Dental Implant Healing With TNF-Alpha Inhibitors
brief summary
The goal of this pilot study is to learn about healing after dental implant placement in patients taking a class of biologic drug called Tumor Necrosis Factor or TNF-alpha antagonist or inhibitor. The main questions it aims to answer are: Do patients taking TNF-alpha inhibitors have any complications after the placement of dental implants? Do patients taking TNF-alpha inhibitor experience increased pain after dental implant placement compared to the expected levels when healing from this procedure? Researchers will recruit patients both taking these drugs and those not taking these drugs to compare the outcomes between the two groups. Participants missing teeth will be recruited to receive dental implants to meet ideal dental status and will be followed before and after the implant placement to determine levels of health and ensure proper healing. Participants will be followed for a total of one year and follow up visits will consist of both clinical examination and radiographs (x-rays) to evaluate bone level and implant status. Participants will also be asked to rate their pain during clinic visits and at home on a diary and record the amount of pain control medication they take after the implant procedure.
detailed description
This descriptive study will recruit 15 patients requiring implant restoration as standard of care for missing teeth taking a stable dose (unchanged for 6 months or more) of a TNF-α inhibitor, regardless of the targeted disease and 15 patients requiring implant restoration not taking TNF-alpha inhibitors (30 patients total). Patients will be recruited without age restrictions or limitations on systemic medical conditions or other medications, although patients not taking TNF-alpha inhibitors will be matched via age and sex to those taking the medications. Patients with periodontal disease and smokers will not be included given the known connection between these comorbidities and compromised implant outcomes. Patients will be selected based on inclusion and exclusion criteria, consent, availability, and willingness to follow study protocols. Patients will not stop their TNF-alpha or any other medication during the study period to minimize adverse systemic outcomes.
Once enrolled, subjects will be evaluated according to medical history including reason for TNF inhibitor, demographics, and clinical and radiographic features. NobelParallel conical connection implants will be placed under standard surgical approach to confirm equanimity of experience. Nobel anatomical healing abutments will be placed above each implant and followed for 12 months according to study procedures. All patients will receive the same dental implants, specifically the NobelParallel TiUltra 3.75x11.5 implant and titanium healing abutment (see product guide attached).
Follow up appointments will assess healing including pain score and analgesic use (routine standard of care but will be recorded as part of this research study), periodontal probing, and radiographs. Radiographs will determine bone quality and quantity. Nature and frequency have been planned according to best practices, with details found below. The images proposed that are additional to routine clinical care are: CBCT immediately after implant placement, CBCT at 6 months following implant placement, periapical radiographs at 6 and 12 months after implant placement. Patient serum will be drawn at the implant placement and all follow up visits to test for complete blood count, C-reactive protein, and erythrocyte sedimentation rate to assess systemic inflammation and any changes after surgery. If patients complete all study visits, their implant placement surgical treatment will be financially covered in full. Patients will also be compensated for their time during the 3,6, and 12 month study visits, which will improve patient retention. Of these, the 3 month study visit would be routine during normal clinical care.
