Abstract
Dental implants stabilize the removable partial denture in a vertical direction and minimize the resultant rotational movement. The clasp design may affect the loads transmitted to the abutment teeth and implants.. Aim: The aim of this study was to clinically evaluate the effect of clasp design on tissue health around abutment teeth and implants assisting mandibular bilateral distal extension removable partial overdenture. Material and Methods: Ten healthy patients with completely edentulous maxilla opposed by partially edentulous mandible with first premolars and six anterior teeth remaining were selected.Single implants were placed bilaterally at the first molar area, and the metallic framework was designed. According to the clasp design patients were grouped. Group I: Aker clasps were constructed on the first premolars.Group II: Reverse Aker clasps were constructed on the first premolars. Clinical evaluation parameters that included; Plaque index, Bleeding index, Gingival index, Probing depth, and Mobility were performed immediately before insertion and three & six months after insertion of the definitive prosthesis Results: found that:- the abutment teeth in group (I) recorded higher (GI), (BI), (PTVs) values compared to those in group (II) and the differences were significant(P <.05). implants in group (I) recorded higher (GI), (BI), (PTVs) values compared to those in group (II) and the differences were significant (P <.05). Conclusion: In comparison to Aker clasps, the reverse Aker clasps are considered better in regard to the preservation of abutment teeth and oral tissue health around the implants located in the first molar area for assisting mandibular bilateral distal extended removable partial overdenture.
