The osseointegration of Mitek mini anchors in the mandibular condyle
1Oral and Maxillofacial Surgery, Baylor College of Dentistry-Texas A&M University System, Baylor University Medical Center, Dallas, TX, USA.
Purpose:
This study examined the histomorphology of the bone around the Mitek mini anchors (Mitek Inc, Norwood, MA) after 3 to 59 months of implantation.
Materials And Methods:
Thirteen condylar specimens from 8 patients were evaluated. Each of these patients had had previously placed Mitek mini anchors and braided polyester sutures for temporomandibular joint (TMJ) articular disc stabilization. Histologic evaluation of each specimen was performed to determine the degree of osseointegration. Each specimen was also evaluated for anchor configuration, fracture, and particulation and the presence or absence of intervening fibrous connective tissue or an inflammatory cell infiltrate.
Results:
All anchors became osseointegrated without evidence of associated inflammation or fibrous connective tissue formation along the surface. There was no evidence of anchor fracture or particulation.
Conclusions:
The Mitek mini anchor can osseointegrate in the mandibular condyle. These suture anchors remain intact and biocompatible for as long as 59 months, the longest interval examined in this study.
