Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

OBJECTIVE One-piece zirconia dental implants have been widely used in Europe for many years. This in vitro study was done to evaluate the effect of abutment preparation and fatigue (cyclic) loading in a moist environment on the fracture resistance of the one-piece zirconia dental

Evaluation of a new titanium-zirconium dental implant: a biomechanical and histological comparative study in the mini pig.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND Titanium zirconium alloy with 13-17% zirconium (TiZr1317) shows significantly better mechanical attributes than pure Ti with respect to elongation and fatigue strength. This material may be suitable for thin implants and implant components exposed to high mechanical

Clinical and radiographic evaluation of narrow-diameter titanium-zirconium implants in unilateral atrophic mandibular distal extensions: a 1-year pilot study.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND The use of endosseous dental implants has led to more sophisticated fxed options when considering treatment of patients with distal extensions. The use of narrow-diameter implants may reduce the necessity for bone augmentation. The mechanical strength of titanium is limited, so titanium

Potential for adhesive wear in friction couples of UHMWPE running against oxidized zirconium, titanium nitride coatings, and cobalt-chromium alloys.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The classical wear mechanisms abrasion, fatigue, and adhesion are the most frequent causes of surface changes of ultra high molecular weight polyethylene (UHMWPE) in artificial joints. The counterpart material has a strong influence on the wear and friction behavior of artificial joints due to its

Mechanical integrity of cement- and screw-retained zirconium-lithium silicate glass-ceramic crowns to Morse taper implants.
