Abstract
AbstractAimTo evaluate the effectiveness and complications of the cushioned grind‐out technique. The primary outcome was endo‐sinus bone gain (ESBG), while secondary outcomes included the Schneiderian membrane perforation rate and mid‐ to long‐term implant survival.Materials and MethodsIn this retrospective study, we compared the cushioned grind‐out technique with the classic osteotome technique, establishing statistical models to assess ESBG, membrane perforation rate and implant survival rate.ResultsA total of 259 patients and 340 implants were included. The mean ESBG was 5.31 mm for the cushioned grind‐out group and 4.64 mm for the osteotome group. Multivariable regression analysis revealed that the cushioned grind‐out technique significantly facilitated ESBG (p = .028). Nineteen preparation sites experienced membrane perforation, with rates of 5.5% and 6.4% for the cushioned grind‐out and osteotome groups, respectively. However, the difference was not statistically significant (p = .920). Additionally, the cumulative survival rate of the implants for 7 years was 95.2% and 91.4%, respectively, with the surgical technique not significantly influencing the results.ConclusionsWith 6 months to 7 years of post‐prosthetic restoration review data, our findings show that the cushioned grind‐out technique facilitates a higher ESBG, with no significant difference in membrane perforation or implant failure rate.
