Purpose of the work. To dynamically compare the use of a xenogeneic collagen matrix and a soft tissue cuff reinforced with osteoplastic material (MMACM) to increase the width of the keratinized mucosa (KM) in the area of simultaneous dental implantation. Materials and methods. The study included 51 patients who underwent singlestage dental implantation. Depending on the implantation technique, the patients were divided into 2 groups: the main observation group consisted of 25 patients who, after tooth extraction, had the implant installed in the prepared bed with preliminary filling of the socket with Sensobone xenograft, after which the MMAKM was formed with subsequent fixation of a temporary crown; the comparison group included 26 patients who, after tooth extraction, had the implant installed in the prepared bed with preliminary filling of the socket with Sensobone xenograph, after which the soft tissue zone was filled with Sensobone xenograph and a temporary crown was fixed. The width of the KSO was determined from the free edge of the gum to the mucogingival junction before implantation, 3 months and one year after implantation. The study results were processed on a personal computer using the statistical package of the licensed program “Statistica, version 13” (Copyright 1984-2018 TIBCO Software Inc. All rights reserved. License № JPZ8041382130ARCN10-J). Results. It was established that the use of MMAKM provided: a reliable increase in the width of the XCO 3 months after implantation by 0.87 mm, and after a year – by 0.94 mm, which is significantly more by 1.25 mm than in the group where the xenogenic collagen matrix was used; a significant increase in the width of the CSO after one year in the area of all teeth (central incisor (CI) by 1.12 mm, lateral incisor (LI) by 0.97 mm, canine (C) by 0.92 mm, first premolar (1PM) by 1.15 mm, second premolar (2PM) by 1.05 mm, first molar (1M) by 0.68 mm), and in the group with xenogeneic collagen matrix there was a significant decrease (BR by 0.17 mm, IL by 0.16 mm, 2PM by 0.29 mm, 1PM by 0.12 mm, 1M by 0.22 mm). Moreover, the width of the CSO in both groups both before implantation and in dynamics did not depend on the jaw, and was on average 0.5 mm greater on the upper jaw than on the lower. Before implantation, the smallest CSO width in patients of both groups was in the area of the 1 PM. The CSO width does not depend on the age and sex of patients, as well as the type of teeth and jaws. During the year of observation, there were no failures of dental implantation in both groups, and the survival rate of implants one year after their installation was 100 %.
