Crestal
Subjects will be included with the absence of 2-4 teeth in the posterior region of the maxilla or mandibular. Twenty patients will be recruited. Two implant placement depths, equicrestal and subcrestal, were randomly assigned to two sites of each patient with a predefined randomization tables (one crestal implant and one subcrestal implant).
