An electronic search in MEDLINE (PubMed) and Embase was performed up to May 7, 2026. Eligible studies included RCTs comparing concave (test group) and convex (control group) transmucosal prosthetic designs and reporting midfacial mucosal level changes (mm). Data extraction and risk of bias assessment (RoB 2) were performed independently. A random\u2010effects meta\u2010analysis was conducted using weighted mean differences (MDs) and 95% confidence intervals (CIs).

Of these, 128 implants contributed to the quantitative synthesis, with 66 implants allocated to the concave\/modified emergence profile group and 62 implants allocated to the convex\/non\u2010concave emergence profile group. The pooled analysis demonstrated a mean difference of \u22120.31\u2009mm (95% CI \u22120.63 to 0.02;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.064), indicating a trend toward greater midfacial mucosal recession with convex emergence profiles compared with concave designs.
