During treatment planning it is important to recognize different gingival biotypes and forms, because they can affect the esthetic outcome of the treatment. This review provides an insight into the different gingival biotypes, their response to inflammation and trauma; significance in different prosthodontic modalities like esthetic rehabilitation and implant therapy.

A case of a collarless metal ceramic fixed partial denture with preparations made at a slightly supragingival level is reported. The absence of the metal collar in the buccal portion of the abutments provides an excellent esthetic appearance. The use of a collarless metal ceramic fixed partial denture is a viable approach for restoring dentition where the esthetic quality is the primary concern.

The placement of dental implants in the anterior maxilla is a challenge for clinicians because of patients' exacting esthetic demands and difficult pre-existing anatomy. This article presents anatomic and surgical considerations for these demanding indications for implant therapy. First, potential causes of esthetic implant failures are reviewed, discussing anatomic factors such as horizontal o...

Taping is often used to manage the high rate of knee injuries in ballet dancers; however, little is known about the effect of taping on lower-limb biomechanics during ballet landings in the turnout position. This study investigated the effects of Kinesiotape (KT), Mulligan's tape (MT) and no tape (NT) on knee and hip kinetics during landing in three turnout positions. The effect of taping on th...

Restorations of 98 implant-supported single crowns in anterior maxillary area were divided into 5 groups: zirconia abutment, titanium abutment, and gold/gold hue abutment with zirconia coping, respectively, and titanium abutment with metal coping as well as gold/gold hue abutment with metal coping. A reflectance spectrophotometer was used to evaluate the color difference between the implant cro...

The emphasis and direction of orthodontic treatment planning philosophies over the past century is a story almost all orthodontists are familiar with. In the latter part of the 19th century, Norman Kingsley, the leading orthodontist of the era, emphasized the esthetic objectives of orthodontic treatment. In the Kingsley paradigm, the articulation of the teeth was clearly secondary to facial app...

Previous research has shown that viewing images of nature scenes can have a beneficial effect on memory, attention, and mood. In this study, we aimed to determine whether the preference of natural versus man-made scenes is driven by bottom-up processing of the low-level visual features of nature. We used participants' ratings of perceived naturalness as well as esthetic preference for 307 image...
