Disc repositioning for TMJ internal derangement is established procedure with variable success and means of fixation. The purpose of this study is to assess the outcome of using temporomandibular joint (TMJ) arthroscopy disc repositioning with retrodiscal contracture as a minimally invasive surgical treatment for TMJ internal derangement (ID). Materials and Methods: 25 patients, were treated in the period from 2015-‌ 2017. All patients were evaluated for changes in preoperative versus postoperative clinical assessment through visual analog scale score (VAS), maximum interincisal opening distance, Joint loading Sign, joint noise and pain, muscle pain, diet and medication intake. Methods of Data Analysis: All patients were followed up for 1 year after treatment. Statistical analyses included the Student t test and Chi square test to determine if there were significant differences in preoperative and postoperative assessments. Results: 25 patients (32 TMJ), the mean age was 39 years; 21 were female and 4 male. 13 classified as Wilkes II, 19 as Wilkes III. The success rate was 72% based on improvement of joint pain. The study showed statistically significant improvement in all outcome variables except muscle pain. Conclusion: Clinical outcome data presented show that TMJ arthroscopy disc repositioning with retrodiscal contracture is an effective, predictable surgical treatment.

Patients and methods: Twenty-four patients were selected from those attending outpatient clinics of the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry for boys Al-Azhar University, presented with maxillary posterior molar indicated for extraction. All selected patients randomly allocated into two equal groups. group one is a Study group, extraction one of maxillary posterior teeth with application of Bio-Oss® and platelet-rich fibrin membrane for ridge preservation. Group two is a Control group, extraction one of maxillary posterior teeth without any grafting material. The measurements were performed includes: distance from the bone crest (BC) to the sinus floor (SF), distance from SF to the sinus roof (SR) to evaluate maxillary sinus and alveolar crest dimensional changes after posterior maxillary tooth extraction in both groups. Results: There was statistically significant decrease in alveolar ridge height (BC to SF) and significant increase is sinus vertical dimension (SF to SR) for both groups. while there is a significant increase of bone quantity in the study group than the control group. Conclusion: It can be concluded that tooth extraction in the posterior maxilla may lead to sinus pneumatization and crestal bone loss, using Bio-Oss® and platelet-rich fibrin seemed to reduce sinus pneumatization along with minimizing crestal bone resorption.

This disorder is known to be multifactorial. There are wide varieties of treatment for the TMD, including non-surgical and surgical treatments. Recently, the low-level laser therapy (LLLT) has been used as a treatment modality to the TMDs. AIM: The aim of this study was to compare and evaluate the effect of low-level laser therapy (LLLT) versus sodium hyaluronate with arthrocentesis in management symptoms of temporomandibular joint disorders (TMD). PATIENTS AND METHODS: This was a clinical randomized controlled study conducted on 40 patients with a total of 40 joints (3 males and 37 females) diagnosed with TMDs. The patients were randomly divided into 2 groups. Group A (Laser group) received active application of the low-level laser therapy (LLLT). Group B (Arthrocentesis group) received combined arthrocentesis and low molecular weight sodium hyaluronate intracapsular injection. RESULTS: When comparing the two groups, there were no statistically significant differences; between group A and group B regards changes in measuring pain on visual analogue scale (VAS) and maximum painless opening from pre-operative till post-operative at one month. While, there were statistically significant differences; between the two from pre-operative till post-operative at three months follow up periods.

Purpose: to assess and compare changes in height and percentage of Puerarin versus simvastatin as osteoconductive materials following sinus augmentation. Basic procedures: twenty patients with edentulous posterior maxilla were selected and equally grouped into 2 groups. Both groups underwent antral augmentation using either Puerarin on Fisiograft sponge carrier graft (group A) or combination of simvastatin and β-TCP (group B). The amount and percentage of bone graft were evaluated radiographically. Assessment occurred at period intervals 1-week and 6-month postoperatively. Data were presented as mean and standard deviation (SD) values. For non-parametric data, Mann-Whitney U test was used to compare between the two groups. Qualitative data were presented as frequencies and percentages. Fisher’s Exact test was used for comparisons between the groups. The significance level was set at P ≤ 0.05. Main finding: there was decrease in the amount and percentage of bone graft height by 2.5 mm, 19.7% (for Group A) and 3.2 mm, 22.4% (for Group B) at the end of the 6 months period without significant difference in both group (P-value = 0.054, Effect size = 0.919) and (P-value = 0.151, Effect size = 0.678), respectively.

A total of 108 joints were subjected to first diagnostic arthroscopic TMJ lysis and lavage. Those procedures were done in Department of OMFS, Cairo University, Cairo Egypt.This study was assessed through correlating preoperative TMJ diagnosis based on MRI interpretation, to perioperative TMJ diagnosis based on arthroscopic findings. Results of investigation: This study revealed that Preoperative diagnosis, based on MRI assessments, came into co-ordinance with arthroscopic findings in 73 (67.51%) studied joints but were different in the remaining 35 (32.41%) joints.

Cone beam computer tomography was done for sites that need implant placement preoperatively. Xenogeneic bone was used for grafting deficient horizontal alveolar ridge sites using the flap technique in 6 areas and using the subperiosteal tunneling technique in another 6 areas for future implant placement. Cone beam computer tomography was done for grafted sites immediately postoperative and 6 months postoperative. Results: This study was conducted on 10 patients and included 12 implant sites. No complications related to bone grafting were found and there was an adequate clinical prognosis.
