Summary
The objective of this randomized controlled trial is to evaluate changes in marginal bone levels and soft tissue dimensions around implants placed with the IAI at different positions in relation to the alveolar crest
Detailed description
The objective of this randomized controlled trial is to evaluate changes in marginal bone levels and soft tissue dimensions around implants placed with the IAI at different positions in relation to the alveolar crest. 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). Patients will be recalled for oral hygiene maintenance and prosthetic controls at 1year, 3 years, 5 years after final restoration.
