Ultimate ceramic veneer: a laboratory-guided preparation technique for minimally invasive laminate veneers [Case Report]

De Andrade, Oswaldo Scopin; Hirata, Ronaldo; Celestrino, Marcos; Seto, Marcio; Siqueira, Sergio Jr; Nahas, Rodrigo
Clinical success of ceramic laminate veneers depends on material selection, bonding procedures, controlled laboratory steps, and enamel preservation. Enamel preservation is the most critical because excessive tooth preparation can expose dentin reducing bond strength, which is a factor that can cause a decrease in long-term clinical success. The proposed technique based on carefully treatment planning developed between clinician and dental technician helps to maximize enamel preservation, which is an important element for clinical success.

Association of enamel microabrasion and bleaching: a case report [Case Report]

Higashi, Cristian; Dall'Agnol, Ariane Lima; Hirata, Ronaldo; Loguercio, Alessandro Dourado; Reis, Alessandra
Enamel microabrasion may be indicated for certain clinical situations, since it is a proven method for removing superficial intrinsic enamel discoloration defects such as fluorosis-like stains; in addition, it is safe, conservative, and easy to perform. However, this method removes enamel structure, causing teeth to become yellowish. This yellowing can be treated with enamel microabrasion and bleaching. This article describes and documents how these two methods were utilized to correct tooth color for a young patient.

All-ceramic inlay-retained fixed partial bridge using a CAD-CAM produced Y-TZP framework and fluoroapatite veneering ceramic: a clinical report [Case Report]

Hirata, Ronaldo; Viotti, Ronaldo; Reis, Andre Figueiredo; de Andrade, Oswaldo Scopin
All-ceramic materials have become an excellent option for both anterior and posterior fixed partial dentures (FPDs) due to advances in esthetic and mechanical properties. This clinical report describes the use of an all-ceramic inlay-retained three-unit FPD for replacement of a maxillary second premolar. Prosthetic restorative materials consisted of a CAD-CAM processed presintered yttrium stabilized zirconium oxide (Y-TZP) framework and a fluoroapatite veneering ceramic. The minimally invasive preparation technique and advantages of this highly esthetic and resistant treatment option are discussed.
