The ‘baseball’ orbital implant: A prospective study

Implant-supported overdentures: a longitudinal prospective study.

The aim of this study was to evaluate the clinical function and long-term prognosis of overdentures retained by a small number of implants in the maxilla and mandible using one of two different attachment systems. Included in the study were all patients referred to specialty clinics in Jönköping and Linköping, Sweden, during the treatment period who needed an overdenture and could be provided w...

Predicting Orbital Fractures from Baseball Impact

Zygoma fracture as a result of baseball impact presents a particular concern due to its prevalence and importance as a structure of the orbit. The purpose of this study was to develop risk functions for zygoma fracture based on ball type and velocity. A normal distribution was assumed for previous data on the fracture strength of the zygoma. The fracture strength data was mapped with the force ...

Magnetic orbital implant.

THIs implant was developed with the object ofincreasing the degree ofmovement obtained with the Allen type ofburied orbital implant. The satisfactory way in which these implants are retained in the orbit is demonstrated by the large number which have now more than fulfilled the 2-year follow-up period suggested by Choyce (1952). The retention of the magnetic form of implant appears to be as goo...

A Case of Orbital Abscess following Porous Orbital Implant Infection

PURPOSE We present a case of orbital abscess following porous orbital implant infection in a 73-year-old woman with rheumatoid arthritis. METHODS Just one month after a seemingly uncomplicated enucleation and porous polyethylene (Medpor) orbital implant surgery, implant exposure developed with profuse pus discharge. The patient was unresponsive to implant removal and MRI confirmed the presenc...
