Impact of abutment geometry on early implant marginal bone loss. A double-blind, randomized, 6-month clinical trial.

ABSTRACT:

Objectives

The objective of this study was to analyze the impact of the abutment width on early marginal bone loss (MBL).

Material and methods

A balanced, randomized, double-blind clinical trial with two parallel experimental arms was conducted without a control group. The arms were "cylindrical" abutment and "concave" abutment. Eighty hexagonal internal connection implants, each with a diameter of 4 × 10 mm, were placed in healed mature bone. The main variable was the peri-implant tissue stability, which was measured as MBL at 8 weeks and 6 months.

Results

The final sample consisted of 77 implants that were placed in 25 patients. 38 (49.4%) were placed using the cylindrical abutment, and the other 39 (50.6%) were placed using the concave abutment. The early global MB
