Signs Of Dental Bone Graft Failure

Are you considering a dental bone graft surgery? It’s important to be aware of the potential risks and complications that may arise. Infections can occur after such surgeries, and if left untreated, they can lead to a complete nightmare, including the loss of the grafted material or the implant placement. In this article, we will discuss the signs of dental bone graft failure and the importance of proper antibiotic therapy to prevent complications.

The Risk of Infections in Oral Surgery

The oral cavity is one of the most contaminated areas of the human body, meaning that the chances of infection are quite significant when surgery is performed. To mitigate this risk, prescribing antibiotics becomes crucial, particularly for more extensive surgeries such as complex augmentations.

Developing an Antibiotic Protocol

To prevent complications and ensure the success of your dental bone graft surgery, it’s essential to follow a well-designed antibiotic protocol. Although different protocols exist, we would like to share the one we use in our daily practice.

First and foremost, it’s important to determine if the patient has any allergies, particularly to penicillins. Allergic patients may have a higher likelihood of infection, so it’s crucial to take precautions. For patients without allergies, we typically prescribe amoxicillin plus acid clavulanic. The reasoning behind this is that in Spain, there is a higher resistance to penicillin, and associating clavulanic acid helps prevent infection.

The Timing of Antibiotic Administration

To ensure that antibiotics are effective, we recommend initiating the therapy one hour before surgery. This prophylactic approach ensures that the antibiotics are already in the patient’s bloodstream when the surgical procedure begins. The antibiotic therapy is then continued for at least seven days, although for more complex surgeries, such as bilateral sinus lifts or vertical augmentations, a 14-day course is prescribed.

Allergic Reactions and Alternative Treatments

If a patient is allergic to penicillin, alternative antibiotics must be used. For minor surgeries, such as a single implant or wisdom tooth extraction, clindamycin is typically prescribed. However, when it comes to major surgeries, where the risk of infection is higher, allergic patients are treated as if they were already infected. In these cases, we prescribe ciprofloxacin and metronidazole at specified doses.

Ensuring Patient Compliance and Managing Side Effects

When prescribing antibiotics, it is essential to educate patients on the importance of completing the full course of medication. Inadequate compliance can lead to antibiotic resistance and potential complications. Patients may experience side effects such as diarrhea due to clavulanic acid. In such cases, probiotics can be recommended to alleviate these symptoms. Female patients should also be monitored for potential candidiasis, for which fluconazole can be prescribed as a precautionary measure.


In conclusion, proper antibiotic therapy is essential when undergoing dental bone graft surgery. By following a well-designed protocol, the risk of infection and subsequent complications can be significantly reduced. Remember to consult with your dentist or oral surgeon to determine the best antibiotic regimen for your specific case.
