Surgical intervention aims to stop the progression of the pathology through the removal of the tissue macroscopically affected (resective surgery,sequestrectomy, debridement).\n\nThese surgical procedures are classically performed by the use of handpiece burs, but due to the advent of piezoelectric surgery in dentistry, a comparison of the two techniques is required\n\nAt present there are no randomized clinical trials designed to compare the postoperative discomfort of the two previously described techniques in the treatment of MRONJ. Therefore, the aim of this study is to evaluate the postoperative discomfort in a group of patients undergoing surgical therapy for MRONJ with piezoelectric instruments compared to a control group undergoing MRONJ surgical therapy with traditional rotary instruments.\n\nMETHODS This is a randomized clinical trial conducted in patients diagnosed with MRONJ who require surgical therapy.\n\nPatients will be recruited and evaluated for a period of 24 months. Follow-up of patients enrolled in the study will last 12 months. Specifically, once patients diagnosed with MRONJ requiring surgical therapy are identified, surgery will be scheduled within 1 month, then follow-up visits will be conducted at 1, 2, 3 weeks and 3, 6, 12 months after surgery.\n\nPatients enrolled and randomized into one of the two groups will all undergo necrotic bone removal surgery by the same operator with decades of experience in treating MRONJs. Marginal bone resection surgery will be performed using rotary or piezoelectric instruments. Both surgical procedures involve wound closure by first intention healing using sutures. Each bone block removed will undergo histologic examination for diagnostic confirmation of osteonecrosis. Postoperative instructions will be explained to patients, and sutures will be removed at 7 or 14 days after surgery.\n\nEach patient will be asked for a 3D radiologic exam (CT or CBCT) at least 12 months after surgery in order to asses the",[27,28,29],"Bisphosphonate-Associated Osteonecrosis of the Jaw","Osteonecrosis of the Jaw","Osteonecrosis Due to Drug",[31,32,33],"MEDICATION RELATED OSTEONECROSIS OF THE JAW","SURGICAL TREATMENT OF MRONJ","MRONJ","NOT_YET_RECRUITING","2025-09-17",{"date":37,"type":38},"2025-09-22","ACTUAL",{"date":40,"type":21},"2025-12-01",{"date":42,"type":21},"2027-09-01",{"name":44,"class":45},"Fondazione Policlinico Universitario Agostino Gemelli IRCCS","OTHER",1,{"id":48,"slug":49,"hasResults":11,"nctId":50,"briefTitle":51,"officialTitle":52,"acronym":4,"eligibilityCriteria":53,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":54,"targetDuration":4,"studyType":56,"phases":4,"briefSummary":57,"conditions":58,"keywords":4,"overallStatus":61,"whyStopped":4,"lastUpdateSubmitDate":62,"lastUpdatePostDateStruct":63,"startDateStruct":65,"completionDateStruct":67,"leadSponsor":69,"locationsCount":46},"100551260","medication-related-osteonecrosis-of-the-jaws-mronj-in-a-cohort-of-patients-treated-by-antiresorptive-drugs-100551260","NCT06457776","Medication Related Osteonecrosis of the Jaws (MRONJ) in a Cohort of Patients Treated by Antiresorptive Drugs","Medication Related Osteonecrosis of the Jaws (MRONJ) in a Cohort of Patients Treated by Antiresorptive Drugs: a Cohort Prospective Study","Inclusion Criteria:\n\n* Patients with specific prescription to initiate therapy with antiresorptive drugs\n\nExclusion Criteria:\n\n* Previous Head and Neck Radiotherapy",{"count":55,"type":21},126,"OBSERVATIONAL","The objective of this prospective observational study is to investigate the incidence of Medication Related Osteonecrosis of the Jaws (MRONJ) in patients receiving antiresorptive drugs for oncohematologic reasons during a 5-year follow-up.
