Summary

The purpose of this randomized clinical trial is to assess the pink esthetic score with three different techniques in second-stage implant surgery.

Conditions

  • Papilla Reconstruction

Interventions

PROCEDURE

Mid-Crestal Sulcular Incision

A long incision over the crest and midway between buccolingual aspect through the gingiva from the site of the distal implant in mesial direction with intra-sulcular incisions in the teeth adjected to the implant site · Following a full or partial thickness flap is raised to establish access to cover screw.

PROCEDURE

Split-Finger Procedure

The surgical technique first designs 3 interlacing "fingers" over and adjacent to each implant site and will be extended around each adjacent tooth. · A sulcular incision will be made 2 to 3 mm to the palatal side from each tooth with a loop design (at least 2.0-2.5 mm) adjacent to the implant location. · The incisions will then be joined facially with a semicircular incision at the preplanned free tissue margin of the implant crown. · The facial "fingers" will be elevated to the desired interimplant height for the papillae. The middle "palatal finger" will then be split and reflected to the respective mesial and distal sides (each is at least 2.0-2.5 mm wide). · The soft tissue maintains its elevated position with a permucosal extension or a final prosthetic abutment that is extended through the soft tissue. · A modified vertical mattress suture will then be used to suture each papilla using 4-0 or 5-0 Gut or Vicryl sutures.

PROCEDURE

"I" shaped incision

A Labial horizontal incision with a #15c blade will be performed mesiodistally 0.5-1.0 mm inside from the labial border of the implant. A horizontal incision will also be performed, parallel to the buccal side, on the palatal side, which is in contact with the palatal border line of the implant different from the labial side. Another incision will be done bucco-lingually over the implant midline perpendicular to the horizontal incision lines performed on the labial and palatal sides. The flap will be reflected with care and the implant will be exposed to remove the cover screw. The healing abutment will be connected and both flaps will be folded up alongside the healing abutment intending them to heal without suture.
