Immediate loading of implants replacing single molars are of high interest as first and second molars are the most commonly missing teeth in posterior jaw. Wide platform (WP) implants offer greater surface area for Osseo integration and are more capable of handling higher occlusive forces in the posterior regions of jaw compared to regular diameter implants. Few studies have evaluated 6 mm wide diameter implants for posterior single tooth restorations.
The present study aimed at evaluating clinical and radiological outcomes of wide diameter (6 mm) implants used for cement-retained prosthetic restorations of single molars in immediate function.
At the end of 1 year, cumulative survival rate was 98.1% (table 1), and there were no mechanical or biological complications (table 2). The mean marginal bone remodeling was -0.17 ± 1.84 mm. Marginal bone level changes with distribution frequencies for all sites are presented in table 3.
This prospective study demonstrates a good predictability for wide diameter (6 mm) implants when used to replace of single molars. Its use is associated with good outcomes in terms of implant survival, marginal bone changes and soft tissue health at the end of one year. It also confirms effectiveness of use of immediate loading protocol in terms of good 1-year implant stability. A longer follow up study is necessary to evaluate the long term success of this technique.
