Perio-prosthodontic pontic site management, part I: Pontic designs and their current applications

Emulating natural dentition with dental implant restorations is challenging, increasing its complexity when a pontic area must be restored. Many different methods have been described to solve this problem. The pontic designs which have been proposed have specific indications and may require additional treatments, including soft tissue augmentation procedures, to increase the possibility of an esthetically pleasing and biologically tolerable outcome. Proper conditioning of the soft tissues during the interim restoration stage and adequate communication with the laboratory are also critical factors to a successful outcome. This article describes the different approaches to restoring pontic sites with different degrees of complexity, their clinical indications, and limitations viewed from a perio-prosthodontic approach.

Different clinical scenarios for pontic sites require different approaches. Missing hard and soft tissues can be replaced by surgical or prosthetic means. Understanding the clinical indications and implications of the different pontic designs allows the clinician to make good decisions when planning and treating patients that require replacement of pontic spaces leading to more successful outcomes.

Different pontic designs have specific indications as well as biologic and esthetic prognoses. Selection of a good design, proper modifications during the provisionalization stage, and adequate communication with the dental laboratory will lead to higher chances of esthetic and biological success.

The proper pontic design allows for esthetically pleasing pontic sites which emulate natural emergence from the soft tissues while promoting biological stability.
