Compared to conventional scalpel technique, this method provides less  bleeding and pain and shorter healing period, leading to a better patient compliance. The objective  of this study is to contribute a comprehensive review on laser assisted second-stage of implant  surgery.  Materials and Methods: We searched Pubmed and Google Scholar databases using combined  keyword search or medical subject headings. Eight articles from 2009 to 2019 were identified  and assessed.  Results: Selected studies were categorized according to variables including amount of pain,  need for anesthesia, soft tissue healing, temperature rise and quality of impressions. All the reviewed  articles, measuring the amount of required anesthesia, agreed that laser-aided uncovering  of implants needs significantly less anesthesia compared to conventional scalpel technique.  Laser-assisted uncovering of their implants led to less pain. Ex-vivo studies measuring temperature  rise, suggested that application of a non-contact 445nm diode laser reduces the temperature  rise significantly. However, Er:YAG lasers proved to generate lower temperature rise. Diode lasers  showed no significant amelioration of soft tissue healing whilst Er:YAG and Er,Cr:YSGG lasers  revealed superior esthetic results and shorter healing period. Impressions can be taken 4-7 days  after the laser-assisted surgery with a satisfactory quality.  Conclusion: Laser-assisted uncovering of implants can be selected as an alternative over the  conventional scalpel technique. But, further studies are advisable.  Keywords: Laser assisted surgery; Dental implants; Uncovering; second-stage surgery. https://jcr.tums.ac.ir/index.php/jcr/article/view/311 https://jcr.tums.ac.ir/index.php/jcr/article/download/311/277
