Gummy Smiles: Etiologies, Diagnoses & Formulating a Clinically Effective Treatment Protocol
The phenomenon of a gummy smile, characterized by an excessive display of gingival tissue during smiling, is primarily a subjective clinical observation rather than a quantifiable cephalometric measurement. The variability in underlying causes, ranging from soft tissue to hard tissue origins, necessitates a nuanced approach for diagnosis and treatment. This communication offers a comprehensive overview of the multifaceted etiology of gummy smiles, highlighting the importance of distinguishing between soft and hard tissue origins.

“Piezocision assisted Orthodontics: Already 14 years…”
Piezocision ™ assisted orthodontics as a technique was first published 14 years ago. This technique has evolved into a treatment concept that allows the orthodontist to treat successfully challenging cases by creating differential anchorage in three planes while maintaining or enhancing the patients’ period ontal phenotype. Technical advances in digital dentistry over the past 10 years have brought some important innovations to Piezocision™ assisted orthodontic surgery. Dynamic Navigated Piezocision™ allows the surgeon to see the corticotomies in REAL TIME on the monitor screen, thus avoiding roots , anatomical str...

TMD diagnosis –What should general dentists and orthodontists know?
This article will consider potential reasons for this and outline the importance of diagnosis for both individuals living with the condition and clinicians. We will suggest utilisation of a pragmatic, evidence based, broad group diagnosis using simplified examination procedures and diagnostic aids to support the TMD diagnostic process for clinicians.

Effect of orthodontic appliances on masticatory muscle activity
There is limited and conflicting evidence regarding the impact of orthodontic appliances on masticatory muscle activity (MMA), jaw function, and oral parafunctional behaviours. Investigations in this field frequently utilise surface electromyography (sEMG) to analyse changes in muscle contractile activity. Fixed orthodontics appliances have been associated with significant reductions in MMA post archwire activation. Conversely, elevations in masseter and digastric muscle activity have been reported in response to removable functional appliances. (Source: Seminars in Orthodontics)

Occlusal dysesthesia and its impact on daily practice
In 1976, Marbach first described in the literature a clinical entity that he called “the phantom bite,” now known as “occlusal dysesthesia” (OD). Most patients suffering from OD are going through an unusually stressful period in their lives and have undergone dental therapy at the same time, resulting in a mental fixation on their teeth. They perceive clinically unremarkabl e occlusal contacts as bothersome or uncomfortable and TMD is a common comorbidity. Although there is no apparent relationship between the clinical findings and the nature and severity of the reported occlusal complaints, patients search for the...

Reliability Statistics Every Orthodontist Should Know
It is essential to conduct a reliability examination even if the method was considered reliable in the past, as it may not be reliable in a new study conducted by different researchers using different materials. The current article highlights the importance of reliability examination in orthodontic studies and explains which assessment methods are more appropriate than others. Several fallacies in reporting and interpreting reliability are also discussed. In addition, the article presents examples of reliability examination for one-, two-, and three-dimensional data using graphic visualization in a tutorial format. (Source...

A three-dimensional perspective on Brodie Bite's diagnosis, planning, treatment alternatives, and complications
This narrative review describes the different diagnostic, prognostic, and management aspects of the Brodie Bite. A current literature review was completed to identify relevant case reports, case series, and reviews about the Brodie Bite. Brodie Bite cases, fortunately, are not frequent. A checklist for this malocclusion is presented. Additionally, a description of the advantages of an early diagnosis will be discussed to avoid its progression to a more complex clinical scenario. The importance of solving the Brodie Bite before correcting any other simultaneous malocclusion problem is stressed. (Source: Seminars in Orthodontics)

Influence of guided insertion on the success of paramedian palatal miniscrews
To evaluate the influence of guided insertion on the success of paramedian palatal miniscrews the treatment of 103 patients was evaluated. The patients were divided into two groups. The miniscrews of group A (65 patients, 130 miniscrews; conventional insertion) showed a success rate of 97.69%, those of group B (38 patients, 76 miniscrews; guided insertion) a success rate of 97.37 %). The differences were not statistically significant. Guided insertion of miniscrews did not lead to a higher success rate compared to conventional freehand insertion when inserting in the paramedian part of the T-zone.

Orthodontic tooth movement through regenerative sites: A 25-year systematic review
This systematic review aimed to investigate the efficacy of orthodontic tooth movement (OTM) through bone regenerated with osteoconductive grafts, together with the risk of root resorption (RR), in relation to the material and the timing of force initiation. Following PRISMA-ScR guidelines, three major electronic databases were searched (PubMed, EMBASE, and Cochrane). Only studies which reported on the primary outcome (OTM rate) were included. Investigations with fewer than 3 participants/groups and an absence of controls were excluded. (Source: Seminars in Orthodontics)

Orthodontic space closure after loss of maxillary incisors and periodontal breakdown of the edentulous area and on adjacent teeth.
The closure of an edentulous space with the orthodontic movement of adjacent teeth even if affected by severe loss of periodontal support is a treatment option nowadays supplanted by the implant-born crown substitution and periodontal regenerative/reconstructive therapy. Nevertheless it is important not to forget some fundamentals of dental research that still justify, even more when combined with the most recent innovations in the field of mucogingival surgery and guided tissue regeneration, the alternative of orthodontic space closure.

Enamel interproximal reduction and periodontal health
Enamel Interproximal Reduction (IPR), also known as stripping, is an orthodontic procedure used by many clinicians, especially in non-extraction cases. It aims to reduce the mesiodistal diameter of teeth by removing interproximal enamel. This therapeutic option allows to obtain space in the dental arch to achieve tooth alignment, in case of mild or moderate crowding, and to preserve the papilla avoiding the onset of black triangles. IPR is an irreversible procedure, and it requires an accurate case examination to avoid damage, such as demineralization of the enamel or periodontal complications, that can compromise both aes...

Temporomandibular disorders: Definition and Etiology
Temporomandibular disorders (TMDs) are a group of musculoskeletal conditions affecting the masticatory system and which are best defined based on symptoms and signs reflective of the underlying disease process. Etiology – the cause of disease – is best considered as risk determinants due to the complexity of TMDs in terms of the broad range of factors that place an individual at risk for initial development of a TMD and at risk for transition from an acute disorder to a chronic disorder. Identified risk determi nants act together in unique patterns across individuals; notably, painful TMDs seldom occur in isolation of ...

Bruxism: an orthodontist's perspective
The aim of the present manuscript is to give a narrative overview for clinicians summarizing the knowledge concerning a phenomenon that they may frequently come across in both children and adults: sleep (SB) and awake (AB) bruxism. Indeed, prevalence rates in adults range from 8% to 16% for SB and 22% to 30% for AB, whilst in children they raise up to 40%.The complex relationship between bruxism, the most common underlying primary and/or comorbid conditions, and the potential clinical consequences for both AB and SB in children and adults will be considered.
