Summary

Crown lengthening is a clinical procedure that involves reshaping the gingiva, and sometimes bone, in order to expose more of tooth's structure. The procedures is performed for both functional and aesthetic reasons. In certain instances, this procedure is performed to This procedure is commonly performed for both functional and aesthetic reasons, such as to prepare a tooth for a crown or to enhance the appearance of a smile. Traditional crown lengthening techniques typically involve surgical methods that can be invasive, leading to extended recovery times and postoperative discomfort in this study we compare traditional versus the laser aided crown lengthening to compare the periodontal parameters in both cases.

  • Crown Lengthening
  • Crown Lengthening Procedure With Ostectomy
  • Laser
  • Piezoelectric Technique

Interventions

PROCEDURE

conventional surgical crown lengthening by opening envelop flap

Bevel incision with number 15 blades is place on the margin following with sulcular incision and excess gingival tissues are removed using Gracey currets .in case if any granulation tissues are seen it should be removed and washed with saline. Following with bone recontouring and reshaping after periosteal elevator is used to expose the underlying bone. fissure burs or coarse diamond stones are used until thing bone tissues are left over the root and rest can be removed with scaler to prevent damage to the tooth. Resorbable sutures are place after the surgery and the case is followed up for 3 months period. In the case of conventional surgical crown lengthening, after delivering the local anesthetic solution to the surgical area, soft tissue recontouring starts. This procedure, which involves excising the soft tissue with a gingivectomy, is typically done to improve aesthetics or create more space for better restoration seating. The gingival border is typically 1 mm coronal to the CEJ.

PROCEDURE

crown lengthening using Er:YAG Laser

Er:YAG laser is used for both soft and hard tissue recontouring according to the manufacturer's guidelines. In the case of gingivectomy and soft tissue recontouring, 4x17mm, 0.6x17mm, and 1.3x17mm tips are used, and the soft tissue mode is selected on the device screen, which sets the device parameters to 100mJ x 20Hz. The tip is in direct contact with the soft tissue until the desired soft tissue level is achieved. For bone contouring, the hard tissue option is selected on the device's screen, setting the parameters to 150mJ x 20Hz. A non-contact approach is used to reshape the underlying bone.
