Summary The purpose of this study was to evaluate the periodontal conditions of removable partial denture (RPD) wearers, comparing direct and indirect abutment teeth, and the teeth not involved in the denture design before denture placement and 1 year later.

Distal contours of pier a abutment • Key: Mesial side of the distal pontic 49. This includes definitive complete denture, framework partial denture, crown and bridge, inlays and onlays, porcelain veneers, and cast post and core. 1:50. A pier essentially consists of two parts i.ee a column shaft and the foundation. Pier Abutment/Intermediate Abutment • It is a natural tooth located between terminal abutments that serve to support a fixed or removable prosthesis. The preferred method of fabrication of most fixed partial dentures (FPDs) is rigid connectors between the pontic and retainers. Appropriate design in a RPD is critical for proper force distribution and avoidance of excessive loading of the periodon-tal ligament (PDL) of the abutment tooth [1]. Jivraj S, Chee W.

The pier abutment: a review of the literature and a suggested mathematical model. We have the inter-abutment axis to consider, the retentive differences in the crown preparations, and unwanted tooth movements, both physiological and when in function. Extension Based RPD’sDirect effect of rest placement on abutment teeth Open contact  If the rest is placed on the distal of the tooth adjacent to the edentulous extension area, when a posterior force is applied the tooth is tipped towards the edentulous area, resulting in an open contact with the adjacent anterior tooth  This tends to isolate the tooth making it more susceptible to bone loss and … Abutment teeth that require only minor modifications include teeth with sound enamel, those with small restorations not involved in the removable partial denture design, those with acceptable restorations that will be involved in the removable partial denture design, and those that have existing crown restorations requiring minor modification that will not jeopardize the integrity of the crown. called it the Bar Clasp.
