Orthodontic retraction biomechanics for space closure and distalization using...Vishnu Patel Ortho
Centre of Resistance Simulator is an Innovative Customized Orthodontic Appliance for Retraction of Protruded dentition especially proclined upper front Teeth.
Biomechanics of Extraction Space Closure with Sliding Mechanics has been elaborated mathematically using Equilibrium Force Diagram.
Comparatively Simple and Statically determinate Force system using the Centre of Resistance Simulator (CRS) has been described.
Vertical Anchorage Control has been challenging task in patients having Long Faces and high Mandibular Plane Angle (Vertical Growers). This concept of Simulating Centre of Resistance facilitates vertical Anchorage control during Extraction Space Closure without Temporary Anchorage Devices (Microimplants or Bone Screws). Judicious use of TADs is definitely required for En Masse Distalization cases and absolute Anchorage demanding extraction cases e.g. extreme long faces where maximum extraction space is to be utilized for Retraction of Anterior Teeth Segment.
Bodily Retraction of Upper Anterior Teeth without bite deepening and without Molars extrusion ( i.e.opening of Mandibular Plane Angle) is also possible with the concept.
This appliance may also be used in patients having lingual braces and clear aligners for improving outcome.
This Orthodontic Force System provides Frictionless and Loopless Retraction Mechanics for Extraction Space Closure.
Designing of the appliance on Cephalometric Tracing and then accordingly locating estimated Centre of Resistance on Models has been mentioned stepwise in the video.
Techno Savvy young Orthodontists can design and fabricate CRS by CAD-CAM using 3D designing softwares and DMLS 3D Printing.
Biomechanical explanation of each minute sense has been described in this video. Please watch and listen carefully from start to finish in one go.
I humbly request to all Orthodontists especially those affiliated with Institutes to explore the concept. I will be more than happy to be involved in such work.
Please feel free to contact me on vishvadental@gmail.com for detailed insight.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

2. WHAT IS A DENTAL IMPLANT?
Dental implant is an artificial titanium fixture
(similar to those used in orthopedics)
which is placed surgically into the jaw bone to
substitute for a missing tooth and its root(s).

lower jaw, back – 85 – 90%
upper jaw, front – 85 – 95%
upper jaw, back – 65 – 85%www.indiandentalacademy.com
4. History of Dental Implants
In 1952, Professor Per-Ingvar Branemark,
a Swedish surgeon, while conducting research
into the healing patterns of bone tissue,
accidentally discovered that when pure titanium
comes into direct contact with the living bone
tissue, the two literally grow together to form a
permanent biological adhesion. He named this
phenomenon "osseointegration".

5. First Implant Design by Branemark
All the implant designs are obtained by the
modification of existing designs.

8. The FEA of the 3.5 mm Bicon
Implant-Abutment-Bone system under
central occlusal loads
Assumptions:
• Analyses were linear, static and assumed that materials
were elastic, isotropic and homogenous.
• 100% osseointegration is assumed between bone and
implant. Bone and implant are assumed to be perfectly
bonded.
• The stresses in the bone due to the interference fit between
implant and abutment is assumed to be relaxed after the
insertion of the abutment.www.indiandentalacademy.com

10. RESULTS
Effect of bone’s elastic modulus on the overall
stress distribution: Different finite element analyses
are run by varying bone mechanical properties
surrounding the implant. (1-16 GPa)
The properties of the bone depends on the location in
the jaw, the gender and age of the patient.

12. • Both the stress distribution and the stress levels
are effected significantly as the bone modulus is
varied.
• CT scan data may be a good source for obtaining
patient dependent implant designs.

13. Maximum vertical and lateral load carrying capacity of
the bone:
The failure limit of the bone due to fatigue is 29 MPa.
[Evans et al.]
Force: Vertical 920 N
Bone Modulus: 10 GPa
Force: Lateral 40 N
Bone Modulus: 10 GPa
Lateral loads cause approximately 25 times higher
