Fracture Resistance of Yttria‐Stabilized Zirconia Dental Implant Abutments [PDF]

open access: yesJournal of Prosthodontics, 2008
Abstract Purpose: An in vitro study was performed to assess the effect of different degrees of clinical reduction of zirconia abutments on the failure load of clinical assemblies. Materials and Methods: Zirconia abutments (Y‐TZP Ceramic Abutment, Astra Tech) were prepared with 0, 0.5, or 1 mm of external axial reduction starting 1 mm above the height ...

EXPLORING THE USE OF PULSED ERBIUM LASERS TO RETRIEVE A ZIRCONIA CROWN FROM A ZIRCONIA IMPLANT ABUTMENT [PDF]

open access: yes, 2020
Removal of zirconia crowns, commonly used as cement-retained implant fixed restorations, can be challenging. Conventional methods of crown removal are time consuming and often leave irreparable damage to the crown, which can be costly to patients and ...

Construction of unbiased dental template and parametric dental model for precision digital dentistry [PDF]

open access: yesarXiv, 2023
Dental template and parametric dental models are important tools for various applications in digital dentistry. However, constructing an unbiased dental template and accurate parametric dental models remains a challenging task due to the complex anatomical and morphological dental structures and also low volume ratio of the teeth.

Analytical and experimental position stability of the abutment in different dental implant systems with a conical implant–abutment connection [PDF]

open access: yesClinical Oral Investigations, 2012
Position stability of the abutment should be investigated in four implant systems with a conical implant-abutment connection.Previously developed formulas and an established experimental setup were used to determine the position stability of the abutment in the four implant systems with a conical implant-abutment connection and different positional ...

Biomechanical effects of original equipment manufacturer and aftermarket abutment screws in zirconia abutment on dental implant assembly [PDF]

open access: yesScientific Reports, 2020
AbstractThe use of aftermarket computer-aided design/computer-assisted manufacturing (CAD/CAM) prosthesis components in dental implants has become popular. This study aimed to (1) compare the accuracy of aftermarket CAD/CAM screws with that of original equipment manufacturer (OEM) abutment screws and (2) examine the biomechanical effects of different ...
