TECHNOLOGY
Our advanced technology, your benefits
OUR ADVANCED TECHNOLOGY, YOUR BENEFITS
Most of the material’s favourable features – like its high mechanical strength, wear resistance, antagonist friendliness and natural aesthetics – are thanks to a proprietary manufacturing technology developed by our R&D team in Japan. The ultrafine particle fillers are coloured and surface-treated first. For KATANA AVENCIA Block 2 ML, differently shaded fillers are then placed in layers – the key to a seamless multi-layered structure with transitional changes in chroma and translucency. Finally, for the ML and HT variants, the ultrafine alumina and silica fillers are pressed into high-density blocks, uniformly impregnated with resin monomer and heat-polymerized for excellent mechanical properties and surface smoothness.
Mechanical properties
Flexural strength 231 MPa
Compressive strength 675 MPa
KATANA AVENCIA Block 2 is equipped with superior optical, mechanical and handling properties, many of which are thanks to an advanced manufacturing process developed by Kuraray Noritake Dental Inc. Especially the unique filler treatment and resin impregnation process are leading the way towards well balanced features.

A BIOMIMETIC APPROACH TO POST-ENDODONTIC RESTORATIVE TREATMENT
Case by Jotautas Kaktys, DDS
A biomimetic approach to post-endodontic restorative treatment
Case by Jotautas Kaktys, DDS
Post-endodontic restorative treatments can be quite challenging, mainly because so many decisions need to be made. It is up to the clinician to evaluate the structural condition of the tooth to decide whether a direct or indirect restoration should be selected, which cusps to overlay and which ones to keep, and whether a post or fiber placement is required. Depending on the amount and condition of remaining tooth structure, a direct or indirect restorative approach may be more adequate; while selecting the indirect approach means they have the choice between lots of different restorative materials and restoration designs.
A CASE AS AN EXAMPLE
At our &SMILE clinic in Kaunas, Lithuania, the main goal is always to preserve as much natural tooth structure as possible without compromising the longevity of the restoration. Consequently, we opt for the least invasive approach reasonable, thereby using materials that mimic the mechanical and optical properties of the natural dentition. In this context, hybrid ceramics such as KATANA™ AVENCIA™ Block 2 are often a valuable choice.
The following case is used as an example to demonstrate the biomimetic approach in a situation that required an endodontic revision followed by an indirect restoration of the tooth that had previously been restored with composite.
STRUCTURALLY COMPROMISED MOLAR RESTORATION
The patient came in for a regular routine checkup. A massive composite restoration on her maxillary right first molar (FDI notation: tooth #16) attracted our attention as it appeared to be structurally compromised: Clinical examination revealed some occlusal porosities along the restoration margin, as well as cracked and chipped areas (Fig. 1). The buccal margin was stained and leaky (Fig. 2), while on the palatal surface, some micro-cracks were visible in the surrounding tooth structure (Fig. 3).
Fig. 1. Initial clinical situation with a large composite restoration that shows porosities at the margin.
Fig. 2. Buccal surface of the first molar with a stained, leaky margin.
Fig. 3. Palatal surface with micro-cracked tooth structure.
As the tooth had been endodontically treated elsewhere several years ago, a radiograph was taken (Fig. 4). This radiograph revealed that the canals were not filled to the apices of the roots. However, as the patient showed no symptoms, the decision was made to go for an indirect restoration without any endodontic retreatment: Reasons to opt for an indirect restoration included the large size of the existing composite restoration and the compromised condition of the surrounding tooth structure. Cementing indirect restorations offers additional benefits of virtually no polymerization shrinkage as well as minimal stress to the remaining and already compromised tooth structure and results in better mechanical properties. The tooth shade was determined immediately: The adjacent premolar had a tooth shade resembling A3 in the middle third, while the occlusal third showed some whitish spots and appeared brighter, similar to A2 (Fig. 5). This information was recorded for the dental laboratory.

MINIMALLY INVASIVE CUSP COVERAGE
a cost-conscious, yet aesthetically pleasing approach
Minimally invasive cusp coverage: a cost-conscious, yet aesthetically pleasing approach
Case by Jotautas Kaktys, DDS
An endodontically treated, structurally compromised mandibular molar with recurrent failure of direct composite restorations presents both biomechanical and aesthetic challenges. In patients with parafunctional habits such as bruxism, excessive tensile forces further increase the risk of fracture. This case report describes a minimally invasive, cost-conscious approach using a CAD/CAM hybrid material (KATANA™ AVENCIA™ Block 2, Kuraray Noritake Dental Inc.) to restore function, strength, and aesthetics while preserving remaining tooth structure.
CASE EXAMPLE: INITIAL SITUATION
The patient presented with a structurally compromised mandibular first molar and reported repeated failure of composite restorations, as well as dissatisfaction with aesthetics (Figs. 1 to 3). Longevity, strength, and cost-effectiveness of the treatment were key concerns.
Clinical findings, including worn canines and multiple cervical lesions, indicated a bruxing patient with group guidance during lateral movements, leading to excessive tensile stress and increased fracture risk. An indirect restoration with cusp coverage was indicated. Due to financial limitations and uncertain endodontic prognosis, a CAD/CAM hybrid material KATANA AVENCIA Block 2 ML (Kuraray Noritake Dental Inc.) in the shade A3 (Fig. 4) was selected.

TOOTH PREPARATION AND IMMEDIATE DENTIN SEALING
Preparation was kept minimally invasive to preserve remaining tooth structure while creating space for adequate material thickness (~1.5 mm; Figs. 5 and 6). Weak cusps were reduced with minimal biological sacrifice.
After sandblasting and pre-treatment of the old composite and fiber post surfaces with silane, exposed dentin was sealed using CLEARFIL™ SE Protect and coated with CLEARFIL MAJESTY™ ES Flow (Low flowability, shade A3D; both Kuraray Noritake Dental Inc.; Figs. 7 and 8). Due to the presence of sclerotic dentin, we decided to reactivate the surface and use a two-step self-etch system instead of a universal adhesive. Resin coating was performed to protect the underlying tooth structure and mask discolouration.

DIGITAL WORKFLOW
The intraoral situation was digitised using an intraoral scanner (Figs. 9 to 11). This enabled efficient computer-aided design and manufacturing (exocad DentalCAD; Figs. 12 to 14). The occlusal design was adjusted to minimise tensile forces during lateral movements. The restoration was milled and required only minimal finishing and polishing (TWIST™ DIA for Composite, Kuraray Noritake Dental Inc.), which was quick and effective (Fig. 15).

Fig. 15. Polishing is accomplished in two to three minutes and leads to great results.
TRY-IN AND PLACEMENT
Tissues had healed nicely in the three weeks between impression taking and final restoration placement (Fig. 16). Try-in confirmed a perfect fit of the restoration. Optical integration was difficult to assess without try-in paste (Fig. 17), but the patient was happy anyway, so that it was decided to move on immediately.
Isolation was achieved using a retraction cord (size 00) and PTFE tape (Fig. 18). As the bonding substrate consisted mainly of enamel and composite, a universal adhesive CLEARFIL™ Universal Bond Quick was selected. It was applied after phosphoric acid etching and treated with a gentle stream of air until the adhesive layer was uniformly thin (no pooling) and the surface did no longer move. As some remaining exposed dentin was present, the adhesive was polymerised to stabilize the hybrid layer. The restoration was pretreated (sandblasting, cleaning, CLEARFIL CERAMIC PRIMER PLUS) and adhesively cemented using a light-curing resin cement system to provide for dependable bonding.

TREATMENT OUTCOME
While the soft tissues were still slightly retracted after treatment and the optical integration difficult to assess due to dehydrated tooth structure (Fig. 19), radiographic examination confirmed proper biological integration (Fig. 20) and the patient was satisfied immediately. When she returned for a check-up after six months, we saw healthy soft tissues, a great marginal seal and proper aesthetic integration (Fig. 21). The restoration margins blended in nicely, no signs of wear were detectable and polish retention was great (Fig. 22).

CONCLUSION
Minimally invasive cusp coverage with KATANA AVENCIA Block 2 offers a predictable and cost-effective solution for structurally compromised posterior teeth. This is because the production procedure involves fewer manual steps, such as characterisation and glazing, while completely eliminating the need for heat treatment. A high level of automation further supports this efficiency. Successful outcomes depend on preserving the remaining tooth structure, careful treatment planning, and adherence to the recommended adhesive protocols.
