Adhesive bridge-like prostheses (ABP) with photocomposites and fiberglass elements that have high aesthetic and strength characteristics are widely used to restore the integrity of the tooth row. The purpose of the study was to determine the clinical efficacy of adhesive bridges in order to restore the integrity of the tooth row to an advanced clinical evaluation system in a timely manner. Material and methods. We examined 59 persons aged 22-54 with small inclusions in the lateral part of the tooth row with a length of not more than one missing tooth. For these patients we made 59 adhesive bridge implants by direct method using ENAMEL plus HRi Function, GDF, nanoproduct material, with high hardness and wear resistance and three impregnated non-polymerized fiberglass tapes Dentapreg Splint RFM, Advanced Dental Material, with dimensions of 0.3x3.0 mm, horizontally. The first group included 29 patients with 29 AMPs, for the manufacture of which, in classical approaches, secondary cavities in the middle depth of II class were formed on Blake with a chewing surface. The second group comprised 30 persons with 30 AMPs with formation of the cavities in the supporting teeth on their surfaces with converging walls in the dentin, pivotal in the enamel and additional horizontal hollows in the dentin. Clinical evaluation of the prosthesis was carried out the next day and 24 months after the developed system. Results and discussion. The next day after making, all 59 adhesive bridge-like prosthetics (100%) were in an acceptable condition and classified as "Excellent" (grade A). 24 months later, during the examination of patients in Group I, 6 fractures were identified (26.1% of the number of AMF in patients in this group). These dentures received 30 points each, they were categorized "Inappropriate" (grade D). Of the aforementioned number of prosthetics, 5 (21.7%) and 3 other prostheses (13.0%) had a violation of fixation, that is, in general, such AMP was 8 (34.8%), but only 3 (13.0%) received 4 points and category "Acceptable" (score C). In 5 prostheses (21.7%) we found chipped teeth in artificial teeth. In 4 AMP (17.4%) there was a crack in the material of an artificial tooth; 6 prostheses (26.1%) had defects of the regional adjoining. All prostheses with disabilities received 4 points for each violation and category "Acceptable" (score C). With insignificant acceptable deviations, in particular, border colorings, 12 AMPs (52.2%) were determined. These dentures received 1 point, they deserved the category "Acceptable" (score B). The highest category "Wonderful" (score A) was exposed to only 3 prostheses (13.0%) in excellent condition without any deviations, i.e. clinical efficacy was low. In patients of the second group, the fracture was defined in 2 prostheses (7.1% of the number of dentures in patients in the group during this period), the condition of these dentures was inappropriate, they received 30 points and D was assessed. Of the substantive but acceptable deviations in 4 AMIs (14.3%) were found chipped material in artificial teeth; in 2 prostheses (7.1%) defects of boundary adherence were established. The AMP with the set deflections received 4 points for each and the category "Acceptable" (score C). Of the minor deviations in 4 prostheses (14.3%), the border color was found. The dentures received 1 point and they were exposed to the category "Acceptable" (score B). In general, the significant deviations with the category "Acceptable" (score C) and the minor deviations with the category "Acceptable" (score B) had 8 AMPs (28.6%). 18 prosthetics (64.3%) received the highest category "Wonderful" (score A) in this group, which is 6 times more than in the other group. Conclusions. The preparation of cavities in the supporting teeth with converging walls in the dentin, pivotal in the enamel, with additional deepening and horizontal stacking of the three fiberglass tapes, allows us to make high quality AMF from the nanofoil composites with a direct method to restore the integrity of the tooth rows with small inclusions in the lateral section. Clinical results in the 24-month period showed a fairly high efficiency of these adhesive bridge-like prosthetics.
