Abstract

This study's goal is to determine how well UV therapy works for placing dental implants. Panoramic X-ray, clinical image, CBCT were used to assess the effects of UV irradiation on reversing the biological aging process of implants. BIC is predominantly influenced by implant surface characteristics. Among the most popular methods of modifying an implant surface is the roughening of the surface using the sandblasted, large-grit, acid-etched (SLA) technique

Introduction

The most important factor for osseointegration of implants is the correct interface between macro- and micro-design, which varies depending on the classification of implants into three types based on external bone level, internal tissue level, and internal bone level. The implant surface has an approximately 50-nm-thick TiO2 oxide film. With time, hydrocarbons in the air are adsorbed on to the oxide film, leading to a biologic aging process that prevents osseointegration. [1-4]. The surface of implant begins to change from hydrophilic to hydrophobic after the manufacturing process. Efforts have been made to reverse this biological aging process and to induce the original hydrophilic state through UV irradiation. In line with this trend, in the present report, I will share my experience with UV machine (AB DENTAL) [5-10].

Materials and Methods

UV photo functionalization was performed by illuminating implants with UV light for 15 seconds using a specialized instrument (AB DENTAL UV ACTIVATOR ISRAEL). Specifications of the device were as follows: input voltage of AC 100 to 240 V ± 10%, input current of 2.2 A in maximum. Multiple UV lamps were utilized to create the UV light as a mixed spectrum at wavelengths of 172 nm. Inside the device, the lamps were arranged to illuminate an implant in all directions homogeneously. We have used Ab dental implants that have had their surfaces roughened with calcium phosphate particles before undergoing multiple thermal acid etching procedures to determine the microstructure and surface roughness of the implants. Then, gamma irradiation is used to sterilize all implants.

Discussion

Photo functionalization are due to improving hydrophilicity and eliminating hydrocarbon contamination on the implant surface in addition to antibacterial effects, UV activation would increase the adsorption of plasma proteins of human body and improve osteogenic cell attachment, spreading, and proliferation. There is an important bacterial colonization on implants only 30 min after implant insertion which may be prevented by UV-photofunctionalization restricting the growth of oral bacteria and biofilm. Peri-implant-diseases-associated biofilms would affect the long-term outcome of dental implants. The microbial composition between periodontitis and peri-implantitis are similar; however, dental implants are more susceptible to oral infections than natural teeth [11-14].

Conclusion

Many methods have been used to promote osseointegration for successful implant therapy, including photofunctionalization. UV photofunctionalization can change the surface wettability and eliminate the hydrocarbons that are generated by aging on the implant surface [15-17]. According our clinical experience using this machine we have a significative reduction in terms of osseointegration time also in case of immediate restoration and post extractive procedures. However, further studies must be conducted in the future.
