huge number of illnesses and a demand for surgical treatment. At present, the main treatment options for lower limb varicose veins include conservative treatment and surgical treatment. Surgical treatment methods include traditional surgery and minimally invasive surgery. The high ligation and stripping of the great saphenous vein has always been the gold standard for the treatment of lower limb varicose veins. This method is technically mature and clinically effective, but it is a destructive surgery that uses a stripping device to forcefully pull. Therefore, the intraoperative trauma is large, the amount of bleeding is high, and a series of postoperative complications such as hidden nerve damage, subcutaneous congestion, incision bleeding, deep vein thrombosis, etc. are prone to occur. With the increasing demand for skin aesthetics and reducing postoperative complications, minimally invasive surgery has gradually been applied to the treatment of lower limb varicose veins, such as intracavitary laser ablation, intracavitary radiofrequency ablation, Tri Vex minimally invasive rotary cutting, hemodynamic correction, etc. [3]. This article provides a review of the current main treatment methods for lower limb varicose veins, in order to further understand and master the principles and application scope of each treatment method, and to better select personalized treatment plans for varicose vein patients in the future.

Chameleon‐Inspired, Dipole Moment‐Increasing, Fire‐Retardant Strategies Toward Promoting the Practical Application of Radiative Cooling Materials

AbstractToward addressing the aesthetic demand, IR emissivity, and fire hazards of radiative cooling materials in the practical application, chameleon‐inspired is tactfully employed, dipole moment‐increasing, and fire‐retardant strategies to manufacture an advanced polyurea‐based composite coating through incorporating thermochromic microcapsules, boron nitride nanosheets, and montmorillonite nanosheets. The chameleon‐inspired thermochromic microcapsules and admirable IR emissivity (supported by the original IR emittance spectra) realized by the increasing dipole moment allow the composite coatings to spontaneously adjust the solar absorption and reflection during hot daytime, while enabling high‐efficiency radiative cooling throughout the day. The IR emissivity higher than most literature is attributed to the strong interfacial interactions within polyurea composite coatings which improve the dipole moment of C─O─C, Si─O, and B─N bonds by increasing the distance between the centers of positive and negative charges, thus producing more IR emissions. Furthermore, the thermally melted montmorillonite nanosheets can form a ceramic protective layer enhanced by boron nitride nanosheets, further suppressing combustion behavior to improve the fire safety performance of polyurea coatings. The integration of thermochromic functionality, high fire safety, and admirable IR emissivity not only contribute to promoting the practical application of radiative cooling materials, but also provide a precious reference route to design high IR emissivity.

Unpacking Mobile Website Aesthetics and Its Effect: A Case of M-commerce Website Offering Search and Experience Goods

ABSTRACT A major challenge for mobile commerce operators is how to attract customers to access their websites displayed on a mobile device screen only twice the size of a palm, so making design of such websites is especially important in order to catch customers’ eyes. Based on S-O-R model, the study developed a research model to explain how aesthetics of m-commerce websites affects customers’ continuing access to the websites. The model was evaluated through a stratified survey of 285 participants on m-commerce websites with varying levels of mobile website aesthetics. Structural equation modeling (SEM) was utilized to analyze the data. The results uphold the applicability of visual aesthetics (VisAWI) scale in m-commerce, which has significant positive effect on websites’ perceived usability. The study also finds that mobile websites selling experience goods have higher demand for website aesthetics than those for search goods. The study offers a well-structured practical instrument based on visual aesthetics (VisAWI) scale, helping mobile website designers understand the effect of specific aesthetic elements on user behavioral intention.

In Vitro Fracture Strength of Primary Canine Teeth Reinforced With Prefabricated and Customized Fiber-Reinforced Post Systems.

The demand for esthetics has increased in today's worldand most parents prefer to preserve their children's primary anterior teeth until their natural exfoliation. However, an intracanal post is required to provide retention for reconstruction of severely damaged anterior teeth due to caries or trauma. Various materials and methods may be used for the fabrication of intracanal posts. This study assessed the fracture strength and fracture mode of primary canine teeth reconstructed with prefabricated and customized polyethylene and glass fiber posts. This in vitro study evaluated 60 extracted primary canine teeth in four groups (n = 15). After pulpectomy and post space preparation with 4 mm depth, composite resin post, prefabricated glass fiber post (Whitepost), customized glass fiber post (Interlig), or customized polyethylene fiber post (Ribbond) were placed in the root canals to provide retention, and the tooth crown was restored with bulk-fill composite resin. The fracture strength was then measured in a universal testing machine. The fracture mode was also evaluated visually. The mean fracture strength was 22.45 ± 5.06, 33.10 ± 8.5, 30.20 ± 7.33, and 32.61 ± 5.73 N/mm2 in the composite resin post, Whitepost, Interlig, and Ribbond groups, respectively. The fracture strength was significantly lower in the composite group than in the remaining three groups (p = 0.000). No other significant differences were found (p > 0.05).Also, no significant difference was observed among the study groups in the fracture mode (p = 0.241). The composite resin post yielded a significantly lower fracture strength than the prefabricated and customized glass and polyethylene fiber posts, but the fracture mode was not significantly different among the four groups.

The effectiveness of direct versus indirect restoration techniques following canal therapy

The restoration of endodontically treated teeth is a critical aspect of dental practice, with the choice between direct and indirect restoration techniques being central to optimizing clinical outcomes. Direct restorations, such as composite resins, offer advantages in terms of cost, time efficiency, and preservation of tooth structure. However, their long-term performance, particularly in posterior teeth, may be compromised by issues such as marginal leakage, wear, and discoloration. Indirect restorations, including crowns, onlays, and inlays, provide enhanced durability, fracture resistance, and aesthetic outcomes, particularly for teeth that have undergone significant structural loss. These restorations, often made from ceramics or metals, offer superior longevity but come with higher costs and longer treatment times. The aesthetic performance of restorations plays a significant role in patient satisfaction. While direct restorations allow for immediate aesthetic adjustments and are generally more affordable, they may suffer from discoloration and wear over time. Indirect restorations, particularly porcelain-based options, offer better color stability and natural appearance, making them a preferred choice for patients with high aesthetic demands. Cost-effectiveness is another critical factor influencing clinical decision-making. While direct restorations are more affordable initially, their long-term cost-effectiveness may be compromised by the need for repairs or replacements. Indirect restorations, despite their higher upfront cost, often prove to be more economical in the long run due to their durability and reduced need for maintenance. The decision between direct and indirect restoration techniques should be individualized, considering factors such as tooth location, the extent of damage, aesthetic requirements, and financial constraints. A comprehensive evaluation of these factors, along with clear communication with the patient, is essential for achieving optimal clinical outcomes. Indirect restorations generally offer better long-term performance, particularly for heavily compromised teeth, while direct restorations remain a viable option for cases where cost and time efficiency are prioritized.

Colored Radiative Cooling and Flame-Retardant Polyurethane-Based Coatings: Selective Absorption/Reflection in Solar Waveband.

The aesthetic demand has become an imperative challenge to advance the practical and commercial application of daytime radiative cooling technology toward mitigating climate change. Meanwhile, the application of radiative cooling materials usually focuses on the building surface, related tightly to fire safety. Herein, the absorption and reflection spectra of organic and inorganic colorants are first compared in solar waveband, finding that iron oxides have higher reflectivity in NIR region. Second, three kinds of iron oxides-based colorants are selected to combine porous structure and silicon-modified ammonium polyphosphate (Si-APP) to engineer colored polyurethane-based (PU) coating, thus enhancing the reflectivity and flame retardancy. Together with reflectivity of more than 90% in near-infrared waveband and infrared emissivity of ≈91%, average temperature drops of ≈5.7, ≈7.9, and ≈3.8°C are achieved in porous PU/Fe2O3/Si-APP, porous PU/Fe2O3·H2O/Si-APP, and porous PU/Fe3O4·H2O/Si-APP, compared with dense control samples. The catalysis effect of iron oxides in the cross-linking reaction of pyrolysis products and dehydration mechanism of Si-APP enable PU coating to produce an intumescent and protective char residue. Consequently, PU composite coatings demonstrate desirable fire safety. The ingenious choice of colorants effectively minimizes the solar heating effect and trades off the daytime radiative cooling and aesthetic appearance requirement.

Zirconia Implants: A Brief Review and Surface Analysis of a Lost Implant

Zirconia implants have emerged as a valuable alternative for clinical scenarios where aesthetic demands are high, as well as in cases of hypersensitivity to titanium or for patients who refuse metallic objects in their bodies due to personal reasons. However, these implants have undergone various changes in geometry, manufacturing techniques, and surface modifications since the introduction of the first zirconia implants. The present study aims to review the current evidence on zirconia implants, considering the changes they have undergone in recent years. Additionally, it aims to analyze the three-dimensional surface characteristics of a failed zirconia implant using scanning electron microscopy and elemental analysis with energy-dispersive X-ray spectrometry (EDX). A zirconia implant lost three weeks after placement was immediately assessed using VP-SEM equipment and chemically analyzed by EDX using a 410-M detector connected to the microscope. Sparse material depositions were found on all parts of the implant, with a notable concentration in the thread grooves. The elements identified in the sample included zirconium, oxygen, carbon, calcium, and phosphorus. This report demonstrates that the surface of zirconia implants can accumulate elements early in the process of bone matrix neoformation, which is consistent with the initial stage of osseointegration.

Advanced Material Strategy for Restoring Damaged Endodontically Treated Teeth: A Comprehensive Review.

The restoration of endodontically treated teeth (ETT) remains a significant challenge in modern dentistry. These teeth often suffer from substantial structural damage due to both the original pathology and the invasive nature of endodontic procedures. Consequently, ETT are more susceptible to fractures compared to vital teeth, necessitating restorative strategies that can effectively restore both function and aesthetics while minimizing the risk of failure. In recent years, advances in adhesive dentistry and the development of high-strength ceramics have further expanded the restorative options for ETT. Bonded restorations have gained popularity as they preserve more tooth structure and enhance the overall strenght of the tooth-restoration complex. The choice of restorative material and technique is influenced by numerous factors, including the amount of remaining tooth structure, the functional requirements of the tooth, and the aesthetic demands of the patient. Despite the plethora of available materials and techniques, the optimal approach to restoring ETT remains a topic of ongoing research and debate. In this comprehensive review, the current state of and recent advances in restoring damaged endodontically treated teeth are explored. Numerous therapeutic options exist, involving a wide range of materials. This article aims to present the biomaterial advancements of the past decade and their applications, offering alternative approaches to treating damaged ETT with the goal of prolonging their retention on the dental arch and serving as a valuable resource for dental practitioners who face this issue daily.

Effects of Internal Bleaching on Microtensile Bond Strength of a Former Veneer Composite to Tooth Enamel

Background: At present, combined provision of direct composite restorations and dental bleaching has become increasingly popular to meet the esthetic demands of patients. This study aimed to assess the effect of internal bleaching on microtensile bond strength of composite to freshly veneered enamel. Methods: In this in vitro experimental study, 50 sound extracted human premolars were randomly divided into five groups (n=10). All teeth received composite veneers. Two groups underwent no further intervention and were subjected to measurement of microtensile bond strength of composite to enamel 24 hr and one week after the veneering. The remaining three groups underwent internal bleaching. Group 3 underwent bleaching one month after the veneering, and microtensile bond strength was measured after 24 hr. In groups 4 and 5, bleaching was performed immediately after the veneering. Microtensile bond strength was measured after 24 hr in group 4 and after one month in group 5. Data were analyzed using one-way ANOVA. Results: All the groups were not significantly different regarding the mean bond strength (p=0.110), but they were significantly different in terms of the mode of failure (p=0.01) such that the mode of failure was mainly adhesive in the three bleached groups. Conclusion: Internal bleaching after composite veneering has no significant effect on microtensile bond strength of composite to the enamel.

Digital resources for surgical and restorative treatment of excessive gingival display in one session.

This article aims to showcase the implementation of a digital workflow in addressing a case of multifactorial excessive gingival display in a patient with high esthetic demands, incorporating both surgical and restorative interventions in a single session. A 28-year-old female patient presented with excessive gingival display, attributed to a combination of short teeth due to altered passive eruption, lip hyperactivity, and a sub-nasal depression that lodged the upper lip during spontaneous smiling. The multidisciplinary treatment strategy encompassed surgical crown lengthening, the placement of a biovolume in the maxillary concavity, and the rehabilitation of the six anterior teeth with direct composite resin, all done in a single session. Smilecloud Biometrics was used to digitally plan the smile, and the final wax-up/mock-up was approved by the patient prior to any irreversible procedure. A digital planning center (GuiderLab) enabled the materialization of the virtual planning and the printing of the periodontal surgical guide, the biovolume, and the resin layering guides for the restorative technique. Adopting a digital workflow in multidisciplinary cases with excessive gingival display leads to predictable and more expedited outcomes, ensuring a favorable result between soft and hard tissues. Excessive gingival display is a condition with multifactorial etiologies, including dentoalveolar, periodontal, skeletal, or muscular origins, or a combination of these factors. The diagnoses of altered passive eruption and a hypermobile upper lip are common in daily clinical practice and can be successfully managed through surgical crown lengthening and filling of the maxillary concavity, respectively. To achieve the desired outcome, restorative procedures often complement these surgical interventions.
