However, its effect on the mechanical strength of the implant is still uncertain.

Half of the implants underwent implantoplasty with tungsten carbide finishing burs. Weight, volume, and surface roughness of the implants were recorded prior to and after instrumentation. All implants were subjected to static loading to failure or fracture and the implant surfaces were then analyzed using optical microscopy. Finite element analysis was carried out to assess the stress pattern on dental implants after implantoplasty.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Implantoplasty significantly reduced the fracture resistance of implants with all defect morphologies, aside from those with 3\u2009mm of circumferential bone loss. Implants with 5\u2009mm of peri\u2010implant bone loss also experienced significantly reduced fracture resistance compared to the 3\u2009mm group. Significant decrease in fracture resistance was only observed between the circumferential and semi\u2010circumferential groups with 5\u2009mm of bone loss. Surface roughness was also significantly reduced following implantoplasty. The results from finite element analysis revealed a change in pattern of stress concentration in the implant after implantoplasty.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Implantoplasty negatively impacted the fracture resistance of standard diameter dental implants in most scenarios. The increase in exposed implant length resulted in a decrease in fracture resistance.
