Within this framework, Group 1 aimed to formulate clinical recommendations on the number of implants required, timing of implant placement, and timing of loading.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>Group 1 followed the S2k-level guideline framework of the Association of the Scientific Medical Societies in Germany (AWMF), using a structured nominal group technique. The evidence base included three systematic reviews evaluating clinician-reported outcomes (ClinROs) and patient-reported outcomes (PROs), supplemented by structured single-round international surveys involving expert clinicians, patients, and cross-disciplinary experts. Survey content covered diagnostics, treatment planning, clinical procedures, and maintenance care. Draft recommendations were discussed during the in-person consensus meeting in Boston (June 16–18, 2025) and finalized through anonymous plenary voting. Consensus was defined as ≥ 75% and ≤ 95% agreement and strong consensus as > 95% agreement.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Group 1 formulated 12 clinical recommendations across the workflow domains of diagnostic tools, treatment planning, and treatment procedure.
