Immediate Implant Placement in Back Teeth Using a Sealing Socket Abutment and Socket Filling Compared to Standard Healing Abutment A Randomized Clinical Study

What this Trial Is About

Researchers are comparing two approaches for immediate dental implant placement in patients needing molar replacement in the upper or lower jaw. The study evaluates whether using a sealing socket abutment SSA with peri-implant socket filling better preserves the soft tissue contour around the implant compared to a standard healing abutment. Secondary goals include assessing changes in bone structure, soft tissue health, aesthetics, and patient-reported outcomes over time. Participants undergo minimally invasive tooth extraction followed by immediate implant placement using Straumann implants. The socket is filled with a bone graft material, and patients are randomly assigned to receive either a conventional healing abutment with collagen matrix closure or a customized SSA made chair-side using composite shaping and polishing. Antibiotics, anti-inflammatories, and oral hygiene instructions are provided. After three months, the abutments are removed, implant integration checked, and final zirconia crowns placed, replicating the abutment design. Participants will be monitored with follow-up visits at 7-10 days, 3 months, 6 months, and 12 months after surgery. Evaluations include standardized radiographs, 3D imaging to assess bone changes, soft tissue measurements such as probing depth and bleeding, aesthetic assessments, and patient questionnaires. The primary outcome is the change in soft tissue contour over one year, with ongoing monitoring of bone remodeling and soft tissue health to understand the implants effects and patient satisfaction.
