About

The aim of the study is to compare longitudinally the clinical performance of dental implants with different surfaces placed in single tooth gaps at the posterior maxilla and mandible of adults. It is a randomized clinical trial, in which participants will be randomly allocated to two groups: test group (implants with hydrophilic surface) and control group (implants with hydrophobic surface). The null hypothesis is that the implant stability quotient of hydrophilic and hydrophobic dental implants show a similar progression after placement in posterior tooth gaps.
