Dental implants have transformed modern dentistry, offering patients a reliable solution for replacing missing teeth. But anyone who has undergone implant surgery knows that the recovery process can be uncomfortable. Postoperative pain, swelling, and delayed healing are some of the biggest concerns for both patients and clinicians.
Traditionally, these issues are managed with painkillers and anti-inflammatory medications. While effective, these drugs can bring side effects like stomach irritation, allergic reactions, or even long-term dependency if overused. That’s why researchers have been exploring safer, non-drug alternatives to support recovery.
A new randomized controlled trial published in Cureus (June 2025) suggests that ozone therapy may offer just that.
What the Study Looked At
Researchers led by Abhinav Shekhar and colleagues evaluated 84 patients undergoing delayed dental implant placement. Participants were split into two groups:
- Ozone group: received ozonated saline during drilling, ozone gas applied inside the implant site, and a small ozone injection around the surgical area.
- Control group: received the standard protocol with sterile saline.
Both groups had implants placed using the same brand, torque, and suturing methods.
Researchers then measured:
- Pain levels using the Visual Analog Scale (VAS) at 24 and 48 hours post-surgery.
- Soft tissue healing using the Landry Healing Index at 7 and 14 days.
Outcome assessors were blinded to reduce bias.
The Results Were Striking
Patients in the ozone group experienced:
- Less pain
- At 24 hours: significantly lower pain scores compared to the control group.
- At 48 hours: continued pain reduction.
- By day 7: pain levels in the ozone group had nearly resolved, while the control group still reported discomfort.
- Better soft tissue healing
- Day 7: improved scores for reduced redness, swelling, and faster closure of incision sites.
- Day 14: most ozone-treated sites had reached “excellent” healing, with healthier tissue and quicker epithelialization.
Statistically, the differences between groups were highly significant (p < 0.001).
Why Ozone Works
Ozone (O₃) isn’t just known for protecting Earth’s atmosphere — it also has powerful antimicrobial, anti-inflammatory, and regenerative properties in medicine. In dentistry, ozone has been used to:
- Kill bacteria and reduce infection risk.
- Improve oxygenation of tissues, speeding up wound repair.
- Stimulate immune responses and growth factors that promote healing.
By controlling inflammation and supporting regeneration, ozone therapy may create the ideal environment for implant recovery.
What This Means for Patients and Dentists
This study suggests that ozone therapy could be a valuable adjunct to standard implant protocols, offering:
- Faster recovery times.
- Reduced need for pain medications.
- Better patient comfort and satisfaction.
While the trial had some limitations — such as a relatively short follow-up period (14 days) and being conducted at a single center — the findings add to growing evidence supporting ozone in dental care.
The Bottom Line
For patients facing dental implant surgery, ozone therapy may soon become part of routine postoperative care. Its ability to reduce pain and accelerate healing makes it a compelling, non-drug option to improve outcomes.
As the authors conclude:
“Ozone therapy seems to be a very good adjunct in relieving postoperative pain and promoting the healing of soft tissues.”
Further long-term, multi-center studies will help solidify ozone’s role in implant dentistry — but for now, this trial is a strong step forward.
