Abstract:
Bruxism, a disorder characterized by grinding and clenching of the teeth, directly involves the teeth and masticatory muscles, therefore the trigeminal nerve, whose central nuclei include the Mesencephalic Trigeminal Nucleus (MTN) that is not a true nucleus consisting of the usual multipolar neurons, MTN is the only intraneuraxial ganglion in the central nervous system, composed mainly of large pseudo-unipolar glutamatergic cells, The peripheral branches of the MTN neurons mainly innervate the stretching receptors of the chewing muscles of the jaw and the mechanoreceptors of the periodontal ligament: therefore, they are activated by bruxism. MTN’s central branches release only glutamate (they are only activators cells) and activate the trigeminal motor nucleus and the Reticular Activating System (RAS) nuclei. Bruxism occurs mostly during sleep, so let's see what happens during sleep. To induce and maintain sleep, the hypothalamic neurons of its preoptic area release Gamma-Amino Butyric Acid (GABA), an inhibitor neurotransmitter, on the Reticular Activating System (RAS) nuclei, this neuro-transmitter induces the entry of chlorine into the cells, hyperpolarizing and inhibiting these. MTN cells, on the contrary, are depolarized by GABA, because their receptors are activated upon GABA binding, they "let out" chlorine and depolarize. MTN cells release glutamate, an excitatory neurotransmitter, onto their target cells, in this case onto the RAS cells. During wakefulness, RAS activation causes cerebral cortex activation and also during sleep, of course, the MTN activates the cerebral cortex, furthermore avoids an excessive reduction in RAS neurotransmitters, including noradrenaline, dopamine, serotonin, acetylcholine and glutamate, which, in addition to activating the cerebral cortex, modulate vital functions such as cardiac and respiratory functions. Polysomnography shows that sleep bruxism is always accompanied by cardiac and respiratory activation and, most importantly, by brain function activation. Bruxism is not a para-function, its functions is to activate RAS nuclei, both during wakefulness and during sleep.

James T Craig
Summerbrook Dental Group, United States
Title: Advancements in digital all-on-X surgeries: Improvements to quality, cost and efficiency

Biography:
Craig received a Doctor of Dental Surgery degree from the University of Missouri in 2006. He was on a research team for the National Institutes of Health Department of Dental and Craniofacial Research where he developed novel bone grafting materials and pioneered the use of diatoms to reduce polymerization shrinkage in restorative polymers. He also served as a professor of Histology and Biochemistry for the University of Missouri. As the CEO of BFB Inc., he is an expert speaker on topics of Digital Surgery, bone grafting and head and neck surgical techniques and currently lectures internationally for EnvistaCo
Abstract:
Introduction: Doctors who undergo large All-On-X cases often have to sacrifice one or more of Quality, Cost and Efficiency in treatment outcomes. With the advances in digital surgery however, compromise of this nature can be avoided. Costs can be kept low for the treating doctor, accuracy is improved and the patient can achieve treatment objectives in a very short time with fewer side effects than traditional methods. The purpose of this case study is to describe the experience of performing All-On-X completely digitally and seamlessly.
Methodology: A patient with necrosis of both jaws presents for extraction, debridement of necrotic material, degranulation of infected soft tissue, bone remodeling, bone grafting and bone stabilizer placement for an all-on-6 mandibular and maxillary fixed synthetic prosthetic orthognathic system. Digital tools such as Cone-Beam Computed Tomography, Digital Facebow transfer, Digital 3-D dynamic navigation system, Photogrammetry, Digital prosthetic planning and in-office 3D Printing of the prosthesis were used to achieve a result that took place in just 8 hours, 1 day after meeting the patient for the first time.
Conclusion: Instead of having to wait weeks or even months for more traditional surgical planning using laboratory-fabricated surgical guides, bone foundation guides and analog placement of bone stabilizers, a completely digital workflow enhances Quality, Cost and Efficiency to the practitioner and to the patient, resulting in more desirable treatment outcomes.
Andres Salazar
Pontificla Xaverian University, Colombia
Title: Pfeiffer Syndrome. A middle face distraction treatment by a modified Lefort III technique

Biography:
Andres Salazar is a new maxillofacial surgeon recently graduated from Pontificla Javierian University located in Bogota, Colombia. His principles based on his career are to prevent, diagnose and treat all disease of the maxillofacial complex esqueletal and soft tissues with the unique goal that is to give back quality of life to his patients. This workshop about the Middle Face Distraction has been done when he was a resident of four year guided by their professors Dr. Andres Duque and Dr. Jaime Jimenez who authorized to him to be the speaker of their clinical case done together
Abstract:
Pfeiffer syndrome: Discovered by Arthur Pfeiffer in 1964, with a prevalence of 1:100,000. It is characterized by the clinical presentation of craniosynostosis, hypoplasia of the middle third of the face, syndactyly of the hands and feet. It usually presents with a bilateral coronal synostosis associated with one or more sutures. The dysmorphic skull presents with a transverse magnification greater than anteroposterior, reflecting an enlarged frontal region, depressed midface with a small nose and low nasal bridge with moderate to severe ocular propotosis with the presence of ocular hypertelorism. Cohen classified it in 1993 into 3 types: Type I is a mild skeletal craniofacial disorder with normal neurological development; Type II is a pansynostosis-type craniofacial disorder, with severe proptosis, skeletal abnormalities in stiff fingers and elbows and limited delayed neurological development; Type III is the same as Type II without pansynostosis. Genetics is associated with the FGFR2 gene mutation in 95% of cases and is represented by types II and III, while the FGFR1 gene mutation is found in 5% represented by type I.
The treatment of these patients is the correction of the present signs and symptoms, for which initially the cranial correction of the synostoses is performed by means of cranioplasty at one year of life, followed by distraction or craniofacial advances at 6 to 8 years of life, later management of sequelae in facial projection, especially in nasal management. The emphasis on ocular proptosis is important since surgical treatment is focused on reconstructing the orbital continent.
Treatment is always multidisciplinary, involving neurosurgery, craniomaxillofacial surgery, otorhinolaryngology, oculoplasty, internal medicine.

Dr. Sana Faiq Al-Rubaie, Master degree in Periodontology – Baghdad University, college of Dentistry at 2013. American Academy of Periodontology Member. Founder of Gum Health Clinic – Iraq, Baghdad. E- Instructor, and medical communication skills trainer
Abstract:
Statement of the Problem: Since the evolving understanding of the neurological side effects of SARSCoV-2 infection, Anosmia and Ageusia are affecting 52.73 % of Covid-19 patients during the first 30 days of the disease. Large proportion of them were restored their smell and taste senses partially or completely, however; some patients did not. Efforts are made to discover the best treatment to regenerate the lost sense through topical or systemic application of corticosteroids, Insulin, and others. Hyaluronic acid (HA), the natural glycosaminoglycan, is known of its regulatory role in inflammatory responses, and promotion of regeneration of mineralized and non- mineralized periodontal tissues, and has been used as topical coadjutant treatment in many acute and chronic gingival problems since it showed to have a positive effect on tissue repair and wound healing. The purpose of this case series, show the effect of HA mouth gel preparation on Anosmia and Ageusia. Methodology : 5 cases of complete loss of smell for about 6 months post covid-19 infection , ages range between 38-77 years , were prescribed Hyaluronic acid mouth gel(PerioKIN Hyaluronic 1%) ,as oral home care regimen . Findings: regain of smell and taste after 14 days of using HA as teeth brush twice a day. Conclusion: the anti-inflammatory effect of Hyaluronic acid might be the treatment of choice for Anosmia and Ageusia related to covid-19 infection.

Title: Evaluation of maxillary arch width and palatal volume and depth in patients with maxillary impacted canine by CBCT

Biography:
Soghra Yassaei has expertise in orthodontics and orthopedic treatment. According to her 25 years of clinical experience, she found that in patients with canine impaction who were undergoing orthodontic treatment, some impacted canines erupted spontaneously after palatal expansion without any orthodontic traction. She hypothesized that the volume of the palate of the affected patient is less. The purpose of this study was Evaluation of maxillary arch width and palatal volume and depth in patients with maxillary impacted canine by CBCT. She has an H-index of 10 and co-authored 60 publication(s) receiving 252 citation(s)
Abstract:
Introduction: Canines are the second most common tooth in terms of impaction. Impacted teeth can be associated with some different indices of the dental arch and dentoalveolar structures. The aim of this study was to evaluate maxillary arch width as well as volume and depth of palate in patients with maxillary impacted canine by Cone Beam Computed Tomography (CBCT).
Methods: In this cross-sectional study, 45 CBCT images of patients with unilateral maxillary impacted canines were examined. All patients had palatally impacted canines. Three parameters of maxillary arch width, palatal volume and palatal depth were assessed using axial and sagittal incisions on the CBCT images. Then all the measurements on the impacted side were compared with the non-impacted side. Data were entered into SPSS software and paired sample t-test and Student's t-test were used for comparison. The significance level of 0.05 was considered.
Results: The maxillary arch width on the impacted side was significantly less than the normal side (P<0.001). The mean depth of the palate was 14.86 ± 3.53 mm. There was a significant correlation between canine impaction and Palatal volume (R=0.728 and P-value<0.001), but no significant correlation between canine impaction and Maxillary arch width was shown (R=0.15 and p-value=0.326).
Conclusion: The impacted canine was significantly associated with a reduction in the width of the maxillary arch on the affected side and it made no difference if the impacted side was left or right. Also, impacted canine teeth were significantly associated with volume reduction on the affected side

Abstract:
Miniscrews can be useful in many ways for orthodontic treatment procedures and biomechanical movements. Intrusion, retraction of anterior teeth, distalization or mesialisation and can be used either with fixed appliance or aligners.
Introduction: Today, Orthodontic anchorage is one of the most important factor for orthodontic treatment to be successful and conventional orthodontic appliances like headgear and intra-oral elastics are usually used but nowadays mini implants are being utilized as skeletal anchorage devices instead of conventional orthodontic appliances.
According to recent studies relatively higher numbers of patients are choosing miniscrews over extraction of teeth although very few had previous knowledge of mini-implants. Moreover, safety procedures of positioning them using 3D technology emerging makes it easier for both patients and practitioners.
Learning objectives: The objectives should be specific and measurable, behavioral verbs are to be utilized. General verbs as: “understand, appreciate, know, become, learn” should not be used.

Abstract:
Every patient deserves to understand their oral condition and has the information on how to best achieve their oral health and aesthetic goals for a healthy smile; this could be achieved by establishing normal oral rest posture. Their primary focus add to teeth is how occlusion “static and dynamic”, Jaws, soft tissues behave and head positioned. The human body is a complex organism made up of many overlapping systems. When one of those systems has a defect, pain and abnormalities can affect other bodily systems and make life more of a challenge. Every dentist has to be involved in screen for sleep disorder breathing as a comprehensive medical and dental history to recognize symptoms such as sleepiness, choking, snoring or witnessed apnea and an evaluation of risk factors such as obesity, craniofacial dystrophy, or hypertension. Now we all really looking into mouth of countless individual number with airway problems but crosses undiagnosed. We organized will on compressive examination of dentition caries, wear, gingiva, etc. However, we should look deeper to another thing that is one of the controlling factor of dental health and possibly life threatening. On checking, the airway we should gate rid of one of the false questions “are you a mouth breather”. To help establishing oral and possibly general body health we should look for Normal physiologic breathing and normal oral rest posture. This could be achieved by bringing the teeth and the lips together, elevate the tongue to rest in the palate and initiate the nasal breath.
