Comparison of the biomechanical effect of distal implants placed at different angles in the all-on-four technique: A nonlinear finite element analysis.

Introduction: The "All-on-four" technique addresses this by placing two vertical implants in the anterior region and two posterior implants angled up to 45°. This study evaluates stress distribution on bone, implants, abutments, gingiva, and prostheses based on posterior implant angulation, using both standard and angled neck implants. Additionally, angled neck implants were used alongside standard implants.

Bupivacaine vs. lidocaine: a comparison of local anesthetic efficacy in impacted third molar surgery.

Objectives: The aim of this study was to compare the anesthetic efficacy, the duration of anesthesia, and the postoperative analgesia of lidocaine and bupivacaine and to determine any difference in hemodynamic parameters in patients who required impacted third molar removal.

Materials And Methods: Thirty-eight patients between the ages of 18 and 40, with no systemic disease, were included in the study, with an indication of impacted lower third molar extraction. One of two local anesthetic agents (Marcaine and Jetokain Simplex) was randomly selected for tooth extractions.

A stepped approach for the management of symptomatic internal derangement of the temporomandibular joint.

Background: Internal derangement is the clinical and pathological condition of disc displacement of the temporomandibular joint. Management of these cases involve conservative and surgical treatment options. Minimally invasive surgical procedures namely arthrocentesis and arthroscopy are promising techniques in the management of internal derangement.

Lidocaine versus mepivacaine in sedated pediatric dental patients: randomized, prospective clinical study.

Unlabelled: Dental anxiety is usually seen in the pediatric patients. specially in the case of minor oral surgical procedures and exodontia, cooperation of the patients and their families with the dentist will lead to superior treatment outcomes. Pain control is important in dentistry.
