项目介绍
牙周维护治疗（SPT）在一般公立医院参考费用约¥140-480，三甲医院参考费用约¥200-600，常用于相关诊断评估与就医安排，费用随医院及地区有所差异。
主要用途
SPT is the cornerstone of post-active periodontal therapy care. Its primary purposes are: preventing recurrence/progression of periodontitis, maintaining achieved periodontal health and tooth/implant longevity, controlling subgingival biofilm and inflammation, enabling early detection of disease reactivation or new lesions, and supporting patients with systemic risk factors (e.g., diabetes, cardiovascular disease). It is indicated for all patients with a history of chronic or aggressive periodontitis, peri-implant mucositis/peri-implantitis, or significant periodontal risk factors.
正常值范围
Periodontal Maintenance Therapy (SPT) is not a laboratory test with numerical 'normal ranges'; it is a clinical, non-invasive, long-term care protocol. Key clinical parameters monitored during SPT include: probing depth (PD) ≤3 mm, clinical attachment level (CAL) stable (no further loss), bleeding on probing (BOP) <10–15% of sites, plaque control record (PCR) <20–30%, no suppuration, and radiographic bone level stability. These reflect periodontal health maintenance—not quantitative lab values.
偏低可能原因
N/A — SPT is a therapeutic procedure, not a measurable biomarker test; thus, 'low values' do not apply. However, suboptimal outcomes (e.g., high BOP%, deep PDs, or CAL loss) may result from: inadequate patient oral hygiene compliance, infrequent SPT intervals (>3–4 months), undiagnosed systemic conditions (e.g., uncontrolled diabetes), smoking, or residual subgingival calculus/biofilm.
偏高可能原因
N/A — SPT has no 'high values'. Clinical deterioration (e.g., elevated PD, increased BOP%, progressive CAL loss) may be caused by: poor adherence to maintenance schedule, persistent microbial dysbiosis, untreated peri-implantitis, genetic susceptibility (e.g., IL-1 polymorphism), or medication-induced gingival overgrowth (e.g., phenytoin, nifedipine).
