Clinical Efficacy Analysis of Guided Tissue Regeneration Combined with Microscrew Implant Anchorage Technique in the Treatment of Periodontitis with Malocclusion.

Objective: We aimed to explore the efficacy of guided tissue regeneration (GTR) combined with microscrew implant anchorage technique in treating patients with periodontitis and malocclusion.

Methods: Sixty patients with periodontitis accompanied by malocclusion were randomly assigned to either the control group (n = 30, receiving GTR combined with traditional orthodontic treatment) or the observation group (n = 30, receiving GTR combined with microscrew implant anchorage technique). Periodontal indicators [gingival index (GI), sulcus bleeding index (SBI), plaque index (PLI), probing depth (PD), and clinical attachment level (CAL)], chewing function (biting force, chewing efficiency), dental esthetics [pink esthetic score (PES)], as well as interleukin-6 (IL-6), matrix metalloproteinase-8 (MMP-8), and transforming growth factor-β (TGF-β) levels in gingival crevicular fluid (the gingival crevicular fluid was collected from three non-adjacent periodontitis sites) were measured in both groups. The efficacy and complications were also compared.

Results: Six months after treatment, the observation group exhibited lower GI, SBI, PLI, PD, and CAL values, and improved bit force, chewing efficiency, and PES than the control group (p < .05). Six weeks after treatment, the observation group showed reduced IL-6 and MMP-8 levels in gingival crevicular fluid and increased TGF-β levels than the control group (p < .05). Additionally, the observation group exhibited higher overall treatment efficacy than the control group (p < .05).

Conclusion: GTR combined with microscrew implant anchorage yields superior therapeutic outcomes in patients with periodontitis and malocclusion. This approach effectively improves periodontal health, optimizes the local periodontal microenvironment, enhances masticatory function, and promotes dental esthetic outcomes.
