Researchers are evaluating the use of a magnesium membrane compared to a dual zone grafting technique for managing immediate dental implant sites. This study focuses on patients with hopeless maxillary teeth and thin buccal bone plates, aiming to see which method better preserves bone volume, improves aesthetic outcomes, and reduces pain after implant placement. The trial assesses these approaches in terms of bone density, soft tissue contour, and patient comfort. The study compares two treatments one uses a novel magnesium membrane placed between the soft tissue and buccal bone wall combined with inorganic bovine bone, and the other uses the dual zone concept where bone graft material fills both the bone and tissue zones around the implant. Both procedures involve atraumatic, flapless tooth extraction and immediate implant placement, followed by provisional restorations to support healing and maintain socket shape. Participants will undergo assessments before and after treatment at several time points up to 9 months, including measurements of ridge dimensions, pink esthetic scores, volumetric changes using digital scanning, mucosal recession, bone and soft tissue thickness, pain levels, and oral health indices. The trial includes safety monitoring and evaluates healing progress and implant site aesthetics over time. Total follow-up lasts 9 months after implant placement.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Day 1
Participants undergo atraumatic flapless tooth extraction followed by immediate implant placement using either the magnesium shield device or the Dual Zone grafting technique. A provisional restoration is placed to seal the socket and maintain the architecture.
1 visit (in-person)
Duration - 9 months
Participants are monitored for healing, pain, and implant site changes through clinical and imaging assessments.
Multiple visits at Day 3, 7, 14, 1 month, 3 months, 6 months, and 9 months (in-person)
