Repairing mandibular body @entity174 presents unique challenges not encountered when repairing long bones. Large tooth roots and the presence of the @entity531 bundle limit safe placement for many types of orthopedic implants. Use of non-invasive @entity174 repair methods have increasingly become popular and have proven safe and effective at achieving bone healing. Non-invasive fixation constructs have not been tested in @entity235 using cantilevered bending. Furthermore, non-invasive @entity174 repair constructs have not been tested at the location of a common @entity174 location - the mandibular first molar tooth (M1). The objectives of this study were to test the strength and stiffness of three non-invasive mandibular @entity174 repair constructs and to characterize the impact that tooth crown preservation has on fixation strength for @entity174 occurring at the M1 location. Specimens were assigned to three treatment groups: (1) composite only, (2) interdental wiring and composite (IWC), and (3) transmucosal fixation screw and composite. For each pair of mandibles, one mandible received crown amputation at the alveolar margin to simulate the effect of crown loss on fixation strength and stiffness. Regardless of the status of crown presence, IWC demonstrated the greatest bending stiffness and load to failure. With the crown removed, IWC was significantly stronger compared to other treatments. All fixation constructs were stiffer when the tooth crown was preserved. In @entity174 at this location, retaining the tooth crown of M1 significantly increases stiffness of interdental wiring with composite and transmucosal screw with composite constructs. If the crown of M1 was removed, IWC was significantly stronger than the other two forms of fixation.
