Abstract

BACKGROUND:

It is important to understand the influence of different collar designs on peri-implant marginal bone loss, especially in the critical area.

OBJECTIVES:

The purpose of the present systematic review and meta-analysis was to compare dental implants with different collar surfaces, evaluating marginal bone loss and survival rates of implants.

METHODS:

Eligibility criteria included clinical human studies, randomized controlled trials, and prospective and retrospective studies, which evaluated dental implants with different collar surface in the same study.

RESULTS:

Twelve articles were included, with a total of 492 machined, 319 rough-surfaced, and 352 rough-surfaced microthreaded neck implants. There was less marginal bone loss at implants with rough-surfaced and rough-surfaced microthreaded neck than at machined-neck implants (difference in means: 0.321, 95% CI: 0.149 to 0.493; p < 0.01).

CONCLUSION:

Rough and rough-surfaced microthreaded implants are considered a predictable treatment for preserving early marginal bone loss.
