AI Article Synopsis
- Deep overbite is a prevalent malocclusion that is challenging to treat and maintain over the long term, necessitating an update to existing literature on the subject.
- A systematic review of research indicated that the average relapse rate for deep overbite correction is 47.27%, with variability based on treatment type and age at treatment initiation.
- Factors such as the orthodontic method used and the age of patients at the start of treatment significantly influence the stability of deep overbite corrections.
Article Abstract
Introduction: Deep overbite is one of the most common malocclusions and is the most difficult to treat successfully. The real challenge remains the stability of long-term deep overbite correction. A search through the scientific literature revealed only one systematic review on this subject. Given the recent publications on the stability of deep bite correction and the development of new processes designed to avoid relapse of these treatments, this one existing systematic review needs to be updated. The purpose of the present systematic review is to evaluate the long-term stability of deep overbite correction.
Materials And Methods: Electronic databases were searched and nonelectronic journals were manually explored for papers on long-term stability and relapse of deep overbite correction. Articles deemed appropriate for inclusion in this review were selected and analyzed. Their scientific quality was assessed and the data they contained were extracted and summarized.
Results: The rate of deep overbite relapse was 47.27%. Patients treated with the straight wire appliance showed a 67.74% relapse rate whereas those treated with the Ricketts biological progressive segmented mechanics appliance displayed a 30.38% rate. Subjects treated towards the end of adolescence presented a 14.3% rate of deep overbite relapse whereas those treated in their early teens or in adulthood had a deep overbite relapse rate of 30% and 30.8%, respectively. Intramuscular injections of botox helped obtain 100% stability in maxillofacial surgery to correct deep bite.
Conclusion: Age at initiation of treatment and treatment technique are two factors impacting the long-term stability of deep overbite correction.

Dental arch dimensional changes in deep bite adults treated with orthodontic fixed appliances in conjunction with maxillary incisor vs. canine bite turbos during the levelling and aligning phase: a randomized clinical trial.

Introduction: This randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT).
Materials And Methods: Forty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T) to 3 months after aligning with 0.

This case report details the treatment of a 23-year-old female patient with Class II division 2 malocclusion with a Class II skeletal base due to a retrognathic mandible. The condition was further complicated by a complete overbite, absence of tooth #36, and a gummy smile. The Forsus appliance has shown to be effective in correcting Class II malocclusion in adult patients, with significant improvements in bite and facial esthetics.

Background: Molariform second premolar is a rare dental anomaly where the second premolar resembles a molar in size and shape. This condition is often linked to macrodontia, a rare enlargement of teeth that disrupts dental proportions and can manifest in isolated, relative, or generalized forms. Although mandibular second premolars are more prone to morphological variability, the occurrence of bilateral molariform premolars, induced by a unique form of gemination, is exceptionally uncommon and infrequently documented, thus making this case clinically significant.

Background: Anterior disc displacement (ADD) is the most common type of temporomandibular joint (TMJ) internal derangement and may lead to condylar resorption (CR) during the adolescence period, but the specific malocclusion associated with ADD and CR remains unclear.
Objective: This study aimed to investigate the malocclusion associated with TMJ ADD and CR in adolescents.
Methods: This cross-sectional study included a clinical examination of adolescent patients aged 11-19 years.

Purpose: To investigate the functional and structural characteristics of temporomandibular joint(TMJ) in introverted deep overbite patients with severe wear, to analyze the correlation between the vertical distance of the lower 1/3 of the face and TMJ space, and to compare the clinical efficacy of multidisciplinary treatment with orthodontics and prosthodontics on TMJ function.
Methods: Eighty patients with deep overbite and severe abrasion and forty subjects with normal occlusion admitted to our hospital from January 2019 to June 2023 were enrolled in this study. The clinical data were collected and the functional and structural characteristics of TMJ were collected.
