DigiSplint nightguard being printed on EnvisionONE 3D printer
Leinfelder Wear Simulator was used to simulate the wear in vitro KeySplint Soft™ when stored at 37°C for 24 hours followed by placement in PMMA beads slurry and then exposed to localized wear using stainless steel. Volume loss(mm3) and maximum depth (μ) was calculated after 400,000 cycles which is said to be equal to 3 years of clinical wear.
Wear conditions in removable dental appliances can be categorized into generalized and localized conditions, where wear due to the masticatory forces is said to be generalized and direct tooth to material contact is localized. This study indicates that KeySplint Soft™ material wears less in both conditions in vitro.
KeySplint Soft™ changes its properties with temperature and thus becomes more pliable when in contact with the body temperature, reducing the chances of fracture. KeySplint Soft does not show any cracking on magnification, thus suggesting energy absorbing behavior. Furthermore, this material when subjected to continuous temperature change intraorally and at room temperature enhances the longevity of the appliance.
When DigiSplint is warmed up under hot water it becomes flexible.

It has been eight years since Dr. Fritz and his team published the Supportive Periodontal Implant Maintenance Protocol, which has been shared and implemented in dental practices and hygiene colleges across the globe. With the exciting new periodontal and peri-implant classifications published simultaneously by the AAP and EFP they felt it was necessary to revisit the implant maintenance protocol to better reflect the new information and technologies available today. This lecture is focused on the best evidence to prevent peri-implant mucositis and peri-implantitis using a systematic approach which is personalized for the patient. This critical update has eliminated several steps from the former algorithm and replaced them with innovative approaches generated from new concepts of peri-implant health.
Define and identify peri-implant health, peri-implant mucositis, and peri-implantitis based on the new periodontal and peri-implant classification system (2018).

Lava Esthetic zirconia is a CAD/CAM disc for dental lab fabrication of esthetic all-ceramic full-contour restorations. It is a pre-shaded, high translucent cubic zirconia material with a natural color gradient optimized for esthetic full-contour restorations.
What is cubic zirconia?
A new all-ceramic material class based on zirconia. Compared to conventional zirconia, cubic zirconia offers a significantly higher translucency at a reduced strength level. Cubic specifies the dominant crystal structure present in Lava Esthetic zirconia. In conventional zirconia products like 3M™ Lava™ Plus Zirconia, the tetragonal crystal structure is dominant.
How does the composition of Lava Esthetic zirconia compare to Lava Plus zirconia?
Both are “polycrystalline” materials, this means that they consist of many small crystals. The crystals are composed of zirconium dioxide (syn. zirconia) with a small addition of yttrium oxide (syn. yttria) (3 mol%– 5 mol%). The yttria content determines the so-called “phase or structure” of the crystals, i.e. how the Zr and O atoms are arranged in the crystal lattice. Zirconia has three distinct phases: monoclinic, tetragonal and cubic. Conventional zirconia such as Lava Plus zirconia contains around 3 mol% yttria and the crystal phase is predominantely tetragonal. Under mechanical stress the crystals can undergo a phase transformation to monoclinic. This leads to a local volume increase that impedes crack propagation and makes conventional zirconia the strongest and toughest ceramic used in dentistry. Lava Esthetic zirconia contains 5% mol, the crystal phase is predominantely cubic. Cubic grains are larger and have isotropic (same in all directions) optical properties. This leads to less scattering of light and therefore greatly improved translucency.
What is the main difference between Lava Esthetic zirconia and other cubic zirconia?
The Lava Esthetic zirconia discs are gradient pre-shaded with a new proprietary shading chemistry with four shading elements. This enables a true color match to VITAclassical shades and makes Lava Esthetic zirconia the first zirconia with inherent tooth-like fluorescence built into the disc.
What is tooth-like fluorescence and why does it matter?
Sunlight and artificial light contain invisible ultra-violet (UV) light. Natural teeth look blue in UV light because they absorb UV light and emit visible blue light. This is called fluorescence. To look natural in all light conditions restorative materials have to mimic this effect.
How can I achieve the best final shade match?
Lava Esthetic zirconia offers a built-in shade gradient and inherent fluorescence for a true match to VITA classical shades. Glaze restorations to achieve best match to selected shade. Lava Esthetic zirconia has a high translucency so that dark preparations may shine through. Communicate the stump shade to your lab to ensure shade match.
Will Lava Esthetic zirconia replace any of the current Lava zirconia products?
No, Lava Esthetic zirconia comes in addition to the current portfolio. It is a new type of zirconia for productive high-esthetic full-contour restorations. Lava Plus zirconia remains our versatile high strength zirconia option.
What is the strength of Lava Esthetic zirconia?
Lava Esthetic zirconia offers a 3-point bending strength according to ISO 6872:2015 of 800 MPa and is qualified for Type II, class 4 indications: Crowns, bridges with one pontic between two crowns, inlays, onlays and veneers. Lava Esthetic zirconia has a significantly higher flexural strength than IPS e.max® CAD. Lava Esthetic zirconia has higher flexural strength than other leading super-high translucent cubic zirconia, but less than Lava Plus zirconia.
What is the fracture toughness of Lava Esthetic zirconia?
Lava Esthetic zirconia has a fracture toughness of 4.4 ± 0.5 MPam½ measured by the SEVNB method according to ISO 6872:2008. And, it has a significantly higher fracture toughness than IPS e.max CAD.
What indications can be covered with Lava Esthetic zirconia?
• Bridges (max. 1 pontic between two crowns)
• Inlays, onlays, veneers
Please refer to Instructions for Use for details.

Can Lava Esthetic zirconia restorations be used on implants?
Yes, Lava Esthetic zirconia crowns and bridges (with max. 1 pontic between two crowns) can be used on implant abutments.
Can Lava Esthetic zirconia be used for adhesive bridges such as Maryland bridges or inlay/onlay bridges?
No, Lava Esthetic zirconia is released for bridges with maximum 1 pontic between two full coverage crowns.
Can Lava Esthetic zirconia be used for cantilever bridges?
No, Lava Esthetic zirconia is released for bridges with maximum 1 pontic between two full coverage crowns.
Can bruxism patients use Lava Esthetic zirconia?
For cases with very limited space or parafunctional patients requiring ultimate strength, choose Lava Plus zirconia.
In what shades is Lava Esthetic zirconia available?
There are eight shades available at launch: Bleach, A1, A2, A3, A3.5, B1, C1, D2. Additional shades are under development and will be available in 2017.
Is a white Lava Esthetic zirconia disc for liquid shading available?
No. There are no white discs and no liquids available. All Lava Esthetic zirconia discs are pre-shaded and must not be used in combination with liquids.
In what formats is Lava Esthetic zirconia available?
Lava Esthetic zirconia is available in 98 mm disc format with step in three heights: 14, 18 and 22 mm.
Is Lava Esthetic zirconia available on a CEREC® mandrel?
No, Lava Esthetic zirconia is available in 98 mm disc format with step.
Is Lava Esthetic zirconia available in frame format?
No, Lava Esthetic zirconia is available in 98 mm disc format with step.
Which milling systems are compatible with Lava Esthetic zirconia discs?
Lava Esthetic zirconia discs fit into open milling machines compatible with 98 mm disc format with step suitable for dry milling of zirconia, e.g.:
• Roland DWX-50, DWX-51D
• Sirona InLab MC X5
• VHF K3, K4, K5, S1, S2
• imes-icore CoRiTEC 245i, 250i, 350i, 650i, 850i
• Yenadent D14, D15, D40, DC40, D43
This list is for guidance purposes only – many other compatible milling systems exist and new systems enter the market frequently. Always check with milling system suppliers for compatibility. Lava Esthetic zirconia discs are not compatible with Zirkonzahn Mx, Sirona Inlab/CEREC MC XL, 3M™ Lava™ Form and 3M™ Lava™ CNC milling systems.
How should Lava Esthetic zirconia be milled?
Lava Esthetic zirconia discs are optimized for dry milling processes and can be milled with CAM strategies and parameters suitable for zirconia.
However, the surface quality of milled restorations and the yield rate greatly depend on set milling parameters, machine and tool types and the interaction of Lava Esthetic zirconia discs with your system. Thus, the following milling parameters are recommended:
Step down (mm)
Step over (mm)
Spindle speed (RPM)
Carbide tool diameter (mm)
Rest material roughing
Finishing inside 3D/occlusal
Finishing margin line 3D
Finishing outside cavity
Fine finishing inside 3D
Fine fissure machining
Please ask your CAM module and mill supplier for help to adapt the parameters in your system if necessary.
Is Lava Esthetic zirconia compatible with 3M™ Lava™ Frame or Lava Plus dyeing liquids?
No. Lava Esthetic zirconia must not be used in combination with any dyeing liquids. The use of dyeing liquids can reduce the strength of the material and compromise fluorescence and shade match.
What is the sintering cycle for Lava Esthetic zirconia?
20 °C/min to 800°C 10 °C/min to 1,500°C
120 min at 1,500°C
Max. 15 °C/min to 800°C Max. 20 °C/min to 250°C
In our lab we already use certain sintering cycles for zirconia. Is it ok to sinter Lava Esthetic zirconia with my current cycles?
No. Lava Esthetic zirconia must be sintered with the cycle displayed above. Using a different sintering cycle can have negative effects on strength, translucency and/or shade.
What is the drying time of Lava Esthetic zirconia after shading with liquids? Is there a special sinter program including a drying step?
There is no drying time because Lava Esthetic zirconia must not be used in combination with any dyeing liquids. The use of dyeing liquids can reduce the strength of the material and compromise fluorescence and shade match.
What is the recommended finishing for full-contour Lava Esthetic zirconia restorations?
It is recommended to glaze restorations to achieve the best match to the selected shade and a natural, esthetic appearance.
Alternatively, the restoration can be polished using rubber polishers and polishing brushes with diamond polishing paste. This may cause a change in the shading results. This can be avoided, in part, if a shade lighter than desired is selected.
Which stains and glazes can be used?
Low-temperature (< 900 °C) firing glazes and stains suitable for use with zirconia must be used. A vacuum during the glaze firing holding time is not recommended. When Lava Esthetic zirconia is used in combination with a glaze, the manufacturer´s instructions for use must be observed.
Examples of compatible glazes:
Examples of compatible stain systems:
• Creation ZI/ ZI-F Glaze
• IPS e.max® Ceram Shades
• IPS e.max® Ceram Glaze
• IPS Ivocolor™ Universal Stains
• VITA AKZENT® Plus LT Glaze
• VITA AKZENT® Plus
• Amann Girrbach Ceramill® Glaze
• Amann Girrbach Ceramill® Stains
• Noritake Cerabien ZR External Stain Kit
How can I cement a restoration made of Lava Esthetic zirconia?
For final cementation of crowns and bridges, 3M recommends using 3M™ RelyX™ Unicem 2 Self-Adhesive Resin Cement offering high bond strength and ease of use without compromising reliability and esthetics. Depending on the requirements, Lava Esthetic zirconia restorations may be cemented either conventionally (e. g. with glass ionomer cements such as 3M™ Ketac™ Cem Glass Ionomer Luting Cement or a resinmodified glass ionomer cement such as 3M™ RelyX™ Luting Plus Cement) or adhesively (e. g. with 3M™ RelyX™ Unicem 2 Self-Adhesive Resin Cement or 3M™ RelyX™ Ultimate Adhesive Resin Cement).
How do I pre-treat the bonding surface of Lava Esthetic zirconia?
Bonding surface must be sandblasted (30–50µm median particle size alumina, 2 bars/30 PSI). HF etching does not work.
If sandblasting is done in the lab, please make sure to clean the restoration surface with 5.4% NaOCl solution (Sodium Hypochlorite Bleach Solution), rinse and dry after the final try-in right before applying the cement. Do not clean with phosphoric acid.
Can sandblasting or diamond grinding reduce strength?
Yes. In general, strength is lowered by surface roughening of a ceramic material. This is true for mechanical treatment of all cubic zirconia materials as well as for HF etching of glass ceramics.
If adaptations were made to a restoration with diamond tools, make sure scratches or rough surfaces are smoothened with rubber polishers used for ceramics before cementation.
Fatigue studies conducted at the University of Alabama, Birmingham, have shown that sandblasting does not have a negative impact on the durability of Lava Esthetic zirconia restorations when cemented with RelyX Unicem 2 cement.
Do I need a primer for Lava Esthetic zirconia?
Follow the instructions of the cement you use – if it says use a certain primer for zirconia then you should do that. 3M recommends using RelyX™ Unicem 2 cement which does not require a separate primer for cementation of Lava Esthetic zirconia crowns and bridges.
How can restorations made of Lava Esthetic zirconia be adjusted and polished intra-orally?
Lava Esthetic zirconia is easier to adjust and remove in comparison to conventional zirconia. Adjust as needed with fine-grain diamond bur and water cooling. Make sure to maintain a minimum wall thickness of 0.8 mm. Polish adjusted areas with rubber polishers used for ceramics.
Attempting to place implants in patients with a pneumatized maxillary sinus can create a challenging situation for many dental implant practitioners. Evaluation and management of the deficient posterior maxillary region is handled via CBCT diagnostics and the use of the CAS-kit Approach Sinus Kit from Hiossen. Flap reflection, drilling sequence, hydraulic lifting of the Schneiderian Membrane, utilization of PRF and Allograft bone, and finally immediate implant placement is highlighted in a conservative crestal approach, without the need for opening the traditional lateral window. Attendees will understand how utilizing this technique can safely achieve anywhere from 6-8mm of vertical height in what is one of the most common, yet challenging regions to work in for implant dentistry.
