Oral soft tissues are critical for successful denture treatment. They provide physical support and increase retention for dentures. Evaluating soft tissue quality is indispensable when determining if a patient is suitable for dentures.

Healthy mucosa and gingiva can provide a cushioning effect against forces on the denture. If soft tissues are atrophic or too thin, the denture will directly load the bone, causing pain. Scientific evidence shows soft tissue thickness directly affects patient satisfaction.

For completely edentulous patients, the mandibular anterior ridge should have at least 3mm thick; the maxillary anterior ridge should be at least 5mm thick. Posterior areas also need adequate soft tissue support. If insufficient, the dentist can increase thickness via flap surgery.

In addition to thickness, the extent, surface texture, and resilience of soft tissues must also be evaluated. The extent determines denture border design; smooth texture is more suitable; resilient tissue provides better support. Unhealthy tissue requires pretreatment.

Denture design also considers soft tissue factors. Borders should intimately fit tissue surfaces to prevent over-compression. Base materials should have some resilience and match tissue properties. Regular recalls need to monitor soft tissue status.

Even with thorough assessment and design, soft tissue support will change during use. Necessary adjustments and recalls can ensure sustained health. Good daily hygiene and follow-up visits are key to maintaining soft tissues.

In summary, assessing and maintaining soft tissues are crucial for successful denture function and patient comfort. This requires attention and close cooperation from both dentist and patient. Only healthy soft tissues can provide reliable support for dentures.
