Abstract

Objective

To evaluate the therapeutic effects of erbium-doped: yttrium aluminium garnet laser (Er: YAG laser) combined with guided bone regeneration (GBR) in the treatment of peri-implantitis bone defect.

Methods

A total of 26 implants in 15 patients with peri-implantitis were selected and divided into experimental group (14 implants) and control group (12 implants) randomly. The experimental group was treated with Er: YAG laser combined with GBR, and the control group was treated with mechanical curettage with GBR. Clinical periodontal index test including plaque index (PI), sulcus bleeding index (SBI), probing depth (PD) and clinical attachment level (CAL) were checked at baseline, 3 months and 6 months. All the above data were statistically analyzed.

Results

All of the clinical periodontal index were improved after surgery. SBI, PD and CAL of the experimental group was 0.8 ± 0.2 mm, 5.8 ± 0.8 mm, and 2.3 ± 0.7 mm, while they were 1.1 ± 0.2 mm, 6.2 ± 0.6 mm, and 3.6 ± 0.6 mm in the control group. The experimental group showed better results than the control group (P < 0.05), while PI showed no difference between the 2 groups (P > 0.05).

Conclusion

The combined application of Er: YAG laser and GBR in the treatment of bone defect in peri-implantitis has good clinical effects.
