Summary

The aim of the present study is to evaluate the biting force of upper removable partial denture constructed from two different flexible thermoplastic materials.

Conditions

  • Biting

Interventions

OTHER

bre.flex

In the recent time thermoplastic materials become quite popular in clinical practice such as nylon and acetal resins. since the 1950, polyamide resin (nylons) provide improved esthetics and reduction of rotational forces on the abutment teeth due to their low elastic modulus(3). The major disadvantage of a nylon RDP is the inability for a reline procedure and the lack of occlusal rests as well as rigid frameworks, that could lead to occlusal instability and sinking, especially in Kennedy class I and II cases. On the other hand, acetal resins present adequate mechanical strength to form a frame-work more rigid than nylon with retentive clasps, connectors, and supportive elements; however, the acetal resin material lacks natural translucency and vitality.

OTHER

PEEK

PEEK has been successfully used over the last years in the medical field, and orthopedics, specifically. which presents high biocompatibility, good mechanical properties, high temperature resistance, and chemical stability due to a 4 GPa modulus of elasticity, it is as elastic as bone and can reduce stresses transferred to the abutment teeth.Additional advantages of this polymer material are elimination of allergic reactions and metallic taste, high polishing qualities, low plaque affinity, and good wear resistance, it has only recently been used in dentistry.
