The Effect of Insertion Angles and Depths of Dental Implant on the Initial Stability
Source abstract
Abstract
The objective of this study was to evaluate the effect of the measurement directions of the Periotest value (PTV) and implant stability quotient (ISQ) of dental implant fixtures inserted at various angles and depths. Five groups were organized: vertically inserted implants in an evencrestal position; implants inserted at a 17° tilt in a distal subcrestal position; implants inserted at a 17° tilt in a mesial supracrestal position; implants inserted at a 30° tilt in a distal subcrestal position; and implants inserted at a 30° tilt in a mesial supracrestal position. The PTV and ISQ were measured along four directions (buccal, lingual, mesial, and distal directions) in all specimens. The PTV and ISQ exhibited a highly negative correlation when the fixture was vertically inserted. Compared to the implants inserted vertically and at the distal subcrestal position, the fixture with a greater tilt and inserted at the mesial supracrestal position had a lower stability. The PTV and ISQ of the tilted implants were affected by the measurement direction, inserted angulation and depth.
