Does implant placement using a minimally invasive technique increase early failures among trainees at an academic center?

Purpose: This study aims to identify whether dental implants placed using a flapless technique have a higher early failure rate, defined as failure within 6 months of placement, compared to implants placed with flap elevation when a surgical guide is not used.

Methods: A retrospective cohort study was conducted to evaluate implants placed with either flapless (FL) or mucoperiosteal flap (MF) surgery between 2006 and 2012 at the Philadelphia VA Medical Center (PVAMC). Implant status after FL or MF surgery was assessed using dental encounter and radiographs at subsequent follow-up appointments to assess for early implant failures within 6 months of implant placement.

Low Insertional Torque and Early Dental Implant Failure.

Purpose: There is lack of uniformity regarding the ideal insertional torque with which dental implants need to be placed. The purpose of this retrospective analysis is to compare the incidence of early dental implant failures with an insertional torque less than 30 N-cm to implants placed with an insertional torque 30 N-cm or greater.

Methods: A retrospective cohort study was conducted to evaluate dental implants placed between 2015 and 2016 at the Veterans Affairs North Texas Health Care System in Dallas.

Effect of dose and release rate of CTGF and TGFβ3 on avascular meniscus healing.

Meniscus tears in the avascular region rarely functionally heal due to poor intrinsic healing capacity, frequently resulting in tear propagation, followed by meniscus deterioration. Recently, we have reported that time-controlled application of connective tissue growth factor (CTGF) and transforming tissue growth factor β3 (TGFβ3) significantly improved healing of avascular meniscus tears by inducing recruitment and step-wise fibrocartilaginous differentiation of mesenchymal stem/progenitor cells (MSCs). In this study, we investigated effects of the dose of CTGF and the release rate of TGFβ3 on avascular meniscus healing in our existing explant model.

Engineered Healing of Avascular Meniscus Tears by Stem Cell Recruitment.

Meniscus injuries are extremely common with approximately one million patients undergoing surgical treatment annually in the U.S. alone.
