Purpose: The aim of this study was to investigate how the physical variables of fibular reconstructed mandibles with dental implants affects the relative bite force in oral cancer patients.
Materials And Methods: Over 7 years of follow-up, 13 oral cancer patients were enrolled who included 51 successful implants in the fibular flap. The tactile sensor analyzer evaluated the bite force. The crown-implant ratio, fibular, and rehabilitated dental length were measured using radiographic images. Linear regression was used to analyze the bite force related to the variables of the implants in the fibular reconstructed mandible.
Results: Even when the results showed no statistical significance (P > 0.05), increasing the crown-implant ratio, length of the fibular flap, and implant prosthetic reconstructed dentition had a tendency to decrease the bite force (estimate from -0.08% to -4.27%); there was a positive trend of occlusal force and the length of rehabilitative dentition compared with the dental antagonist (estimate = 6.95).
Conclusion: In this study, the crown-implant ratio, implant dentition, and fibular flap length revealed no significant impact on the bite force or implant success in oral cancer patients; however, a trend to weaken the bite force was suggested once the numerical values of these variables increased.

Background: The selection guideline for the implant-supported bar connectors (ISBC) of hybrid denture is lacking. This study investigated the maximum von Mises stress (vMS), stress distribution, and displacement of various geometric ISBC in mandibular hybrid dentures, as well as the maximum principal stress (σmax) in the acrylic resin part, through finite element analysis.
Methods: Four different geometric cross-sectional patterns for mandibular ISBC-L, Y, I, and Square-of equal volume, based on the "All-on-4" concept, were created.
Experimental study on optimization of pipe jacking mud mixture ratio based on MICP technology.

In the course of pipe jacking construction, the carrying-soil effect frequently arises, influenced by factors such as excavation unloading, ongoing disturbance from successive pipe sections, and the progressive accumulation of soil adhesion. The pipe jacking slurry serves as a critical agent for friction reduction and strata support, essential for the secure advancement of the construction process. This study introduces the Microbial-Induced Calcium Carbonate Precipitation (MICP) technology into the realm of pipe jacking slurry, aiming to enhance its friction-reduction capabilities and the stability of the soil enveloping the pipe.

Objectives: To evaluate various oral functions in patients with jaw defects after oral tumour surgery and to clarify factors associated with their quality of life (QoL).
Background: In patients with jaw defects, oral function and QoL are severely impaired. No studies have evaluated oral functions of patients with jaw defects and examined their relationships with QoL.

Purpose: To analyze the safety of closed traction appliance in the treatment of impacted anterior teeth and its effect on pulp blood flow and masticatory function.
Methods: A total of 80 patients with impacted anterior teeth who received treatment from January 2017 to December 2022 were selected, and randomly divided into experimental group and control group with 40 cases in each group. The two groups of patients were treated with occlusion adjustment and orthodontic traction.

The Aim Of The Study: Was to determine the possibility of calculating the parameters of the occlusal surface of fixed dentures.
Materials And Methods: An analysis of dependence between the area of the occlusal surface and the area of the support structures (tooth root/implant), between the severity of the occlusal relief (tubercles of teeth) on the length of the root/implant was carried out.
Results: The nearness of the Kurlandsky periodontal coefficients and Oksman masticatory coefficients with the calculated coefficients obtained on the basis of 3D analysis of the lateral teeth anatomy has been established.
