Join Dr. Ronaldo Hirata, an expert in dental aesthetics, as he unveils essential techniques for perfecting dental restorations. In this comprehensive session, you’ll learn about chromatic enamel application, bulk-fill techniques, adhesive strategies, and how to achieve seamless aesthetic results....

This study investigates the influence of different polishing protocols on the surface roughness of composite resins, including low- and high-viscosity resins. Two polishing systems were tested: Sof-Lex and Astropol. The results revealed that resin composition had a greater impact on roughness tha...

In this video, we explore the world of dental aesthetics, focusing on restorative materials such as composite resins and ceramics. Through clinical examples, we address the importance of treatment customization, the choice between conservative and invasive techniques, and challenges in adapting a...

Discover advanced restoration techniques using direct and universal composites. This video explores innovative solutions for effective dental treatments, covering everything from the conventional layering technique to the use of Bulk Fill composites. Learn how to optimize clinical time with fewer...

In this lecture for The International Congress on Adhesive Dentistry - Japan, Dr. Ronaldo Hirata, internationally recognized in aesthetic dentistry, dives into the evolution of restoration techniques, sharing stories and clinical cases spanning decades. He explores how dental practices have trans...

Theoretical class on polymerization shrinkage and C-factor control, using tomographic studies that measure the size of the shrinkage and where it occurs in different types of resin. Understand the problem of stress caused by shrinkage in restorations and how to avoid it using the layering method.

Protocol for freehand anterior restoration technique, without waxing, silicone barrier, or stratification. Use of modified isolation, sandblasting with aluminum oxide, and non-continuous use of the ultrapack #000 retraction cord. Use of transparent matrix for traction technique, finishing, and po...

Hands-on for class I restoration using Bulk Flow resin, which can be applied in a single layer of up to 4 millimeters, leaving about 1 to 2 mm for the final step: chromatic enamel. An even more simplified technique, without stratification. Use of pigment in cusp anatomy.

Continued clinical case - Class II restoration of elements 36 and 37: cavity prophylaxis to remove the smear layer (smear on) + selective enamel etching and self-etch adhesive. Flow resin was used as a liner. Anatomy of the cusps of element 36.

Understand the causes of enamel hypoplasia and how to solve it. Intervention: stain removal and beveling, isolation, total acid etching, and universal adhesive system. Finishing and polishing with texturization.

Hands-On Class I restoration with Bulk Flow resin, which can be placed in a single layer up to 4 millimeters, leaving about 2 to 3 mm for the final two steps: chromatic and achromatic enamel. Use of dye in the anatomy of the cusps.

Replacement of amalgam restoration, class I on element 37, using Bulk Fill Flowable resin increment technique. Step-by-step of isolation, preparation, prophylaxis, acid etching, adhesive system, up to 4mm increment of Bulk Fill, leaving 1.3mm for the final stage: chromatic enamel. Occlusal adjust...

Replacement of two unsatisfactory restorations on teeth 46 and 47. Absolute isolation, prophylaxis, selective enamel etching, universal adhesive system. Use of irregular Bulk Fill resin on both elements. Occlusal adjustment and polishing.

Class I restoration with Bulk Fill Restorative A2 resin on premolars. Advantages of using a single increment of this resin in medium to deep cavities, comparing two different Bulk resin brands. Anatomy of both elements.

Exchange of unsatisfactory restoration with Bulk Fill Flow resin. Marginal finishing with W&H piezo ultrasonic tip. Selective acid etching of enamel and self-etch adhesive system. You can use up to 4 mm layer of flowable resin. Learn the advantages and disadvantages of the technique. Occlusal adj...

Postoperative sensitivity: related to margins and enamel. The highest success rate in case longevity is achieved solely through the use of the adhesive system. Understand the causes of sensitivity, how to prevent it by following the correct operation protocol, and how to remedy it upon recognizin...

Learned adjustments from the previous class in a clinical case. Adjustment of the incisal edge, midline, and cervical view. Symmetry between the two central incisors. Mirror areas, ridges, and adjustment of the proximal contact.

Incisal edge adjustment, midline, and symmetry between the two central incisors. Mirror areas, edges, and adjustment of proximal contact.

Theoretical lesson sequence on dentin adhesion: adhesion to dentin. Characteristics of dentin formation and its behavior in contact with acid etching. Understand the pros and cons of the smear layer. Basic components of adhesives and their indications.
