Abstract
Objectives: to evaluate clinically and radiographically stability and tissue integration of laser
sintered implant and acid etched-sandblasted implant.
Subjects and methods: Ten implants were inserted in patients with unrestorable premolar or
molar teeth indicated for extraction. They were divided into two groups as the following: group < br /> A included patients who received dental implants with Laser- treated surface, group B included
patients who received implants with (SLA) sandblasted-acid etched surface. The patients were
clinically and radiographically evaluated preoperatively and postoperatively at the intervals of 4
month, 6 and 9 months. Clinical evaluation included pocket depth, gingival health, implant
stability using osstell, bleeding index, plaque index, pain and satisfaction. Radiographic
evaluation was done by using periapical radiographs to measure the marginal bone defect.
Results: Both Laser- treated surface implants and sandblasted-acid etched surface implants have
significant success rates with superior clinical and radiographic results of laser treated implants
over acid etched implants after a follow up period up to 9 months.
Conclusion: Laser and acid etched treatment are promising methods for roughening the implant
surface and both have significant success rates.
Key words: Laser treated, Acid etched, Dental implants.
