Evaluation of Loading Stresses on Multiunit Abutments in Short Implants – An In vitro Study
Aim: This study aims to measure the displacement of straight abutment and multiunit abutment with straight abutment after static loading of 200 N at 30-, 40-, and 45-degree angulations. Materials and Methods: 30 implants were divided into two groups according to the abutment used: Group I – Implant...

| Summary: | Aim:
This study aims to measure the displacement of straight abutment and multiunit abutment with straight abutment after static loading of 200 N at 30-, 40-, and 45-degree angulations.
Materials and Methods:
30 implants were divided into two groups according to the abutment used: Group I – Implant with straight abutments; Group II – Implant with multiunit with straight abutments. Fracture load was determined using a compression load on the abutments with a universal testing machine.
Results:
The data were analyzed with one-way analysis of variance (ANOVA) and Tukey’s Post Hoc test. A significant difference was noted between the groups (P ≤ 0.05). Short implants adequately took up static loading and may be advocated. Minimum displacement occurred in Groups I and II at static loading of 200 N in 30- and 40-degree angulation, which was statistically significant. Maximum displacement occurred in Groups I and II at static loading of 200 N in 45-degree angulation.
Conclusion:
Multiunits may improve the crown height space and reduce stress concentration at implant abutment junction. Within the limits of the study, it may be concluded that short implants may be advocated with straight abutment and/or multiunit with straight abutment. |
