LASER AND TITANIUM INTERACTION

The aim of this study is to verify, by means of microscopic SEM analysis, the interactions of different laser wavelengths on the titanium grade 4 and grade 5 surfaces commonly used in dentistry for the creation of implant screws for the replacement of dental missed elements; focusing attention on a new Q-Switch Nd:YAG laser device. To date, dental prosthesis on implants is considered the best solution for the rehabilitation of edentulous areas; this is demonstrated by the fact that around 5,000,000 dental implants are placed every year around the world. Hand in hand with the spread of implantology, there has also been a significant increase in cases of peri-implant disease, a multifactorial disease mainly of bacterial origin which, in the long run, can lead to implant loss. [1]. However, nowadays, it has not yet been possible to identify a truly predictable therapy for the treatment of these pathologies. Among the innovative technologies most used in the treatment of peri-implant mucositis and peri-implant disease, one of the most promising is certainly laser light. [2]. In fact, as already shown by publications in the literature, the use of laser devices is able not only to decontaminate the implant surface and the surrounding areas, but also to stimulate tissue repair, thus speeding up healing times.
