The aim : Of this study is to show which technique can be enhance the amount of keratinized tissue width (KTW) to improve the soft tissue profile after flapless implant placement..
Materials: A 14 patients (6 women and 8 men) aged between 25-70 years with mean value (47.5 years) were enrolled in this study. First group consisted of seven patients in which implants were inserted through trans-mucosal flapless technique, while the second group consisted of seven patients in which implants were inserted via punch flapless technique then the normal flapless surgical protocol for implant insertion was used and implant was covered by healing cap screw. KTW measured immediately before and after the surgery and at the time of the prosthetic finalization (3-4 months) for maxillary anterior and premolar regions..
Results: KTW at 1-2 mm (before) can be effectively increased, while no significant effect at
5 mm can expected. For the punch technique the mean value of KTW of 1-2 mm showed significant increase at 3-4 months postoperative ..
