Pónticos ovoides en el manejo de tejidos blandos, zona posterior con y sin extracción: reporte de dos casos clínicos / Ovate pontics in soft tissue management, posterior zone with and without extraction: report of two clinical cases

Un problema que sucede a menudo en la práctica clínica es la ausencia dental por diversos factores. Esto conduce a un gran desafío para surehabilitación, ya que debido a la pérdida dentaria se genera un colapsodel reborde alveolar, lo que ocasiona alteración en la morfología óseay gingival, o en diversos casos, se realizaron extracciones sin una planeación restaurativa, por lo que su sustitución implica mayores procedimientos. Una alternativa a esta ausencia dental es el diseño de póntico ovoide, siempre y cuando cumpla los requisitos clínicos para un mejor resultado estético, funcional e higiénico. El objetivo de este artículo es mostrar el empleo del póntico ovoide en el sector posterior con distintos aspectos clínicos: por un lado, utilizando la técnica de conformación del lecho gingival a presión y por el otro, la técnica directa postextracción, mediante prótesis fija de tres unidades en metal/porcelana.

A problem that often occurs in clinical practice is the dental absence caused by various factors. This leads to a great challenge for rehabilitation since due to tooth loss, a collapse of the alveolar ridgeis generated, causing an alteration in bone and gingival morphology; also, in many cases, extractions were made without restorative planning, so their replacement involves major procedures. An alternative to this dental absence is ovate pontic design, provided it meets the clinical requirements for better esthetic, functional and hygienic result. The aim of this article is to show the use of the ovoid pontic in the posterior region with different clinical aspects: first, using the technique of forming the gingival bed under pressure and on the other, postextraction direct technique through a three-unit fi xed prosthesis in metal/porcelain.

The esthetic prosthodontic treatments in maxillary anterior area, considering the gingival margin / 대한치과보철학회지

To enhance the esthetic appearance, the maxillary anterior area is important. It is possible to improve the esthetic appearance through the treatment of maxillary anterior area, which includes altering the color, form, and arrangement of teeth. When planning these treatments, clinicians should individualize personal demands, by using the information obtained from facial, dento-labial, dental, and gingival analysis. It is essential to properly prepare the gingival structure, which includes the height of gingival margin, the location of zenith, reconstruction of the interdental papillae, emergence profile, and symmetry. Clinicians often face unfavorable condition of the gingiva and the edentulous ridge, and appropriate management of the gingival structure is needed. In this case report, the patients were treated to improve the gingival conditions surrounding maxillary anterior teeth. By using conservative treatment without surgical intervention, such as application of pink porcelain, subgingival contour modelling and modification of pontic base, satisfactory esthetic results were gained.

“Ovate Pontic”- Esthetic Enhancement of the Anterior Restorations.

Esthetics is of prime concern when replacing any anterior tooth. The prosthesis should resemble the adjacent natural tooth closely. Out of many types of pontic designs, ovate pontic may serve the purpose of providing good esthetics and phonetics. It will maintain interdental papilla and help to maintain good gingival health. In addition to it ovate pontic has an advantage of immediately replacing the missing anterior tooth.
