summary The aim of the present study was to evaluate the influence of implant bed preparation using an Er:YAG laser on the osseointegration of titanium implants. A total of 24 implant channels were prepared in the lower jaws of four beagle dogs using (i) an Er:YAG laser device (ERL), or (ii) conventional drills (CD) according to a split‐mouth design ( n = 6 implant channels per animal). Three screw‐type titanium implants of different manufacturers were randomly inserted in both groups to evaluate submerged healing at 2 and 12 weeks. Width of the peri‐implant gap (WPG) and bone‐to‐implant contact (BIC) were assessed histomorphometrically. There were no identifiable signs of any thermal side effects in both groups. ERL osteotomy frequently resulted in wide peri‐implant gaps particularly in the apical area of the implant supporting bone. The following mean scores were assessed (± s.d.): WPG (2 weeks): ERL: 0·89 ± 0·48 mm; CD: 0·27 ± 0·09 mm ( P < 0·001 respectively); BIC (2 weeks): ERL: 34·5 ± 7·76%; CD: 48·5 ± 11·08% ( P < 0·001 respectively); BIC (12 weeks): ERL: 64·1 ± 8·97%; CD: 68·94 ± 11·23% ( P > 0·05 respectively). Within the limits of the present study, it was concluded that ERL may represent a promising tool for implant bed preparation.
