Comparison of Er,Cr:YSGG and Diode Lasers In Second Stage Implant Surgery

Study Overview
=================
Brief Summary
-----------------
The study evaluates postoperative pain, intraoperative bleeding and wound healing after second stage implant surgery. Submerged implants were exposed with diode laser in Group 1 (n=20) and by using Er,Cr:YSGG laser in Group 2 (n=20).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Diode laser<br>Soft tissue incision with 940 nm Gallium Aluminum Arsenide diode laser, at implant recovery settings (2.5 W output power, average power: 1.25 W, pulse length : 1.00 ms, pulse interval: 1.00 ms) in second-stage implant surgery. | Device: 940 nm Gallium Aluminum Arsenide Diode Laser<br>* Exposure of the cover screw of osseointegrated dental implants embedded under oral mucosa by performing the soft tissue incision with diode laser for placing the healing abutment.<br>|
| Experimental: Erbium laser<br>Soft tissue incision with 2780 nm Er,Cr:YSGG laser, at implant recovery settings (2.00 W power, 100 Hz, H mode, 10% water and 10% air) in second-stage implant surgery. | Device: 2780 nm Er,Cr:YSGG Laser<br>* Exposure of the cover screw of osseointegrated dental implants embedded under oral mucosa by performing the soft tissue incision with erbium laser for placing the healing abutment.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postoperative pain on 1st day | Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 1st day. Pain scores on the postoperative 1st day in each group are compared. | 1st Day | 
| Postoperative pain on 2nd day | Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 2nd day. Pain scores on the postoperative 2nd day in each group are compared. | 2nd Day | 
| Postoperative pain on 3rd day | Patients score pain intensity with numeric scale ranging between 0(no pain) to 10(most severe pain) on the postoperative 3rd day. Pain scores on the postoperative 3rd day in each group are compared. | 3rd Day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of analgesics used daily | Analgesic consumption per day on postoperative 1st, 2nd and 3rd days. | 3 days | 
| Intraoperative bleeding | Bleeding during surgical procedure was scored by the physician as 1=minimal, 2=normal and 3=excessive bleeding | During operation |
