What this Trial Is About
The goal of this clinical trial is to learn if using zirconia-based composite customized healing abutment can have a favorable effect on peri implant soft tissue that may be related to the superior biological properties of zirconium nano particles regarding increased biocompatibility and decreased inflammatory response Patients that are eligible for implant placement The main question it aims to answer is: Does zirconia-based composite customized healing abutment have a significantly different effect on peri-implant soft tissue compared to conventional composite customized healing abutment in terms of biological properties or biocompatibility or inflammatory response? Researchers will compare between direct zirconia-based composite customized healing abutments vs conventional composite customized healing abutments placed simultaneously with delayed dental implant placement. Participants will be undergo the following procedures : A) Presurgical procedures: 1. Detailed clinical examination, full history, and radiographic examination (CBCT) will be performed initially to aid in patients' selection. 2. After enrollment, all participants will sign the informed consent. 3. All participants will be subjected to periodontal phase I treatment including periodontal supra- and sub-gingival debridement and oral hygiene instructions. B) Surgical procedures: 1. After local anesthesia administration, flap is raised, osteotomy site preparation, and implant will be placed. 2. Check the ISQ to exceed or equal 70 unit. 3. A customized Light-cured Direct Zirconia-Based Composite or A customized Light-cured Direct Convential Composite Healing Abutment will be placed. Then all participants should follow up at the following times : Baseline, 1,2 and 3 months after implantation.
