Purpose: We made a hypothesis that the implant stability with different insertion angles and in different measuring sites was different.
The purpose of this study is to examine the hypothesis.
Materials and Methods: The implants used in this experiment had internal submerged tapered design (BIOTEMⓇ implant). Thirty implants
were used. Five D3 artificial block bone models (OSSTEM) were used. Abutments (BIOTEMⓇ implant) with 5 mm length were
used. We inserted the implants in three different angles: 0, 15, and 30 degrees. Inserting the implants, we measured the insertion torques
of the implants. We measured the stabilities of the implants in three different sites. In the implants with 15 degrees insertion angles, we
measured the stabilities of the implants in two measuring sites.
Results: We compared insertion torques of implants with different insertion angles, and stabilities of implants and abutments in different
measuring sites. There are statistically significant differences in insertion torques and stabilities.
Conclusion: When we measure RFA, insertion torque, and PTV, we should measure them several times in different sites and carefully
take the scores. (JOURNAL OF DENTAL IMPLANT RESEARCH 2012;31(2):49-53)
