Purpose:
To evaluate the effect of time-to-loading on trabecular bone around single-tooth dental implants using numerical solutions based on computer models.
Materials And Methods:
A global model with a coarse mesh carrying a Straumann dental implant (043.033S; Institut Straumann, Basel, Switzerland) was created. A region of interest in trabecular bone was defined to study a localized part of the global model with a refined mesh. Time-to-loading submodels to simulate 2h, 4 days, 1, 4, 6 and 12 wks of trabecular bone-healing status were designed and created. Bone types were considered in the simulation by different elastic bone properties. A 100-N oblique static load was applied. Maximum and minimum principal stresses were calculated and visualized.
Results:
Bone types with higher elastic moduli experienced higher stress levels. Changes in the quality and quantity of bone at the bone-implant interface did not affect the overall stress distribution. Peri-implant bone with a higher elastic modulus preserved the stress increase at the implant-bone interface.
Discussion:
Reduced bone contact may not have a prevailing effect over bone quality and quantity on stress generation at the peri-implant bone.
Conclusion:
Time-to-loading of single-tooth implants may not differ in terms of load distributions in neighboring peri-implant bone.
