Federico Ferraris Adhesthetics Theca Kit

The Adhesthetics Theca kit is comprised of four unique instruments designed by Dr. Federico Ferraris in collaboration with Hu-Friedy. It is a unique set of instruments created for use during the clinical phases of both direct and indirect restorative dentistry to help clinicians achieve positive results through clinical excellence.

The Main Shaper, the Fine Shaper, the 3D Shaper and the Direct Caliper are all made using XTS technology, a dark Aluminum Titanium Nitride (AlTiN) coating that offers superb contrast in comparison to composite materials and tooth structure.

The coating is also incredibly slick, resisting the adhesion of sticky composite materials. The smooth handle is not only ergonomic and lightweight, but each instrument has its own distinct set of colour cones, making instrument identification simple. The set of four instruments includes an IMS Cassette, which prevents the instruments from being damaged during transportation and sterilization protocols.

Manipulation of composite on buccal surfaces during direct anterior restorations, Class IV and V cases, direct veneers restorations and general esthetic restorations. The tip’s lance shape and flexibility allow for it to adapt to restorative material and is also effective in removing excess material from the vestibular region by using its edge (Fig. 7). Its flexibility allows for restorative materials to be manipulated with a delicate touch. It is sturdier than a standard brush however less rigid than a standard spatula.

Application of medium-great quantity of material directly on the tooth or as a material carrier. Its round shape and rigidity allow for the manipulation of restorative materials in wide cavities. It is also effective when placing material on wide surfaces (Fig. 8). Dimensions of working part: length 11,5 mm; width 2,5 mm and thickness 0,4mm.

TNFF3/4 Fine Shaper /Cord Packer
Modelling of restorative materials on anterior and posterior teeth as well as the placement of retraction cord. A distinctive characteristic of this spatula (FF3 straight and FF4 angled) is its flexibility. Its thin design allows for precise modelling (Fig. 9, 12).

It is particularly useful for deep cavities. It is also helpful during procedures where high magnification is used because its length allows for easier access to these deep regions while not interfering with the clinician’s field of vision. Retraction cord can be placed precisely with the thin instrument tip (Fig. 14).

TNFF5/6 3D Shaper
Anatomical modelling of restorations of posterior cusps (Fig. 17) or of anatomical dentinal or superficial elements on anterior teeth. The unique teardrop shape of this point makes it excellent for sculpting materials in both posterior and anterior cases.

Sculpting thin sulcus as well as finishing of the margins and thin modellings on posterior and anterior direct restorations. Application of fluid material in deep cavities (Fig. 23), positioning of flowable materials in occlusal sulcus, coating low viscosity materials, removal of excesses of high viscosity cementation material and control of margins after cementation (Fig. 27) point makes it excellent for sculpting materials in both posterior and anterior cases. 

Its distinctive curved shape allows the tip to easily reach areas in both the anterior and posterior arch. Fine details can be created in restorative materials due to the tip’s thin design.

TNFF7/8 Direct Caliper
Measuring thickness of enamel margin in direct restorations on anterior teeth, measuring thicknesses of direct and indirect restorations during various clinical phases (Fig. 29), creating definition of dentinal curving (Fig. 30).

This instrument is a restorative probe with a flat head (not rounded, as most periodontal probes) with grooves at 0.5mm increments. The tip is angled at 45° which when aligned against the preparation bevel, allows for the thickness of dentinal material and residual buccal enamel to be determined.

The FF7 can be used to assess an enamel thickness of 0.5mm (the universal thickness in the third medium of the crown), while the FF8 can be used to assess a thickness of 0.9mm (which is preferred in incisal areas, or times when the thickness of the natural enamel is of critical importance). The shape of the dentin in the incisal direction in addition to the thickness to the margin can be determined with this instrument.
