1. Does the implant-abutment interface interfere on marginal bone loss? A systematic review and meta-analysis
Abstract The objective of this systematic review was to compare the conical internal connection (IC) with the external hexagonal connection (EH) on the occurrence of marginal bone loss (ΔMBL). Different databases were used to carry out the selection of the elected studies. The studies were judged according to the risk of bias as “high”, “low” and �

3. Effects of different torque levels on the implant-abutment interface in a conical internal connection
Abstract The fit of the implant-abutment interface was assessed by the metallographic technique and by scanning electron microscopy (SEM), using solid abutment types at different torque levels. Forty Morse taper connections and forty solid abutments were used at different torque levels (repeated after 10 minutes) in the following groups (n = 10): 25 Ncm (gro

4. Strain analysis of different diameter Morse taper implants under overloading compressive conditions
The aim of this study was to evaluate the amount of deformation from compression caused by different diameters of Morse taper implants and the residual deformation after load removal. Thirty Morse taper implants lacking external threads were divided into 3 groups (n = 10) according to their diameter as follows: 3.5 mm, 4.0 mm and 5.0 mm. Two-piece abutments

5. Fracture resistance of abutment screws made of titanium, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone
Fractured abutment screws may be replaced; however, sometimes, the screw cannot be removed and the entire implant must be surgically removed and replaced. The aim of this study was to compare the fracture resistance of abutment retention screws made of titanium, polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK, using an external hexagonal imp

6. Bacterial microleakage at the implant-abutment interface in Morse taper implants
AIM: To evaluate the microleakage at the implant-abutment (I-A) interface of Morse tapered implants inoculated with different volumes of bacterial suspension. METHODS: Morse tapered I-A sets were selected and divided in two groups depending on the type of abutment: passing screw (PS) and solid (S), and then subdivided into four subgroups (n=6) accordin

7. In Vitro Microbiological Analysis of Bacterial Seal at the Implant-Abutment Interface Using Two Morse Taper Implant Models
O objetivo deste estudo foi avaliar comparativamente, por meio de análise microbiológica in vitro, a capacidade de selamento bacteriano de dois modelos de implante de encaixe morse. Foram utilizados 15 implantes com travamento de seus respectivos mini-pilares por fricção, sem auxílio de parafuso (Grupo 1) e 30 implantes com travamento de seus respectivo

8. Screw loosening of different UCLA-type abutments after mechanical cycling
AIM: To evaluate the loss of applied torque (detorque) values in cast and pre-machined abutments for external hex abutment/implant interface of single implant-supported prostheses subjected to mechanical cycling. METHODS: Ten metal crowns were fabricated using two types of UCLA abutments: cast and pre-machined with metal base in NiCrTi alloy and tightened to

9. Comparison of methods to evaluate implant-abutment interface
AIM: To compare two main methods of two-dimensional measurement of fit at the implant prosthodontic interface, testing the hypothesis that optical microscopy (OM) can reliably and efficiently scanning electronic microscopy (SEM). METHODS: Four frameworks with four titanium abutments joined with titanium bars were used. The implant-abutment interfaces were ex

10. Analysis by the finite element method of the stress distribution in prosthetic components placed in implants with morse cone connection in the anterior maxilla / Análise pelo método dos elementos finitos da distribuição de tensões em componentes protéticos posicionados em implantes com conexão cone morse na região anterior da maxila
The aim of this study was to evaluate through the three-dimensional method of the finite elements the stress distribution in the bone / implant interface and implant / abutment on implants with morse cone connection, placed in the anterior maxilla. From a virtual reconstruction of bone from a CT scan, cantilever prosthesis (11-21) was simulated using prosthe

11. Avaliação da microinfiltração na interface pilar-implante / Microleakage at the implant-abutment interface
A conexão entre implante e pilar está diretamente relacionada com o infiltrado bacteriano e a presença de células inflamatórias que levam à perda óssea ao redor da microfenda formada por esta interface. Entretanto, ainda não há consenso quanto aos resultados dos testes in vitro e as metodologias aplicadas para a avaliação da microinfiltração nes

12. Estudo in vitro de um material para selamento da interface implante-intermediário do tipo minipilar cônico em implantes de hexágono externo, hexágono interno e cone morse / In vitro sealing of a material of implant-abutment interface of mini conical pillar: inimplant external hexagon, internal hexagon and Morse taper
Microbial and fluidic leakage in the implant-abutment interface are shown in literature through a variety of studies, accusing the space that exists between the components of the implant, called \"GAP\", which seems to be the source of the microorganism infiltration, either from the external to the internal environment or the inverse, resulting in inflammato
