Twelve months after being released from the hospital after contracting COVID-19, patients show notable changes in comparison to those who did not have the virus, as evidenced by a number of indicators, including a dry mouth, decreased taste perception, bleeding gums, discomfort during meals, a decline in emotional health, communication diffi culties, and less meticulous oral hygiene. Both the severity of the coronavirus infection and overall health were found to be negatively correlated with the likelihood of caries and dry mouth, respectively.

   Dental malposition and malocclusion are two common dental diseases that have a major negative infl uence on patients' quality of life. The process of alveolar bone remodeling is the basis for orthodontic tooth movement. In order to prevent complications like fenestrationsт and dehiscences, treatment planning necessitates a comprehensive evaluation of the biological boundaries established by alveolar bone shape. Cone beam computed tomography (CBCT) is one of the modern diagnostic techniques that greatly improves the assessment of the dentofacial system. CBCT is a useful tool for precise diagnosis and orthodontic treatment planning because it offers high-resolution, three-dimensional imagery with little radiation exposure. Sources and Techniques: Cone-beam computed tomography was performed on 120 patients who had malocclusion. This article's goal is to examine how well CBCT can evaluate the shape of alveolar bone in order to maximize orthodontic treatment. Results and Discussion: In order to maintain the volume of buccal and lingual alveolar bone and maintain periodontal integrity, natural physiological processes encourage dentoalveolar compensation.

   To identify the kind of face skull growth, the study used a novel technique based on the following angular parameters: N-Po-Pg, Po-N-Pg, Po-Go-Pg, Po-N-A, Po-N-B, and M. Forty mesial occlusion patients, ages 18 to 40, were enrolled in the study. Clinical photography and lateral cephalometric head radiographs were used as diagnostic techniques. The statistical examination of the previously indicated angular parameters was one of the research aims. Furthermore, based on the kind of facial skull growth, the cumulative angle in patients with mesial occlusion was analyzed and its values were determined. By improving the accuracy of facial skull evaluation, the use of this assessment approach may improve treatment prognosis.

   The results of a morphometric examination of a patient's face profi le using a computer-based evaluation for distal occlusion are presented in this paper. The facial aesthetic criteria with the biggest variations were found. Changes seen on lateral cephalometric radiographs were contrasted with the data that was acquired.

   An examination of the relationship between facial soft tissue and skeletal characteristics in patients with the gnathic form of mesial occlusion is presented in this paper. The 42 patients, who were categorized into three development types – neutral (12 individuals), horizontal (20 individuals), and vertical (10 individuals) – were all between the ages of 18 and 35. Clinical evaluation, lateral cephalometric radiographs, and profi le photos with the head centered on a cephalostat were all part of the examination. The analysis revealed that in patients with mesial occlusion, there were both positive and negative correlations between the skeletal and soft tissue components of the face profile.

   Before beginning the active treatment phase, individuals with distal occlusion who have infantile tongue position must normalize it; otherwise, the orthodontic treatment's dynamics and fi nal outcome may be impacted. In order to achieve self-regulation and, if required, to move forward with an active period of hardware orthodontic treatment in order to achieve an effective and stable result, a navigator or device to normalize tongue position is used in conjunction with a developed set of myogymnastic exercises. The tongue can easily rest on the palate without coming into contact with it thanks to a non-removable structure that is situated on the palate and does not decrease the intraoral space. It ensures a dense and balanced distribution of pressure on the palate by providing navigation for the tongue without distorting the creation of sound. The absence of traumatic (sharp) components in the device stops the tongue from using avoidance strategies that might compromise the effectiveness of treatment.

   In orthodontic practice, cone-beam computed tomography, or CBCT, is a crucial diagnostic technique. It is possible to assess how bone structures change over time following therapy by superimposing CBCT pictures. To avoid errors caused by shifting bone marker positions, CBCT images can be superimposed using certain algorithms. In this paper, we outline a technique for superimposing (overlaying) CBCT pictures of patients before to and following subzygomatic screw orthodontic therapy.

   Evaluating how well low-level laser therapy accelerates orthodontic tooth movement in individuals with distal occlusion was the study's goal.

   30 patients with a diagnosis of distal occlusion, ages 25 to 40, were included in the study. They were split into two groups: the main group (n = 15), which received low-level laser therapy along with aligners for orthodontic treatment, and the control group (n = 15), which only received standard protocol. Cone-beam computed tomography (CBCT), dental photometric analysis following a defi ned protocol, molar distalization measurement, and tracking the time to normal occlusion were among the evaluation criteria. The study's goals were to compare the dynamics of molar distalization in the main and control groups, assess the clinical effi cacy of low-level laser therapy in speeding orthodontic tooth movement, and investigate the impact of low-level laser radiation on the length of orthodontic treatment.
