8 benefits of dental implants over Removable Partial Denture(RPD) and Fixed Partial Denture(FPD) Dental implants are increasingly becoming the treatment of choice for missing teeth. Their indications include replacement of single teeth, partially edentulous ridges and fully edentulous arches.
Dental implants are no longer an premium treatment modality limited to a few specialised practices. The last two decades have witnessed a massive demand for dental implants which is now pervading general dental practices.
Also, a high number of studies and controlled clinical trials report suggesting the survival rates of endosseous implants greater than 90% over 10 years regardless of the number of teeth replaced or the type of definitive prosthesis.
This means a correctly placed implant can survive for 10 years irrespective of the case.
Due to this high level of success that can be predicted, implant fixtures are potentially placed for a lifetime and also is being widely used for treatment modality.
Why it is better to have dental implant compared to Removable Partial denture(RPD) or Fixed Partial denture(FPD):
8 benefits of dental implants
- Maintenance of alveolar bone – Bone needs certain stimulation to change and maintain its form and density. After tooth extraction, there is rapid resorption of alveolar ridges which results in soft and hard tissue defects. For example, In the case of completely edentulous maxilla, bone loss occurs in a medial and superior direction, but in case of mandible the resorption is lateral and inferior. This leads to narrow maxilla and wider mandible often tending to a class III skeletal relationship. So soon after tooth loss, if implant is placed then the alveolar bone will not resorbed and the form of maxilla and mandible would not be destroyed.
- Soft tissue support – edentulism also results in reduced support for facial soft tissues, causing premature ageing;
- Improved mastication – the bite force of implant-supported prostheses is similar to the natural dentition, unlike the reduced masticatory function experienced with removable dentures;
- Improved phonetics – because implant prostheses offer better stability compared to soft tissue-borne dentures;
- Preservation of natural teeth – in partially edentulous patients, adjacent healthy teeth are spared preparation;
- Prevention of dental and soft tissue lesions – both fixed and removable prostheses are potentially harmful to teeth (decay, endodontic and periodontal problems) and the soft tissues (inflammation and continual ridge atrophy). Preventing these unwanted pathologies improves oral comfort;
- Improved aesthetics – for both teeth and facial contours due to soft tissue support from implant-supported prostheses;
- Replacing existing fixed or removable dentures – a failing FPD with decayed, endodontic or periodontally compromised abutments is potentially ideal for implant therapy. Similarly, loose, uncomfortable dentures (especially mandibular) benefit by implant-supported overdentures, which offer improved mechanical stability, mastication, speech and prevention of further bone loss.
