Objective: This study aimed to evaluate the retention of acetate resin clasp as when compared to metal clasp. Material and methods: For this purpose, we constructed 10 conventional Co-Cr metal clasps (Ackers) and 20 acetate resin clasps. The acetate resin clasps had the opposition, support and retaining arms made of Co-Cr. Of the 20 esthetic clasps, 10 had the thickness of the retention arm decreased to make it more esthetic. The initial retentive force of the specimens was tested in a universal testing machine through tensile test. After that, the specimens were subjected to 7,000 cycles, each one, in an adapted machine, immersed into artificial saliva, for 36 months of simulated clinical use of a removable partial denture. Data were tabulated for statistical analysis of the retention effectiveness. Results: After cycling, 3-mm-thick and 2-mm-thick acetate resin clasps lost more retention than metal clasps. The material type (p=0.0000) and cycling (p=0.0039) showed a significant effect, but the material/cycling interaction (p=0.1436) did not. Conclusions: Therefore, esthetic clasps presented retention force lower than that of metal clasps. Notwithstanding, the esthetic clasps can be used in clinical cases requiring minimum retention.

“…The rotational path design concept uses a rigid retainer portion of the framework as the retention component 11. The proximal plate provides retention through its intimate contact with the proximal tooth surface below the height of contour at a zero-degree tilt.…”

“…There are three basic types of rotational path RPDs: anterior-posterior (AP), posterior-anterior (PA), and lateral. Jacobson and Krol narrowed the rotational paths to two categories 11. Category I includes all prosthesis designs that first seat the rest that is associated with the rigid retainer.…”

“…Category II includes all lateral paths and AP paths that replace anterior teeth. The centers of rotation and the rigid retainers are located at the gingival extension of minor connectors 9,11. These prostheses use a dual path of insertion: at first RPD is inserted straightly from an incisal or occlusal direction to the rotational centers and then the conventional posterior or contralateral retainer is rotated into position.…”

“…It is important that the initial straight path of insertion must be parallel with the cingulum rests to permit complete seating. The rotational path RPD offers the advantages of improved esthetics by eliminating anterior clasps, shortened treatment duration, cleanliness, and lower treatment cost over implants or fixed partial dentures 5,6,11…”

BACKGROUNDThough implant dentistry is very successful and predictable in treatment of patients with destroyed dentition, there are some cases with limitations to implant therapy. In these cases, alternative treatment modality should be considered.CASE DESCRIPTIONA patient with destroyed dentition was rehabilitated with a lateral rotational path removable partial denture. According to the diagnosis, we determined to raise vertical dimension for esthetic and functional restoration. The final restoration was performed after four months of provisional period.CLINICAL IMPLICATIONThe edentulous patients with compromised esthetics and functions can be successfully treated with a rotational path removable partial denture through adequate treatment planning and precise laboratory procedure.
