Summary
This study presents bone-type specific drilling for a novel tapered dental implant, achieving optimal primary stability. This research also introduces a finite element model to predict implant stability.
Area of Science:
- Biomaterials Science
- Dental Implantology
- Biomechanics
Background:
- Primary mechanical stability is crucial for dental implant success, influencing secondary stability and long-term outcomes.
- Factors affecting primary stability include bone quality/quantity, implant design, and surgical technique.
- Tapered implant designs offer advantages in achieving primary stability, especially in challenging bone conditions like soft bone or immediate extraction sockets.
Purpose of the Study:
- To introduce and evaluate bone-type specific drilling procedures for a novel Straumann bone level tapered implant.
- To ensure maximum insertion torque values remain within a clinically relevant range (15-80 Ncm).
- To develop an in silico model for predicting the primary stability of tapered implants.
Main Methods:
- In vitro testing using variable-density polyurethane foam blocks.
- Ex vivo evaluation on explanted porcine ribs (bone type 3).
- In vivo assessment on porcine mandibles (bone type 1).
- Development of a finite element analysis (FEA) model.
Main Results:
- Bone-type specific drill procedures consistently achieved good primary stability across all tested materials and bone types.
- Insertion torque values were maintained within the target range of 15-80 Ncm.
- The developed FEA model demonstrated capability in predicting primary stability.
Conclusions:
- Novel tapered implant combined with bone-type specific drilling ensures good primary stability in various bone types.
- The study successfully validated the biomechanical behavior of the implant-drilling system.
- An in silico model was created to predict primary stability, aiding in clinical application planning.
