Abstract
Ten patients requiring the extraction of a
severely-deteriorated molar or premolar before placement of a dental implant
for prosthodontic rehabilitation were selected (6
women; 4 men). The sockets were curetted and decontaminated with an 810 nm
wavelength diode laser using a 400 micron fiber at close distance (1 mm) from
the target area, power setting 2.5 W, pulsed mode (10 msec
t- on, 10 msec t-off for five seconds, three
repetitions for each bone wall, 30 seconds pause between each irradiation). The
socket filled with β-TCP plus Tissucol and
primary closure was attempted. In addition all patients were treated with a 810
nm GaAlAs laser, in continuous wave mode, defocused
hand-piece, 50 J\cm2 ( 1W for 50 seconds) after surgery and on days 3, 5, 7
postoperatively. At 18 months after prosthodontic
treatment and loading, the implant was stable. Laser therapy, combined with a
graft of biomaterial composed of β-TCP and tissucol,
prevented alveolar crest resorption follo wing tooth extraction. Formation of new bone of
acceptable quality and quantity permitted placement of osseointegrated
dental implants.
