Numerical and biomechanical analysis of orthodontic treatment of recovered periodontally compromised patients

The combined orthodontic and restorative treatment for patients with malocclusion and dentition defects: A randomized controlled trial

“…[3] Currently, routine restoration measures are often used in clinical practice to intervene in patients with malocclusion and dentition defects, which can achieve certain results. [4] However, during the restoration period, there may be problems such as difficulty in making the restoration, mismatched appearance, etc, which make it difficult to fully meet the actual needs of patients, and the recovery status of the periodontal body is difficult to meet clinical expectations. [4,5] With the deepening of clinical research, it has been found that orthodontic treatment based on conventional restoration can form a good periodontal relationship with adjacent teeth and completely preserve the alveolar bone at the top and buccal edges of the alveolar ridge, thereby improving oral chewing and occlusal function.…”

[6,7] Therefore, this study aimed to identify 112 patients with malocclusion and dentition defects in our hospital for grouping research, with the aim of clarifying the impact of a combination of orthodontic and restorative treatments on chewing, swallowing, and language function, in order to provide new insights and a reference basis for the clinical treatment of malocclusion and dentition defects.…”

Biomechanical Simulation of Orthodontic En-Bloc Retraction Comparing Compound Technique and Sliding Mechanics Using a HOSEA Robotic Device

“…In addition to retractive forces F x and torsional moments M y , collateral forces and moments were measured, in particular an extrusive component F z (Figure 8, Table 2). The occurrence of an extrusive force component during retraction has been described in literature [21,36]. For this reason, it is recommended to apply compensatory bends during or after retraction [20,36].…”

“…The occurrence of an extrusive force component during retraction has been described in literature [21,36]. For this reason, it is recommended to apply compensatory bends during or after retraction [20,36]. In this study the aim was to focus on the forces and moments during en-bloc retraction, thus compensatory bends were not applied.…”

“…In addition, the experimental model used in this study consisted of two solid segments, without allowing to account for individual tooth mobility. However, even if the teeth are combined to a block using figure-8 steel ligatures, individual tooth mobility remains [36]. The setting did not include saliva, which can influence frictional behavior and thus affect the measured values [40].…”
