This study evaluate the use of bovine teeth as a substitute for human teeth on fracture strength tests of composite fixed partial dentures (Cpd), with and without fiberglass reinforcement (Fg). Eighty teeth were selected, being 40 bovine incisors, 20 human premolars and 20 molars. Bovine incisors were ground to get a platform, simulating an occlusal surface of human molar. Teeth in pairs were e...

Clinical evidence has shown that dental bridge (DB) misfit is more frequent than individual crown restoration misfit, and that it causes restorative failures. A comparative study of misfit profiles was performed for the most common clinical situations in mouth rehabilitation procedures with fixed restorations: gold-cast DB and porcelain metal alloy DB. Evidence from this study may lead dentists...

Purpose: The phenomenon of developing a certain tactile sensibility through osseointegrated dental implants is called osseoperception. Active tactile sensibility can be tested by having the subject bite on test bodies. The aim of the study was to assess the active tactile sensibility of osseointegrated single tooth dental implants according to psychophysical method of constant stimuli. Material...

In a historical pendulum of porcelain veneer preparation concepts, an oversimplified version of the so-called "no prep" approaches has resurfaced. A case from the USC student clinics is presented, which could be easily considered by many as a "no prep" veneer case. Moderate tooth preparations guided by natural morphology were used instead with a great benefit on the final outcome. While it is w...

The aim of this study was to analyse the stress distribution in maxillary canines restored with different post systems and definitive crowns. The models of restored teeth with glass fiber, quartz fiber, titanium posts and crowns were developed with the Finite Element Method (FEM) in order to analyse their stress distribution when subjected to external compressive loads. Von Mises stress distrib...

Whole-organ regeneration has great potential for the replacement of dysfunctional organs through the reconstruction of a fully functional bioengineered organ using three-dimensional cell manipulation in vitro. Recently, many basic studies of whole-tooth replacement using three-dimensional cell manipulation have been conducted in a mouse model. Further evidence of the practical application to hu...

Fracture of anterior teeth due to trauma is the most frequent type of injury affecting permanent dentition. Despite the availability of a wide range of restorative materials, none could match the properties of natural tooth structure like translucency, wear resistance, and color stability. Hence fragment re-attachment is an excellent method of restoring fractured teeth. When the fractured fragm...

An integrated experimental and theoretical approach is proposed for the evaluation of stress within a natural tooth during bruxing. A physical model was developed that used strain gauges bonded to the buccal and lingual heights of contour of extracted, intact maxillary premolar teeth for the validation of a two-dimensional finite element model of a natural, intact maxillary premolar tooth. Resu...

The clinician can successfully graft dental extraction sites to improve the aesthetics and function of the final restoration. When an extraction site receives a graft, ridge preservation is enhanced, pontic form can improve, dental implants can be placed in the correct position, and the prosthetic outcome will be enhanced.
