UV Activator

EN KR

Beginning of all newness in the world Again. Everything. Newly.: DIO finally launched UV Activator2 officially,
the next generation surface processing system with integrated innovative technologies that have not been experienced in the past.
UV Activator2 is a surface processing system that turns the SLA-surface processed titanium surface into hydrophilic
in nature by removing a diverse range of organic impurities adsorbed onto the surface such as
hydrocarbon through photo-radiation processing.
It is recognized as the next generation surface finishing method with both advantages of the dental titanium surface processing method
researched for execution at processing unit until now and acquisition of hydrophilicity of the surface advantageous for osseointegration.

In addition, UV Activator2 drastically reduced ‘UV Irradiation Time’ from 20 minutes to 20 seconds by
perfectly supplementing the UV ray penetration, absorption and losses of the existing system.

Along with the assessment that innovation has been added to existing innovation,
many clinicians in Korea are already looking forward to it.

20 Miraculous Seconds!

Before UV Activation

Liquids form drops,
fail to penetrate threads

After UV irradiation

Liquids are drawn to surfaces
and don’t form drops!

20초의 기적!: 20초만에 티타늄 표면 개질 (소수성 → 친수성)

개질[改質, Reforming]: 촉매의 작용에 의하여 탄화수소의 구조를 변화시켜 표면을 개선시킴

Utilization of the UV Activator

Renders the titanium surface FREE of any organic material,
including all hydrocarbons!

Before UV activation

Titanium surfaces acquire organic debris,
like hydrocarbons, over time.

[Professor Takahiro Ogawa et al., UCLA Dental University]

After UV irradiation

The UV exposure renders the surface hydrophilic
by removing all organic compounds through
photocatalytic action

Renders the titanium surface FREE of any organic material, including all hydrocarbons!

An active increase is demonstrated in both cell growth rate and bone formation.: MC3T3-E1 Proliferation; Cell growth rate increased sharply after
day 3 for UV photofunctionalized implants

Renders the titanium surface FREE of any
organic material, including all hydrocarbons!

An active increase is demonstrated in both cell growth rate and bone formation.: MC3T3-E1 Mineralization; Bone formationality increased rapidly within 2~3 weeks
for UV irradiate implants.
Bone formationality increased rapidly within 3~4 weeks
for implants that were not UV irradiated.

Comparison of binding power between two different implants by placing UV implant in #17 and SA implant in #16.
There were not complications except for typical edema and pain. ISQ value towards buccolingual (BL) and mesiodistal (MD) of implant were checked on the day of surgery, 1week later, 4 weeks later and 8 weeks later.
It was observed that the ISQ value of SA treated implant in #16 did not change substantially, but ISQ value of #17 implant irradiated with UV light right before placement-for 15 minutes-increased continuously from 4 weeks to 8 weeks.
As a result, fast osseointegration in weak or insufficient bone can be aided.

Clinical Case Report: Maxillary Anterior Case

Maxillary Anterior Case: Yeosu More Dental Hospital Dr. Jeongrok Jang

Tooth mobility in #11 and 21 was displayed 4 years ago when patient first visited the hospital, but patient refused treatment.
Therefore, the area was fixed using G-fix, then due to repeated failure, patient finally decided to get implant surgery.

Final prosthesis was planned to be loaded two months after surgery using UV implants, but was instead loaded after 4 months due to personal reasons.
