The Effect of Coronal Implant Design and Drilling Protocol on Bone-to-Implant Contact: A 3-Month Study in the Minipig Calvarium
Abstract
:1. Introduction
2. Materials and Methods
2.1. Surgical Procedure
2.2. Histological Processing and Analysis
- The implant shoulder
- The apical end of the implant
- The coronal end of the flute
- The apical end of the flute
3. Results
4. Discussion
Limitations
5. Conclusions
- The BIC was not affected by the drilling protocol.
- Flutes located at the implant coronal aspect significantly impaired the crestal BIC.
- Multiple shallow microthreads were associated with a greater crestal BIC.
- Further studies should be conducted to confirm the above findings.
