No results posted yet for this study

Summary

The aim of the current study is to evaluate the use of a PEEK shell placed in the anterior maxilla placed by tunnel technique in decreasing the gingival display

Conditions

  • Excessive Gingival Display

Interventions

OTHER

tunnel technique with a 3D printed PEEK shell to fill the skeletal subnasal depression

The area will be anesthetized using infiltration technique with 1.5ml of anesthetic solution containing Articaine Hydrochloride 68 mg/1.7 ml with Adrenaline 0.017 mg/1.7 ml Two bilateral full thickness vertical incisions will be created using a #15 blade. One on each side of the frenum A subperiosteal tunnel connecting the two vertical incisions will be created using a periosteal elevator/tunneling knife until the complete communication between the two ends is established The custom made PEEK framework will be inserted from the incision on one side and eased through until it sits in the subnasal concavity. Once fitted in place the shell will be fixed in place using two mini screws bilaterally, one on each side. The two vertical incisions will be closed by interrupted sutures 6-0 Polyglycolic acid suture material
