Different dental lasers vs conventional technique for second stage surgery

Aim: was to compare diode, Er, Cr:YSGG and Er:YAG lasers and conventional scalpel surgery for dental implants exposure with regard to oedema, haematoma, postoperative pain and patients’ satisfaction. Material and Methods: Study consisted of 49 implants inserted in the lateral mandible, 36 in the study groups (12 per each laser group) and 13 in the control group. Three different dental lasers were used (high power diode laser, Er, Cr:YSGG and Er:YAG lasers) for implant recovery following manufacturer’s instructions. Control group was treated using scalpel for crestal incision technique with silk sutures. Three days after surgery oedema, haematoma, postoperative pain and patient’s satisfaction rate were assessed by a single examiner using VAS for patient’s evaluation. After 3 weeks delayed postoperative complications were evaluated. Statistical analysis was performed with v2 testand Mann-Whitney test. p-values lower than 0.05 were considered as significant. Results: No significant differences regarding age and gender were observed between the groups. Patients in laser groups had significantly lower oedema and haematoma scores compared to the patients in the control group (p < 0.05). Also reported (VAS) significantly lower pain and higher satisfaction rate compared to the patients in control group (p < 0.05), with slightly better results for Er, Cr:YSGG and Er. YAG lasers. There was no statistically significant difference between three examined lasers. After three weeks follow-up no postoperative complications or healing complications were found in both study or control groups. Conclusion: Dental lasers minimize postoperative complications for second stage surgery and can be used as an effective modality for implants exposure, due to precise incision, reduced bleeding and postoperative discomfort.
