TECNICHE CHIRURGICHE DI ANCORAGGIO TEMPORANEO, SURGICAL TECNIQUE OF TEMPORARY ANCHORAGE DEVICES
No full textLa ricerca nel campo della medicina rende giorno dopo giorno passi importanti verso nuove frontiere. In odontoiatria, molti progressi sono stati compiuti negli ultimi decenni, in medici infatti spinti dalla necessità di realizzare le terapie che erano sempre più avanzati, valido ed affidabile nel tempo hanno adottato tecniche per tener conto delle numerose ed elevate esigenze del paziente, come ad come importanti aspettative estetiche, il comfort durante la terapia (per non sottovalutare l'aspetto psicologico dei pazienti che possono influenzare le relazioni sociali nella loro quotidiana).
La domanda di trattamento ortodontico da parte degli adulti è aumentata negli ultimi anni. La popolazione adulta presenta spesso la riduzione dei parodontale di supporto del tessuto e diversi obiettivi di trattamento rispetto alla popolazione pediatrica e adolescenziale.
Il compromesso biomeccanico per poter rispondere più semplicemente a questa doppia componente è l'uso di dispositivi di ancoraggio semplici ed efficaci: i TADS (dall'inglese temporanee ancoraggio Devices).
Il tema è l'uso e le tecniche chirurgiche per l'inserimento di dispositivi di ancoraggio temporanei, definiti da TADS acronimo.
In questo contesto, con metodi diagnostici tradizionali e digitali e utilizzando materiali, strumenti e tecniche standardizzate è cresciuta notevolmente la prevedibilità della terapia stessa.
I vantaggi di questo nuovo dispositivo sono la minore richiesta di collaborazione da parte del paziente, con una notevole riduzione della necessità di ancoraggio dentale e riduzione dei tempi di lavorazione.
Grazie a tali dispositivi medico-chirurgici, il dentista è in grado di offrire al tempo stesso un trattamento soddisfacente e di alta qualità per il paziente.
L'uso e l'applicazione dei TADS è parte di un contesto multidisciplinare che coinvolge più professionisti appartenenti a diversi rami dentali. L'insieme dei dispositivi di ancoraggio temporanei include gli impianti osteointegrati, le piastre di mini-ancoraggio e mini-viti.
Questo documento illustra le tecniche chirurgiche di inserimento di mini-viti.Research in the field of medicine makes day after day important steps toward new frontiers. In dentistry, much progress has been achieved in recent decades, in fact clinicians driven by the need to realize the therapies that were more and more advanced, valid and reliable over time have adopted techniques to take into account the numerous and high patient needs , such as important aesthetic expectations, comfort during therapy (not to underestimate the psychological aspect of patients that may affect social relationships in their daily).
The demand for orthodontic treatment by adults has increased in recent years. The adult population often presents reduction of periodontal supporting tissue and different treatment goals compared to the pediatric and adolescent population.
The biomechanical compromise to be able to respond more simply to this twofold component is the use of simple and effective anchoring devices: the TADS (from English Temporary Anchorage Devices).
The topic is the use and surgical techniques for inserting temporary anchorage devices, defined by TADS acronym.
In this context, using traditional and digital diagnostic methods and using materials, tools and standardized techniques has grown considerably the predictability of the therapy itself.
The advantages of this new device are the smaller demand for collaboration by the patient, with a remarkable reduction of the need for dental anchor and reduction of processing times.
Thanks to such medical-surgical devices, the dentist is able to offer at the same time a satisfactory treatment and high quality for the patient.
The use and application of the TADS is part of a multidisciplinary context involving more professionals belonging to different dental branches. The set of temporary anchorage devices includes the osseointegrated implants, the mini-anchor plates and mini-screws.
This paper will discuss the surgical techniques of insertion of mini-screws
Conservative therapy of non carious cervical lesion (NCCL): original method
No full textAIM: The process of twisting has been used for decades to fabricate stainless steel instruments, but it was previously thought to be an impractical method for nickel-titanium (Ni-Ti) instrument manufacture A manufacturing method of twisting Nickel-Titanium wire to produce Ni-Ti files has been recently developed: the twisted files (TF). Theoretically, this new manufacturing process should overcome the problems associated with a grinding process, which previously limited instrument strength. Since TF manufacturing process is new and different from grinding, the aim of the present study was to evaluate the effects of a final deoxidation process (Deox) on torsional resistance of TF instruments. METHODS: Testing was performed in accordance with the International Standard (ISO 3630-1) by comparing 20 TF instruments versus 20 TF prototype instruments produced without the final deoxidation process. Data were collected and statistically analyzed (t-test). RESULTS: Results show that TF instruments withstood 90% more torque (max. torque) than TF prototype instruments manufactured without the deoxidation process (88.7 vs. 53.3 g/cm). This difference was found to be statistically significant at the 0.05 level of significance. CONCLUSION: Since design and dimensions of tested instruments were the same, the deoxidation process could be the only explanation of the improvement in torsional resistance
Enucleazione di un adenoma pleomorfo del palato. Una scelta conservativa. Enucleation of a pleomorphic adenoma of the palate: a conservative choice
No full textThe benign mixed tumor (pleomorphic adenoma) is the most common intraoral salivary gland tumor: more than 50% occurs on the hard and soft palate. The epidemiological data, histopathological and clinical features, preoperative diagnostic methodologies, treatment options, recurrence rates and prediction published in the literature for this neoplasm are discussed. A case of minor salivary gland tumor of the palate in a 26 year old man is reported. The therapy chosen was a surgical conservative enucleation of the lesion. Histological examination showed pleomorphic adenoma; there is no recurrence after 2 years
