Implants in the Pterygoid Region: An Updated Systemic Review
Now online in the Journal of Prosthodontics, a systematic review on survival rates of modern roughened surface dental implants in the pterygoid region, co-authored by ACP member Avinash S. Bidra BDS, MS, FACP.
Historically, all dental implants were manufactured as a “turned” or a smooth machined surface, however, with improved knowledge and understanding of the osseointegration process, the importance of a roughened implant surface and surface chemistry became paramount.
The authors note that new scientific evidence over a 10 year period has exclusively described the use of modern roughened surface dental implants, and it is necessary to understand the clinical outcomes of these implants in the pterygoid region. This systematic review is an update from a review published in 2011 and covers a publication period from January 1, 2010 to December 8, 2021.
The search resulted in 10 clinical studies reporting on modern roughened surface pterygoid implants. These 10 studies reported on a total of 911 pterygoid implants with 39 reported failures over a 6-year period. The majority of failures (37) were reported during the first year time interval and a majority of them (30) occurred before loading of the pterygoid implants.
At the maximum follow-up interval of 6 years, the cumulative survival rate of pterygoid implants with roughened surfaces was 95.5%, which was 5% higher than reported in the previous systematic review which combined machined and roughed surface pterygoid implants.
This updated review provides promising data to the clinician to utilize pterygoid implants as a favorable alternative to sinus floor augmentation or zygomatic implants, both of which are more invasive, expensive, and may risk compromising sinus health.
