Management of a Patient with Angle Class I Malocclusion with Anterior Crossbite and Maxillary Central Diastema Caused by High Attachment of the Maxillary Labial Frenulum

Maxillary Central diastema is common and normal for the growth and development of the anterior segment. If the central diastema persists after the eruption of the permanent cuspids, the orthodontist should clarify the etiology and establish a treatment plan. This case report discusses a 22-year-old woman with anterior crossbite and central diastema due to a high maxillary labial frenulum attachment. Treatment was performed using a fixed orthodontic appliance with a posterior bite raiser. Frenectomy was performed at the end of the orthodontic treatment.

Oral Impacts of Aligners versus Fixed Self-Ligating Lingual Orthodontic Appliances

The aim of this prospective study was to compare a fixed lingual orthodontic appliance with a commonly used aligner system, focusing on oral impacts and speech disturbances, during the first 3 months of orthodontic treatment. Two groups of adults were evaluated: 21 treated with Invisalign® and 26 with In-Ovation L® lingual brackets. Health-related quality of life questionnaires were used to assess the oral impacts, and speech samples were collected for speech evaluation by professionals. The levels of pain and painkiller intake were similar, increasing on the first day, and decreasing at 3 months. Subtle injuries on the lip and cheeks were initially reported in the aligner group. Lingual patients experienced more discomfort in swallowing and opening the mouth, tongue injuries and food residues, even at 3 months. The consonants “s” and “z” were mainly affected in both groups immediately after appliance insertion, but more often in the aligner group. These speech disturbances recovered in the following 3 months. In conclusion, both groups reported disturbances in quality-of-life measures; however, patients wearing lingual appliances experienced more disturbances, which persisted after three months. Speech disturbances were slightly more pronounced in the aligner group and recovered after three months.

Diet and orthodontics- A review

During the course of fixed orthodontic therapy, patients should be instructed to eat specific food stuffs and beverages in order to maintain good health for the dentition and supporting structures and prevent frequent attachment debonding that prolong the treatment duration. After searching and collecting articles from 1930 till July 2021, the current review was prepared to emphasize various types of foods that should be taken during the course of fixed orthodontic therapy and to explain the effect of various food stuffs and beverages on the growth and development of craniofacial structures, tooth surfaces, root resorption, tooth movement, retention and stability after orthodontic treatment and the effect on the components of fixed orthodontic appliance.

Simulation of superelastic NiTi wire force application on orthodontic alignment case

Nickel Titanium (NiTi) orthodontic wires are the most accurate initial wires to align the teeth by producing the less painful bone remodeling. Coupling their mechanical response, while they are engaged in the oral cavity, with the bone remodeling would permit to elucidate the reaction and the effect of this wire during the orthodontic tooth alignment. Therefore, A two-dimensional numerical long-term orthodontic tooth correction was performed to simulate a tooth intrusion movement. This simulation was achieved by taking into consideration the effect of an orthodontic appliance action on three multiteeth models. The superelastic behavior of the NiTi wire was integrated in the computer software ABAQUS via a UMAT subroutine. The orthodontic arch was initially deformed to simulate its insertion in brackets and then unloaded to apply an orthodontic load and produce initial tooth displacement. A bone remodeling process was implemented to displace the teeth depending on the strain within the periodontal ligament. The results were obtained for a treatment period of 30 days. The NiTi wire was able to recuperate its initial position, and the teeth were aligned. The numerical results of the teeth displacement were in agreement with what is expected to be produced during the alignment phase.

Assessment of Gingival Health Status among Patients with Fixed Orthodontic Appliance

Fixed orthodontic appliances corrupt plaque removal, proper oral hygiene, and gingival health so periodontal evaluation is important to be checked in every appointment. The aim of the present study was to assess gingival health among patients with a fixed orthodontic appliance. A clinical comparative study conducted on 25 patients with an aged ranged from 15 to 25 years. Clinical parameters included plaque index (PI), gingival index (GI), and bleeding on probing (BOP) were recorded at base line before starting orthodontic treatment and after 1 month of treatment. A double paired t-test was applied to the data collected for statistical analysis. The mean value of PI (1.11), GI (1.155), and BOP (0.600) scores was increased after placement of fixed orthodontic appliance, but with no statistically significant difference with base line for PI (P-value = 0.596), GI (P-value = 0.355), and BOP (P-value = 0.256), respectively. Regarding age group, mean PI (1.46), GI (1.22), and BOP (0.875) were increased with increasing age, patients who age’s ≥20 showed statistical significant difference for gingival and plaque means P-value = 0.006 and P-value = 0.03) for ≥20, respectively. The finding of this study had shown that patients with fixed orthodontic appliances had non-significant increase in the mean value of plaque, gingival, and BOP indices scores. All mean scores were increased with increasing age, but with non-significantly for BOP only.
