Abstract:
Implant placement in severely atrophic jaws is especially challenging because of the poor quality and quantity of the future
implant bed. When there is a loss of teeth, atrophy of the alveolar processes occurs in a vertical as well in a horizontal plane. Restoring severely atrophied cases can be very challenging due to the proximity of the sinuses and nerves and the resorption of the alveolar crest. Usually bone grafts, mental nerve displacement and sinus lift procedures are used to overcome the initially poor anatomical and mechanical conditions of such cases. But severe atrophies may be rehabilitated within 10 days with a fixed denture thanks to the Cortically Fixed at Once (CF@O) approach. The CF@O protocol uses the remaining bone for fixing cortical implants. Its specificity is that no bone graft, no sinus lift and no nerve displacement are used. It uses specific designed plate implants, with a shape ranging from 41-43 mm in length. These solid titanium hybrid plates possess a high fatigue strength level with no welds or added parts. They are particularly indicated for mechanically demanding situations.

Abstract:
Ceramic laminates are a spectacular alternative for aesthetic corrections with minimal wear of sound dentin structures. This
technique described here presents the concepts of minimally invasive wear, based on ultraconservative cavity preparation,
that aim only to obtain axes of insertion of the slides. In current aesthetic dentistry, it is fundamental for an adequate planning
to use tools that enable the team of professionals and patients to interact in the construction of the esthetic rehabilitation
proposal. The aesthetic need of our patients is increasing every day and the attention given to this stage of treatment must be
very great. Just as we espouse the philosophy of virtual smile design and custom diagnostic waxing, color selection and color
mapping must follow rigorous concepts, so that we have jobs at spectacular levels. We intend to present several clinical cases
of aesthetic rehabilitation, following a rigorous clinical and laboratory protocol, aiming at extremely satisfactory final results.
We use the name of high performance dentistry because this protocol seeks a careful evaluation during the stages of diagnosis and planning, so that the following stages, development of clinical and laboratory work are very fast, objective and correct. We will present clinical cases involving periodontal plastic surgery, bioplasty, digital smile planning and various dental whitening techniques, minimally invasive preparations, physical and virtual molding techniques, color selection and color mapping, cementation and final adjustments. All this, with the ultimate goal: a big and beautiful smile, full of health and function.

Mahmood Qureshi
Pakistan Academy of Implant Dentistry, Pakistan
Keynote: The bone renaissance
Time : 11:40-12:20
Biography:
Mahmood Qureshi is one of the acknowledged international mentors and a leading dental implant and oral reconstructive surgery expert. He has developed and modified several surgical techniques and instruments and is the originator of the ‘2 IC' Universal Concept and 'Sabirin'- a unique philosophy of treating the untreatable
patients. He has developed MQMET - a revolutionary and an innovative implant placement system. He is the Founder of the 1 year post graduate curricula in Implantology; Editor of the International Journal of Implants; an international course presenter; has lectured extensively and conducted over 1000 professional
presentations on Implantology in five continents
Abstract:
Introduction: In a relentless pursuance of perfection and a definitive solution for long term stability of tissues around dental implants, the author will present an exceptional concept - the ‘Bone Renaissance’- a unique philosophy encompassing the sequential and codified reversal of the bone back to its original 3-D Engineered Divine Osseo-architecture (com'era, dov'era); by incorporating the 5 in 1 modus operandi: ‘SABIRIN’ (Stable Alveolar Bone Implant Reconstructive Integration Naturally), a major paradigm shift in re-establishing the natural spiritual union of the form and function.
Analysis: Loss of teeth always leads to the shrinkage of jaw bone at the extraction site with a 50-70% bone loss in height and
width over a period of 2-4 years resulting in unaesthetic facial lines, increase in size of maxillary sinus, over closure, prognathic
appearance, reduced horizontal labial angle of lip, loss of tone in muscles of facial expression causing functional, anatomical
and cosmetic problems. A typical patient, with existing edentulous areas and desiring implant treatment doesn’t have adequate
bone to permit implants to be placed into normal root locations. This atrophy is a dynamic functional loss as the bone heals
and changes from stress bearing to non-stress bearing bone for implant placement.
Methods: Sabirin components: Bone Renaissance Implant placement with especial Osteotomes, Soft Tissue manipulation,
Vascularized Osteotomies, Sinus & Onlay Grafts, Autologous Growth Factors and Stem Cells.
Results: The refurbishment of patients to innate curve, contour, aesthetics and function is achieved by using SABIRIN
components which resurrect the lost contours of hard and soft tissues with a long-term, aesthetic predictability.
Discussion: Based on the 25 years of experience, the presenter thoroughly discusses the rationale, gives practical guidelines
and presents surgical maneuvers to rectify hard & soft tissue deficiencies complemented by CGF to enhance facial aesthetics.

Title: Treatment of severe idiopathic gingival fibromatosis in mixed dentition
Biography:
Virgílio Roriz has completed his PhD from University of São Paulo, School of Dentistry, Riberirão Preto, SP. He is the Professor in Federal University of Goiás
School of Dentistry, Department of Periodontics. He has published more than 16 papers in national and international journals.
Abstract:
Gingival fibromatosis may occur as an isolated finding or in combination with additional clinical problems associated with some syndromes. It may result in difficulties with proper dental hygiene keeping, chewing and occlusion. This work aims to describe a case of a child that was submitted a periodontal surgery for tissue removal caused by severe idiopathic gingival fibromatosis (IGF). The case study begins with a 10 years old male patient reported that presented a very large gingiva and he related about difficulty of tooth brushing. As treatment for resolution of the case, it was opted for the gingivectomy
surgery. This procedure was performed using the internal bevel technique with blade 15c at 45º with the alveolar bone crest, surrounding all the vestibular teeth’s faces and the palatine faces of the molars, removing about 4mm of gingival tissue. During urgery, teeth 64, 65 and 84 were extracted due they presented great mobility. A small part of this material was sent for histopathological analysis. Histological sections revealed the presence of an epithelial lining showing marked acanthosis and additionally, connective tissue hyperplasia was observed, such findings compatible with fibroepithelial hyperplasia. Based on medical history, clinical examination and histopathological study of gingival tissue biopsies the patient was diagnosed with IGF. After six months of follow-up, the patient was very satisfied with the aesthetic and functional results because the crowns were much more exposed in the oral cavity, facilitating mastication and hygiene.

Abstract:
Background: GTR technique is the gold standard for periodontal intrabony regenerative therapy. The aim of this study was
to evaluate the effect of using L-PRF and EMD growth factors along with GTR technique for regeneration of periodontal
intrabony defects.
Methods & Materials: Forty-five intrabony defects resulted from periodontal disease which can be reconstructed were enrolled in the study. Group 1 just got GTR treatment as control group, group 2 got L-PRF along with GTR treatment and in group three EMD used along with GTR. Clinical factors such as periodontal probing depth (PPD), clinical attachment level (CAL), keratinized gingival width (KGW) and bleeding on probing (BOP) were evaluated before and six months after treatment. Also amount of bone fill was evaluated with standard radiography.
Result: Treatment in all three groups significantly result in reduction of PPD and gaining of CAL. Sites with BOP significantly decreased, defects significantly filled with bone, however, there was no significant difference in KGW. Intragroup comparison showed no significant difference among groups in evaluated factors. But the most PPD reduction was 5.4±1 in L-PRF+GTR
group, the most CAL gain was 3.37±2 in GTR group, the most reduction in BOP sites were 14 sites in L-PRF+GTR groups and the most bone fill was 73% in GTR group.
Conclusion: Using EMD or L-PRF along GTR treatment does not have additional effect on positive results of GTR treatment alone.

Title: Enamel demineralization around metal and ceramic brackets: In vitro study
Biography:
Objective: The objective of this study was to evaluate the degree of enamel demineralization of teeth bonded with ceramic and metal brackets.
Materials & Methods: In this cross-sectional experimental in-vitro study, 60 extracted human premolar teeth were selected according to certain criteria. They were divided into three groups; 20 premolar teeth in each group. Teeth in group-1 were bonded with APC Plus Adhesive Ceramic brackets, and teeth in group-2 were bonded with APC Plus Adhesive Metal brackets, while teeth in group-3 were not bonded with any brackets “control group”. All groups were then immersed in demineralization media, de-bonded, sectioned into three parts (proximal-1, middle, and proximal-2), and evaluated in the aspect of enamel
demineralization under Scanning Electron Microscope.
Results: On tooth level, the results show that the control group has significantly less enamel demineralization compared to the two experimental groups with mean value of 145.3μm and 192.7μm, respectively (P=0.000). The mean value of enamel demineralization in metal group is 55.93μm compared to 72.55μm in ceramic group, which is significantly less (P≤0.05), while there is no difference between the control and metal group with regard to enamel demineralization. On section level, the control group has significantly less enamel demineralization in all three sections compared to the ceramic group, while the significance is found in one of proximal section when compared with the metal group. Moreover, the ceramic group has significantly higher enamel demineralization in the middle section compared to the metal group (73.54μm, 46.5μm respectively) (P=0.000), while there is no statistical significant difference between the two experimental groups in proximal sections.
Conclusion: Non-bonded teeth have showed least demineralization compared to bonded teeth. Moreover, teeth bonded with ceramic brackets have showed significantly higher demineralization compared to teeth bonded with metal brackets.
