Terms & Conditions of Use

Additive manufacturing dental implants performed comparably to commercial options. This 3D printing technology shows promise as an alternative for fabricating osseointegrated implants, even when facing peri-implantitis challenges.

Area of Science:

Biomaterials Engineering
Dental Implantology
Periodontology

Background:

Dental implant use is rising globally, leading to increased treatment complications like peri-implantitis.
Peri-implantitis poses a significant challenge in modern restorative dentistry.
Evaluating novel implant designs is crucial for improving patient outcomes.

Purpose of the Study:

To compare the clinical performance of additive manufactured (3D printed) titanium implants against commercially available implants.
To assess implant behavior under peri-implantitis conditions.
To evaluate the potential of additive manufacturing in fabricating osseointegrated dental implants.

Main Methods:

Eighty implants with varied surface treatments (including 3D printed) were placed in minipig mandibles.

Peri-implantitis was induced using cotton ligatures on one side of the mandible.

Histometric analysis assessed marginal bone loss and Bone-to-Implant Contact (BIC).

Main Results:

No statistically significant difference in marginal bone loss was observed between the implant groups (p>0.05).
The Noble Biocare Active (B) group exhibited the highest percentage of Bone-to-Implant Contact (BIC).
Additive manufactured implants demonstrated performance similar to commercial implants across all analyses.

Conclusions:

Additive manufactured implants show comparable results to commercially available options in this minipig model.
3D printed titanium implants represent a viable alternative for fabricating osseointegrated dental implants.
Further research can explore the long-term efficacy of additive manufactured implants in preventing peri-implantitis.
