Abstract

Aim:

To study the biological outcomes of angled abutments when used to restore single or partial fixed implant supported prosthesis.

Methodology:

An online search using Medline (Ovid) and PubMed databases was conducted using terms and combinations such as; angled abutment, bucco-lingual angulation, biological complication, marginal bone loss and implant supported fixed partial prosthesis. The focus of the study was to evaluate the effect of bucco-lingual/palatal angulation with implant supported single or partial FPD, which was conducted through specific inclusion and exclusion criteria.

Results:

The search revealed a total of 8 human in vivo and 10 in vitro studies. Of that, three in vivo studies were excluded and two from in vitro studies.

Conclusion:

According to the available studies, no significant bone loss was associated with single and partial implant supported prostheses when angled abutments are used to correct the tilted buccolingual implants. The results should be evaluated carefully due to the short follow up duration of the clinical studies; further long term follow up studies are needed. In cases where implants were misplaced, the best is to use platform switched implants with a smooth neck, maintain at least a minimum of 2 mm or more of buccal bone and utilize the lowest angulation values as possible.

Keywords: biological outcom, Angled abutment, Dental implant, Supported crown, Implant supported FPD, Buccolingual angulation.
