Generally, endosseous implants can be placed according to a nonsubmerged or a submerged technique and in 1-piece or 2-piece configurations. Recently, it has been shown that peri-implant crestal bone reactions differ significantly radiographically as well as histometrically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of a micro...

The aim of this study was to evaluate the effect of water irrigation on heat dissipation kinetics following abutment preparation of 1-piece dental implants. UNO 1-piece dental implants were mounted on Plexiglas apparatus clamping the implant at the collar. T-type thermocouple was attached to the first thread of the implant and recorded thermal changes at 100 millisecond intervals. Implants were...

The objective of the study was to evaluate the degree of temperature change in the bone, directly adjacent to the implant site during the abutment part of one-piece implants, during procedures involving different cutting techniques. Three different one-piece implants: Osteoplant, Nobel Direct, Q-implant were cut with air-turbine burs after insertion in fresh pig ribs. Tests were performed with ...

STATEMENT OF PROBLEM The transition from implant to abutment is solid in 1-piece (1P) and broken in 2-piece (2P) implant designs. This difference may affect occlusal load distribution and marginal bone response. PURPOSE To determine whether 1P and 2P implants with equivalent geometries exhibited stresses and strains differently under applied loading conditions. MATERIALS AND METHODS Design ...

STATEMENT OF PROBLEM It is unknown if the consumption of hot beverages after implant placement poses a danger of overheating at the bone-implant interface. PURPOSE The purpose of this study was to investigate the effect of simulated consumption of hot beverages on the heat transfer to different dental implant types, implant sizes, and the presence of an interim restoration. MATERIAL AND MET...

OBJECTIVES Microbial leakage through the implant-abutment (I-A) interface results in bacterial colonization in two-piece implants. The aim of this study was to compare microleakage rates in three types of Replace abutments namely Snappy, GoldAdapt, and customized ceramic using radiotracing. MATERIALS AND METHODS Three groups, one for each abutment type, of five implants and one positive and o...

BACKGROUND Today, implants are placed using both non-submerged and submerged approaches, and in 1- and 2-piece configurations. Previous work has demonstrated that peri-implant crestal bone reactions differ radiographically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of the interface (microgap) between the implant and abutment/...

PURPOSE Immediate loading and/or restoration of dental implants requires the assessment of implant stability, which is best performed by resonance frequency analysis (RFA) prior to loading. One-piece dental implants are usually used for immediate loading, but there is currently no available reliable method to assess the primary stability of one-piece dental implants. Therefore, this study sough...

Purpose. Loosening and fracture of abutment screws are one the most common complications in implant-retained fixed prostheses. Thus, applying proper tightening torque to screw is important for preventing loosening effect ensuring stability implant fixture-abutment connection. Therefore, this study, we aimed investigate on connection a two-piece zirconia system using finite element analysis (FEA...
