Single Tooth Implants
The most common condition is a missing of one posterior tooth. Usually is the first molar. The best option to replace a posterior single missing tooth is a single-tooth implant. This would be the most natural method to replace a tooth. The second option would be preparing adjacent teeth and join them together with a prosthesis. For this option usually tree-unit fixed partial restoration is used. This method exhibits high rates of failure after the break-even point of 7 years. The single tooth implant exhibits the highest survival rates presented for single-tooth replacement.
Economic considerations may play in disfavor of the implant restoration at the beginning, but after several years a single tooth implant becomes more advantageous economically. Tree unit fixed bridge has to be changed after 7 years. Some teeth health related problems can be presented. Due to the difficulty of hygiene, the pillars of the bridge can present decay. That can become a major problem if the decay is extensive. Even can end up with the necessity of implant placement due to impossibility of restoration. As a result the future savings will offset the initial higher cost of single tooth implant, especially because the adjacent teeth are more likely to survive longer and replacement of a restoration is unnecessary.
