The document discusses various aspects of maxillary sinus lift procedures:
- The maxillary sinus presents challenges for implant placement due to poor bone density and height. Sinus lift procedures aim to increase bone height for implants.
- Factors like residual bone height/width, sinus pathology, anatomical variations, and buccal wall thickness influence sinus lift technique selection.
- A thorough preoperative exam is needed to assess sinus health and rule out infections or cysts, which may require treatment prior to sinus lift. Radiographs and CT scans help evaluate sinus anatomy and pathology.
This document provides information on various ridge augmentation techniques. It begins with an introduction describing how tooth loss leads to bone resorption and impaired function. It then discusses the history of using autogenous bone grafts for ridge augmentation. The objectives of ridge augmentation are also outlined. Key techniques discussed include ridge preservation, ridge splitting, use of autogenous bone blocks, and distraction osteogenesis. Advantages and disadvantages of different graft sources and incision designs are compared. The document emphasizes the importance of adequate bone volume for successful implant placement and summarizes various methods to augment bone.
Vertical ridge augmentation is sometimes required for dental implant placement. The presentation looks at various conventional and newer techniques for ridge augmentation in the oral cavity.
This document summarizes information on sinus floor elevation procedures. It discusses the anatomy of the maxillary sinus and surgical techniques for sinus floor elevation, including the lateral window and transcrestal approaches. It also reviews complications, postoperative instructions, and the literature on success rates for different grafting materials and techniques. Based on the literature review, both lateral window and transcrestal techniques have high implant survival rates ranging from 83-100%, with rough surface implants, particulate grafts, and use of membranes associated with better outcomes.
This is a power point presentation on sinus floor elevation, describing the various techniques, biological aspects and clinical outcomes from a periodontist point of view. It also includes a brief review on the anatomy of maxillary sinus and management of complications.
This study compared ridge expansion techniques using osseodensification drilling versus conventional osteotome methods in a porcine model. Six implants were placed using each technique. Both techniques achieved similar degrees of ridge expansion, but osseodensification drilling resulted in significantly higher implant insertion torque and bone-implant contact, suggesting better osseointegration. Histologically, both techniques showed osseointegration although osseodensification drilling yielded higher stability measures. The study concluded that ridge expansion using osseodensification drilling is a predictable technique that may provide advantages over conventional osteotome methods.
1. The document discusses the importance of soft tissue integration around dental implants for long term success. Proper soft tissue seals protects the bone and prevents bacterial access.
2. Anatomy and healing of natural tooth soft tissue differs from implants, which can lead to less resistance to inflammation and slower healing for implants. Factors like gingival biotype, keratinized tissue, abutment design and mucosal thickness influence soft tissue integration.
3. Surgical and non-surgical methods are used to manage soft tissue and address factors like thin mucosa. Proper case assessment and treatment of biologic width is important for integration and preventing bone loss.

This document discusses minimal invasive techniques (MIST) in periodontal surgery. It begins by outlining some advantages of MIST such as less postoperative pain, improved healing, and better retention of soft tissues. Examples of MIST procedures described include the pouch and tunnel technique for treating gingival recession and ridge augmentation using autologous bone grafts. The document also covers papilla preservation flaps and various techniques for preserving the interdental papilla during periodontal surgery in order to maintain esthetics.
The document discusses the evolution of the concept of osseointegration in dental implants over the past few decades. It defines osseointegration as the direct structural and functional connection between living bone and the surface of a load-bearing dental implant. This is in contrast to earlier theories of fibro-osseous integration which proposed integration through fibrous tissue rather than direct bone contact. The document also examines the cellular processes of bone healing and remodeling around implants, as well as theories on the mechanism of osseointegration including distance osteogenesis, contact osteogenesis, and osteoconduction.
The document discusses the clinical evaluation of implant patients, including case types and indications, risk factors and contraindications, and the pre-treatment evaluation process. A comprehensive evaluation is needed to determine if implant therapy is possible, practical, and indicated for the patient. The evaluation should assess the patient's medical history, medications, habits, motivations, and oral examination to analyze the dentoalveolar condition and feasibility of implant placement. The patient's goals and expectations must also be evaluated to ensure realistic outcomes.

This prospective case series evaluated the use of a resorbable natural collagen membrane with a mixture of autogenous bone and anorganic bovine bone-derived mineral (ABBM) for lateral ridge augmentation to treat knife-edge ridges. 31 knife-edge ridge sites in 25 patients were treated. On average, 5.68 mm of lateral ridge augmentation was achieved after 8.9 months of healing. Histology showed ABBM was well incorporated into new bone formation. 76 implants were placed with no failures during an average follow-up of 20.88 months, demonstrating the technique can successfully augment knife-edge ridges for later implant placement.
This document discusses non-vascularized bone grafts. It notes that autogenous bone grafts are the gold standard for bony reconstruction of the jaws. Costochondral rib harvesting is described as a technique for obtaining bone grafts. The document outlines the advantages of autogenous bone grafts and principles of non-vital grafts, such as needing a blood supply from the recipient site. It provides details on harvesting and using costochondral rib grafts, including preoperative preparation, incision and procedure steps.
Bone grafting is a surgical procedure used to fill bone defects caused by trauma, tumors, or infections. There are three main types of grafts: autografts which use the patient's own bone, allografts which use cadaver bone, and synthetic grafts. Autografts are considered ideal as they possess osteoconductivity, osteogenicity, and osteoinductivity, but they require a separate donor site surgery. Allografts do not require donor site surgery but risk immune rejection. The graft incorporation process involves inflammation, new bone formation, and remodeling of the graft to become living bone. Cancellous grafts incorporate more quickly than cortical grafts.
This document provides an overview of bone graft materials and procedures, as well as first stage surgery. It discusses the history of bone grafting, defines common types of grafts like autografts, allografts, xenografts, and alloplasts. Characteristics of ideal graft materials are outlined. The document also examines graft choice considerations, various graft forms, and the biological properties and mechanisms of different materials. First stage surgery is briefly mentioned at the end.
Bone grafts are materials used to replace or augment bone. They work through osteoconduction, osteoinduction, and osteogenesis. Common graft materials used for periodontal defects include autografts obtained from the patient, allografts from other humans, xenografts from other species, and alloplasts which are synthetic grafts. Demineralized freeze-dried bone allograft is often used as it promotes bone formation through osteoinduction without the morbidity of harvesting autografts. The procedure involves graft placement in the defect followed by flap closure and post-operative care including plaque control to support healing.

This document discusses various surgical techniques used to overcome anatomical difficulties for dental implants. It covers guided tissue regeneration, ridge augmentation, maxillary sinus lift, inferior alveolar canal lateralization, and mental nerve distalization. The maxillary sinus lift technique is described in detail, including indications, contraindications, the original method, benefits and potential complications like membrane perforation. Lateralization of the inferior alveolar nerve and distalization of the mental nerve are also summarized. The document provides an overview of these procedures to help restore function and aesthetics for patients with atrophy or injury.
1) Autogenous cancellous bone graft is the gold standard but has drawbacks like donor site morbidity.
2) Allografts have risks of immune response and disease transmission but are more available. Demineralized bone matrix and ceramics are also options.
3) Composites of osteoconductive scaffolds with osteogenic cells or growth factors can enhance new bone formation compared to scaffolds alone. Bone marrow aspirate and synthetic carriers of BMPs show promise in composite grafts.

This article compares three-dimensional alterations following the use of autogenous versus allogeneic onlay grafts for augmentation at single tooth sites. Autogenous bone grafts from the chin or ramus were compared to freeze-dried allogeneic bone grafts. Cone beam computed tomography scans were used to evaluate changes in graft and defect volumes at 6 months. Both graft types resulted in significant bone fill, with autogenous grafts showing slightly more volume gain. Allogeneic grafts require less surgery time and morbidity compared to autogenous grafts.

This document provides information about bone grafts and grafting procedures in dentistry. It defines different types of grafts including autografts, allografts, xenografts, and alloplastic grafts. It describes the properties of osteoinduction, osteoconduction, and osteogenesis. It discusses various graft materials like human bone, allogeneic grafts, bone substitutes, and their advantages and disadvantages. The document also outlines objectives and techniques of bone grafting as well as factors affecting the fate of graft materials.
The document discusses osseointegration of dental implants, including the direct connection between living bone and implant surfaces. It describes different implant systems and factors affecting osseointegration like implant design/material, host site quality, surgical technique, and healing time. A two-stage surgical protocol is outlined where implants are inserted in two separate sessions 3-6 months apart to acquire proper osseointegration.
Digital scaffolds play an important role in tissue engineering and can be used to regenerate various dental tissues. The classical tissue engineering strategy involves isolating stem cells, growing them on a scaffold with growth factors, and implanting the construct. Scaffolds provide structure for cell migration, delivery of cells/growth factors, and reinforcement of defects. Ideal scaffolds are porous, biocompatible, biodegradable, and match tissue mechanical properties. Various natural and synthetic materials as well as fabrication techniques can be used to create scaffolds. Tissue engineering has applications in periodontology, endodontics, oral surgery, restorative dentistry, and prosthodontics.

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.

& loss of graft materialwww.indiandentalacademy.com
74. Sinus grafting was introduced by Tatum in 1970s
In early 1970s Tatum began to augment post. Maxilla
with autogenous rib bone to produce adequate vertical
bone for implant support
In 1974 he developed modified caldwell luc procedure
In 1975 he developed a lateral approach surgical
technique toelevate sinus membrane & place implant
simultaneously
From 1974 to 1979 primary material for sinus grafting
was autologous bone. In 1980 , Tatum introduced the use
of synthetic bone
www.indiandentalacademy.com
75. Initial publication on sinus grafting was by Boyne &

www.indiandentalacademy.com
82. In 1984 Misch organised a treatment approach for
posterior maxilla based upon the amount of bone
below the antrum
www.indiandentalacademy.com
83. in 1995 , Misch modified his classificationto include
the lateral dimension of sinus cavity to modify the
healing period protocol
Smaller width sinnus (0-10 mm) -: less healing time
Larger width(> 15 mm) -: more time

89. indicated when10-12 mm of vertical bone is present
Tatum originally developed the technique in 1970 &
Misch published it in 1987
Antral floor is elevated through implant osteotomy by
0-2mm
Compresses the bone below the antrum , causes a
greenstick fracture in the antral floor & slowly
elevates the unprepared bone & sinus membrane
over the broad based osteotome
Prosthetic treatment similar to SA1 after 4-6 months

93. Anesthesia
Maxillary branch of trigeminal nerve is blocked
Long acting anesthetic such as bupivacaine(0.5%) or
etidocaine(1.5%) is preferred
Incision line & reflection
Crest incision is made on the palatal aspect of maxilla
from tuberosity to one tooth anterior to the anterior wall of
sinus
Vertical relief incision is made on the distal to enhance
access to max. tuberosity
Anterior incision is made at least 10 mm ant to the ant
wall of sinus
www.indiandentalacademy.com
94. Access window
Tatum access window is 2-5 mm above the antral

96. Flat ended metal punch & mallet is used to lightly
tap & green stick fracture the access window from
the lateral wall of maxilla
www.indiandentalacademy.com
97. Sharp blade of the curette is placed against the inner
wall of bone & is used to scrape off the sinus
membrane from the bone

sinus floor & crest of residual ridge
www.indiandentalacademy.com
102. Lateral wall approach is performed for sinus graft as
in SA 3 procedure
Medial wall of sinus membrane is elevated at least
16 mm fron the crest so that adequate height is
available for implant placement
If bone from max tuberosity is not enough ,
additional bone may be harvested from above the
roots of maxillary premolars or mandibular
ascending ramus www.indiandentalacademy.com

106. Convenient surgical access
No cutaneous scar
Patients report minimal donor site discomfort
Inherent biological benefits attributable to the
embryologic origin of donor bone
Experimental evidence shows that grafts from
membranous bone show less resorption than
endochondral bone. Maxilla & body of mandible are
membranous bones
J Oral Maxillofacial surgery 1996 : 54 (15-
20)
www.indiandentalacademy.com
107. Early revascularization of membranous bone grafts
helps in improved maintenance of graft volume
Bone from the maxillofacial skeleton contains
increased concentration of growth factors & BMPs
Plastic reconstructive surgery 1994 : 93 ( 732 –
738)
Improved survival of craniofacial bone grafts is
caused by their 3-D structure
J oral maxillofacial surg 1996 :54 (15 –
20 )
Mand. Cortical bone grafts show little volume loss &
show good incorporation at short healing times
www.indiandentalacademy.com
108. In 1992 Misch et al used mandibular symphysis &
ramus bone grafts for endosteal dental implants
J of oral maxillofacial implants 1992 : 7 ( 360 –
366 )
www.indiandentalacademy.com
110. Easier graft harvest
Less post – op discomfort
Less neurosensory complications
Less incision line opening
Less anesthesia reqd.
More profound LA with fewer drugs
Less concern of changes in facial
morphology
www.indiandentalacademy.com
111. Less width & length of bone
www.indiandentalacademy.com
112. Slight curved triangular shape in the midlineis often
well suited for re-establishing the arch form in
maxillary anterior ridges
Average interforaminal distance is greater than 4 cm
, so more bone volume is available
www.indiandentalacademy.com
113. Width & height requirements for augmentation
Mandibular symphysis : when more than 4 cm of
bone is desired ( C-w bone volume )
Mandibular ramus :when graft width is less than 4
mm ( div. B to B-w bone volume )
Mandibular symphysis along with its cortical inferior
border : when an augmentation for height is required
www.indiandentalacademy.com
114. Location of the host or recepient site
Recepient site
• Anterior mandible
• Posterior mandible
• maxilla
Donor site
• Symphysis
• Ramus
• ramus

122. Presence or absence of molars
Width & height of external oblique ridge in the body
of the mandible
Distance from the external oblique ridge & ramus to
the inferior alveolar nerve
Width of posterior ramus is evaluated using
reformatted CT image
www.indiandentalacademy.com
123. As a result of these
variables a rectangular
piece of cortical bone
about 3 – 6 mm in
thickness may be
harvested from the
ramus. Length may
range from 1 – 3.5 cm &
height usually is not
greater than 1 cm
www.indiandentalacademy.com
124. After harvesting graft may be stored in sterile saline
or immediately fixed to the recepient site
Trabecular surface of the graft should be in contact
with decorticated surface of the host bone
Donor block & recepient site contouring
2 or more fixation screw sites should be prepared for
each bone block
www.indiandentalacademy.com
125. Holes in the donor
block should be
slightly larger than the
outer diameter of
fixation screws but
smaller in diameter
than the head of the
screw
www.indiandentalacademy.com
126. A high speed lindemann bur or carbides are then
used to recontour the block bone & smmothen any
sharp edges or corner after it is fixed
Barrier membrane
Not routinely used with cortical block bone grafts
Indicated if more particulate or trabecular bone is
used
Indicated if block graft is inadequate to fill the entire
space
www.indiandentalacademy.com
127. Flap should be approximated &
sutures placed such that there is no
incision line tension or tissue ischemia
www.indiandentalacademy.com
128. Stop smoking at least 3 days before surgery &
until incision line has healed
Removeble soft tissue prosthesis should not be
worn
Confirm to regular post operative follow up
www.indiandentalacademy.com
131. Advantages
Large volumeouter portion of the graft may be
primarily cortical with major portion of trabecular
bone underneath
Volume of the bone harvested permits contouring of
2/3 of the mandible or maxilla or filling a large bony
defect
Relative ease of access & harvesting
www.indiandentalacademy.com
132. Disadvantages
Rapid bone resorption of 30 – 90 % has been
reported when conventional dentures are placed on
top of the reconstruction
Curtis et al JPD 1987 ; 57 (73-
78)
• post operative pain & gait disturbances
www.indiandentalacademy.com
134. Proximal tibial metaphysis provides an excellent
source of trabecular bone
Primarily used with with BM & GBR procedure
because major part of the harvest is trabecular in
nature
www.indiandentalacademy.com
135. Disadvantages
Contraindicated in adolescents & children coz
disruption of epiphyseal growth centre my occur
Fat content of the marrow is sometimes greater than
that found in the ilium
www.indiandentalacademy.com
136. Complications
Hematoma

138. Advantages
Maintains normal physiologic function
Simultaneous placement of implants with
microvascular bone flap reconstruction has shown
an approximately 80% success rateusing Ti implants
with a short follow up
www.indiandentalacademy.com
139. Disadvantages
