Official title

Impact of Modified Periosteal Inhibition Technique on Alveolar Bone Stability in Immediate Implant Placement Procedures (Randomized Controlled Clinical Trial)

Overview

To clinically and radiographically assess the impact of the modified periosteal inhibition (MPI) technique, applied during immediate post-extraction implant placement, on alveolar bone dimensional changes, in comparison to the conventional flapless immediate implant approach.

Detailed description

To assess the impact of the modified periosteal inhibition (MPI) technique, applied during immediate post-extraction implant placement in comparison to the conventional flapless immediate implant approach on radiographically by assessing marginal bone level measurements and bucco-lingual alveolar width. Clinically, pain levels, wound healing index, primary, secondary implant stability measured by resonance frequency analysis (RFA), peri-implant probing depth, and pink esthetic score (PES) will be assessed.

Interventions

  • Procedure Immediate implant placement via flapless approach
    Implant site preparation will be performed flapless using 3D computer assisted planned surgical stent. Implant site preparation will be performed using commercially available standard surgical kit. A single customized screw-type healing abutment will be screwed to the implant. Cortico-cancellous bone allograft will be inserted inside the extraction socket in the gap distance between the implant and surrounding alveolar bone of the fresh extraction socket.
  • Procedure Immediate implant placement in conjunction with modified periosteal inhibition technique using collagen sponge in the gap distance
    After papillae incisions, an intra-sulcular incision will be made on the vestibular side of the extraction socket, extending to the mesial and distal mid-tooth with a #15c surgical scalpel. Implant site preparation will be performed using 3D computer assisted planned surgical stent. Implant site preparation will be performed using a standard surgical kit. A single customized screw-type healing abutment will be screwed to the implant. A full-thickness flap will be elevated creating a room that wo

Primary outcome measures

  • Radiographic evaluation of horizontal and vertical dimensional changes of the alveolar bone placement by using cone beam computed tomography (CBCT). [Time frame: Baseline, 6 months, 12 months after the implant placement]
Secondary outcome measures (5)
  • Pain Index [Time frame: first post-operative day, third day and after one week.]
  • Wound Healing Index (WHI) [Time frame: 1 and 2 weeks after surgery]
  • Implant Stability Measurements [Time frame: The RFA measurements will be made immediately after implant installation, and 3 months after implant placement before the prosthetic phase.]
  • Peri-implant Probing Depth (PPD) [Time frame: Baseline, 6 months and 12 months post-operatively.]
  • Esthetic Evaluation [Time frame: At the time of prosthetic phase (3 months after implant placement), 6 months, and 12 months postoperatively]
