Comparison of Immediate Implant Placement With Titanium Mesh Versus Collagen Membrane in Type II Socket:

Statement of the problem: Immediate implant placement is faced with several problems. One of the most important issues is dealing with defects in the buccal plate of bone in the esthetic zone.

Aim: The aim of this study is to assess the buccal bone thickness after augmentation with titanium mesh and xenograft upon flapless immediate implant placement.

Materials and Methods: This parallel arm, randomized controlled clinical trial will involve systemically free patients with remaining roots or badly decayed teeth in the anterior region and buccal bone deficiency requiring implant placement. They will be randomly allocated to two equal groups. Group A (test group, n=10) will receive immediate implants (grafting with xenograft covered by titanium mesh covered by collagen membrane), while group B (test group, n=10) will receive immediate implants (grafting with xenograft covered by collagen membrane). The parameters ( buccal bone thickness & soft tissue thickness will be assessed at 6 & 12 months. Postoperative pain and swelling will be recorded daily by the patient for the 1st two weeks post surgically. Postoperative medication will be prescribed to the patient and postoperative instructions will be explained in detail. Follow-up will be performed to assess the parameters and to ensure performing proper oral hygiene. Data collected will be tabulated and statistically analyzed.
