A big problem for obtaining aesthetic and functional results of dental treatment is the condition of the gingival papillae. The effectiveness of orthopedic interventions without high-quality correction of the marginal edge of the gums can lead to an unsatisfactory result and the occurrence of numerous complications
Materials and methods. A literature search was conducted in the PubMed and Medline databases for the period 2000-2024, for which the following keywords were used: correction of soft gingival tissues, fixed dentures, effectiveness, front group of teeth.
A general search revealed 112 sources regarding gingival margin correction in fixed dentures. The primary exclusion referred to literary sources in which the correction of the gingival margin applied to all types of prosthetics. Literary sources that contained only reference information were included in the secondary exclusion. As a result, only relevant full-text articles in professional journals remained (n=25).
The purpose of the research is to analyze the methods of gingival margin correction in orthopedic dentistry at the current stage, to formulate relevant tasks for further research.
Research results. Methods of restoration of the aesthetics of the marginal part of the gums during orthopedic treatment are divided into the following groups: plastic of soft and bone tissues; laboratory and technical procedures; use of materials for artificial gums.
It has been established that the plastic-surgical method is used for the loss of the gingival papilla, defects of the ridge of the alveolar process, asymmetric contour of the gums, and their unaesthetic shape. Correction of the gums allows to achieve satisfactory aesthetic results both at the final stage of orthopedic treatment (prosthetics with fixed orthopedic prostheses) and at the intermediate stage of temporary prosthetics with plastic fixed prostheses.
It was found that the most common methods of gingival margin correction are flap operations on the gums using the technique of lateral movement of the muco-osseous flap. These include the following types of interventions: endothelial modification from the tooth-alveolar ridge; oblique displaced flap; periosteally stimulated flap; partial or complete split flap.
The positive effect of hyaluronic acid on the healing of the gingival margin and tissue regeneration has been proven. Several researches have shown the positive effects of hyaluronic acid on gingival margin healing and tissue regeneration due to its properties to stimulate cell adhesion, migration and proliferation, mediate cell signaling. The authors indicate a better effectiveness of hyaluronic acid in relation to periodontal parameters during the correction of the marginal gingival margin.
The use of a laser scalpel is characterized by less pronounced traumatization of tissues, lower temporary costs for intervention, reduced blood loss, less pronounced signs of inflammation in the postoperative period, relative simplicity and cost-effectiveness of use.
Conclusions. To date, only a combination of various orthopedic and surgical manipulations allows to achieve an optimal aesthetic result during prosthetics with fixed dentures of the front group of teeth.
