Aim: To evaluate the neuromuscular and occlusal characteristics of the dentition in patients with complete tooth loss in one of the jaws who were fitted with temporary fixed prosthetic structures for immediate loading of dental implants. Materials and Methods: Using the method of synchromyography (Teethan system), functional parameters was analyzed in three groups of patients: with structures based on a cast beam, with a welded beam, and with polymethyl methacrylate (PMMA). Results: The results emphasize the importance of choosing the type of temporary structure depending on the functional requirements, patient characteristics, and long-term prospects for adaptation. Conclusions: The study emphasizes the importance of choosing the type of construction to ensure effective rehabilitation of patients with complete loss of teeth in one of the jaws and prevention of possible complications. The researchers recommend using cast or welded beams to achieve optimal long-term clinical results.
