Dental Implant Healing With TNF-Alpha Inhibitors
Sponsor:

University of Pennsylvania

Information provided by (Responsible Party):

Katherine France

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.

Criteria
Inclusion Criteria
  • * Over the age of 18
  • * Require placement of implants to assist with dental restoration.
  • * Half of the patients (15) will be recruited with the key criteria of a TNF-alpha inhibitor medication that they have been taking consistently without dose adjustment or other changes for at least 6 months. The other half will be recruited without a target medical condition but will be recruited to match the patients taking TNF-alpha inhibitors in age and gender.
  • * All patients will be medically fit to withstand implant placement as judged by best practice applied by the study team.
  • * The patients will be required to read and speak English
  • * All patients must either provide their own independent consent for medical procedures or to attend study visits with a surrogate decision maker.
Exclusion Criteria
  • Patients will not be excluded on the basis of age (within the adult population), race, economic status, sex or gender, or other demographic factors. Patients will be excluded if
    • * They have periodontal disease (periodontal pockets above 4mm in the applicable arch or radiographic evidence of horizontal bone loss more than mild severity)
    • * There is other evidence of pathology in the treated arch on pre-treatment review including radiographs, such as any evidence of cyst or tumor formation in the mandible.
    • * They have uncontrolled diabetes (HbA1c \>8.0) as confirmed by evaluating labs taken on anyone with diagnosed diabetes in the 6 months before the study enrollment.
    • * They have history of head and neck radiation for any reason
    • * They are taking any antiresorptive or antiangiogenic agents for any reason including osteoporosis, multiple myeloma, bone metastasis of other primary cancers
    • * They are unable to seek outpatient medical care or are not medically fit to withstand implant placement, including those with critical findings or lab values. Medical exclusion of patients will be completed by the investigators based on standard of care for surgical procedures in dental medicine and based on specific implant guidelines.
    • * Patients who have routinely used tobacco or tobacco products in the last 1 year will be excluded, as tobacco use is a known contributor to poor prognosis after implant placement. For this reason, dental implant placement is only recommended in patients who have quit or never used tobacco products.
    • * Pregnant women are unlikely to meet inclusion criteria as dental implant placement is considered an elective procedure and typically deferred in dentistry until after delivery.
