Comparison of Extra-short (4 mm) Implants Used as Distal Support of a Maxillary Full-arch Fixed Dental Prosthesis vs. 10 mm Implants Installed After Sinus Floor Elevation.

Alveolar Bone Loss Clinical Trial

Official title:
Comparison of Extra-short (4 mm) Implants Used as Distal Support of a Maxillary Full-arch Fixed Dental Prosthesis vs. 10 mm Implants Installed After Sinus Floor Elevation. A Randomized Clinical Trial

Clinical Trial Summary

Recently, 4 mm long implants with a standard diameter have been used for the restoration of the posterior edentulous mandible with favorable results. However, randomized clinical trials reporting the results from full-arch fixed dental prosthesis that included 4 mm long implants placed in the posterior regions of the maxilla have not been published yet. The aim of the present study will be to compare the survival and success rates of 4 mm implants used as distal support of a maxillary full-arch fixed dental prosthesis with standard (10 mm) implants placed in association with a bilateral sinus floor augmentation procedure

Clinical Trial Description

Two groups will be randomly prepared, the Short group and the Standard group. In the Short group, one 4 mm long and 4.1 mm in diameter implant (extra-short implant) will be installed in each side of the posterior region of the maxilla. In the Standard group, bilateral sinus floor elevations will be performed. After 4 months of healing, one 10 mm long and 4.1 mm in diameter implant (standard implant) will be installed into each augmented sinus. In the frontal region, four 10 mm long implants will be installed in both groups. Clinical assessments and x-rays will be taken at prosthesis delivering (6-8 weeks after implant installation), and after 6, 12, 18 and 24 months. ;
