The applicability of a new wound expander for surgical operations in the oral cavity in the experiment

An experimental study of the innovative wound expander applicability for surgical operations in the oral cavity was performed. For comparative analysis, 40 experimental models were divided into 4 groups depending on the use of auxiliary devices: Farabef hooks, VICRYL 3/0 suture material (ETHICON, USA), innovative wound expander, without the use of additional materials and tools. An experimental simulation of the operation of dental implantation in the area of the included dentition defect (Kennedy class III, IV), as one of the most frequent outpatient surgical operations in the oral cavity, was performed. The results of the study prove the innovative wound expander applicability for surgical operations in the oral cavity and its obvious advantages over existing analogues: providing adequate access, reliable, stable fixation of the wound edges, minimal injury to the surrounding tissues, protecting the edges of the operating wound from possible injury during surgery, lightweight, durable design, individually adapted to the anatomical features of the operated area, made of biologically inert materials, safety and ease of operation, affordable price, no need for an assistant to contact the operating field. Therefore, it is reasonable to conduct further clinical approbation and introduce the device into the practice of dental surgeons and maxillofacial surgeons.
