The dental core build-up material market is a relatively small segment compared to restoratives or bonding agents because the core build-up step is not required at every indirect restoration procedure. A core build-up is a restoration placed on a severely damaged tooth in order to restore the bulk of the coronal portion of the tooth. The core is defined to be part of the preparation of an indirect restoration consisting of restorative material. The material is only necessary in cases where there is extensive damage done by tooth decay or after a root canal. Root canals tend to make teeth more susceptible to fractures. Therefore, positioning a crown after a root canal usually requires core build-up.
Dental impression materials are used to take an impression of the hard and the soft tissue in the intraoral cavity. They are then sent to the dental laboratory to be used in the production of prosthetics. In essence, they are an imprint of the teeth structure and the soft tissue surrounding it. The conventional method of taking an impression involves placing the material on the teeth to produce a cast. The type of material used in this process matters significantly, as it has to represent the actual teeth structure accurately and should remain stable until the production of the restoration.
Direct restorative materials, more commonly known as fillings, are dental materials that are positioned directly onto a tooth at the dental clinic. Direct restorations are distinct from indirect restorations in that they are produced inside the mouth by the dentist, and not in a dental laboratory, through the assistance of dental impressions. Consequently, they only require a single visit to the dentist, during which the filling material is shaped by the dentist before it hardens and takes its final shape in the intraoral cavity.
Temporization in dentistry refers to the placement of temporary prosthetics in the patients mouth until the permanent crown, bridge or implant is ready to be planted. The large majority of temporary restoratives use composite resin and acrylic as their base material. Composites are biocompatible, aesthetically pleasing and quick to place in the intraoral cavity. However, they can exhibit surface hardness and are more expensive than acrylic products.
The U.S. market for dental materials includes dental cements, impression materials, direct restoratives, temporary restoratives, bonding agents, core build-up materials and anesthetic materials. The overall U.S. dental material market is projected to experience modest growth over the forecast period, largely limited by the emergence of intraoral scanners. Although digitization is yet to become widespread, it has already impacted the dental material market, particularly towards impression and temporary restorative materials. As digital impression taking scanners are becoming more affordable and popular, the need for dental impression and temporary restorative materials is dwindling. Despite the gradual digitization of dental offices, this trend will still put short term pressure on both the prices and unit sales.
