presents a case in which rigid attachments were used as a mode of retention keeping
in mind patients esthetics, function and financial conditions. Patient name
Girjamma, 38 years old presents with the chief complain of missing maxillary
anterior teeth (11,12,21) and posterior teeth (15,16,17,26,27) due to caries which were extracted 6 months
ago. On intraoral examination periodontal condition of remaining teeth were
found to be good. Treatment planning of anterior 9 unit FPD considering 6 abutment
teeth with attachment supported CPD was made depending on patient financial
impressions were made using alginate (3M ESPE) and poured using type 3 gypsum product (Kalabhai Kalstone). Diagnostic
maxilla mandibular relation was recorded and casts were articulated. Wax pattern with acrylic teeth for anterior FPD was
tried in patient mouth for approval.
consent from patient crown preparation were done i.r.t 13, 14, 22, 23, 24, 25
followed by gingival retraction using foam cord and compri cap was done and
final impression made using monophase silicone impression material. Temporary
bridge was given on the same day using Protemp temporary material.
Metal framework try-in with Rhein
83 attachments was done in patient mouth and after proper shade selection final porcelain build up on framework was done. Upon
bisque try in of framework zenith marking intra orally for pink porcelain
build-up was done using lead pencil .Framework
pick-up was done for fabrication of CPD framework. Anterior FPD was cemented
using GIC cement and CPD framework try in was done followed by jaw relation
record with the framework. CPD try in was done and final CPD insertion with was
In present case Rhein 83 (OT Cap)
attachment were used. With cases involving edentulous saddles, resiliency can
be controlled with a wide range of retentive caps that have various levels of
elasticity and retention.
OT Cap is a resilient distal extension attachment. It is indicated
to be used with combined prostheses and removable partial dentures. For
treatment plans that require a rigid substructure with milling and adequate
counter attachments, OT Cap functions as a stabilizing retentive connector. In
addition, for treatment plans which require resiliency, OT Cap provides a
“Cushion Effect” similar to a shock absorber. This is achieved by the design of
the sphere in conjunction with the elastic retentive caps.
