No results posted yet for this study

Summary

A study designed as a randomized controlled trial of parallel group design will be conducted at the Dental clinic of the University of Valencia to evaluate the influence of 2.5 mm high abutments with different shapes (commercially available high abutments vs high abutments with modified shape to imitate short abutments) on peri-implant bone loss around bone level implants with platform switching in partially edentulous patients that require a fixed rehabilitation supported by two implants in the posterior mandible or maxilla and in fixed rehabilitation supported by one implant in the anterior mandible or maxilla.

Conditions

  • Dental Implant
  • Bone Resorption

Interventions

PROCEDURE

Commercially available high abutments placement

Patients will be randomly selected for the commercially available high abutments option. Two or three implants will be placed following the drilling protocol suggested by the manufacturer. Implants will be placed 0.5mm subcrestal. Once the implants have been placed, periapical radiographs and clinical pictures will be taken. Implants will be uncovered 10 weeks after being placed. After performing the incision and elevation a minimal flap, conventional high transmucosal abutments will be screwed using the torque recommended by the manufacturer. Once the abutments have been screwed, periapical radiographs and clinical pictures will be taken. The abutments will not be unscrewed thereafter throughout the study.

PROCEDURE

Modified shape abutments

Patients will be randomly selected for the modified shape abutments option. Two or three implants will be placed following the drilling protocol suggested by the manufacturer. Implants will be placed 0.5mm subcrestal. Once the implants have been placed, periapical radiographs and clinical pictures will be taken. Implants will be uncovered 10 weeks after being placed. After performing the incision and elevation a minimal flap, modified high transmucosal abutments will be screwed using the torque recommended by the manufacturer. Once the abutments have been screwed, periapical radiographs and clinical pictures will be taken. The abutments will not be unscrewed thereafter throughout the study.
