Aims and objective: Precise reproduction of the intra-oral spatial relationship implants with an impression becomes first step in achieving accurate, passively fitting prosthesis. This vitro study aims to compare dimensional accuracy dental casts obtained from open tray splinted implant techniques using two different splinting materials.
 Methods Material: A mandibular acrylic model four a...

BACKGROUND Vertical facial pattern may be related to the direction of pull of the masticatory muscles, yet its effect on occlusal force and elastic deformation of the mandible still is unclear. This study tested whether the variation in vertical facial pattern is related to the variation in maximum occlusal force (MOF) and medial mandibular flexure (MMF) in 51 fully-dentate adults. METHODS Da...

OBJECTIVE To compare, in vitro, the accuracy between dental stone casts obtained from the first and the second pour using metallic (Smart) and plastic (Triple Tray) dual-arch trays. MATERIAL AND METHODS The impressions were taken using Flexitime® vinyl polysiloxane from a typodont model with a mandibular right first molar prepared for a full crown. Ten impressions were made with each tray and...

Background and objective: Selecting a material with lower marginal gap is the key factor for successful dental prosthesis. With less of crown aggregation bacterial plaque at gingival margins, that result in periodontal diseases secondary caries could be limited. Methods: A mandibular right first molar sound tooth was prepared reference model according to preparations guideline heavy chamfer fin...
