The ablated surface exhibits a microstructured appearance with minimal thermal alteration.8 The peri-implant soft tissue is of major importance in the upcoming prosthetic stages since the gingival tissue attachment around implants is one of the fac- tors of success of implant rehabilitation, especially in aesthetic areas.12 In this laser, the photon amplification occurs through a medium of heterogeneous crystal (YSGG). This laser emits photons at 2,780 nm wave- lengths and has a pulse duration of 140 to 600 µs in the repetition rate that can vary from 10 to 50 Hz. The major beneficial properties of lasers are their relatively easier ablation of soft tissues than that of mechanical instruments and their haemostatic and bactericidal effects. There are two surgical stages for conventional im- plant dentistry. The first stage consists of performing the implant fixture while the second stage consist in uncovering it. The second stage is less aggressive for the patient comparing to the actual surgery but pres- ents more pain.9 Dental implants can be exposed by using scalpel, punch, electro surgery, or laser uncovering that de- crease bleeding, swelling, and postoperative discom- fort. Electrosurgery has frequently been employed and is capable of easily incising soft tissues with good haemostasis but unwanted thermal damage can cause delayed wound healing.10, 11 Kurz & bündig Conclusion The advantages for laser treatment include tech- nical simplicity, the possibility of obviating local an- aesthesia, absence of postoperative pain and oedema as well as predictable results and complete tissue healing in several days, as it will facilitate rapid pros- thetic rehabilitation._ contact Dr Habib F.

Dabei ist der Erbiumlaser der meistgebrauchte Laser in der modernen Zahnheilkunde, da er sowohl für Hart- als auch Weichge- webe verwendet werden kann und damit eine Vielzahl an Anwendungsmöglichkeiten bietet. In der dentalen Chirurgie lässt sich der Erbiumlaser beispielsweise zur Entfernung krankhaften Gewebes, zur Tumorentfernung, Behandlung aphthöser Geschwüre oder zur Durchführung einer Frenektomie verwenden. Darüber hinaus eignet er sich auch für parodontologische Eingriffe, wie Weichgewebskürettage, Entfernung von krankem, infiziertem oder nekrotischem Weichgewebe in der Parodontaltasche und zur Entfernung von hochgradig entzündetem, ödematösem Gewebe. Im Fallbericht schildern die Autoren den Einsatz eines Er,Cr:YSGG-Laser in der zweistufigen Implantatchirurgie für eine verbesserte Rehabilitation und Ästhetik.
