The disadvantages of Dental implants are :
- Dental implants require a greater financial investment than other alternatives. Also they take several visits over a period of several months to complete. In some cases, the time frame for treatment can be considerably shortened with the final teeth delivered in only a few weeks or days.
- As in any surgical procedure, dental implants involve a small risk of infection.
- Successful integration of dental implants cannot be guaranteed but most studies show 95% or more success rate.
- Mechanical fracture of fixtures, bridges, abutment screws or loosening of screws can occur. These problems have been reported in less than 5% of the patients. Porcelain fracture of crown and bridgework on implants is much more prevalent than on natural teeth due to the fact that implants have no mobility.
