Digital Workflow for Indirect Bonding with 2D Lingual Brackets: A Case Report and Procedure Description.

Objective: During orthodontic therapy, accuracy in bonding procedures makes it easier to correct tooth alignment by decreasing the need for midcourse corrections by changing bracket positions. Indirect bonding allows the transfer of the appliance components from model casts to patient's teeth potentially meaning shorter appointments for bracket bonding and rebonding and best comfort during chairside practice. At the same time, there has been a steady increase in requests for invisible lingual orthodontic treatment.

Adhesion of Streptococcus mutans to different restorative materials.

Adherence of oral bacteria to the surface of dental restorative materials is considered an important step in the development of secondary caries and periodontal disease. The aim of this study was to investigate and compare the adherence of different restorative materials to Streptococcus mutans strain (CCUG35176) in order to ascertain possible differences. The materials tested ranged across different classes including: flowable composites (Gradia Direct LoFlo; Filtek Supreme XT Flowable), anterior composites (Gradia Direct Anterior), universal composites (Filtek Supreme XT), packable composites (Filtek Silorane; Filtek P60), glass-ionomers (Fuji IX Gp Extra; Equia) and a control reference material (Thermanox plastic coverlips).
