Abstract Objective To compare the effect of placing definitive abutment at time implant placement versus a later stage, on soft and hard tissue changes around dental implants. Material methods Platform‐switched implants were placed in posterior maxilla or mandible partial edentulous patients they randomized to receive moment placement, 6–12 weeks later. Final prostheses delivered 2–4 Radiographic assessment vertical bone level (primary outcome), clinical status peri‐implant tissues, tissues margin, papilla filling, patient‐related outcomes adverse events assessed 6 12 months after loading. Results 60 40 patients, replacing single multiple absent teeth. One was lost 1 week insertion (overall survival rate: 98.3%). A statistically significant greater resorption from surgery post‐loading observed for those subjected change (control group: −1.24 ± 0.79 mm; test −0.61 0.40 P = 0.028). Periodontal parameters outcomes, however, did not demonstrate differences between groups any point. increase height loading all 1.17 1.47 0.98 0.89 mm) slight but coronal migration gingival margin. Conclusions The connection disconnection healing abutments is associated with significantly increased loss during period post‐loading, when compared one‐time placement.
