Swelling of the mandibular alveolar mucosa
2022
Una donna di 30 anni si presenta all’osservazione degli autori presso il Settore di Medicina Orale (Università degli Studi di Palermo) per la comparsa di una neoformazione gengivale a livello del V sestante. In anamnesi patologica remota non risultano patologie sistemiche attuali o pregresse, la paziente è in apparenti buone condizioni di salute, riferisce di non assumere farmaci e non ha subito in passato interventi chirurgici. La paziente, non fumatrice, non riferisce dolore nella sede interessata ma progressivo accrescimento della lesione. All’esame obiettivo extra-orale non si apprezzano linfoadenopatie latero-cervicali o altre anomalie. All’esame obiettivo intra-orale si rileva una neo…
Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Ora…
2021
Background: The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs. Methods: Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities. The PSQI, Epworth Sleepiness Scale (ESS), Hamilton Rating Scales for Depression and Anxiety (HAM-D and HAM-A), Numeric Rating Scale (NRS), and Total Pain Rating Index (T-PRI) were administered. Results: Oral lichen planus pati…
Corticotomy-assisted orthodontics
2011
The use of orthodontic treatment in adult patients is becoming more common and these patients have different requirements specially regarding duration of treatment and facial and dental aesthetics. Alveolar corticotomy is an effective means of accelerating orthodontic treatment. This literature revision include an historical background, biological and orthodontic fundamentals and the most significant clinical applications of this technique. Orthodontic treatment time is reduced with this technique to one-third of that in conventional orthodontics. Alveolar bone grafting of labial and palatal/lingual surfaces ensures root coverage as the dental arch is expanded. Corticotomy-assisted orthodon…
Radiological implications of crestal and subcrestal implant placement in posterior areas. A cone-beam computed tomography study
2020
Background Subcrestal implant placement has been suggested as a method that could contribute to maintain the periimplant soft and hard tissues in comparison with crestal placement. The objective of this study was to investigate the relationship between implant placement at different depths in the alveolar bone and (a) the thickness of the buccal bone plate (BBP); and (b) crestal cortical bone thickness, based on the use of cone-beam computed tomography (CBCT). Material and Methods A cross-sectional study was performed, analyzing CBCT scans from the database of the Oral Surgery Unit of the University of Valencia. Individuals with single missing teeth in posterior sectors were included. Two t…
A skeletal Class III malocclusion with agenesis and canine-bicuspid transposition: a nonsurgical approach
2021
Abstract Background The present case report describes the orthodontic management of a patient who presented with a skeletal Class III malocclusion combined with other dental anomalies. The malocclusion was complicated by agenic maxillary lateral incisors and a lower right second premolar, in company with the transposition of the maxillary canines and premolars. Methods Dentoalveolar compensation of the anteroposterior jaw relationship was performed. The upper deciduous lateral incisors were extracted and the spaces closed, so that the first premolars replaced the missing lateral incisors while the canine transposition was maintained Results Satisfactory results were obtained which provided …
Ein zahngrößen- und gesichtsbreitenbezogener Zahnbogenindex
1994
Taking as its starting point the often postulated criticism of Pont's Index, the intent of the study was to develop a diagnostic procedure which took into consideration the objection that the Pont Index doesn't take the shape of the patient's skull into consideration. On the basis of the data obtained from the models and anthropological measurements of 50 adult subjects with fairly eugnathic dentition, the first step was to follow Pont and study which skull size exhibited the highest correlation to the posterior dental arch. Of all the relevant sizes the zygomatic arch width exhibited the highest correlation. Reference values for the posterior dental arch width, which were obtained with the…
Tierexperimentelle Untersuchungen zur „Erschütterungstheorie“
1983
In einem Tierexperiment an jungen Kaninchen wurde der Einflus von Vibration auf das Knochenwachstum im Bereich des Schadels untersucht. Als Folge der einseitig applizierten mechanischen Schwingungen wurden bei einigen Unterkiefermasen auffallende Seitendifferenze festgestellt. Daruber hinaus konnte eine lokale Knochenvermehrung an den Stellen beobachtet werden, wo der Unterkiefer die vibrierende Unterlage beruhrte.
Digital protocol for creating a virtual gingiva adjacent to teeth with subgingival dental preparations.
2019
Abstract Purpose This article describes a digital technique used to record gingival emergence profiles modeled for the prosthetic restoration of teeth prepared using biologically oriented preparation technique (BOPT). Materials and methods The description of the technique of intraoral recording, manipulation of digital files, and chairside protocol of prosthetic restorations is developed in the present manuscript on two anterior teeth treated with vertical and subgingival dental preparations for restoration with ceramic crowns. The manipulation of the digital files registered with an intraoral scanner with software that allows its alignment (best-fit) and the performance boolean of operatio…
The 100 most-cited articles in orthodontics: A bibliometric study
2018
ABSTRACT Objectives: To identify and analyze the 100 most-cited articles in orthodontics indexed in the Web of Science Category of “Dental, Oral Surgery and Medicine” from 1946 to 2016. Materials and Methods: On hundred articles were identified in a search of the database of the ISI Web of Science and Journal Citation Reports, applying the truncated search term “orthodon*.” Records were manually refined and normalized to unify terms and to remove typographical, transcription, and/or indexing errors. Results: The 100 most-cited articles were published between 1946 and 2012, with numbers of citations ranging from 115 to 881. Of the 251 authors participating, 87.65% published a single work, wh…
Assessment of the stresses produced on the bone implant/tissue interface to the different insertion angulations of the implant - a three-dimensional …
2020
Background The present study aimed to assess the stresses produced on the surface of the bone tissue around dental implants with three different insertion angulations subjected to axial and oblique loading. Material and methods The study was created according to the recommendations of the Checklist for Reporting In-vitro Studies (CRIS). The Straumann™ bone level RC (4.1 x 10 mm) implant, Cone Morse connection (CM), RC Straumann Variobase™ with abutment (3.5 mm) was placed in the region of element 16, with the platform positioned at the height of the bone crest. Three assessment models were produced: model M1 or control - implant perpendicular to the bone crest; model M2 - implant angulated …
