Intra-oral prosthetics are artificial substitutes used to improve speech and swallowing for those missing oral structures due to conditions like head and neck cancer, cleft palate, or injuries. They are placed in the vocal tract and designed by a multidisciplinary team including speech language pathologists and surgeons. SLPs play a key role in determining patient needs, selecting the appropriate prosthetic type like palatal lifts or obturators, assessing effectiveness, and providing follow-up treatment and monitoring of swallowing and speech. Prosthetics have limitations but can help restore functions like velopharyngeal closure, separation of oral and nasal cavities, and tongue movement for speech.
This document discusses implant biomechanics and osseointegration. It notes that osseointegration occurs when an implant bonds to living bone, providing long term stability. Biomechanics involves the interaction between forces and tissues in the body. Key factors for implants include force magnitude and direction, as well as moment arms related to implant location and design. Proper implant selection, placement, and occlusion are important to minimize these forces and moments to prevent implant failure.
Removal partial denture considerations in maxillofacial prostheticsBibin Bhaskaran
Removal partial denture considerations in maxillofacial prosthetics discusses interim, definitive, and surgical considerations for prosthetics following maxillofacial defects. Interim prosthetics aim to separate oral and nasal cavities and improve swallowing/speech. Definitive prosthetics restore function after tissue healing. Surgical preservation of teeth and tissues benefits prosthetics by providing support and retention. Mandibular reconstruction challenges include soft tissue bulk and bone placement impacting function.

This document describes the fabrication and use of an acrylic guidance flange prosthesis for a patient who underwent a hemisection of the mandible due to ameloblastoma. Loss of mandibular continuity can cause deviation towards the surgical side and altered jaw movement. The prosthesis helped guide the mandible into the correct intercuspal position and re-educate the muscles. Within 3 weeks of using the prosthesis and undergoing physiotherapy exercises, the patient was able to achieve proper occlusion without assistance. Guidance prostheses can successfully restore function for patients with mandibular defects when combined with physiotherapy.
obturators / prosthodontic management of maxillectomy - part 1NAMITHA ANAND
This document provides an overview of maxillofacial prosthodontics. It discusses the role of the prosthodontist in rehabilitating patients who have undergone maxillectomy or mandibulectomy surgery. It describes various classification systems for maxillary and mandibular defects. It also outlines pre-surgical and post-surgical prosthodontic procedures like interim and definitive obturator prostheses. Historical developments and recent advances in materials used for maxillofacial prostheses are also summarized.
This document discusses several key points regarding dental implants:
1) Bone density and quality greatly impact implant success, with the highest success seen in the anterior mandible and lowest in the posterior maxilla due to poorer bone density.
2) Treatment planning considerations include implant placement based on available bone, with a minimum of 3 implants to replace missing posterior teeth in the maxilla.
3) Linear implant configurations are less stable than curved arrangements and more prone to overload from non-axial forces, particularly in low-density posterior areas.

This document discusses biomechanics as it relates to dental implants. It covers several key points in 3 sentences:
Biomechanics aims to understand the physiological and non-physiological loads placed on implants and how implant design and surrounding tissues interact to distribute forces. Osseointegration provides a direct bone-implant interface to transmit stresses but cylindrical implants are at highest risk for shear forces. Several biomechanical factors like implant design, bone quality, occlusion, and parafunction can influence long term implant success and complications like screw loosening if forces exceed the implant's tolerance.
This document discusses the prosthodontic rehabilitation of patients who have undergone mandibulectomy. It describes different classifications of mandibular defects and the goals of mandibular reconstruction. Key diagnostic considerations for prosthodontic treatment are discussed such as the location and extent of the defect, remaining teeth, jaw rotation, and mouth opening. Surgical reconstruction techniques and approaches to rehabilitation for partially or fully edentulous patients are presented, including the use of implants, guidance prostheses, and overlay dentures. Close follow-up is important when rehabilitating mandibulectomy patients prosthodontically.

This document discusses mandibular fractures, including:
- The uniqueness of the mandible as the only mobile bone in the facial region with bilateral joint articulations.
- The biomechanical aspects of fractures, which tend to occur in areas of tension due to irregularities in the mandibular arch.
- Treatment options including closed reduction with fixation, open reduction with rigid fixation using plates, screws or external pin fixation.
- Factors determining the appropriate treatment and length of intermaxillary fixation.
prosthodontic management of maxillectomy/obturators part 2 final copyNAMITHA ANAND
This document discusses implant placement and rehabilitation of maxillectomy defects. Some key points include:
- Implants can be placed in residual bone of the anterior maxilla, tuberosity, pterygoid plates, or zygomatic arches to aid in retention of obturator prostheses.
- Survival rates are lower in irradiated patients and anterior maxilla. Posterior implants have higher survival.
- Bone loss can occur if implants receive excessive occlusal forces.
- Tissue bar attachments are commonly used to connect implants and aid in prosthesis support and stability.
- Zygomatic implants can be used in large defects but oral hygiene is difficult.
this is basic seminar on implant retained maxillofacial prosthesis including that which are the different types of facial defects and how are they rehabilitated with implants.

Alveolar bone forms in conjunction with tooth development to support teeth and give attachment to muscles. It is composed mainly of hydroxyapatite and collagen and contains osteoblasts, osteocytes, and osteoclasts. The alveolar bone undergoes remodeling through the balanced actions of osteoblasts, which form new bone, and osteoclasts, which resorb old bone. This allows the alveolar bone to maintain its shape and position relative to the teeth. Interruptions in the bone like fenestrations and dehiscences can complicate dental procedures or lead to issues like gingival recession.

This document discusses distraction osteogenesis, a technique used to regenerate bone by gradually separating bone segments. It was introduced in 1951 by Ilizarov who used external fixation devices. The key steps involve cutting and separating the bone followed by slow distraction of 1mm per day which stimulates new bone formation. Both extraoral and intraoral devices are described. Applications include lengthening of the mandible for conditions like micrognathia. The process relies on stability of fixation, controlled distraction rate, and preservation of soft tissues. It allows reconstruction of craniofacial bones without growth factors.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

4. Implant failure
Definition:An implant failure may be defined as the
first instance at which the performance of the implant,
measured in some quantitative way falls below a
specified acceptable level.
Or can be defined as an implant that has a hopeless
prognosis.
www.indiandentalacademy.com
5. Signs and symptoms of implant failure
1) Horizontal mobility beyond 0.5mm or any clinically observed vertical movement under
<500g force
2) rapid progressive bone loss regardless of the stress reduction and peri implant therapy
3) Pain during function or on percussion
4) Dull sound on percussion
5) Continued exudation inspite of surgical attempts at correction
6) Generalized radiolucency around an implant
7) >1/2 of the surrounding bone is lost
8) SLEEPERS -Implants inserted in poor position making them useless for prosthetic support
9) Pocket depth of 5mm and increasing

11. Classification of Implant Failures
1.According to Branemark et al
• Loss of bone anchorage
- Mucoperiosteal perforation
- Surgical trauma
• Gingival problems
- Proliferative gingivitis
- Fistula formation
• Mechanical complications
- Fixture fractures
- Fracture of prostheses, gold screws, abutment screws
www.indiandentalacademy.com
12. 2. According to Misch
Surgical failure inability to place the abutment at the time
of surgery
Osseous healing failure period from implant placement to
abutment connection,is related to
healing ability of bone
Early loading failure the first year the implant serves as a
prosthetic abutment
Intermediate implant failure time period after the 1st yr of loading upto
following 5yrs of function
Late implant failure after the implant and prosthesis have been
loaded for >5yrs but <10yrs.
Long term failure failures after 10 yrs.
www.indiandentalacademy.com
13. Complications/factors leading to implant
failures
. Surgical factorsSurgical factors (early failures)(early failures)
Stage I surgery
1) Overheating of bone - necrosis,osteomyelitis
2) Lack of primary stability - bone loss
3) Infection
4) Lack of osseointegration
5) Poor placement or angulation, slips, eccentric drills
6) Damage to vital structures
7) Implant fracture
8) Inadequate no. of implants
www.indiandentalacademy.com
14. Stage II surgery
• Loose abutment
• poor fixtures
• early loading by
prosthesis
• poor abutments
www.indiandentalacademy.com
16. Implant related factors
1.Screw design:
conical screws - loosen
flat head screws - better
2.Implant body design:
smooth cylinder implant - shear force at implant-bone interface
threaded implant - can transform and change the direction of
force through thread geometry
www.indiandentalacademy.com
17. a) Shape of thread Standard v
Thread
Square
Buttress thread
www.indiandentalacademy.com
18. b) Thread pitch:
smaller the pitch more
will be the surface
c) Thread depth:
increases surface area
3. Implant length : increases surface
area4. Implant width : increases surface area
www.indiandentalacademy.com
19. Host factors
• Patient dissatisfaction with the result.
• Inadequate patient follow-up
• Failure to maintain hygiene leading to periodontal breakdown
• Parafunctional habits
• Systemic health( medical complications)
• Medications- alter tissue metabolism and repair
• Social habits like smoking, stress,alcohol abuse affect wound healing
• Poor bone quality and quantity - avascular bone,bone density,
type of bone,etc.
www.indiandentalacademy.com
20. Force delivery and failure mechanisms
Moment loads (torque or torsional loads):
is defined as a vector,the magnitude of which equals the product
of force magnitude and the perpendicular distance from the
implant
to the line of action of force.
www.indiandentalacademy.com
21. Possible rotations
A total of six rotations may develop about three clinical co ordinate axes.
www.indiandentalacademy.com
22. Clinical Moment Arms
1.OCCLUSAL HEIGHT MOMENT ARM
2.CANTILEVER LENGTH MOMENT ARM
3.OCCLUSAL WIDTH MOMENT ARM
www.indiandentalacademy.com
23. Fatigue failure
Four factors influence fatigue:
1. Biomaterial
2. Geometry of the structure -Twice thicker material have sixteen times
more fatigue resistance .
3. Force magnitude
4. Number of loading cycles.
www.indiandentalacademy.com
24. BASIC CONSIDERATION
– OCCLUSION CONCEPTS AND PHILOSOPHIES ARE NOT
BASED UPON SCINTIFIC RESEARCH AND EVIDENCE.
– THE CONCEPT THAT HAVE BEEN POPULAR FOR THE
RESTORATION OF NATURAL TEETH HAVE BEEN JUSTIFIED
BY PURELY EMPIRICAL METHODS AND HAVE HELD UP
WELL TO THE TEST OF TIME. FOR IMPLANTS THE SAME
CONCEPTS HAVE BEEN USED WHICH SERVE AS A GUIDE
LINES TO ACHIEVE OPTIMUM OCCLUSION .

BIOMECHANICS OF EACH ARE DIFFERENT.BIOMECHANICS OF EACH ARE DIFFERENT.
www.indiandentalacademy.com
26. Flocken (1984) stated that to help alleviate the potential impact forces , the teeth should
contact
simultaneously when the mandible closes into maximum intercuspation.Natural teeth can
function
effectively from this position.
Lundgren , Laurell (1984) suggested the need to minimize horizontal forces created by
premature
contacts or steep cusps.
Albrektsson,et al., (1986) emphasized the need to distribute the load mainly over the areas
supported directly by fixtures.
Jemt (1986) described that when Osseo integrated implants are used in short span FPDs
and single
tooth replacements , the occlusion should be distributed in maximum intercuspation and
all cusp
interferences should be eliminated in eccentric positions.
Lucia (1987) advocated the application of gnathological principles in development of
occlusion
in implants.
Review of occlusal scheme
www.indiandentalacademy.com
27. Misch (1991) developed IPO ‘Implant protective occlusion’ for implant supported
restorations.
IPO - Medial positioned lingualized occlusion
is based on :
- Narrow occlusal table.
- occlusal table width similar to width of implant body.
- Increasing surface area.
- Design of occlusion in favour of weakest arch.
- Decreasing force of occlusal contacts.
- Eliminating or reducing all shear loads to implant to bone interface.
- Posterior disocclusion by anterior components.
- Initial contacts on only natural teeth and later on multiple contacts on both
teeth and implants.
Norton (1995) recommended an ideal occlusal scheme for fixed implant supported
prostheses :
- A centric occlusion ‘cusp to central fossa’ contact which is light.
- An ideal anterior guidance : that is canine-guidance or group function; no posterior
interferences.
- Axial loading of the implants.
www.indiandentalacademy.com
28. Factors affecting choice of occlusal
scheme1.Arch form:
- Curve arch is favorable for less stresses
- Influences no. of implants to be placed
- Opposing arch form affects occlusion
2.Interarch distance and jaw relations :
- May prevent development of particular
occlusal scheme
- May force to adapt a particular scheme
- Affects biomechanical aspects
3. Orientation of the occlusal plane :
- Arch in which is implant is placed becomes the dominant
arch and opposing edentulous arch becomes weaker arch.
- plane should favor weaker arch.www.indiandentalacademy.com
29. 4. Abnormal mandibular movements
5. Bone support and bone mechanics :
Sullivan (1990) stated that the final form of
restoration should be development
maintaining progressive loading.
Good bone support - occlusal contacts can be increased.
6. Occlusal material :
- affects the transmission of forces.
- affects the maintenance of occlusal contacts.
Acrylic has higher wear rate, so if acrylic is to be used then heavy occlusal
contacts can’t be given. www.indiandentalacademy.com
30. 6. Zarb (1985): stated that acrylic teeth have shock absorbing effect and can be
modified for use very easily.
They should be used to decrease overloading of implants.
However selection of occlusal material depends upon :
- Opposing occlusion.
- Remaining dentition.
- Arch to be restored.
www.indiandentalacademy.com
31. 7. Attachment to natural teeth
•Hobo in 1986 recommended a non rigid attachment and a
Key and Key way type of attachment between teeth and
implant.
•Lundgren in 1986 recommended the use of Semi –
precision attachment which detaches the teeth from the
implant prosthesis allowing a tooth to move downward.
www.indiandentalacademy.com
32. • The IMZ implant system uses a Intra mobile element [IME] to
act as a shock absorber during function.
It can act as a PDL analogue.
However, Gracia in 1998 reported intrusion of the natural
supporting teeth.
•Misch: stated that biomechanical concern and difference in
Support should be understood and applied before attaching
natural teeth to implants.
He advocates initial occlusal contacts on the natural teeth.(Thin
articulating paper of 25 m should be used for this.
Once the equilibrium with a light bite force is completed, a
heavier CR occlusal force is applied to have contacts on teeth as
well as implant also, thus harmonizing the occlusal forces.
www.indiandentalacademy.com
33. Heavy bite force is used because it depresses the natural teeth positioning
them close to infra occluded or depressed implant position and equally
sharing the load.
Only possible advantage is additional support to convert
cantilever design to fixed one.
8. Quality of Osseo integration
Its is the ability of implant to bear occlusal load .
It depends upon:
1. Implant length , width, design, surface coatings.
2. Number of implants, position of implants, orientation of implants.
www.indiandentalacademy.com
34. 1.Implants opposing implants with cantilevers

restorations except the distal cantilever unit , where 100 microns
