Impression materials, in the fluid or plastic state, are carried to the mouth in a suitably sized tray. Hardening of the material takes place either on cooling or through a chemical reaction. There is no clear line between mucostatic and mucodisplacing impression materials. Mucodisplacive : compound, high viscosity alginates, high viscosity elastomers. These viscous impressions materials are called mucocodisplacive impression materials. These record an impression of the mucosa under load. This results in a wider distribution of load during function, making it more stable it also compensates for the differing compressibility of the denture bearing area reducing the risk of a fracture due to flexion. However the retention of the dentures may be compromised as the soft tissues wish to return to their original position at rest. The download-able presentation is below.

Impression materials are used to record the shape of the teeth and alveolar ridges. There are a wide variety of impression materials available each with their own properties, advantages and disadvantages. Materials in common use can be classified as elastic or non-elastic according to the ability of the set material to be withdrawn over undercuts.

Bonding part one is already posted, so this part was named bonding part two. Agaiiiin! It is about bonding, guys! Without wasting time, let's get kicking, everyone! The download-able presentation is below. Bonding 2 05

This material has linkage with bonding. Or in other way of say, adhesion is interrelated with bonding and vice versa. Adhesive dentistry is a branch of dentistry which mainly deals with adhesion or bonding of the adhesive material or cements to the natural substance of teeth, enamel and dentin. Bonding techniques have various clinical applications including operative and preventive dentistry as well as encompasses numerous areas and products. Let's start with creating the ultimate hybrid layer. The hybrid layer is very important and can be the reason a composite restoration is a success, or a failure. This layer is the bond between the tooth structure and the filling material; composite. The download-able presentation is below. bioadhesi s1 Hope it help as well.

Konnichiwa, minna-san. How's life? Mine's good. I am going to have Japanese Language Proficiency Test this end of year. In Japanese it is Nihongo Noryoku Shiken. I actually want to participate last year, but I was late. Moreover, my friends were entrusted my to enrole the examination, but I was forget the due date. I was near-to-do harakiri :D for my apology. Anyway, I hope it will go well this year. Wish me luck! And here we go again. Dental amalgam is the most commonly used dental restorative material used for dental fillings. First introduced in France in the early 19th century, it contains a mixture of mercury with at least one other metal. Amalgam has been the restorative method of choice for many years due to its low cost, ease of application, strength, durability, and bacteriostatic effects. Factors that have led to recent decline in use are a lingering concern about detrimental health effects, aesthetics, and environmental pollution. The aesthetic issue is becaus...
