Brief Summary:
Approximately 500 patients will be included in this patient registry. Data collection includes demographics, clinical data of underlying disease and use of bisphosphonates, denosumab and antiangiogenic drugs , degree and extension of osteonecrosis, osteonecrosis-specific treatment, outcomes and complications within 1 year after treatment.

Condition or disease Intervention/treatment
Medication-related Osteonecrosis of the Jaw Bisphosphonate-Associated Osteonecrosis of the Jaw Procedure: Conservative treatment Procedure: Surgical treatment Procedure: Adjuvant non-surgical treatment

Detailed Description:
Approximately 500 patients diagnosed with medication-related osteonecrosis of the jaw will be enrolled in the study. Patients will undergo standard (routine) of care treatment, either conservative or surgical or both, and followed up during one year after the initiation of the treatment. Treatment outcome (development of the condition), pain and complications will be collected and documented over the duration of the registry.

Group/Cohort Intervention/treatment

Patients diagnosed of medication-related osteonecrosis of the jaw (MRONJ). Treatment strategies vary depending on the stage of MRONJ and can be of different nature as:

Conservative treatment Surgical treatment Adjuvant non-surgical treatment

Procedure: Conservative treatment
Disinfectant mouth rinses, Antibiotic therapy, Antifungal therapy

Procedure: Surgical treatment
Superficial debridement, Complete removal of necrotic bone, Complete bone resection, When applicable revision and soft tissue coverage

Procedure: Adjuvant non-surgical treatment
Hyperbaric oxygen therapy Pentoxifylline and tocopherol Ozone therapy Low level laser therapy Pain relief Anti-inflammatory treatment Platelet rich plasma Parathyroid hormone and teriparatide Bone morphogenetic protein

Primary Outcome Measures :
  1. Treatment outcome [ Time Frame: 6 months / 1 year ]

    Compared to the baseline status of the patient's condition, the outcome will be evaluated as:

    • Worsening of the osteonecrosis (e.g. size of the lesion increased)
    • No change of the osteonecrosis
    • Reduction of the osteonecrosis (e.g. size of the lesion decrease)
    • Complete mucosa healing

Secondary Outcome Measures :
  1. Pain perception [ Time Frame: 6 months / 1 year ]
    Numeric Rating Scale

  2. Staging of osteonecrosis [ Time Frame: 6 months / 1 year ]
    Staging of osteonecrosis according to the American Association of Oral and Maxillofacial Surgeons

  3. Site and size of the lesion [ Time Frame: 6 months / 1 year ]
    Site (single vs. multiple) and size of the lesion according to Weitzman et al.
