The Clinical Application Of Guided Bone Regeneration Technique In The Dental Implant Restoration Of Traumatic Dentition Defect

Object:To observe the clinical effects of guided bone regeneration technique in the dental implant restoration of dentition defect patients caused by trauma.Methods:A total of25patients with bone defects in the implantation area were selected as subjects, who were included16patients with mandibular fractures, and the remaining nine cases were simple tooth and alveolar bone damage.(1) General take x-ray examination for patients are completed before implant surgery to understand the situation of. alveolar bone in the implantation area.(2) According the preoperative design to perform implant surgery.(3) Bone defects around implants were repaired by guided bone regeneration technique with bone graft.(4) Put the appropriate size membrane on the bone defect area, and over the edge of bone graft2-3mm.(5) Close the incision, general take x-ray examination and prophylactic use antibiotics.(6) Return in7-10days, check the healing of soft tissue and remove the stitch.(7)4-6months later, complete implant restoration by the implant growth, and take x-ray examination after the restoration.(8) The patients should return to take the x-ray picture every6months.Results:In this group of25patients, we implant61implants during the first surgery.When the patients return in7-10days, we found only one patient’s heal split. This patient was dentition defect caused by trauma, and with poor oral health. His problem has been solved after dressing changes. During the6-24months of clinical observation after the restoration, we find that all the implants are in good stability, the upper side functions well and the soft tissue is in good shape. The patients are all satisfied with the results and the success rate is100%. The bone tends stabilized after6months, and the bone resorption less than1mm in one year. Conclusions:(1) Guided bone regeneration technique can significantly improve the effect of bone increment in the process of traumatic dentition defect implant, and have a good stability.(2) As the GBR technique has a better effect of bone increment and can be used to treat a wide scope of symptoms, it becomes the most common supplementary means in dental implant of traumatic dentition defect.
