AIM To investigate the importance of attachment types on the retention loss of extracoronal attachment-retained removable partial dentures depending on the usage period. MATERIALS AND METHODS In order to observe the retention loss of 5 different attachments (OT Strategy, OT Strategy-metal protected, Vario-stud-snap and Vario-soft 3 and ERA-RV) over time, attachment-retained partial dentures r...

Various options have been introduced for the selection of implant overdenture attachments. Attachment wear due to the repeated insertion and removal of dentures has caused problems such as decreased retention and the requirement for suprastructure remanufacturing. In these cases, a Locator bar system was applied using the drill and tapping technique to achieve total retrievability. In a 55-year...

UNLABELLED The aim of this study was to assess complete edentulous patient satisfactionwith two treatment alternatives--conventional dentures and mini implant anchored overdentures. MATERIALS AND METHODS Study sample comprised 36 patients--18 treated with newly made conventional prosthesis and 18 with mini implants anchored overdentures, with a ball attachment system (from IMTEC Corporation)....

BACKGROUND This study was conducted to compare and evaluate the effect of two different attachments (locator attachment and ball and socket [B&S] attachment) on implants and natural abutments supporting structures, in cases of limited inter-arch spaces in mandibular Kennedy Class I implant supported removable partial over dentures by measuring the bone height changes through the cone beam radio...

OBJECTIVE The main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region. MATERIALS AND METHODS Four three-dimensional finite element models (3D FEM) were designed from a mandible containing an implant-supported bridge extending between canines, an...

Aim: This study was conducted to evaluate the effect ball and equator attachments strain (invitro study) of mandibular over denture retained by single midline implant for completely edentulous patient. Subjects methods: Ten complete lower dentures have attachment another ten were constructed on acrylic models covered rubber material simulate oral mucosa implant, evaluated around in posterior ar...

PURPOSE Many different attachment systems (eg, bars, studs, magnets, telescopic copings) have been used to retain overdentures. The current study aimed to investigate the load transfer characteristics and to compare the stress levels of four attachment designs for mandibular overdentures retained by one central implant and two inclined distal implants. MATERIALS AND METHODS Photoelastic mandi...
