Dental Pins
Abstract
Our radiological positioning device has a total length of 3.5 mm and has a ball on its end, thus resembling conventional pins in principle. Due to its conical form, the device can be easily placed in the mucosa at the designated insertion site. The X-ray pin is reliably stable in position, guarantee...

Abstract
This article reports the findings from a study conducted to answer this research question: can adhesive resin liners provide retention that is the same as dentinal pins or pots and slots when restoring complex amalgam restorations? The study methodology consisted of two components: a review of the l...

Abstract
Many endodontically-treated teeth require quick, simple, low-cost restorations. This study evaluated the effect of horizontal pins and flowable composites on the fracture resistance of endodontically-treated maxillary premolars directly restored with resin composite. In this in vitro study, 64 intac...

General dentistry (55)2 2007
Abstract
Excellence in clinical restorative dentistry may be defined in many ways. Occlusion, esthetics, and morphology are important but none of these factors is more important than longevity. Not all of us will enjoy the clinical success that Dr. Tucker did but the time-tested technique of venting is one w...

Abstract
A pin and bar-retained composite bridge can be used to replace missing teeth in cases when minimal tooth reduction is desired and patients refuse implant surgery for psychological reasons. This case report describes the clinical procedure for a pin and bar-retained composite bridge as a conservative...

Abstract
A common dental problem is restoring teeth with gingival or subgingival margins and extensive loss of coronal tooth structure. A technique is presented for doing so by making a wax foundation on the tooth and injecting vinyl polysiloxane impression material around the foundation to form a matrix for...

A restorative technique for replacing congenitally missing lateral incisors was necessary when implants were not an option. Two three-unit bridges were considered but were rejected in favor of the much more conservative pinledge retainers. Only a relatively small amount of tooth structure was remove...

Abstract
Mean failure load for nonsoldered crowns was 349 +/- 63 kgf in phase I and 228 +/- 49 kgf in phase II. Soldered crowns showed a significantly lower failure load (265 +/- 82 kgf [phase I; P<.02] and 154 +/- 108 kgf [phase II; P<.04]) and a greater standard deviation. CONCLUSION: Soldered metal-porcel...
