Gingival Margin, Correction in Orthopedic Dentistry
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.

Comparative evaluation of the effect of impregnated retraction cord versus laser on gingival attachment level and pain perception following retraction for subgingival margins - A prospective, split-mouth, controlled, clinical study
Aim: To evaluate and compare the effect of impregnated retraction cord vs Laser on gingival attachment level and pain perception following retraction for subgingival margins. Settings and Design: Many methods for achieving and measuring the amount of gingival retraction in fixed prosthodontic work have been advocated. Though the gingival attachment level is crucial in Periodontology, the literature available regarding the effect of these retraction methods on the same is scarce. Hence, this clinical study was designed to compare the pain perception and amount of gingival recession when impregnated cord and laser were used for retraction. Materials and Methods: In 40 subjects (age range of 20 to 40 years) with single missing maxillary incisor, the abutments were prepared with subgingival margins, to receive a full coverage metal-ceramic fixed dental prosthesis. The gingiva was retracted on one of the abutments with impregnated retraction cord and on the other with diode laser. Gingival attachment levels were compared at six sites per abutment using superimposition of digital scans, preoperative and four weeks after cementation of final prosthesis. Statistical Analysis Used: Statistical analysis of the data for gingival recession was done using t-test. Pain perception was analysed with Chi-square test. Pain perception by patients following retraction was compared with VAS scale. Results: The average values of gingival recession on buccal side were 0.61 mm and 0.38 mm and on the palatal side were 0.58 mm and 0.35 mm for impregnated retraction cord and laser respectively. The P values of <0.01 indicated a highly significant difference between the two groups. Intragroup comparison did not show significant differences between various sites. Pain and discomfort produced by cord method was moderate in comparison with mild/no pain with diode laser and the difference was highly significant. Conclusion: Retraction cord produced more gingival recession than the diode laser, which was statistically highly significant on both buccal and palatal aspects of the teeth. Patients experience with diode laser technique was less painful in comparison with retraction cord method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
