Nowadays the use of implants as an increasing therapy in dentistry and it has become a usual treatment in dental offices. More and more dentists have dental implants included in treatment plans for patients with missing teeth. Therefore is necessary that all dentists know all the possibilities of these treatments. Together with the emergence of dental implants, it is also beginning to see an increase in the onset of lasers in dentistry.These two new techniques in dentistry can be supplemented because as we will see the use of lasers in different cases can improve implant treatment.The laser implantology applications can be classified by the time that we are going to use it. We can use it in the first surgical phase, during the second surgical phase or on posterior phases that present some soft tissues or perimplantitis alterations.First surgical stage: In this phase we can use surgical lasers as Er: YAG and Er, Cr: YSGG to prepare the bone so the implant can be placed. Different studies have demonstrated that it can improve and accelerate the osseointegration, when they are compared with other conventional methods. Lee & cols compared the values of stability implants (ISQ) between the samples one made with laser and the other one with conventional bur technique. They observe that there are no differences.To sum up we can say that on one side we have that the sample of the bone made with Er: YAG or Er, CR: YSGG laser is a reliable one, and does not influence negatively in contact with the bone implant, but there is an increase of the needed time and a risk of nobles injuries (vessels and nerves).On the other side during the first surgical phase it also can be use the low level laser. In different experimental in vitro studies it has been compared how the irradiation with low level laser LLLT during the first surgical implant phase can speed up the wound process producing a biostimulation effect on the osteoblasts.Second surgical stage: Before this treatment can be enforce, the possible effects of the laser on the implant surface have to be established. That is why there is a need to know what are the laser effect on the surface of the implant and also if the temperature of tissues surrounding the implant is increased by the laser irradiation.In reference to the increment of the temperature in numerous studies, there evaluated this increment in function of the used wavelength.lasers such as Nd: YAG have shown they can produce a thermic damage in the adjacent bone to implants due to a temperature increment, so its use is discouraged in implantology. However Er, Cr: YSGG and Er: YAG laser on the implant surface do not generate a thermic increase as long as is used with refrigeration. Diode laser can increase the temperature above 10oC when is irradiated for more than 10 seconds.In the second-stage surgery of submerged healed implants Er: YAG or Er, Cr: YSGG laser has a successful result, but implants located in aesthetic zone or in areas with insufficient surrounded by keratinizedmucosa it will be a problem. In order to improve these results, we purpose a new technic to improve this procedure so instead to eliminate all the keratinized mucosa, we recommend a rolling-flap, so that the keratinized mucosa in palatine zone can be move to the buccal zone so the keratinized mucosa is preserved to the maximum.
