Title: Aesthetic driven orthodontics with the Pitts Protocols

Abstract:

He will talk about the paradigm shift with the Pitts Protocols in other words how we can change our orthodontic methods to achieve greater results with aesthetic driven treatment planning and how we can accomplish perfect aesthetics with great function. The Pitts Protocols include the super precise Pitts21 bracket system, the Smile Arc Protection (SAP) bracket positioning, early torque control, the use of disarticulation and early light elastics with a simplified archwire sequence.  With the Pitts Active early concept we can reduce the treatment time by engaging and activating the appliance as early as possible and the expansion with light forces helps for non-extraction treatment to be able to create the “12 tooth smile”. You will see how we can use Digital Smile Design, tooth recontouring, interproximal reduction and laser gingiva contouring for superior esthetic results. Case Studies will demonstrate how is it possible to simplify and shorten the treatment time of the various malocclusions and how to turn extraction cases into non-extraction and surgical cases into non-surgical solution with beautiful aesthetic results.

Title: POWDER technology and more POWER in the dental prevention

Abstract:

Disease prevention and maintenance of good oral health is key to success of in-clinic dental treatments for dental professionals and a healthy, happy life for patients, besides helping reduce pain and expense, more often encountered when the oral hygiene is poor. Preventive dental measures, known as oral prophylaxis are offered by dental professionals and extend to measures that patients take at home to ensure effective and long-term oral hygiene. Professional care offers deep teeth cleaning at the dental office whereas home care by individuals helps prolong its benefits. 

Effective removal of biofilm, the causative reason for dental diseases like gingivitis, periodontitis or tooth decay is essential for good oral health. Years of research and technological advancement has culminated into a clinical method for modern day clinical prophylaxis called "Guided Biofilm Therapy" (GBT). This state-of-the-art treatment protocol consists of eight clearly defined steps and has truly revolutionized the treatment of dental diseases and professional teeth cleaning. The paradigm change is achieved primarily from the more intensive use of powder jet technology which allows teeth to be cleaned in a comfortable, gentle, time efficient, and effective manner.  

Powder technology offers a broad opportunity to professional prophylaxis thanks to the "multi-mini" impact working mechanism. This mechanism combines a minimally invasive cleaning procedure due to the small particle impact with a highly efficient procedure given the quantity of particles reaching the surface. The powder itself is very versatile and has a range of 10 different application opportunities. The smart delivery pathway of the from the powder chamber up to the tooth surface can be optimized to ensure the best treatment comfort for both the patient and the practitioner.  

This presentation will immerse you in the POWER of the POWDER in PROFESSIONAL PROPHYLAXIS.

Title: Case Report : Pansinusitis and periorbital cellulitis complicating External sinus lifting procedures

Abstract:

Perforation of the maxillary sinus membrane is a common complication during sinus lifting procedures(10-40%).Maxillary sinusitis might result and displacement of the graft material may be a contributing factor. Antibiotic Regimes with removal of the implants perforating the sinus have been used for management of sinusitis with immediate or late replacement of the dental implants .

Patient with recurrent severe maxillary,ethmoid and frontal sinusitis attended our center complaining from periorbiral cellulitis .She visited multiple ENT clinics for several months with limited improvement and recurrence of the infection.CT scan revealed titanium membrane displacement into the maxillary sinus. Drainage was done intraorally and removal of the titanium membrane. She had sinus lifting procedure right side 9 years ago for placement of 3 implants to replace upper posterior teeth. Patient insisted not to remove the implants and accepted treatment without warrranty of the result. Sinus membrane was elevared and PRF used to fill the space above the implant apices. The infection resolved completely within 10 days. Follow up of the patient for more than 40 months did not show any recurrence . CT Scan shows formation of bony partition between the implants and the maxillary sinus.

Title: Innovative Artificial Intelligence-Based Algorithm for an Accurate Tooth Prognosis Decision

Abstract:

Appropriate comprehensive treatment planning with a multidisciplinary approach is essential in clinical dentistry. It requires the evaluation of the entire oral health conditions, including the occlusal scheme, arch forms, and more. Furthermore, an accurate evaluation of the prognosis of each tooth is a critical initial step for treatment planning. Artificial Intelligence (AI) has been used in dentistry to make the diagnosis process more accurate and efficient in various disciplines however, to date, little is known about AI-implemented tooth prognosis decisions in consideration of comprehensive treatment planning.
Our recent publication assessed efficacy of an AI-based machine-learning algorithm for tooth prognosis decisions. Seventeen clinical determining parameters were established by 20 faculty from multiple disciplines. The learning data used 94 cases with 2359 teeth, and 16 evaluators individually assessed the tooth prognosis by ranking from 1 to 5, with 1: hopeless tooth (signifying severe problems requiring tooth extraction) and 5: healthy tooth (signifying good conditions for long-term). The algorism was then created by 3 methods, including gradient boosting classifier, decision tree classifier, and random forest classifier. These three methods were evaluated against the gold standard data determined by the consensus of three experienced prosthodontists, and the decision tree classifier had the best accuracy (0.8413) among the three methods. For the next steps, we further investigated the efficiency of the recently created algorism for the larger number of cases with the wider range of case complexity.
In this presentation, decision of tooth prognosis for complex cases determined by AI-based algorithm will be introduced. Furthermore, comparison of tooth prognosis decision among the countries with different insurance system will be provided.

Title: Deformation behavior and biomechanical properties of enamel and dentine about a white spot lesion

Abstract:

Statement of the Problem: The appearance of acids in the oral cavity may occur during the consumption of a number of foods and beverages, and also as a result of the vital activity of cariogenic bacteria, which contributes to the demineralization process - partial dissolution of the main structural elements of enamel - hydroxyapatite crystallites. Early caries is characterized by the process of demineralization of tooth enamel without cavitation under a relatively intact tissue surface. In this case, pores appear in the subsurface region. Due to the significant difference in the refractive indices of the medium within the porous area and the sound tissues surrounding it, a whitish opaque region appearance of demineralized pathologically altered enamel lesions can be observed. This phenomenon is called white spot lesion (WSL). Overall, the number of studies characterizing the fundamental changes that emerge in natural WSLs from materials, microstructural and biomechanical point of view remains rather low. Methodology & Theoretical Orientation: The present work aims to characterize the complex of properties (mineral density, reduced Young’s modulus, indentation hardness, average roughness, maximum height of roughness) and features (surface structure, molecular composition, indentation creep) of the enamel and dentine about a WSL on a single tooth using computed X-ray microtomography, bitewing X-ray, nanoindentation, Raman spectroscopy, scanning electron (Figure 1), atomic force and optical microscopy. The aim of obtaining such information is to provide the basis for future studies of efficacy of minimal invasive treatments of caries and deeper analysis of these properties and features. Conclusion & Significance: The work reveals some fundamental changes emerging inside human enamel and dentine at the first clinically visible stage of the carious disease from several points of view. The complex of characteristics was found for the natural enamel WSL and dentine bordering it. The properties obtained were compared to those of sound counterparts of the aforementioned areas on the same tooth. The significant reduction of the mechanical properties was recorded for both carious areas accompanied by the abnormality of the unloading response and change of the character of indentation marks caused by mineral loss. Increase of indentation creep for WSL area was recorded. The maps of mechanical properties show that the enamel outside the WSL is weakened despite its appearance as being sound on optical and bitewing X-ray images. At the same time, the decrease in mineral density of the WSL area and bordering dentine was rather small. The average roughness of polished surfaces was considerably increased in the caries-affected areas caused by the demineralization process, and the surface relief changed as well. Raman spectroscopy research resulted in detection of interesting repeatable features connected to changes in the molecular composition in the carious areas. This research was funded by the Russian Science Foundation, grant number 19-19-00444.

Title: Methods of Anterior Torque Control during Retraction: A Systematic Review

Abstract:

Background: There are various methods of controlling the inclination of the incisors during retraction, but there is no evidence as to the advantages of some methods over others. Research conducted by our team related to the review of the available literature identified several methods with  varied effectiveness of torque control during anterior teeth retraction.

Methods: In the study of the available literature that was qualified to our study we included the patients with complete permanent dentition with the examined the maxillary incisor torque after  and before retraction with straight-wire appliance and different modes of torque control where statistically significant differences in torque values of the upper incisors after orthodontic treatment were observed. The literature of our research were subjected to risk of bias and quality analyses with the ROBINS-I protocol and the modified Newcastle–Ottawa QAS, respectively

Results: Despite numerous articles published in reputable scientific journals (580 subjects) only 13 articles could be selected because only they met our criteria. All authors recognized that incisors were retroclined during retraction by 2.46° (mean difference), which was statistically significant. Statistical analysis confirmed that the differences in torque between the study group and the control group were statistically significant in most of research. We assessed our research for heterogeneity of articles in relation to their impact on the significance of the analysis performed.

Conclusion: As a result of the analysis conducted by our team we recognized that both properly performed corticotomy and en-masse retraction using orthodontic microimplants seem to be the most effective and scientifically validated methods of torque control. Just after the publication of our research an article “En-Mass Retraction of Maxillary Anterior Teeth with Severe Proclination and Root Resorption—A Case Report” appeared  which also discussed the advanced retraction of incisors with the use of Tads and evaluate the difference in their inclination.

Title: Current Approach for the Management of Osteoradionecrosis with Pentoxifylline and Tocopherol

Abstract:

Osteoradionecrosis (ORN) is a devastating complication of radiotherapy, and outcomes in alteration of the appearance and function of the oral cavity and jaw that creates substantial deterioration in patient quality of life. Osteoradionecrosis can be spontaneous but primarily related to hypovascular, hypocellular, and hypoxic conditions that exist in bone. Mandibular ORN is more common when compared to maxilla. ORN incidence ranges from 2% to 22% and, in the 70% of cases, ORN occur within 3 years after radiation therapy. Several factors in the literature are interrelated with the risk of developing ORN. These include total radiation dose, dental extractions, poor oral hygiene, tobacco, alcohol use, tumor size, location and staging. In addition to antibiotics, treatment options for osteoradionecrosis includes surgical approaches, hyperbaric oxygen therapy, and combined therapy with pentoxifylline and tocopherol, among this combined therapy with pentoxifylline and tocopherol have been newly introduced. The combined use of pentoxifylline with tocopherol (vitamin E) has been justified by a synergistic antioxidant effect. These are easily available and safe drugs. Researches have shown that this combination noticeably minimizes the chronic damages of radiation therapy. Therefore, the purpose of this paper is to discuss the definition and classifications of ORN, its pathogenesis and risk Factors, previous management options, basic information on pentoxifylline and tocopherol and current reports of pentoxifylline and tocopherol combined therapy.
