Design for Removable Dentures

The resin base works as the load carrier of removable dentures with design guided by oral anatomy and biomechanics. We set base coverage range depending on alveolar ridge fullness, frenum position and palatal arch depth, add relief on bone bumps and gum areas and craft smooth frenum cuts.

Well-finished sealing edges form suction to keep dentures firmly seated against oral mucosa during daily chewing and speaking. For patients with shallow palatal vault or atrophic alveolar bone, we appropriately expand peripheral coverage to improve peripheral seal and retention effect.

We adjust structure by tooth loss conditions: free-end missing teeth need larger bearing areas to spread bite force and stop denture swing caused by uneven occlusal load. Hard resin bases are sturdy with outstanding fracture resistance, flexible invisible bases look nicer and satisfy patients’ aesthetic demands; metal mesh inside big-size bases effectively avoids breakage under repeated masticatory pressure. Partial dentures with few remaining teeth usually adopt partial resin base to reduce foreign body sensation inside mouth.

Digital scan design cuts manual errors greatly by capturing accurate intraoral data instead of traditional hand-made plaster models. Properly crafted bases fit snugly, enable steady chewing, protect gums from pressure sore and slow down alveolar bone loss for durable restoration. Reasonable base thickness also helps balance occlusal stress and improve long-term wearing comfort of removable dentures.
