In a split\u2010mouth design, each animal received both narrow (NE) (emergence angle\u2009=\u200930\u00b0) and wide (WE) (emergence angle\u2009=\u200960\u00b0) abutments on each side of the mandible. The implants were subsequently splinted. Radiographic images were captured at 0, 4, 12, and 24\u2009weeks post\u2010restoration. Biopsy samples were then collected for histomorphometric analysis and circularly polarized light examination. All analyses were performed based on the splinted positions: either the mesial or distal end of the terminal implant, the splinted zone of the terminal implant, or the splinted zone of the middle implant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Radiographic evaluation showed more pronounced bone remodeling in the WE group. In histomorphometric analysis, both the vertical distance from the implant shoulder to the alveolar bone crest and the infiltrated connective tissue areas were significantly larger in the WE group. Conversely, the NE group exhibited a longer connective tissue attachment. Analysis using circularly polarized light indicated a significantly reduced area fraction of collagen fibers in the peri\u2010implant epithelium of the WE group, as well as in the oral epithelium of the splinted zone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A wide emergence angle
