Guidelines for Clinical Management of Laser-Etched (Laser-Lok) Abutments in Two Different Clinical Scenarios: A Preclinical Laboratory Soft Tissue Assessment Study
Neiva, Rodrigo / Tovar, Nick / Jimbo, Ryo / Gil, Luiz F. / Goldberg, Paula / Barbosa, Joao P. M. / Lilin, Thomas / Coelho, Paulo G.
One-stage implants were placed in the mandibles of eight beagle dogs with laser-etched (LL) and machined abutments. After 4 weeks, half of the LL abutments were disconnected and reconnected after 10 minutes of saline storage, and the other half were replaced with a new LL abutment (impression simulation) with or without sulcus de-epithelialization. After abutment change, systems remained in vivo for 3 weeks. Results showed that LL abutments can be reconnected and that sulcus scoring prior to LL placement of onestage implants receiving machined abutments may be beneficial.
