Bruxism: an orthodontist's perspective
Full text linkThe 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.
In addition, in view of the fact that over the last few decades the demand for orthodontic treatment at all ages has increased, the correlation between bruxism-related masseter muscle activity (MMA) and the use of orthodontic appliances (i.e., fixed appliances and clear aligners) is also discussed, along with the proposal of some clinical recommendations
Correlazioni estetiche dento-labiali nel restauro anteriore: presentazione di un caso clinico. Dental-labial esthetics correlations in maxillary teeth restorations. A case report.
No full textBACKGROUND The relationship of the labial soft tissues to the permanent maxillary teeth is well
known in aesthetic dentistry. In addition to framing the smile and establishing the minimum areas in
need of esthetic enhancement, the lips shade also reveal the correct morphology and position of the
teeth. In esthetic restorative dentistry, the ultimate option for esthetic smile rehabilitation has
become porcelain veneers. Porcelain laminate veneers redefined conservative cosmetic dental
treatment. With a clear consensus, porcelain veneers now are evolving into more functionally and
esthetically dynamic restorations. However, the dentist should complete a facial and dental analysis.
The esthetic analysis should include an evaluation of the patient’s requests and expectations, and an
assessment of the following oral features: dental midline, facial profile, lip thickness, tooth exposure
at rest, incisal curvature, buccal corridor, tooth shape and texture, incisal edge position, individual
tooth proportions and contours, occlusal relationship, tooth axis and tooth arrangement. The
incorporation of these principles is illustrated in the following case presentation. METHODS AND
MATERIAL Case Description. A 40-year-old woman with a VI class composite restoration on
the surface of a maxillary incisor sought treatment for esthetic improvement of her smile. It was
evaluated the patient’s goals, midline position and cant, lip position and fullness, color, incisal edge
position, desired tooth contours and occlusion. Once it was determined the ideal final position and
shape of the tooth, it was decided that the patient was a candidate for a porcelain veneer. RESULTS
Porcelain veneer improved the final smile. A proportionate in anterior tooth shape was achieved
with enhancement of the esthetic of the lips. CONCLUSION To optimize the outcome, dentists
should perform a complete esthetic examination before selecting and planning treatment for patients
receiving aesthetic correction of the smile
Orthodontic emergencies and perspectives during and after the COVID-19 pandemic: The italian experience
No full textObjective: To investigate the types of dental emergencies that occurred during the lockdown period in Italy (12th March—4th May) and to investigate future therapeutic preferences related to the use of different types of appliances. Material and Methods: A questionnaire dedicated to assessing dental emergencies during the lockdown period and surveying the resumption of orthodontic practice was submitted to clinicians in digital form. The first part of the questionnaire, focused on the orthodontic emergencies that were encountered in relation to the different types of orthodontic appliances and how these were resolved. The second part of the questionnaire was devoted to the resumption of clinical practice; in particular, it was designed to assess whether and what percentage of clinicians are willing to change the duration of appointments in relation to the different types of appliance used, asking them whether their approach to orthodontic treatment would change in the coming months as compared to the pre-COVID-19 era. Results: Results show that in most cases (82%), the percentage of patients who experienced a dental emergency was less than 5% and that far fewer emergencies were attributable to removable (5.7%) than to fixed appliances (94.3%). Looking ahead, clinicians expressed a greater preference for using removable (60.8%) rather than fixed appliances (39.2%). Conclusion: During the lockdown, there relatively few orthodontic emergencies, many of which were handled by telephone consultation. However, a far lower percentage of emergencies were generated by removable (e.g., clear aligners) as opposed to fixed appliances (e.g., multibracket equipment), likely influencing the decision of the majority of clinicians to opt for removable appliances in the wake of the COVID-19 pandemic
Aligner hybrid orthodontic approach to treat severe transverse divergence in an adolescent girl: A case report

Invisible treatment with lingual appliance for the correction of an adult class II subdivision with asymmetrical Wilson and Spee curves: A case report
No full textThis article describes a class II subdivision malocclusion successfully treated by an invisible lingual appliance. The combination of en-masse distalization by interradicular palatal mini-screws and inner unilateral class II auxiliaries, first by intermaxillary elastic, later by a class II coil spring, resulted in a dento-alveolar correction, allowing one to maintain the appliance completely invisible. At the same time, the inclination of buccal sectors was normalized by a correct torque expression with set-up overcorrections, resulting in a significant improvement of the buccal corridors. This case report demonstrates the possibility of successfully solving class II division 2 subdivision malocclusion in adult patients without surgery by means of a completely invisible appliance. It also demonstrates that correct levelling and torque expression, for the correction of asymmetrical Spee and Wilson curves, are achievable with an accurate set-up planning. On the other hand, it underlines the necessity of mini-screws, auxiliaries and set-up overcorrections in order to obtain the best results
Non-surgical occlusal plane cant resolution with lingual straight-wire appliance and miniscrews in a class II asymmetric adult patient
No full textThis case report describes a complex class II case with important maxillo-mandibular asymmetry in an adult patient treated with lingual straight-wire appliance. With the twofold aim of obtaining dramatic aesthetic improvement, since the patient refused surgical option, and ideal occlusal relationship, accurate set-up planification and biomechanical strategies with TADS for occlusal plane cant correction are needed to achieve the planned results. This case report demonstrates the possibility of solving successfully class II malocclusion with significant asymmetry in adult patient without surgery by means of an aesthetic appliance; on the other hand, it underlines the necessity of miniscrews and auxiliaries in order to obtain the best results

aligners have significant biomechanical limitations.6 Rotation of conical teeth (premolars and canines) is among the most difficult tooth movements to achieve,7,8 along with movements that involve root control.9,10 In addition, aligners are less reliable in the vertical plane, especially in cases requiring significant extrusion or intrusion.11 On the other hand, various authors agree that aligners are particularly effective in achieving buccal or lingual tipping movements
Non-compliance treatment in a young adult full-step class II division 2 malocclusion with preadjusted lingual appliance and upper first molars extractions
No full textThis case report describes a complex full-step class II case in a young adult patient treated with lingual straight-wire appliance and upper first molar extraction. As the patient refused a surgical treatment, she was offered the best possible camouflage with the double aim of obtaining an ideal occlusal relationship and maintaining the profile; appropriate biomechanical strategies, including extraction choice and anchorage control during space closure, were needed to achieve the planned results. This case report demonstrates the possibility of successfully resolving severe sagittal discrepancies in an adult patient without surgical treatment by means of a completely invisible non-compliance technique, with the extraction of the most compromised teeth. This report also underlines the need for careful planning during both diagnostic and treatment phases, in order to obtain the best results
