Background: Stress concentration may cause bone resorption even lead to the failure of implantation. This study was designed to investigate whether a certain sagittal root position could cause stress concentration around maxillary anterior custom-made root-analogue implants via three-dimensional finite element analysis.Methods: Six models were constructed and divided into two groups. The smooth group included models of unthreaded custom-made implants in Class I, II or III sagittal root positions. The threaded group included models of reverse buttress-threaded implants in the three positions. Stress distributions under vertical and oblique loads of 100 N were analyzed.Results: Stress concentrations around the labial lamella area were more prominent in the Class I position than in the Class II and Class III positions under oblique loading. Under vertical loading, the most obvious stress concentration areas were the labial lamella and palatal apical areas in the Class I and Class III positions, respectively. Stress was relatively distributed in the labial and palatal lamellae in the Class II position. The maximum von Mises stress in the bone around the custom-made root-analogue implants in this study was lower than around traditional implants reported in the literature. Additionally, compared to the smooth group, the threaded group showed lower von Mises stress in the bone around the implants.Conclusions: The sagittal root position affected the von Mises stress distribution around custom-made root-analogue implants. There was no certain sagittal root position that could cause excessive stress concentration around the custom-made root-analogue implants. Among the three sagittal root positions, the Class II position would be the most appropriate site for custom-made root-analogue implants.

“…A piezoelectric transducer is a kind of transducer that uses the piezoelectric effect of a piezoelectric material to convert the measured pressure into an electric signal. Its sensitive element is made of piezoelectric material (Bing et al, 2020). Piezoelectric materials in piezoelectric sensors generally include piezoelectric crystals (i.e., quartz crystals), piezoelectric ceramics, and polymer piezoelectric materials (González et al, 2016).…”

In dental research, bite force has become an important curative effect evaluation index for tooth restoration, periodontal treatment, and orthodontic treatment. Bite force is an important parameter to evaluate the efficacy of the masticatory system. Physicians obtain the therapeutic basis for occlusal adjustment by measuring the bite force and the dynamic changes in occlusal contact at different stages of treatment and objectively evaluate the therapeutic effect. At present, many devices are used to record the bite force. Most of these devices use force transducers to detect bite force, such as strain gauge transducers, piezoresistive transducers, piezoelectric transducers, optical fiber transducers, and pressure-sensitive films. This article summarizes the various equipment used to record bite force, related materials and the characteristics of this equipment. It provides a reference for physicians to make choices during the clinical process and at the same time provides a basis for the development of new occlusal force measurement materials.

“…The presence of an adequate crestal bone level has been considered an important clinical determinant for the longterm success of implant treatments 1-3 because loss of bone from the peri-implant ridge will significantly affect the biomechanical anchorage of the prosthesis and may compromise treatment longevity. 4 Implants with different cervical designs and platforms have been proposed to maintain the health and quantity of periimplant tissues. Platform switching, where the implant diameter is greater than the abutment diameter, was first described by Lazzara and Porter in 2006.…”

Marginal bone loss associated with dental implants is a major concern and clinical challenge, as the resistance to fracture of implants when in function (receiving loads) is given by the set formed between the walls of the implant and the amount of bone tissue around the walls. The presence of an adequate crestal bone level has been considered an important clinical determinant for the longterm success of implant treatments 1-3 because loss of bone from the peri-implant ridge will significantly affect the biomechanical anchorage of the prosthesis and may compromise treatment longevity. 4 Implants with different cervical designs and platforms have been proposed to maintain the health and quantity of periimplant tissues. Platform switching, where the implant diameter is greater than the abutment diameter, was first described by Lazzara and Porter in 2006. 5 The level of bone remodeling or resorption around dental implants is influenced by surgical aspects,
