Implants are tiny titanium screws or posts that are surgically placed in the bone. Once integrated into bone they act like roots onto which small posts are attached which protrude through the gums. These posts provide stable anchors to the replacement teeth.
Implants maintain the bone height by stimulation and prevents unnecessary trimming of adjoining teeth for bridge placement. Since implants are titanium posts there is no chance for decay on implants. Implants can service you for several years with regular professional cleaning and proper home care.
The teeth that support the partial denture are weakened due to the excessive loads acting on them and eventually are lost. The denture rests on the gum causing tissue abrasion and bone loss. Removable dentures may slip or cause embarrassing clicking sounds while eating or speaking.
Studies show that within five to seven years there is a failure rate of up to 30% in teeth located next to a fixed bridge or removable partial denture.
Many people who are missing a single tooth opt for a fixed bridge; but a bridge may require the cutting down of healthy, adjacent teeth that may or may not need to be restored in the future. Then there is the additional cost of possibly having to replace the bridge once, twice or more over the course of a lifetime due to decay or gum problems affecting the anchor teeth.
Another option to replace missing teeth is a removable partial denture or complete denture depending on the number of teeth missing. The chewing efficiency with a denture is reduced to more than half of that of natural teeth.
