Lecture: Trends in Next Generation Orthodontics
Abstract: The world is moving at a rapid pace with technology improving each and every day. Some of these technological advancements are also being incorporated into the field of orthodontics and hence our speciality has grown leaps and boungs over the past few decades. We have had massive improvements in the quality of diagnostic aids, methods of treatment planning, various advancements in the appliances used in the treatment. From 2D radiographs to the development of 3D imaging, virtual planning, incorporation of artificial intelligence and 3D printing, there is a massive paradigm shift in the way in which we practice orthodontics nowadays.
Many clinics around the world have started implementing the digital workflow to improve their speed and efficiency. Digital workflow has several advanctages including less storage space as well as helps in faster and more accurate treatment planning. Virtual planning of treatment has helped us in better visualising multiple treatment plans which also improves patient acceptance to treatment. 3D printing has helped us in custom fabrication of appliances like the aligners which have revolutionised the appliance design in the aesthetic stand point.
This lecture will focus on these recent trends in Orthodontics which will equip the next generation of orthodontists in bettering their patient care and practice management.

Lecture: Customization of Implant Insertion Torque in Different Bone Densities
Abstract: Bone density is a key parameter for implant placement and is an important tool for the predictability of successful implant treatment. Various classifications of bone quality have been proposed to aid in treatment planning for dental implants. Poor bone density is a common problem resulting from defective bone formation with increase in porosity and bone fragility. Such conditions may affect the osseointegration of dental implants and some studies suggest that implants placed in low density bone have higher failure rates.
Factors that are important to the success of dental implant treatment include implant factors like biomaterial, biocompatibility, and design issues related to the dental implant; patient factors, such as general health, local tissue health, and quality and quantity of bone; and procedural factors such as osteotomy, insertion torque, timing of loading, healing duration, biomechanical loading and prosthetic design.
Osseointegration of dental implants may be affected by implant insertion torque. Implant insertion torque is directly proportional to the bone density. Many studies have been carried out to investigate the optimum insertion torque for a successful implant osseointegration. Previously implant insertion torque values that have been suggested were not customized for individual bone quality.
Bone quality and quantity are typically estimated from radiographs or at the time of implant site preparation. Bone density information obtained from CBCT and Implant insertion torque values from Finite Element Analysis investigations can give us an insight into the optimal implant insertion torque to be used for favorable osseointegration and implant success for different bone densities.
Therefore, osteoporotic patients may require modified implant insertion torque for successful osseointegration. In this presentation, implant insertion torque values have been suggested for varying bone densities so as to provide a clinical guideline for implant insertion which is patient-specific. Such new evidence can help implantology evolve from being restricted to patients with good bone densities to also include those with poor bone densities.

Lecture: Three-dimensional biomechanical analyses of dental implants
Abstract: In recent years, cross-disciplinary research on dental implants has become more and more vigorous, making studies related to dental implants more and more exciting. Using the three dimensional (3D) engineering tools, for example: computer aided design (CAD), medical imaging technique, finite element analysis (FEA), and in-vitro strain gauge experiments has become more and more popular in the researches of dental implant. In this lecture, the presenter will introduce how to apply above techniques and investigate some interesting biomechanical issues in dental implant, for example: design parameters in small diameter of dental implant, four implants supporting mandibular full-arch fixed dentures (All-on-Four treatment) and 3D bone-to-implant contact area (or ratio) in relationship to primary implant stability.

Lecture: Does Orthodontic Treatment Affect the Alveolar Bone Density?
Abstract: The purpose of this study was to assess the bone density changes around the teeth before, during, and after orthodontic treatment. Dental cone-beam computed tomography (CBCT) was employed to measure the changes in bone density around six teeth in the anterior maxilla of eight patients before and after orthodontic treatment. Each patient underwent three dental CBCT scans: before treatment (T0); at the end of 7 months of active orthodontic treatment (T1); after several months (20–22 months) of retention (T2). The Friedman test was applied to evaluate the changes in the alveolar bone density around the teeth according to the three dental CBCT scans. From T0 to T1, a significant reduction in bone density was observed around the teeth (23.36 ± 10.33%); by contrast, a significant increase was observed from T1 to T2 (31.81 ± 23.80%). From the perspective of the overall orthodontic treatment, comparing the T0 and T2 scans revealed that the bone density around the teeth was relatively constant (a reduction of only 0.75 ± 19.85%). The results of the statistical test also confirmed that the difference in bone density between T0 and T2 was nonsignificant. During orthodontic tooth movement, the alveolar bone density around the teeth was reduced. However, after a period of bone recovery, the reduced bone density recovered to its previous state from before the orthodontic treatment. However, the bone density around approximately 10% of the teeth in this region could not recover to 80% of its state from before the orthodontic treatment.
