INSPIRE Esthetic Provisional Composite

Resist fracture and wear with a stronger provisional material

In the restorative process, the provisional restoration plays a crucial role in avoiding sensitivity and infection and ensuring a stable position of the tooth by maintaining opposing and adjacent contacts, thereby avoiding tooth movement. At this temporization stage, an adverse outcome could mean an emergency visit to your office or a problematic appointment during the placement of the final prosthesis.1,2

Currently, bis-acrylic is the product of choice among provisional materials because of its low shrinkage, easy handling, and esthetic properties. Recently, Clinician’s Choice introduced INSPIRE Esthetic Provisional Composite, which demonstrates excellent flexural strength (105 MPa), impact strength (76 MPa), and diametral tensile strength (62 MPa), reducing the risk of breakage, especially at the margins, where most provisionals fail if the amount of reduction is not adequate.3

Wear of the proximal contacts of the provisional restoration is the main reason why the final restoration does not seat properly on the prepared tooth. The final result is a mesial or distal open contact. Also, occlusal wear of the provisional with resultant tooth movement is the main reason for “high” contacts. INSPIRE prevents this from occurring.

At the provisional stage, the selection of the temporary cement is crucial. The ideal temporary cement should present the following: easy removal of excess cement from around the margins, good marginal seal to help minimize sensitivity, good retention but easy removal of the temporary prosthesis, low solubility in oral fluids, and compatibility with provisional resin restorations, resin core materials, bonding agents, and permanent cements.4 Polycarboxylate temporary luting cements present low postoperative sensitivity, adequate retention, and easy clean up.5 Cling2 Resin Optimized Cement is an example of this category. 

Time and frustration can be avoided by using a provisional restorative material that not only resists premature fracture, but also resists wear. The combination of INSPIRE Esthetic Provisional Composite and Cling2 Provisional Cement will minimize these clinical challenges.
