Periodontal acrylic veneer

Definition A facing that is placed buccal to the natural dentition and constructed in acrylic resin. It masks any recession or postsurgical tissue loss that is present and gives the appearance of a normal gingival contour and level.

Management Such a prosthesis should only be constructed for a patient whose oral hygiene is good and whose periodontal condition is controlled. Veneers utilise both the interproximal area of the dental arch together with salivary adhesion for their retention. They should not be worn when sleeping on both periodontal health and medico-legal grounds.

Advantages  The major advantage of this appliance is the improvement in appearance that can be achieved particularly in a patient who has a high lip line. This veneer can also have the beneficial action of  improving speech, as often patients who suffer from marked anterior recession feel that a   ‘whistling’ problem can result during speech due to the development of large interproximal spaces. If these are filled by such an appliance, the problem is normally resolved.

Disadvantages Like most prostheses there is the potential for increased plaque accumulation if the patient does not maintain a high level of oral hygiene.

Procedure A special impression tray which supports a buccal impression is used. The impression is taken from a buccal path of insertion/withdrawal and modern elastomers can cope effectively with the undercut areas.
