Summary
Cuspal inclination generates the most torque on dental implants, followed by horizontal implant offset. Understanding these factors aids in clinical diagnosis and treatment planning for better implant outcomes.
Area of Science:
- Dental Implantology
- Biomechanical Engineering
- Prosthodontics
Background:
- Dental implant stability is crucial for successful restoration.
- Understanding biomechanical forces on implant components is essential for long-term success.
- Previous research has not comprehensively evaluated torque variations across multiple implant parameters.
Purpose of the Study:
- To comparatively evaluate torque generated at the gold screw, abutment screw, and implant.
- To determine the influence of cuspal inclination, implant inclination, and horizontal/vertical implant offset on torque.
- To provide a practical guide for clinical diagnosis and treatment planning in implant dentistry.
Main Methods:
- Torque was calculated for the gold screw, abutment screw, and implant.
- Parameters evaluated included cuspal inclination, implant inclination, and horizontal/vertical implant offset.
- Comparisons were expressed as a percentage of change from a standard maxillary implant/prosthesis configuration.
Main Results:
- Cuspal inclination was found to produce the most significant torque.
- Maxillary horizontal implant offset resulted in the second highest torque.
- Implant inclination and apical implant offset generated minimal torque.
Conclusions:
- Cuspal inclination is a primary factor influencing torque in dental implant systems.
- Maxillary horizontal implant offset also contributes significantly to torque generation.
- These findings offer valuable insights for optimizing dental implant placement and restoration design.
