Background: The accuracy of digital implant transfer is currently under investigation in relation to the effect of saliva, scan body material, and exposed length.
Methods: Six completely edentulous casts with four implant fixtures were fabricated. The four implant fixtures in each cast were placed below the crest of the ridge of the casts by 1.
Background: Placing implants deep sub-gingivally may affect the accuracy of implant impression techniques and the fit of final restoration.
Purpose: The aim of this in-vitro study was to evaluate the effect of soft tissue thickness on accuracy of conventional and digital implant impression techniques.
Methods: Four parallel implant analogues (A, B, C, D) placed in each of two epoxy resin models representing edentulous mandible covered by flexible polyurethane material with two different thickness two mm and four mm.
Aims: The purpose of this in-vitro study was to evaluate the screw loosening of two different forms of implant abutment connection designs, and two implant diameters by measuring removal torque value (RTV) before and after cyclic loading.
Materials And Methods: Twenty implant fixtures were divided equally into 2 groups (N=10): group I fixture with conical hybrid connection (CH), and group II fixture with internal hex connection (IH). Each group was divided equally into two subgroups according to implant diameters: subgroup A (3.
Background: The purpose of this in vitro study was to evaluate the effect of different angulations and collar lengths of the implant abutment on screw loosening by measuring removal torque value (RTV) before and after dynamic cyclic loading using digital torque gauge.
Methods: A total 90 sets of 4.5 mm diameter × 10 mm length bone level implants with conical hybrid connection were used.
