Background: Short clinical crown is a common problem in patient with severe attrition teeth. Many attempts can be done but surgical crown lengthening is preferred for increasing clinical crown height. Nowadays, laser is a new technology with many advantages that can be used for surgical crown lengthening. Objective: The purpose of this case report is to present the surgical crown lengthening procedure by using Er:YAG laser and Nd: YAG laser to increase crown height on the short clinical crown teeth. Method: This reported a case on a 64-year-old Thai male patient with complaint of short clinical crown: Clinically, 2 millimeters of clinical crown height was presented on the lower anterior teeth that was insufficient to be abutment. There was no pocket more than 3 millimeters. Keratinized tissue was 5-8 millimeters. From the radiograph, no bone loss was detected. All of lower anterior teeth were classified as Coslet Type I-B. After local anesthesia injection, Er:YAG laser set energy at 150 millijoules (mJ) frequency 10 hertz (Hz) with water spray expressed, ginigivectomy was performed with laser to depth of the bone crest. Then ostectomy was done by using Er:YAG laser set energy at 300 millijoules, frequency 10 hertz with water spray expressed to reduce bone height 1-2 millimeters. After that, bleeding was stopped by Nd:YAG laser set energy at 1 watt. No dressing was applied after the surgery. Paracetamol and chlorhexidine 0.12% mouth rinse were prescribed postoperatively. Result: At 1 month post-op, the result showed the clinical crown height of all treated teeth increased by 1-2 millimeters. No complaint about pain or any discomfort was reported, wound healing was undergone eventually without any problem. Conclusion: Er:YAG in accompany with Nd:YAG lasers is a useful method that can be performed crown lengthening. They can be an alternative method to conventional technic with many advantages such as less pain, less bleeding and self-sterile.
