T-Post™ Root-Post System from Komet USA

Simplify a wide range of restorative procedures and enhance predictable outcomes

In the 90-year history of the global Komet® corporation, 1983 stands out as a banner year, thanks to the introduction of the company’s T-Post™ cylindrical root-post system. Created as a restorative option for partially destroyed, devitalized teeth as well as those with multiple roots, the T-Post root-post system ushered in the era of specialized instrument systems for the Germany-based manufacturer.

Diverse Options

Since that initial introduction 30 years ago, the T-Post line has evolved to include a full complement of root-post options for modern dentistry. Fabricated of pure titanium, T-Post root posts offer a combination of biocompatibility, strength, and longevity. The system greatly simplifies reconstruction procedures and enhances reliable restorative outcomes for a wide range of applications.

Posts are available in a variety of head designs in several different sizes and diameters, as well as four shank lengths (6, 7, 9, and 13 mm). Included in the system are the T-Post unit with a non-protruding cylindrical head for reconstruction of partially destroyed teeth or multi-rooted teeth; the T-Post X root post with a pronounced retention head—often referred to as a “Christmas tree” due to the “step-down” design on its coronal portion—to simplify the reconstruction of severely damaged teeth (Figure 1); and the T-Post X ELO post, which is specially designed for use on severely damaged teeth with long clinical crowns. Both the T-Post X and X ELO posts feature individually segmented heads to provide reliable, secure retention of restorative materials.

Each post in the system also is available in active (threaded) and passive versions to accommodate varying root requirements. The active post shank with self-cutting thread serves as an active anchor within the root canal. Specially designed for more fragile teeth, the passive post shank features ground, macro-retentive retention grooves and a sandblasted, micro-retentive surface. Continuous decompression grooves facilitate the evacuation of excessive cement.

Clinical Technique

No matter what clinical situation presents, the T-Post system facilitates systematic treatment thanks to its optimally matched components and different post configurations. The preparation procedure consists of three basic steps, and the necessary tools are included in the T-Post kit.

Following preoperative radiologic evaluation and reduction of the clinical crown, reaming is accomplished with a four-blade, Gates-tip combination drill. Alternatively, a two-bladed twist drill can be used for hard obturation material. Next, the central inlay cavity is prepared with a root facer. For the direct build-up, the canal is filled with cement, and the selected post is inserted with the placement tool. Upon completion of the procedure, the patient’s natural dentition has been saved and restored through a safe, predictable procedure.

A selection of new, streamlined post kits has recently been introduced, enabling practitioners to become acquainted with the company’s full range of posts (Figure 2). The convenient introductory T-Post kits are offered in both active and passive configurations. Each kit contains ten posts in two diameters and two lengths, along with matching instrumentation for simplified post placement.
