Biography:
Ali Nankali is a Clinical Senior Lecturer at Teaching and Innovation Centre of the Barts and the London Medical and Dental School. In 1998, he took a keen interest in Restorative Dentistry which led him to commence his extensive research on application of post and cores. Following his research, he proposed a number of novel inventions such as Nankali Post System, Nankali bur and Masticatory Force classification. He was awarded his PhD in 2004 by National Medical University in Kiev/Ukraine where he registered as a specialist in Prosthodontics. His Engineering background in addition to his Prosthetics and Maxillofacial clinical experiences helped him in achieving interesting outcomes on his researches. At his current position, he is involved with undergraduate, Post-graduate teaching as well as regularly running external courses such as CPD courses. He is also an international speaker.
Abstract:
Maintaining a good posture helps practitioners to achieve superior outcomes and protects them from future problems such as back pain. This is the central theme of the course. Having a correct position allows the practitioner to see the working areas properly which optimizes performance and avoids iatrogenic damages. Some clinicians think that having their eyes closer to the working area would help them to have better control of their handpiece. Yet, being too close to the targeted surface area would not only decrease the level of accuracy, but also create discomfort for the patient. When practitioners have to move their head or change their posture to check the task done, it means that at the time of the procedure the clinician was not able to see the working surface area correctly. Not having the most suitable posture for the task would most likely let your treatment outcomes down. Studies demonstrate that about 85.5% of clinicians have a forward head posture, while 68.8% have a round shoulder posture. More interestingly 36.1% of practitioners suffer scoliosis and hyperlordosis. Most of the work postures studies demonstrate a high risk to the lower back and neck however, even with an appropriate posture muscle strengthening exercises for the neck can play an important role minimizing the risk. There are some situations where the practitioner stands to do tasks such as extracting a tooth or taking impressions.

Cristian Scognamiglio
University of Insubria School of Medicine, Italy
Keynote: Analysis of the height/width ratio of peri-implant soft tissues in different types of implant connections and oral sectors
Time : 11:05-11:50
Biography:
Cristian Scognamiglio has completed his degree in Dentistry and Oral Surgery at the University of Insubria (Varese-Italy). He is an international speaker providing lectures on surgery topics and organizes practical workshops (regarding Suture Techniques and Implant Positioning). He is an author of different scientific papers published on international editorials and congresses. In 2018, thanks to one of his studies, he won the prize as the Best Scientific Research in Oral Surgery issued by the Italian Society of Periodontology and Implantology.
Abstract:
Modern implantology has been focused on the peri-implant mucosa maturation patterns, with particular attention on the frontal area, aiming to obtain a functional and aesthetic optimal result. The study analyzed 294 implants, in order to obtain a tridimensional model; the measurements were done with digital 3D technology at one year from the provisional crown placement. All the recorded data were analyzed with Test Pearson 2-Tailed (95% confidence range) by IBM. For the research we measured the width of the peri-implant mucosa, calculated from the implant connection to the buccal mucosa surface on a line perpendicular to the main implant axis. For the height of the peri-implant tissues, we considered as well, the same geometrical line as the apical point of the measure to calculate the perpendicular distance to the most coronal gingival point. The purpose of the following study is to give the guidelines for a correct implant positioning respecting the biological rules, in addition, it analyzes the height/width ratio of the peri-implant buccal tissues between different type of connections and comparing different areas in the oral cavity. The present research compares the ratio between the height/width of the peri-implant mucosa considering the variables of the residual buccal bone and the difference in six implant brand, finding some important relations.

Abstract:
It is astonishing how everything around us is evolving so fast, and today we manage to include the elements of the past in our present. There is a long history of the use of plants to improve dental health and promote oral hygiene and it is still commonly practiced among Afro-Asian communities. The plant parts when used in this manner are commonly referred to as the “chewing stick”. In India they call it “datun”. Its use still remains in the modern era of dentistry. But, is it really effective? In order to answer this question, I performed a research at Bodhi Tree school, Bodhgaya, India in august 2018, on a total of 129 students (60 female and 69 male), aged between 7-16 years. The students were split up into four groups: I (7-9y), II (10-13y), III (14-16y) and IV children with special needs. I completed the general dental check up and the incidence of colorations, dental calculus and cavities were observed. In addition, I investigated the percentage of the students which used datun (chewing stick) and those who used toothbrush for the oral hygiene. The main goal of the research was to investigate the effectiveness and the beneficial effects of the chewing stick. With the help of PubMed, Science Direct and with my results, the present study was able to lead to the really interesting and important results. Thanks to this experience and the workflow, my research won the first prize at the International Dental student Congress Dentisium 2018.

Abstract:
Aim: The aim of the present study was to evaluate the shade change of three manufacturers of translucent resin cements on the final color of ceramic veneers.
Materials & Methods: Thirty (30) disk-shaped ceramic specimens (IPS e. max, 0.6 mm x 7.00 mm diameter) and 30 composite resin background specimen blocks were fabricated (3 mmx10 mm diameter). They were then divided into three groups, each group containing 10 ceramic disks and 10 composite disks. The ceramic disks were cemented on the composite resin background blocks using translucent cement from three different manufacturers. (Group 1 - Variolink Esthetic LC Neutral by Ivoclar Vivadent, Liechtenstein; Group 2 - eCEMENT Translucent by Bisco, USA; Group 3 - RelyX Veneer Cement Translucent by 3M ESPE, USA). A spectrophotometer (VITA EasyShade Advance) was used to measure the color parameters before and after cementation. The color differences were then statistically analyzed using one-way ANOVA. Significance was set to P<0.05.
Results: The final shade of the ceramic veneers showed the most significant changes in ΔE value for the translucent shade from eCEMENT by Bisco while Variolink and Relyx showed a less significant color change. However, all three translucent cements exceeded the clinically acceptable threshold of ΔE>3.3.
Conclusions: The three brands of translucent resin cement produced clinically noticeable shade change on the ceramic veneer with Variolink Esthetic cement (Group 1) having the least effect on the color of the ceramic and eCEMENT (Group 2) producing the most color change.
Amandeep Bains

Abstract:
We are presenting a case highlighting the importance of preservation of mentalis muscle attachment during genioplasty procedures. This patient received a bimaxillary osteotomy in 2013 (aged 17) followed by a genioplasty in 2014. Unfortunately, the patient suffered from bilateral mental nerve distribution paraesthesia, however was originally happy with the overall aesthetic outcome. In April 2016, the patient was referred to Wythenshawe Hospital regarding muscular irregularity of the mentalis region, creating a dimpled and an unsatisfactory appearance. The patient was listed for scar revision and adjustment of mentalis attachment under general anaesthetic. The authors feel this case highlights the importance of soft tissue management during orthognathic procedures. Orthognathtic surgery delivers important functional improvements but also significant aesthetic outcomes. These outcomes were originally well met by good hard tissue management; however they have been compromised at a later date by poor soft tissue management. The two year delayed presentation is further indication to highlight this complication of genioplasty as there is opportunity for this to be missed on regular short-term follow ups. This complication and thus the subsequent management are relatively rare and we believe this case may be beneficial to bring to the attention of the Maxillo-Facial community.
Francis Muthama
Kinga Africa, Kenya
Title: Infant oral mutilation (IOM) a world dental concern
Time : 15:00-15:30
Biography:
Abstract:
Infant Oral Mutilation (IOM) is a primitive practice widely accepted and adored among many communities in Africa, though not widely talked about. Young children presenting with diarrhea and fever are subjected to the extraction of deciduous tooth buds, most commonly canines, (these they say are disease causing worms) as an accepted remedy for their illness. When tooth buds are extracted they exhibit a milky appearance and the village healer shows the parents so that they can see and feel the worms supposedly causing the child’s illness. Traditional healers and birth attendants (TBAs) perform the practice. It is a belief that whenever a bone is broken or blood is shed, payment must be made to the TBA to ensure that recovery is quick and not followed by a “bloodshed curse”. Instruments used for these procedures include penknives, metal blades made from spoon handles or bike tire spokes, and sharp fingernails. The instruments used are often not sterilized, and no topical anesthesia is used. The practice is responsible for new HIV and other infections and also missing or crooked permanent teeth. As the president of Kinga Africa, I wish to do an oral presentation on this topic and the role of dental education in alleviating this practice. It will be great sharing the achievements and successes the action against IOM, program has achieved. The world must be aware of this and it must stop.
Ahmed Abosabaa
Delta University for Science and Technology, Egypt
Title: The effect of two different solitary attachments used to retain implant assisted mandibular distal extension removable partial overdenture on abutment alveolar bone height changes
Time : 15:30-16:00
Biography:
Ahmed Abosabaa has completed his Bachelor’s degree from the Faculty of Dentistry, Tanta University in 2009. He became a member of the Royal College of Surgeons of Edinburgh in 2012 after passing MFDS exam and completed Master’s degree in Prosthodontics from Mansoura University in 2018 which is based on implant assisted partial overdentures.
Abstract:
Objectives: The main objective of this clinical comparison study was to compare between different designs of solitary attachments used to retain implant assisted mandibular distal extension RPD regarding alveolar bone height changes around abutment teeth.
Methods: Twelve patients with mandibular Kennedy Class I were selected for this study. The remaining natural teeth were extended from the first premolar on one side to first premolar on the other side. One implant was placed in each first molar region bilaterally. The removable partial dentures were retained anteriorly by RPA clasp design and posteriorly either by ball attachment (group I) or by OT-equator attachment (group II). Alveolar bone height changes around the primary tooth abutments were radiographically evaluated using cone beam volumetric CT.
Results: Regarding bone loss around the primary abutment teeth, ball attachment group (0.72±0.15) significantly (p value=0.008) showed less crestal bone resorption when compared to OT-equator attachment group (1.01±0.25).
Conclusion: Within the limitation of this study and regarding the preservation of abutment teeth, the use of ball attachment may be the suitable choice for anchoring distally extended removable partial denture to dental implants with improved longevity of the natural tooth abutments.
