Can Combination of Low-Level Laser and Light-Emitting Diodes Enhance Stability of Dental Implants?

Not Applicable

Completed

• Conditions: Dental Implant Healing

• Registration Number: NCT03362307
• Lead Sponsor: Shiraz University of Medical Sciences

Brief Summary

Subjects were assigned in two groups: In group 1, subjects received LLL and LED 20 min/day for 10 days after implant insertion, subjects in group 2did not undergo LLL and LED. implant stability quotients(ISQs) were measured in 0,10,21,42 and 63 days after implant placement.

Detailed Description

Subjects eligible for study inclusion had an edentulous area at the first molar of the mandible and needed a dental implant. Subjects were excluded from study enrollment if they had any diseases that affect bone, smoking, insufficient bone in the edentulous area which needs bone augmentation, failed to return for follow-up, or refused study enrollment.

All implants were placed at least 3 months after tooth removal. The size of implants was 4.8X 10 mm (Zimmer, USA) Subjects were aligned based on computer randomization in two groups: In group 1(intervention), subjects received LLL and LED after implant placement and in group 2 (control) the same device was used while device was off.

A portable device was applied for irradiation of the intervention group with combination of 810nm laser and 632nm LED.

Subjects in group 1 underwent LLL 15 mw/cm2 and LED 10 mw/cm2 20 min every day for 10 days.

The mesiodistal and buccolingual directions were measured and the mean implant stability quotients (ISQs) were determined. The RFA measurements were performed in immediate after insertion (time0) 10 days (time1), 3 weeks (time2), 6 weeks(time3) and 9(time 4) weeks after implant placement.
