Many patients with missing teeth are confused about denture types and have difficulty making choices. Three main restoration options are available. Treatment plans should be selected according to oral condition, general health, budget and oral‑care compliance to achieve satisfactory outcomes.
1. Fixed dental prosthesis
Used to restore one or multiple missing teeth in dentition. It is bonded onto prepared natural abutment teeth or implants with luting agent. Patients cannot remove it by themselves.
Conventional fixed bridge requires grinding healthy adjacent teeth as abutments. Implant‑supported fixed crowns are alternative solutions without preparing natural teeth.
Advantages: stable, high chewing efficiency and minimal foreign‑body sensation. Disadvantages: traditional fixed bridge sacrifices healthy tooth tissue of neighbouring teeth.
2. Removable dentures
Supported by remaining natural teeth and oral mucosa, retained via clasps and base plates. Patients can take them out for cleaning. Applicable for single‑tooth loss, multiple‑tooth loss and complete edentulism.
Advantages: minimal tooth preparation and cost‑effective. Disadvantages: noticeable foreign‑body sensation, relatively low chewing efficiency. Daily removal‑and‑cleaning and regular replacement are required.
3. Dental implant restoration
Artificial root fixtures are surgically placed into alveolar bone to support the suprastructure crown.
Indicated for patients with acceptable general health and sufficient alveolar bone. Bone augmentation or pre‑treatment is required for cases with inadequate bone volume, uncontrolled systemic disease or untreated periodontitis.
Advantages: no grinding of adjacent natural teeth. Comfort, aesthetics and masticatory performance are close to natural teeth.
Advantages of implant‑based tooth restoration
1. Implants deliver masticatory performance similar to natural teeth and are known as "the third set of teeth". With proper oral maintenance, implants can serve for a long time, though not absolutely permanent. Regular follow‑up check‑ups are mandatory.
2. Unlike fixed bridges which grind adjacent healthy teeth, implants spare natural teeth. Note: Poor oral hygiene may trigger peri‑implant inflammation, leading to gingival recession and bone loss. Daily cleaning and periodic reviews are essential.
3. One implant for one missing tooth. No damage is inflicted on other natural teeth.
