Fabrication of functional complete dentures for edentulous patients who have undergone hemimandibulectomy is a very arduous and demanding endeavor.
The most challenging situation encountered during this procedure is the deviation of the mandible to the resected side. The deviation of the mandible to the resected side is directly proportional to the loss of tissues in the area hemi-mandibulectomy has been performed.
In cases with Cantor and Curtis classes II, III, IV, and V, guide flange prosthesis would be a treatment modality. For guide flange prosthesis to be effective, the sufficient number of posterior teeth that are periodontally sound should be present in the opposite arch.
In patients where reconstruction is not done after resection of the mandible, scar tissue formation occurs over a period of time that stiffens the tissues and worsens prosthetic rehabilitation, leading to compromised treatment planning.

Clear Aligners are the modern alternative to fixed braces. They are removable, transparent, customised, comfortable, with fewer dental visits. The ever-increasing popularity of clear aligners can be seen with today's well-informed patients. However, still some doubts persist in the minds of patients as well as general practitioners.
hai this is a nice seminar and inculcated all the recent materials and biomaterials and biomechanics of the invisalign techniques , materials to be used and clinical aspects just have a look to it
Once novel, Invisalign is now a digital orthodontic appliance used to treat millions of patients. This customized appliance is created by the aid of sophisticated 3D imaging and animation tools that enable virtual simulation of tooth movements. Tooth movements resemble a filmstrip, and each frame is called a stage. Each stage corresponds to a set of clear plastic aligner trays. As the trays are worn by the patient, every tray pushes the teeth 0.25-0.33mm at a time (Tuncay 2006). Each tray or aligner is composed of clear, removable polyurethane, which provides esthetic and more comfortable appliance wear experience than the traditional fixed appliances. This unique and esthetic alternative to tooth movement continues to recruit more patients to orthodontic therapy.

Clear aligner (Invisalign) therapy was developed in the late 1990s by Align Technologies based on earlier clear plastic appliances. It uses a series of clear, removable aligners to gradually move teeth into the desired position based on a digital treatment plan. Key advantages include esthetics, comfort, oral hygiene, and visualization of the planned tooth movement. Indications include mild malocclusions while contraindications include severe crowding or skeletal issues. Attachments are added to enhance tooth movement. Proper aligner fit is important to achieve the planned results.
An immediate denture is a removable denture that is fabricated and inserted on the same day as tooth extractions. There are two types: a conventional immediate denture, where posterior teeth are extracted first to allow healing before removing anterior teeth and relining the denture; and an interim immediate denture, where all teeth are extracted at once and a second new denture is fabricated after healing. Immediate dentures can help maintain appearance and jaw function after tooth loss but may be less retentive initially than traditional dentures due to ridge changes during healing.
Implant Introduce New Era in Orthodontic Treatment discusses the use of temporary anchorage devices (TADs) like mini-screw implants in orthodontic treatment. It provides background on dental implants and defines TADs. The document discusses the parts, materials, insertion technique, applications, advantages and limitations of TADs. It describes appropriate sites for TAD placement and risks. The document concludes that TADs have become increasingly popular due to their easy use, versatile designs and ability to allow immediate loading, facilitating treatment for difficult cases.
The document discusses clear aligners, including their fabrication process, biomechanics, and use for different tooth movements. Clear aligners are manufactured using computer software to plan tooth movements and create a series of clear plastic aligners to gradually guide teeth into alignment. While clear aligners can be used to treat many malocclusions, some tooth movements like extractions require additional auxiliaries for optimal results.
This document describes an atypical case of an immediate denture fabrication. A 78-year old woman had a failing fixed partial denture spanning her entire maxillary arch attached to only one mobile tooth. Due to her lifestyle needs, extracting all teeth and fabricating an immediate denture was necessary. The remaining fixed prosthesis and single tooth were extracted and an immediate denture was chairside fabricated. Conventional immediate denture procedures were not possible due to the extensive fixed prosthesis. The patient was comfortable with the immediate denture until a new definitive denture could be made after healing.

Emphysema is a disease condition of respiratory system.
Emphysema is an abnormal permanent enlargement of the air spaces distal to terminal bronchioles, accompanied by destruction of their walls and without obvious fibrosis.
Emphysema of lung is defined as hyper inflation of the lung ais spaces due to obstruction of non respiratory bronchioles as due to loss of elasticity of alveoli.
It is a type of chronic obstructive
pulmonary disease.
It is a progressive disease of lungs.
Sectional dentures for microstomia patients.pptxSatvikaPrasad
Microstomia, characterized by an abnormally small oral aperture, presents significant challenges in prosthodontic treatment, including limited access for examination, difficulties in impression making, and challenges with prosthesis insertion and removal. To manage these issues, customized impression techniques using sectional trays and elastomeric materials are employed. Prostheses may be designed in segments or with flexible materials to facilitate handling. Minimally invasive procedures and the use of digital technologies can enhance patient comfort. Education and training for patients on prosthesis care and maintenance are crucial for compliance. Regular follow-up and a multidisciplinary approach, involving collaboration with other specialists, ensure comprehensive care and improved quality of life for microstomia patients.

●Electrical activity has two phases:
Depolarization- contraction of muscle
Repolarization- relaxation of muscle
ECG Leads:
●6 Chest leads
●6 Limb leads
1. Bipolar Limb Leads:
Lead 1- Between right arm(-ve) and left arm(+ve)
Lead 2- Between right arm(-ve) and left leg(+ve)
Lead 3- Between left arm(-ve)
and left leg(+ve)
2. Augmented unipolar Limb Leads:

clavicular line
V5:Over left 5th intercostal space on the anterior
axillary line
V6:Over left 5th intercostal space on the mid
axillary line.
Normal ECG:
Waves of ECG:
P Wave
•P Wave is a positive wave and the first wave in ECG.
•It is also called as atrial complex.
Cause: Atrial depolarisation
Duration: 0.1 sec
QRS Complex:
•QRS’ complex is also called the initial ventricular complex.
•‘Q’ wave is a small negative wave. It is continued as the tall ‘R’ wave, which is a positive wave.
‘R’ wave is followed by a small negative wave, the ‘S’ wave.
Cause:Ventricular depolarization and atrial repolarization
Duration: 0.08- 0.10 sec
T Wave:
•‘T’ wave is the final ventricular complex and is a positive wave.
Cause:Ventricular repolarization Duration: 0.2 sec
Intervals and Segments of ECG:
P-R Interval:
•‘P-R’ interval is the interval
between the onset of ‘P’wave and onset of ‘Q’ wave.
•‘P-R’ interval cause atrial depolarization and conduction of impulses through AV node.
Duration:0.18 (0.12 to 0.2) sec
Q-T Interval:
•‘Q-T’ interval is the interval between the onset of ‘Q’
wave and the end of ‘T’ wave.
•‘Q-T’ interval indicates the ventricular depolarization
and ventricular repolarization,
i.e. it signifies the
electrical activity in ventricles.
Duration:0.4-0.42sec
S-T Segment:
•‘S-T’ segment is the time interval between the end of ‘S’ wave and the onset of ‘T’ wave.
Duration: 0.08 sec
R-R Interval:
•‘R-R’ interval is the time interval between two consecutive ‘R’ waves.
•It signifies the duration of one cardiac cycle.
Duration: 0.8 sec

3. INTRODUCTION
• The first clear aligner was introduced by Kesling in the
early 1940s. Although it didn’t gain much popularity
back then, now a days, with the development of dental
materials and 3D technology, clear aligners became more
popular.
• Invisaligns are an alternative to traditional braces and are
designed to help guide teeth into there proper position by
using a gradual force, but without metal wires or
brackets.
4. • Its made up of a transparent, thin plastic material
formed with CAD-CAM (computer-aided-design and
computer-aided-manufacturing) laboratory techniques.
• Each aligner is planned to move the teeth a maximum
of about 0.25 to 0.3 mm in 2 week.
• For maximum effective treatment , the appliance has to
be worn a minimum of 20-22 hours a day and 400 hours
in total(20 days).
• Invisalign uses less force compared to braces during
teeth straightening.
7. INDICATION
• Malaligned and Mild crowded teeth (1-5 mm)
• Class II div 2 cases (deepbite)
• Class II div 1 cases ( openbite, overejet)
• Class I (rotation, tilting)
• Class III malocclusion (underbite)
Mild to
Moderate cases
8. • Crossbite
• Spacing problems (1-5 mm)
• Narrow arches.
• Tip molar distally
• Lower incisor extraction for severe crowding cases.
11. ADVANTAGES
• The trays are aesthetic as it is clear and also
comfortable as no metal brackets or wires are there
which lead to laceration of mouth
• Clear aligners are invisible and it gives confidence to
patient to smile.
• Better oral hygiene as compared to fixed appliances.
12. • Shorter dental appointments..
• More precised treatment duration than braces
• Less frequent trips to the dental chair by allowing the
patients to replace their aligners on their own every
few weeks.
• Unaltered speech
13. DISADVANTAGES
• Very much costly.
• Removable in nature.
• Patient motivation required.
• It should be worn 22 hours/ day.
• Devices should be removed during meals.
• Missed appointments and deprived oral hygiene
lengthen treatment time and affect quality results.
14. CONTRAINDICATED CASES
• Still having primary teeth present
• Severe malocclusion cases
• Extraction cases
• Having missing teeth, it may not be able to close them
• Using dentures
• Having a dental bridge, because teeth are joined together
• Having gingival disease or periodontal disease.
• Having short, round, pegged shaped teeth.
15. EFFICIENCY, EFFECTIVENESS & TREATMENT
STABILITY ( COMPARED TO CONVENTIONAL METHOD)
Based on different research groups -
• Total treatment time: Conventional group(braces)
was significantly longer than that of the invisalign
group.
• Chair time, appointments & emergency visits:
Conventional groups required more visits, more
emergency visits, more emergency chair time and a
greater total chair time compared to invisalign groups.
16. • Treatment outcomes: According to the OGS
(objective grading system) Invisalign Did not treat
malocclusion as well as conventional braces, basically
it showed lower score for buccolingual inclination,
occlusal contact, occlusal relationships & overjet.
• Stability: The post-retention dental changes in the
invisalign group was significantly larger than that of
the conventional brace group.
17. TOOTH MOVEMENT PREDICTABILITY
Tooth movement Predictability
Crowding or spacing per arch Up to 6mm
Midline discrepancy Up to 2mm
Central incisor rotation Up to 40º
Lateral incisor rotation Up to 30º
Canine and premolar rotation Up to 45º
Molar rotation Up to 20º
Anterior intrusion Up to 2.5mm
Anterior extrusion Up to 0.5mm
Posterior intrusion Up to 0.5mm
Posterior extrusion 0mm
18. INVISALIGN AUXILIARIES
Invisalign is not based on aligners only. It requires the use
of auxiliaries such as-
• Attachments
• Interarch elastics
• Interproximal reduction (IPR)
• Altered aligner geometries (use of pressure points within
the aligner to deliver forces)
These are used to improve grip between aligner and tooth ,
which improves the predictability of orthodontic treatment.
19.
20. CONCLUSION
All in all invisalign is a great alternative to braces,
owing to its comfort level and ease to use. Though its
not very cost effective, we hope in the future newer
technology and materials will make it more affordable.
More research in the field of complex tooth movement
is still needed, but apart from that, invisalign has the
potential to replace conventional orthodontic appliance
in case of mild to moderate maloccusion.
