Retruded Contact Position


With In the context of clinical dental practice, the relationship within three dimensions related to the mandible of the maxilla augmented with the appreciative of the clinicians is mostly considered to be indispensable. The reason behind this is that during the mandibular movement, the teeth tend to slide over one another. However, understanding the important concepts of occlusion should allow dentists and technicians in avoiding the majority of the dilemmas linked with the prerequisite of crowns, partial dentures or complete dentures. Problems concerning ceramic rupture, retention loss and fracture of tooth were indirectly related to parafunctional or occlusal aspects. Prosthetic dentistry takes in the power to bring about an alteration in the occlusion of patient.

Occlusion is known as the statistic relationship between one or more maxillary and mandibular teeth. Planned occlusal restoration can prevent the failure potentially of restorations where occlusal changes are inevitable due to prosthodontic treatments. It is also required to achieve a stable posterior occlusion along with smooth uninterrupted protrusive and lateral excursions. The retruded contact position in occlusion is of use in the curative treatment of edentulous and dentate persons for the reason that its comparatively reproducible situation (2). Tooth contact in the retruded contact position (RCP) is an imperative maxilla-mandibular relationship in dentistry. The importance of the retruded contact position will be discussed in details, and will take into account its significance and usage in the treatment of dentate and edentulous patents. Beside that the diagnostic phases and techniques employed to get hold of a record of RCP will be obtainable.

Centric Occlusion (CO) & Centric Relation (CR)

The significance of centric occlusion (CO) is that the occlusal forces are directed axially, as well as it's an end point of chewing cycle, and the position in which simple restorations are made. Centric occlusion is simply characterized as the “occlusion of contrasting teeth” while the mandible is in middle connection (3). The location of the mandible as the condyles are in their mainly posterio-superior opaque positions in the glenoid fossae, termed as centric relation (CR). The centric relation is Repeatable, Reproducible, and Recordable(4).

Intercuspal position (ICP) - Retruded contact position (RCP)

When patients of dentate enquired only to nibble simultaneously on their posterior teeth, they put up the shutters instantaneously into a relaxing reproducible congested pose where the highest figure of contacts of tooth occurs; it is termed as “intercuspal position (ICP)”. The guided of relationship of occlusion taking place at the major retruded situation of the condyles in the cavities of joint, which is a site that could be extra retruded comparing the position of central relation. This location denoted as “retruded contact position (RCP)”.

It is commonly acknowledged that in the majority of persons with an innate dentition, an undersized pathway of progress amid the intercuspal position and the retruded contact position is present in an intro-posterior route, and that both of these positions of occlusion are frequently utilised throughout execution. The movement from RCP to ICP is called ...
