BACKGROUND Short, rough-surfaced palatal implants are an established and reliable anchor for orthodontic treatment. Until recently, removal was only possible surgically using a hollow cylinder trephine. This standard method retrieves the implant combined with a larger bone volume and is therefore considered invasive and has known complications. Lately, an explantation tool which allows a suffic...

We have reviewed our experience of the removal of deep extremity orthopaedic implants in children to establish the nature, rate and risk of complications associated with this procedure. A retrospective review was performed of 801 children who had 1223 implants inserted and subsequently removed over a period of 17 years. Bivariate analysis of possible predictors including clinical factors, compl...

Radiographic osteopenia is regularly observed after implant removal from a fracture or femoral osteotomy but has not been objectively quantified. Hardware removal is generally performed months to years after the index event (fracture or osteotomy) when full activity has been resumed. Objectively demonstrable bone mineral deficiency affects fracture risk. Hardware removal may facilitate the retu...

STATEMENT OF PROBLEM A number of studies about the nano-treated surfaces of implants have been conducting along with micro-treated surfaces of implants. PURPOSE The purpose of this study was to get information for the clinical use of nano-treated surfaces compared with micro-treated surfaces by measuring removal torque and analyzing histological characteristics after the placement of various ...

The major drawback of cement-retained restorations is the extrusion of the excess cement into the peri-implant sulcus, with subsequent complications. Insufficient removal of the excess cement may initiate a local inflammatory process, which may lead to implant failure. This article presents a method of controlling cement flow on implant abutments, minimizing the excess cement around implant-ret...

A very low incidence of complications of rehabilitating jaw with implant therapy ismigration of dental implants into maxillary sinus. Implant migration into the maxillary sinus may be followed by sign of infection and oroantral communication. This way, paranasal sinus function will be appearing altered after the implant migration and hence implant removal is utmost important.

The aim of this study was to test whether bone could be formed in peri-implant defects at immediate transmucosal implants using guided bone regeneration. Ten patients (median age 48 years) underwent comprehensive dental care including the placement of an implant into an extraction socket immediately following removal of a tooth. An expanded polytetrafluoroethylene membrane and the mucoperiostea...

A total of 48 repeat breeder cows were equally divided in to two treatment groups as NOR and NOR-PG and were treated with norgestomet ear implants on day 10 following natural oestrus and a control group. At the time of ear implant insertion, 2 ml of SMB injection was administered intramuscularly to all the cows. The implant was removed after 9 days. Cows in NOR-PG group were injected with 0.98 ...

INTRODUCTION AND OBJECTIVES The cochlear implant is a surgical procedure that has increased substantially, because the paediatric population is diagnosed and implanted early and because there are increased potential indications. This device has the inherent risk of failure in performance, as dies any active medical device, which is the most common cause of implant removal. Our goal was to under...
