A comparison of two- and one-stage guided tissue regeneration approaches Summary in orthodontic therapy

Abstract

Relevance. Changes in periodontal tissues accompany orthodontic tooth movement, and if treatment planning and prognosis are not adequately comprehensive, problems may result. To increase the potential of orthodontics when there is insufficient bone and gingival volume, augmentation procedures are employed.

Purpose of the study: The goal of this study is to examine two-stage and one-stage approaches for increasing the periodontal phenotype.

Materials and Methods. PGingival recession depth, vestibula depth, attached gingival breadth, and colorimetric probes were used to assess patients' periodontal biotype. Axial and sagittal projections of CBCT were assessed at 3, 6, and 8 mm from the cementoenamel junctio n (CES).

Results. Following both procedures, the gingival biotype altered; the one-stage technique produced a medium gingival biotype, whereas the two-stage technique produced a thick gingival biotype. The thickness of the vestibular bone plate can expand by up to 2 mm at one stage and by up to 2 mm and more at two stages when bone volume and gingival thickness increase.

Conclusions. One-stage augmentation of gingiva and bone tissue can shorten treatment duration, minimize discomfort, and minimize problems.
