The intra-articular injection is considered the first line of minimally invasive treatment in temporomandibular joint with internal derangement (TMJ-ID) patients who do not respond to conservative treatment. The single-needle technique arthrocentesis has emerged to add reliability, convenience, ease the performance of the procedure, and eliminate the need for multiple punctures the Aim of this study is to assess clinical applicability and therapeutic outcomes of computer guided single needle arthrocentesis with platelet rich plasma using Shepard's cannula, in comparison with conventional free-hand technique, in the management of disc displacement with reduction of the TMJ.
A total of 24 patients with a magnetic resonance imaging (MRI) diagnosis of reducing disc displacement will be included and assigned randomly into one of two groups. Computer-guided arthrocentesis with PRP will be performed on patients in the study group using the single needle technique by Shepard cannula technique; while the conventional free hand technique will be performed in the control group. Procedure-related parameters will be assessed, while Clinical evaluation will be conducted on day 1, 1 and 3 months postoperatively.

objective assessment of joint function and mandibular excursion
Clinical evaluation will be based on the Helkimo's clinical dysfunction index (Di), which is a part of the Helkimo index that provides an objective assesment of joint function and mandibular excursion. All patients will be assessed immediately post-operative, 1 and 3 months. Postoperative clinical evaluation values will be compared to the preoperative baseline preoperative values.
Time frame: 3 months
Duration of the Operation
Total procedural time consumed starting from the application of topical antiseptic up to the end of the procedure will be measured and compared between both groups. In the Computer-Guided group, the time for needle injection will be further computed to determine the actual injection time in the procedure bar from the guide installation time and patient preparation.
Time frame: intraoperative
