BACKGROUND: Utilization of attachments in a removable partial denture is highly essential not only as a line of treatment but also as it has a remarkable impact on the denture’s durability during the function. The attachment should act as a stress breaking system preserving the abutment teeth. AIM: This consideration aimed to verify the convention of polyether ether ketone (PEEK) material as an attachment. MATERIAL AND METHODS: Four groups of different materials for both attachments and partial denture framework were fabricated and tested using strain gauges to compare between them according to the strains originated around both the abutment teeth and edentulous area. RESULTS: PEEK material is one of the esthetic materials used for fabrication of the framework of the RPD. On using it as a precision attachement is shows favorable stress distribution decreasing the strains around the abutment teeth and the alveolar ridge especially distal to the abutment teeth that was significantly reduced in comparison with the other treatment options. CONCLUSION: Utilization of PEEK material as both an attachment and framework decline the strains performed around the abutment teeth and over the edentulous ridge.

“…Various values for the Young's modulus and Poisson's ratio of the trabecular bone in the anterior mandibular region were reported in literature: 1.37 GPa and 0.3 [23,24], 1.5 GPa and 0.29 [25], 2.5 GPa and 0.3 [26]. Additionally, different materials used as a replica for mandibular bone in vitro study were reported: acrylic resin, epoxy resin, polyurethane resin, polystyrene resin [16,19,27,28]. For this study, the self-curing acrylic resin used had a volumetric ratio of 3 parts powder to 1.5 parts of liquid, and presented elastic characteristics similar to those of the spongy bone from the anterior region of the mandible, as well as an average viscosity.…”

This paper is part of a larger study that aims to evaluate the biomechanical behaviour of mandibular bone and periodontal splinting systems subjected to different occlusal forces by means of electric resistive tensometry (ERT). The research was based on the following premise: the degree of bone resorption and periodontal type of splint influence the deformation of the mandibular bone. The study was conducted in two stages: first, the validation of the mandibular dental arch model, which is the subject of the present article, and second, the evaluation of mandibular bone strain in case of different types of bone loss and periodontal splints, which is the subject of a second article.

“…Most of the research work was directed to evaluate the effect of implant placement in distal extension cases on the abutment and the distal implant. Few studies were conducted to clarify the effect of different partial denture designs and attachments on the abutment teeth on the distal implant in unilateral distal extension cases (14,15) . In the current study, the effect of three different partial denture designs and attachments used on the abutment teeth was assessed on the marginal bone loss around the distal implant in Kennedy class II cases.…”
