Abstract Objective: The objective of this study was to explore effects implant macrodesign and diameter on initial intraosseous stability interface mechanical properties immediately placed implants. Material method: Mandibular premolars four fresh‐frozen human cadavers were extracted. Ø 4.1/4.8 mm ITI® TE®, 4.1 4.8 solid screw synOcta® implants into freshly prepared extraction sockets. Resonance frequency analysis conducted quantify primary quotient (ISQ). Installation torque value (ITV)...

The aim of this randomized controlled clinical trial was to compare the early outcome slip-cast glass-infiltrated Alumina/Zirconia and CAD/CAM Zirconia all-ceramic crowns. A total 30 InCeram® Cercon® crowns were fabricated cemented with a glass ionomer cement in 20 patients. At baseline, 6-month, 1-year, 2-year recall appointments, Californian Dental Association (CDA) quality evaluation system used evaluate prosthetic replacements, plaque gingival index scores explore periodontal treatments....

Abstract Purpose: The objective of this biomechanical study was to explore the effect bone micro‐morphology on initial intraosseous stability implants with different designs. Material and methods: Straumann Astra Tech dental were placed into anterior posterior regions completely edentulous maxilla mandible a human cadaver. Experiments undertaken quantify implant micro‐morphology. Installation torque values (ITVs) quotients (ISQs) measured determine stability. For quantification relative...

Although the destructive effect of cantilevered implant supported fixed partial prosthesis is well known, in some cases usage cantilever extension seems to be inevitable for many clinicians. The purpose this study was evaluate additional placement a shorter place on stress distribution compared with mandibular posterior edentulism. A Kennedy II finite element model constructed. Six different were designed according two main configurations; anterior and extensions configurations. An oblique...

Abstract Purpose To evaluate the effect of different silica‐based ceramic materials on mechanical failure behavior endocrowns used in restoration endodontically treated mandibular molar teeth. Materials and Methods Thirty‐six intact teeth extracted because a loss periodontal support received root canal treatment. The were prepared with central cavity to endocrowns, replacing occlusal surface mesial‐lingual‐distal walls. Data acquisition tooth surfaces was carried out digitally powder‐free...

To compare dynamic fatigue resistance of one- and two-piece abutments connected to internally notched morse-taper oral implants.Sixteen synOcta ITI implants were tightened into two metal models. SynOcta for cement-retained restorations solid divided equal groups torque-tightened the implants. Each implant received a crown. Cyclic axial lateral peak loads 75+/-5 N applied on duty 500,000 cycles at 0.5 Hz, an angle 20 degrees. Prior experiments each 100,000 loading, periotest values (PTVs)...

Abstract: The purpose of this study was to evaluate the mechanical characteristics implant–abutment connection a reduced‐diameter ITI ® dental implant. A finite element model ∅ 3.3 mm×10 mm solid‐screw implant and 6° solid abutment 4 in height constructed, complex embedded vertically center 1.5 cm×1.5 cm acrylic cylinder. Static vertical oblique loads 300 N were applied separate load cases. contact area defined between nonlinear stress analysis performed. magnitude distribution Von Mises...

ABSTRACT Purpose To assess the effect of scanbody (SB)‐type, edentulous site, and restoration‐type on scan quality SBs used in treatment short‐span edentulism. Materials Methods The cohort consisted with different specifications connected to bone‐level implants for intraoral digitalization fabrication fixed restorations. matched library CAD files digital implant position transfer into dental software were enrolled study group. Intraoral records categorically evaluated SB scans. In...

To compare the primary stability of implants placed in conventional and osteotome sites to evaluate level correlation between cutting torque measurements, resonance frequency analysis (RFA), bone density.Eight human femoral heads were scanned with computed tomography for density measurements as Hounsfield units (HU), individualized tomography-based surgical stents prepared placement implants. Five implant sockets each collum (CoF), caput (CaF), trochanter (Tr-MM) section using drilling...
