Abstract

|
|
Purpose: The objective of this systematic review was to obtain the comprehensive survival rates of short implants. Then it was examined that whether treatment using short implants has favorable results.
Methods: A MEDLINE search was performed, the data obtained from many articles about length, diameter, site of placement, surface treatment and prosthetic design were analyzed.
Results and Discussion: The data obtained from many articles were analyzed, and it was found that the survival rate of short implants was 95.87%, short implants has similar outcomes to those reported for standard implants. On the other hand, in the comparison the survival rate of 3 groups divided by the diameter of implants under 4 mm, 4 - 5 mm, and above 5 mm, a statistically significant difference was detected in under 4mm group. In implant group with 6 - 7 mm length, a group with 5 - 6 mm diameter has survival rate of 97.01%, groups with 3.1 - 4.8 mm diameter has survival rate of 92.96%, which was statistically significantly different. In the result of surface feature, the roughed surface groups of short implant showed a higher survival rate by approximately 6.3% than machined surface group. In the result of prosthetic design, survival rate of short implant was considerably lower for the single implant crown group (94.3%) than splinting group (99.4%).
