However, this protection was not noticed in patients with other types of SCD. To evaluate the effect of prosthetic framework material and cantilever length on peri-implant strain in mandibular all-on-four implant-supported prostheses with different types of arch antagonist forces. Models simulating a completely edentulous mandibular arch fabricated in heat-cured acrylic resin were used. On the acrylic models, four implants were placed at regions 34, 32, 42, and 44 simulating all-on-four implant placements. Implant-supported screw-retained fixed prosthesis frameworks were fabricated using three different materials (cobalt-chromium, zirconia, and polyetheretherketone) and with three different cantilever lengths (zero mm, 15 mm, and 25 mm). Strain gauges were attached on the model at the buccal and lingual positions of each implant. Forces simulating opposing natural dentition, conventional complete denture, and the parafunctional habit were applied to the models. The peri-implant strain in each strain gauge was recorded. Least peri-implant strains (67 microstrains) were observed whs well as the cantilever length, should be altered based on the forces from the opposing arch. Rehabilitation of a single, completely edentulous arch with implant-supported prostheses should consider the situation of the opposing arch. The choice of framework material, as well as the cantilever length, should be altered based on the forces from the opposing arch. Episiotomy is a deliberate surgical incision of the perineum with the aim of increasing the vulval outlet to facilitate childbirth. However, it could be associated with some complications, such as pain, hemorrhage, and wound infection. It is a surgical procedure that requires adherence to basic surgical principles of providing adequate analgesia. To d
