“…In vitro tests should therefore consider using less supportive foam or leaving the apex unsupported for better simulation of the clinical conditions of an injured tooth. Artificial maxillary models used in in vitro experiments have often used resin‐based 17,19,20 or stainless steel 5,6 materials to represent the maxillary bone anatomy. However, the mechanical bone response is important, especially during high load applications (1000 N) where deformation and distortion can affect the relative movements of the teeth and the alveolar bone.…”

“…Different dental splint materials have been described for first‐aid treatment of dental trauma injuries 15 . Wire‐resin composite splints (WCS), using 0.45 mm or thicker metallic wires, are most commonly mentioned for rigid fixation, while nylon‐resin composite splints (NCS) are known as flexible splints 16,17 . However, little is known about the effect of these materials in the mixed dentition when adjacent teeth are missing.…”

Background/Aims Dental traumatic injuries are common in children during the mixed dentition stage. These injuries usually require splinting for stabilization, which is complicated by the various stages of the permanent tooth development and primary tooth exfoliation. The aim of this study was to evaluate the effect on mobility of splint materials and extensions for an avulsed central incisor, stabilized with and without the adjacent incisor under intrusive and extrusive loading with different periodontal ligament (PDL) conditions. Materials and Methods Seventeen 3D model variations were created from a CBCT scan of a 7‐year‐old patient without erupted permanent upper lateral incisors. A 1000 N palatal load on the right central incisor simulated the avulsion injury and created an increased alveolus and bone deformation, resulting in an increased PDL thickness of 0.45 mm. Wire‐resin composite splints with 0.9 mm cross‐section (WCS) or 1.0 mm diameter nylon‐resin composite splints (NCS) were created. The models simulated conditions with and without the adjacent upper central incisor. Two PDL conditions were investigated, simulating detached PDL or PDL with polyether impression material‐like properties. Mobility was calculated under simulated biting loads in horizontal and vertical (intrusive and extrusive) directions. Results The NCS allowed greater tooth mobility of the avulsed incisor than the WCS, irrespective of splint extension, PDL condition, or load application. During horizontal loading, polyether‐like properties for the PDL allowed around 0.2 mm mobility of the avulsed tooth with the WCS, similar to the intact tooth, whereas a simulated detached PDL allowed 25% more mobility with a WCS than with a NCS. Conclusions Based on the FEA analysis, a 1.0 mm NCS may be suitable for splinting avulsion injuries during the mixed dentition stage compared to the considerably more rigid WCS. The NCS models provided flexibility for PDL healing while maintaining stability, even when missing adjacent teeth increased span widths. Extensions beyond directly adjacent teeth did not alter the mobility with the NCS but should still be considered an extra protection in case of bond failure or exfoliation.

“…Published by Francis Academic Press, UK -126-Paz et al [33] created a fracture model of alveolar process using a cattle incisor tooth to simulate the maxillar incisor tooth, and used a deflection meter to measure displacement in the fractured and adjacent central incisor area under functional cycle and static load. It was found that using a wire of at least 0.9mm could effectively reduce the displacement of the fractured alveolar process to a level similar to that of adjacent teeth.…”

Tooth dislocation injury is a more common type of dental trauma, which is commonly caused by sports accidents, traffic accidents, falls, family accidents and increasingly common attacks. The purpose of treatment is to restore function by splinting in time. Splint will fix the injured tooth and the healthy teeth on both sides into a whole, so that the force is dispersed on a group of teeth, so that it forms a multi-rooted tooth. After dislocation injury, the displaced tooth must be restored to the normal position as soon as possible and fixed in time. Elastic and semi-elastic splints are mostly used in clinical fixation. The update and development of materials make the selection of fixation diversified. This paper will review the types and research progress of splint materials that meet the indications of tooth dislocation injury, in order to provide reference and guidance for clinical work.

“…Eventually, they concluded that this composite is a promising candidate for minimizing the cost and duration of dental implant surgery. Apart from the composition, other variables must be considered in this field; for instance, previous studies have demonstrated that the rigidity of the composite was an important factor influencing the mobility of the fractured alveolar process, and the use of at least a 0.9 mm wire reduced the fractured alveolar process displacement [ 116 ].…”

Polymer-based composites are a group of biomaterials that exert synergic and combined activity. There are multiple reported uses of these composites in multiple biomedical areas, such as drug carriers, in wound dressings, and, more prominently, in tissue engineering and regenerative medicine. Bone grafting is a promising field in the use of polymeric composites, as this is the second most frequently transplanted organ in the United States. Advances in novel biomaterials, such as polymeric composites, will undoubtedly be of great aid in bone tissue engineering and regeneration. In this paper, a general view of bone structure and polymeric composites will be given, discussing the potential role of these components in bone tissue. Moreover, the most relevant jawbone and maxillofacial applications of polymeric composites will be revised in this article, collecting the main knowledge about this topic and emphasizing the need of further clinical studies in humans.
