Retention of Peek and Bre.Flex Materials Maxillary Bilateral Bounded Removable Partial Dentures

Retention Clinical Trial

Official title:
Comparative Study of Retention of Peek and Bre.Flex Materials Maxillary Bilateral Bounded Removable Partial Dentures .(Randomized Clinical Trial).

Clinical Trial Summary

Evaluation of the retention of upper removable partial denture constructed from two different flexible thermoplastic materials.(BRE-FLEX and PEEK).

Clinical Trial Description

The assessor is responsible for all clinical procedure that will be conducted in this study during all the visits:

Panoramic radiograph and periapical radiographs will be made on the prospected abutment teeth to evaluate the crown-root ratio, the apical condition of the abutment and their alveolar bone support.

The preliminary impression will be performed with irreversible hydro-colloid impression material (alginate), The impressions will be poured with type IV dental stone to obtain diagnostic casts. Maxillary Face-bow will be recorded. The diagnostic casts will be mounted on semi adjustable articulator in centric occluding relation to evaluate the interarch distance and occlusal plane.

Special trays will be constructed and Mouth preparation will be performed by preparing guiding planes and rests seats will be prepared opposing to the edentulous area.

Final impression will be taken by elastomeric impression material. The impression will be poured into type IV dental stone in order to obtain master cast. The master cast will be surveyed. The proposed design will be as follows: metal framework base saddle for edentulous areas on both sides connected with palatal strap. Aker's clasp on all abutments with buccal retention. The denture base will be tried in with acrylic teeth in patient's mouth. After that, the denture base of the partial denture will be processed incorporation with the metal framework into the two different materials to be evaluated. The first group will receive the partial denture in which the metal framework incorporated with the denture base fabricated from PEEK material. The second group will receive the partial denture in which the metal framework incorporated with the denture base material fabricated from BRE-FLEX ;
