T HE CONCEPT PREVAILS IN dental teaching that the occluding surfaces of the posterior teeth should retain the same form throughout their lifetime that they had at the time of eruption. While it is considered normal for the mamelons to wear off of the anterior teeth, the cusps of the posterior teeth are expected to remain as they were when they erupted. This concept of intact and well-defined cu...

AIM Relating the marginal fit of the castings, to the accuracy of the impression produced using laminated hydrocolloid impression technique, alginate and double-mixed polyvinyl siloxane. Basic objective of the study is to check the feasibility of the use of laminated hydrocolloid impression technique in the fixed partial denture. MATERIALS AND METHODS The precisely machined metal die was desi...

The ideal restoration of endodontically treated teeth (ETT) has been widely and controversially discussed in the literature. Prevention of healthy dental structure is essential to help mechanical stabilization of tooth-restoration integrity, increase the amount of suitable surfaces for adhesion and thus positively affect the long-term success. ETT are affected by a higher risk of biomechanical ...

“Clinical Showcase” is a series of pictorial essays that focus on the technical art of clinical dentistry. The section features step-by-step case demonstrations of clinical problems encountered in dental practice. If you would like to contribute to this section, contact editorin-chief Dr. John O’Keefe at [email protected]. Anterior crossbite is an occlusal problem with functional and esthetic ...

OBJECTIVES The objective of this systematic review was to assess the survival of cantilever fixed partial dentures (FPDs) and the incidence of biological and technical complications. METHODS An electronic MEDLINE search supplemented by manual searching was conducted to identify prospective and retrospective cohort studies on FPDs with a mean follow-up time of at least 5 years. Patients had to...

A growing number of clinical studies show that early (2 months) and immediate loading protocols may be predictable. However, they are based on clinical stability only The aim of this case report was to document the osseointegration status of two Osseotite implants after 2 months of healing in soft bone corresponding to type IV and subjected to two distinct mechanical environments. A completely ...

The most promising solution to missing teeth in today’s world seems to be Implants. Conventional fixed partial dentures and resin bonded bridges are the most commonly used alternatives. However, it is not always possible to use these solutions, especially in case of missing anteriors with excessive space. A simple yet often overlooked solution to replacing missing teeth and maintaining the dias...

A person constrained to walk at a given speed v on a treadmill, chooses a particular step frequency f and step length d=v/f. Testing over a range of speeds generates a speed-frequency (v-f) relationship. This relationship is commonly posited as a basic feature of human gait. It is often further posited that this curve follows from minimum energy cost strategy. We observed that individuals walki...
