Microecology of the oral mucosa at the stage of prosthetic rehabilitation in patients with acquired defects of maxilla

The morbidity of malignant neoplasms of the maxillofacial area has an annual constant increase. Surgical treatment is one of the therapy versions. The acquired defect is the result of such treatment, which also requires the reconstructive and prosthetic treatment. Production of a hollow acrylic obturator is widespread and available option of prosthetic rehabilitation after resection of maxilla. One of this treatment characteristic is the large contact area of the obturator surface to the oral cavity mucosa, and the sutural connection on the basis. This connection is a cluster of food remainders and pathogenic microflora of the oral cavity. The oral cavity mucosa is the primary place of contact not only with the aggressive elements of dental engineering materials, antigens, but also to waste products of microorganisms, which are located on prosthetic constructions. The sutural connection requires additional hygienic measures to clean the obturator for the patient. Thus, acrylic hollow obturator with sutural connection substantially reduces the level of hygiene in this patients group and promotes the accumulation of aggressive microorganisms. After prosthetic rehabilitation it can result to damage of oral microbiocenosis and development of inflammatory accidents. We developed a processing technique of a hollow obturator without sutural connection on the basis.
