The Effect of Deep Traumatic Overbite on the Periodontium of the Upper Anterior Teeth in a Cohort of Adult Saudi Dental Patients

Aim: to assess the relationship between deep overbite with palatal impingement and periodontal health status in a cohort of adult Saudi dental patients. Materials and Methods:Ten patients (4 males and 6 females, aged 16 to 31 years old) with deep traumatic overbite and palatal impingement were examined. A Hawley retainer appliance with an anterior bite plate was provided for all patients.Pocket depth, bleeding index, gingival index, plaque index and mobility were recorded for four visits after using the appliance with fixed intervals in-between. Repeated measures analysis of variance (ANOVA) was used to assess the differences between visits, control /experimental teeth and surfaces (palatal /labial) for pocket depth, bleeding index, plaque index,gingival index and mobility.

Early intervention of anterior cross bite malocclusion relating to functional class iii malocclusion

This case report describes the treatment of a13-year-old boy with anterior dental cross bite, unilateral cross bite and constricted maxillary arch with removable appliance to bring the teeth into a normal position. A removable acrylic appliance with a bite plate incorporating an expansion screw was used to correct the anterior dental cross bite and align the incisors.

Inferior alveolar nerve damage secondary to orthodontic treatment: A systematic scoping review

BACKGROUND: Neurosensory impairment is a common complication following inferior alveolar nerve (IAN) damage. OBJECTIVE: To document and report the various causes, diagnosis, and management of IAN damage secondary to orthodontic treatment. METHODS: An electronic search for studies that reported IAN damage in patients undergoing orthodontic treatment was performed up to July 15, 2020 using MEDLINE, EMBASE, and PubMed databases. Descriptive analyses and linear regression model were performed. RESULTS: A total of 15 case reports were identified including 16 patients with an overall mean age of 23.3. All the included studies reported temporary sensory alterations which manifested as anesthesia (19%, n = 3), paresthesia (75%, n = 12), or combined (6%, n = 1). The majority of cases managed by stopping the orthodontic force (75%, n = 12), followed by appliance adjustments (19%, n = 3), providing a bite plate (13%, n = 2), and/or providing pharmacological management (38%, n = 6). Full recovery median duration reported in all cases following the aforementioned managements was 17.5 days. CONCLUSIONS: IAN damage secondary to orthodontic treatment is emerging in the literature in recent years. Identifying high risk patients with close proximity to the IAN canal is a must to formulate a proper treatment plan to avoid such complications.

Esthetic Evaluation of Facial Soft Tissue Based on Nonrigid Image Deformation

As the time passes by, orthodontics is paying more and more attention to facial aesthetics. However, related research is mostly in the stage of qualitative evaluation without clinical reference of specific soft tissue data. Therefore, by collecting the pre- and post-treatment photographs of 26 adult female patients, this study used image deformation technology to process the photos of a 23-year-old female patient, and two groups of facial photos were established. Then, 22 males and 27 females were selected to conduct an aesthetic evaluation to the original and processed photos by questionnaire survey. Relevant indicators of the corresponding photos were obtained. Group t-test, paired t-test, and nonparametric test were used in data calculation. For patients with high compliance, deep overbite with low angle or average angle are more suitable for fixed appliance with the bite plate, while with high angle are not suitable. The nonprofessionals prefer narrower face, more retracted lip position, and fuller chin than in the actual treatment. Among them, female evaluators prefer narrower lower face than male evaluators do. Male evaluators prefer thicker lips and chins, especially thicker lower lips than female evaluators do. Laypeople prefer narrower face, more retracted lip position, and fuller chin.

Miniscrews as an alternative for orthopedic traction of the maxilla: A case report

The aim of this study was to report the case of a Class III prepuberal patient treated by a maxillary protraction using four miniscrews. The screws were installed between maxillary first molars and second premolars and between mandibular canines and first premolars. A 1/4˝ intermaxillary elastics were used in both sides, ligating the upper-lower screws to perform a maxillary protraction and correction of the Class III malocclusion. A bite plate made by resin flow was made on lingual surfaces of the mandibular incisors to eliminate occlusal interference. After 16 months of treatment, it was possible to see a significant improvement of patient’s facial profile, with overcorrection in overjet and preservation of the tissues and integrity of dental roots.

Interceptive orthodontic treatment in Singapore: A descriptive study

Background: The benefits of interceptive orthodontic treatment have always been a subject of much debate, and it is understandable that clinicians are confused about how to advise parents of potential interceptive orthodontic patients. Objective: The aim is to study the treatment outcomes of interceptive orthodontics associated with different appliances. Demographic information on patients presenting for interceptive treatment, prevalence and types of dental conditions treated, types and frequency of appliances used, treatment duration and the number of visits taken were also investigated. Methods: This study involved analyzing records of interceptive orthodontic patients seen at the National Dental Centre Singapore from January 2011 to December 2017. Treatment outcomes were divided into success, improvement and failure according to pre-determined treatment objective parameters. Results: A total of 1324 patient records (654 females, 670 males) were studied, with an average age of 10.6±1.9 years. The most common dental condition seen was the anterior crossbite while the most common interceptive orthodontic appliance used was the bite plate. Average treatment duration was 10.8±6.8 months (9.8±9.2 visits) for fixed appliances, 7.5±6.5 months (6.9±3.4 visits) for removable appliances and 10.8±3.2 months (12.6±3.3 visits) for a combination. Interceptive orthodontic treatment had an overall success rate of 75.5%, improvement rate of 9.5% and failure rate of 15.0%. The most common reason for failure was attributed to non-compliance. Conclusion: The data above shed light on interceptive orthodontic treatment in an Asian population and gives useful information for primary care clinicians to provide for concerned parents.

Improved method of complete removable laminar dentures manufacturing for the prosthodontic treatment of patients with completely absent dentition

A device for the formation of a prosthetic plane of the upper jaw check-bite in the course of the prosthodontic treatment of the patients with completely absent dentition was developed in order to improve the formation of the prosthetic plane during complete removable laminar dentures manufacturing. The objective was achieved by the fact that the bite plate of the device was made in the form of U-shaped supporting ruler with a fork-like extension on both sides and with a pocket in the central part. The bite plates for the frontal and chewing parts of the upper jaw check-bite were inserted into the pocket. The bite plates were made removable, the frontal plate was T-shaped, and the chewing one was fork-like with rounded forks. The device was additionally equipped with a movable ruler to record strict parallel alignment in relation to the Camper and inter-pupillary lines. The supporting ruler was equipped with two vertical columns of square shape with symmetric millimeter scales, along which the vertical movements of the movable ruler were conducted and its parallel alignment was recorded in relation to the supporting ruler. The movable ruler was additionally equipped with a leveling device fixed in its central part to position the patient’s head relative to the horizon line. The use of bite plates for the frontal and chewing parts of the upper jaw check-bite and the provision of structural elements in the form of the supporting and movable rulers with the possibility of moving the movable ruler on the vertical columns of the supporting ruler provide a fast, comfortable, precise and uniform formation of the prosthetic plane of the upper jaw check-bite parallel to the Camper and inter-pupillary lines in the prosthodontic treatment of the patients with completely absent dentition.
