Evaluation of Accuracy of Immediate Dental Implant Placement Using Stereolithographic Surgical Stent

Background The success of implant therapy depends primarily on appropriate treatment planning and properly performed implant placement surgery, this can be achieved by means of surgical guide stents which are designed in conventional methods or by stereolithography. The aim of the study Evaluation of the accuracy of immediate implant placement using stereolithographic surgical stent. Materials and methods Ten implants were placed in patients having fresh extracted socket, implants were placed using stereolithographical design of surgical stent then measuring the deviation between the planned implant position before the surgery and the actual position of the placed implant after surgical procedure using cone beam computed tomography CBCT. Clinical assessment was done including implant primary stability, implant mobility, periimplant probing depth, sulcus bleeding index and bleeding on probing. Also radiographical evaluation was done to measure bone density and marginal bone height around implants. Assessment of implant distance to the maxillary sinus was also done by measuring the distance between implant planned and maxillary sinus by preoperative CBCT planning then measuring the actual placed implant distance to the maxillary sinus by postoperative CBCT. Results Pain and edema decreased gradually throughout the follow up period. All implants showed both clinical and radiographical success. Stereolithographic stent shows minimal deviation between planned and actual placed implants. Conclusions Immediate implant placement is a successful treatment option for restoring hopeless tooth, The guided surgery is a new modality for safe and easy implant insertion and using a stereolithographic stent for immediate implant placement is a good tool for that with an excellent outcomes.
