Dental implants are artificial roots, usually made of titanium, that are surgically placed into the jawbone to support replacement teeth. Implants can replace one or more missing teeth and provide support for dentures or bridges. The implant surgery involves drilling into the jawbone, placing the implant, and allowing time for osseointegration where the implant fuses with surrounding bone.

This document summarizes a new porous titanium dental implant technology called Ti FoamTM that is created using nanotechnology. It has the following key advantages over other dental implants: 1) Its porous structure mimics bone to facilitate rapid bone growth; 2) Growth enhancers and antibiotics embedded in the material promote even faster healing within days rather than months; 3) The expanded surface area of the porous material allows it to bond twice as much bone. This positioning opens opportunities in a large and growing $3.5 billion global dental implant market. The technology has completed development and testing and seeks $1.5 million in initial funding to commercialize the product.
Dental implants involve reconstructing missing teeth and supporting structures with natural or synthetic substitutes, preserving residual bone and providing excellent aesthetics, though the procedure is expensive, requires surgery, takes time, and is technically complex. There are various types of implants that can be used, made from materials like titanium, zirconium, and hydroxyapatite ceramic. Threaded implants in particular have demonstrated maintaining steady bone response compared to cylindrical implants. Surface roughness, thread pitch, and bone quality also impact osseointegration and implant success.

Baic dental implantology and Implant related surgery"stat of the art"Cairo university
Titanium and its alloys are commonly used for dental implants due to their excellent biocompatibility properties. Dental implants osseointegrate with bone through a process that begins with ion absorption by the titanium oxide layer and leads to bone apposition at the implant interface over 3-5 months. Primary stability from implant design and bone quality and secondary stability from bone remodeling are important for successful osseointegration. Ridge augmentation techniques like grafting and sinus lifts can address bone deficiencies to allow for proper implant placement and loading. While failures can occur from surgical or post-operative issues, maintaining oral hygiene and proper implant selection and loading are keys to long-term success.
Applied anatomy,physiology for dental implantsAnil Goud
understanding of basic anatomy and physiology is most important in Dental implants planning. this ppt. will give in depth knowledge of anatomy physiology of oral cavity
The document describes the anatomy of the head and neck region, specifically focusing on the oral cavity and pharynx. It is divided into several sections that describe: 1) the oral cavity including the oral vestibule and oral cavity proper, 2) the floor of the mouth including structures like the frenulum and papillae, 3) the tongue including its muscles and blood supply, 4) the palate including the hard and soft palate, and 5) the pharynx including its walls, muscles like the constrictors, and structures like the tonsils. Each section provides details on the boundaries, structures, and relations of the different anatomical regions within the head and neck.
This document provides an overview of a lecture on head and neck anatomy presented by John Moore. It includes a list of key structures of the head and neck region and provides descriptions and images of muscles, bones, blood vessels, nerves, glands and other anatomical features of the head and neck. The purpose is to familiarize students with the basic anatomy of this region for an introductory anatomy course.
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 describes the anatomy of the lips, oral cavity, tongue, and associated structures. It discusses the layers of the lips, boundaries and divisions of the oral cavity, glands and ducts associated with the mouth, muscles of the oral region, and papillae and taste buds of the tongue.

This document discusses the anatomy and histology of structures that support complete dentures. It describes the key stress bearing and peripheral/sealing areas that dentures rely on for support. The residual ridge and hard palate are identified as primary stress bearing regions due to their thick, keratinized mucosa firmly attached to underlying bone. In contrast, peripheral areas like the vestibule and lips have thin, movable mucosa with loose tissue unsuitable for supporting denture forces. A thorough understanding of oral tissues is essential for dentists to design complete dentures that respect the anatomical and physiological limitations of the edentulous mouth.
This document describes important anatomical landmarks in the edentulous maxilla and mandible that are relevant to complete denture prosthodontics. It defines relief areas, support areas, and stress bearing areas. For the maxilla, it identifies landmarks like the labial and buccal frenums, labial and buccal vestibules, alveolar ridges, maxillary tuberosity, incisive papilla, palatine rugae, torus palatinus, midpalatine raphe, fovea palatini, hamular notch, vibrating line, and posterior palatal seal area. For the mandible, it identifies landmarks like the labial and buccal frenums
ANATOMICAL LANDMARKS IN MAXILLA and it's importanceSrustishastri
This document discusses important anatomical landmarks in the maxilla that are relevant for maxillary dentures. It outlines primary and secondary stress bearing areas like the tuberosities and hard palate. It also describes relief areas like the incisive papilla and torus palatinus that need space provided in the denture base. Limiting structures such as the labial and buccal frenums and vestibules that impact denture border extensions are examined. The hamular notch, fovea palatinae and vibrating lines which help locate the posterior denture border are defined.
The soft tissues along the junction of hard and soft palate on which pressure within the physiological limits of tissues can be applied by the denture to aid in retention of the denture.
This document provides an overview of important anatomical landmarks in the maxilla for complete dentures. It discusses extraoral landmarks like the vermilion border and nasolabial angle. Intraoral landmarks include the labial and buccal frenums, vestibules, hamular notch, and fovea palatinae. The maxilla has primary and secondary stress bearing areas, as well as relief areas that should not be loaded. Landmarks help determine the limits and extensions of denture borders to maximize retention while avoiding interferences with underlying structures.

Conclusion
Bibliography
www.indiandentalacademy.com
3. MUCOUS MEMBRANE
It is composed of mucosa and sub mucosa.
The mucosa is formed by stratified squamous
epithelium, which often is keratinised and a
subjacent narrow layer of connective tissue
known as the laminapropria.
In the edentulous person the mucosa covering
the ridge and the palate is called the masticatory
mucosa
www.indiandentalacademy.com
4. The mucosa varies in its thickness and density ,
thinnest covering the midpalatine raphe next
thinnest being the mucosa covering the ridges
and thickest covering the blood vessels and
nerves of the lateral aspects of the palate.
www.indiandentalacademy.com
5. Residual ridge
The bone that is left behind after all the teeth are
removed and after a disease or surgery affected.
First it was considered to be the primary stress
bearing area but it is looked upon the secondary
stress bearing area because of the fact that bone
is subjected to continuous resorption though it
decreases as the span of the edentulousness
increases.
www.indiandentalacademy.com
6. The ridge varies greatly in size and shape and its
ultimate form is dependent on the following
factors:-
Original size, shape and calcification of the bone .
Size of the natural teeth
General health of the patient.
Forces exerted by the surrounding
www.indiandentalacademy.com
7. Musculature.
Amount of the bone loss due to the
disease
before extraction
Duration of edentulousness and the rate
of resorption
Effect of previous prosthesis
www.indiandentalacademy.com
8. Hard palate
The ultimate support for the maxillary
denture is the hard palate
The two palatine process of the maxilla
fuse together to form the hard palate at the
mid palatine suture.
It is covered by the mucosa of varying
thickness.
www.indiandentalacademy.com
9. In the region of the midpalatine suture the sub
mucosa is very thin and it has to be relieved .
Quite often in the mid palatine suture, a
hyperplastic growth of bone is seen.
This intervenes with the stability of the
denture, this called as torus palatinus.
Steps should be taken to obtain considerable
relief by using the special impression
techniques, mechanical relief or by the last
resort, by its surgical excision.
www.indiandentalacademy.com
10. Rugae
In the area of the rugae the palate is set at
an angle to the ridge and rather thinly
covered by the soft tissue.
This is considered to be the secondary
stress bearing area
Rugae are said to be associated with the
sense of taste and the function of speech
They assist the tongue to absorb via its
papillae.
www.indiandentalacademy.com
11. They also enable the tongue to form a
perfect seal when it is pressed against the
palate in making the linguo palatal
constant stops of speech.
Rugae should not be displaced,otherwise
the rebounding may dislodge the denture.
They provide anteroposterior resistance to
movement of the denture and increased
surface area helps in retention.
www.indiandentalacademy.com
12. Maxillary tuberosity
It is a bony prominence situated at the posterior
aspect of alveolar ridge.
A broad well rounded tuberosity of sufficient
height is favorable.
Large maxillary tuberosities bounded by deep
sulci offer very satisfactory resistance to the
lateral movement of the denture.
www.indiandentalacademy.com
13. Tuberosities sometimes exhibit buccal undercuts ,
if it is unilateral it can be utilized for the retention.
If excess hyperplastic tissue is present it should be
surgically corrected.
www.indiandentalacademy.com
14. Incisivepapilla
It is a thick fibrous connective tissue covering the
incisive foramen.
It is located on the line immediately behind and
between the central incissors.
Relief for the papilla should be provided to prevent
any possible interferences with the blood and nerve
supply.
Clinical significance:-
it helps to determine the midline.
it determines the position of the upper anteriors.
it helps to assess the amount of resorption
because it does not change the position.
www.indiandentalacademy.com
15. The horizontal distance between the
perpendicular line from incisive papilla to labial
surfaces of incisors should be about 8-10mm.
It helps in selecting the size of the upper
anteriors i.e the horizontal line drawn cutting
the papilla and extending over the land surface
should coincide with the position of the upper
canine tooth.
It helps in determing the vertical dimension of
occlusion i.e distance between the incisal edge
and the papilla should be 4 mm.
www.indiandentalacademy.com
16. Zygomatic process
It is also called as malar process.
It is located opposite the first molar region.
It is prominent in the long span edentulous
people.
In some cases it requires relief over this
area to aid in retention and prevent
soreness of the underlying tissues.
www.indiandentalacademy.com
17. Pterygomandibular raphe
It originates from the hamular process and
in close proximity to the distal edge of the
upper denture.
If this edge is over extended it will impinge
on the fold of the soft tissue which is
elevated when the mouth is open and the
raphe becomes tensed.
This causes inflammation and often
reported as soreness of the throat or the
denture flips downwards each time when
patient opens the mouth.
www.indiandentalacademy.com
18. Sharp spiny process
Frequently there are sharp spiny process
on the maxillary and palatine bones that
are deeply covered with the soft tissue.
In patients with the considerable
resorption of the ridge these spines
irritates the soft tissues left between them
and the denture base.
www.indiandentalacademy.com
19. Labial Frenum
It is a fan shaped fibrous pack covered by mucus
membrane that extends from the inner aspect of upper
lip and attached to the labial aspect of residual ridge.
It is usually single and does not contain muscle fibres
It has to be relieved while making impression in order
to prevent dislodgement of the denture and to prevent
Ulceration and the upper lip will be pushed away from
the functional depth and there will be more visibility of
the teeth
www.indiandentalacademy.com
20. It is relieved by making up and downward
movements of upper lip.It is seen as a V shaped
notch in the impression
www.indiandentalacademy.com
21. Labial Vestibule
Labial Vestibule is divided in to left and right by
the labial frenum
The mucous membrane lining the labial vestibule
has a relatively thin mucosa with a epithelium that
is non keratinised
The depth of the labial sulcus depends on
-height of the alveolar ridge
-Mobility and tension of the surrounding
muscles
The labial sulcus is relieved by functional moulding of
the upper lip
www.indiandentalacademy.com
22. Over extension of labial flange of the denture
causes ulceration or instability of the denture
The thickness of the flange provides stability
and peripheral seal
www.indiandentalacademy.com
23. Buccal frenum
It’s a fold of mucous membrane overlying the muscles
near the premolar region
It may be single or multiple. It divides the labial and
buccal vestibules.
It requires more clearance for its action than the labial
frenum
It moves mesially,buccaly and vertically
Orbicularis oris- Mesial movement
Buccinator-Buccal movement
Levator angulioris and Canninus –Vertical movement
www.indiandentalacademy.com
24. Buccal Vestibule
It lies opposite the tuberosity and extends from
the buccal frenum to the Hamular notch
The size of the vestibule varies with the
contraction of the Buccinator muscle,position of
the mandible,amount of the bone loss from the
maxilla
Compare to the labial flange ,buccal flange has
less interferences and so provides maximum
retention
www.indiandentalacademy.com
25. Width of the buccal flange is determined by
making side ward movement of the mandible and
during this movement the coronoid process will
be closed to the tuberosity
Excessive thickness of buccal flange will
displace the denture when the patient opens the
mouth wide
www.indiandentalacademy.com
26. Pterygomaxillary notch
It’s a bony depression between tuberosity
and hamulus of the medial pterygoid plate
This forms the distal limit of the upper
denture
It is covered by the mucosa of sufficient
thickness and can be compressed to
achieve peripheral seal
Over extension will lead to the pain and
dislodgment of the denture
www.indiandentalacademy.com
27. Fovea palatine
These are the depressions or indentations
situated on the soft palate on the either
side of the midline
It helps to determine the midline and
positioning of the posterior border
These are the ductal openings in to which
ducts of other palatal mucous glands drain
www.indiandentalacademy.com
28. Posterior palatal seal
It is defined as the soft tissues along the
junction of the hard and soft palates on
which pressure with in the physiologic
limits of the tissues can be applied by a
denture to aid in the retention of the
denture.
Its significance is
-To maintain contact with the anterior
portion of the soft palate during the
functional movements,therefore the
primary purpose of it is retention of the
denture.
www.indiandentalacademy.com
29. The proper placement of it will reduces the
patient awareness of this area with subsequent
reduction in the Gag reflex.
It reduces the food accumulation beneath the
posterior aspect of the denture
It reduces the patient discomfort when contact
occurs between the dorsum of the tongue and
the posterior end of the denture base
As it lies in close approximation to the soft
palatal tissue, it compensates for the volumetric
shrinkage that occurs during polymerization of
Methyl Methacrylate resin
www.indiandentalacademy.com
30. The correct placement of the seal will not
impinge up on the non displaceable tissues of
hard palate and it will not limit the muscular
movements of the soft palate
It will create a partial vacuum beneath the
maxillary denture. It is activated only when
horizontal or tipping forces are directed against
denture base
www.indiandentalacademy.com
31. Anterior vibrating line
It is an imaginary line located at the junction of
the attached tissues overlying the hard palate
and the movable tissues of immediately
adjacent soft palate
One way to locate the line is to ask the patient
perform the Valsalva maneuver which requires
that both nostrils be held firmly while the
patient blows gently through the nose
It can also be approximated by visualisig the
area while instructing the patient to say ”AH”
with short vigorous bursts
www.indiandentalacademy.com
32. Due to the projection of the posterior nasal
spine, this line is not a straight line between both
Hamular processes
It is always on soft palatal tissues
www.indiandentalacademy.com
33. Posterior vibrating line
It is an imaginary line at the junction of the
aponeurosis of the Tensorveli palatina muscle
and the muscular portion of the soft palate.
It represents the demarcation between that part
of the soft palate that has limited or shallow
movement during function and the remainder of
the soft palate that is markedly displaced during
functional movements
www.indiandentalacademy.com
34. It is visualised by instructing the patient to say
“AH” in short bursts in a normal un exaggerated
fashion.
It marks the most distal extension of the denture
base.
www.indiandentalacademy.com
35. The rational for the placement of seal in the
impression tray is as follows
1).To establish positive contact posteriorly to
prevent the final impression material from sliding
down the pharynx
2).To serve as a guide for positioning the
impression tray
3).To create slight displacement of the soft palate
4).To determine if adequate retention and seal of
the potential denture border is present
www.indiandentalacademy.com
36. Technique to determine posterior palatel seal
are
1).Conventional approach
2).Fluid wax technique
3).Arbitaryscraping of the master cast
www.indiandentalacademy.com
37. Crest of the residual ridge
The ridge is covered by fibrous connective
tissue.
The under lying bone is cancellous bone
which cannot take up the masticatory
loads.
the fibrous connective tissue closely
attached to the bone is favourable for
resisting applied forces, such as those
from a denture.
The mean denture bearing area is
13.95sq.cm www.indiandentalacademy.com
38. The buccal shelf or buccal flange
The area between the mandibular buccal
frenum and the anterior edge of the
masseter muscle is known as buccal shelf.
It is bound medially--crest of the residual
ridge.
Laterally--external oblique ridge.
Distally --retromolar pad.
The total width of the bony foundation in
this region becomes greater as alveolar
resorption continues.
www.indiandentalacademy.com
39. The mucous membrane covering this area is
loosely attached and less keratinised and has
thicker submucosal layer.Hence it may not be
histologically suitable to provide primary support
for the denture.
How ever the bone of the buccal shelf and the
fact that it lies at right angles to the vertical
occlusal forces makes it suitable primary stress
bearing area for the denture.
The inferior part of the buccinator muscle is
attached to the buccal shelf and its fibers are
found in the submucosa immediately overlying
the bone
www.indiandentalacademy.com
40. Mylohyoid ridge
Soft tissue usually hides the sharpness of the
mylohyoid ridge.
The shape and inclination of the ridge vary
greatly among the edentulous people.
Anteriorly the mylohyoid muscle is attached and
lies close to the inferior border of the mandible.
posteriorly following resorption, it often lies
flush with the superior surface of the ridge.
www.indiandentalacademy.com
41. The mucous membrane over a sharp or
irregular mylohyoid ridge will be easily
traumatized by the denture base.
The area under the ridge is an undercut.
www.indiandentalacademy.com
42. Mental foramen
Severe resorption of bone results in
mental foramen lying close to or at the
crest of the ridge results in compression
of the mental nerves and blood vessels,if
relief is not provided in the denture base.
Pressure on the mental nerve can cause
numbness of the lower lip.
www.indiandentalacademy.com
43. Genial Tubercles
They usually lie well away from the crest of
the ridge
However with the resorption the genial
tubercles become increasingly prominent
www.indiandentalacademy.com
44. Torus mandibularis
This is a bony prominence usually found
bilaterally and lingually near the first and
second premolars mid way between the
soft tissues of the floor of the mouth and
the crest of the alveolar ridge
In the edentulous mouth where
considerable resorption takes place, the
superior border of the torus may be flush
with crest of the ridge
www.indiandentalacademy.com
45. It is covered by extremely thin layer of mucous
membrane which often needs to be corrected
surgically as it cannot be relieved with in the
denture with out breaking the border seal
www.indiandentalacademy.com
46. External oblique line
It is a ridge of the dense bone extending
from just above the mental foramen in a
superior and distal direction to become
continuous with the anterior border of the
ramus
It is an anatomical guide for the lateral
termination of the buccal flange of the
denture
www.indiandentalacademy.com
47. Buccal & Labial borders
The labial frenum contains a band of
fibrous connective tissue that helps attach
the orbicularis oris
Therefore the frenum is quite sensitive and
active and must be carefully fitted to
maintain a seal without causing soreness
www.indiandentalacademy.com
48. Buccal Frenum
It connects as a continuous band through the
modiolus at the corner of the mouth to the
buccal frenum in the maxilla
This fibrous and muscular tissues pull actively
across the denture borders, polished surfaces
and teeth
Therefore denture should extend less in this
region and the impression must be functionally
trimmed to have the maximum seal and yet not
displace the denture when the lip is moved
www.indiandentalacademy.com
49. Labial Vestibule
It runs from the buccal to the labial frenum
The mentalis muscle is particularly active
muscle in this region
It contains a band of fibrous connective
tissue that helps attach the orbicularis oris
muscle
www.indiandentalacademy.com
50. Buccal vestibule
It extends posterior from the buccal frenum to the outside
back corner of the retro molar pad
The extent of the vestibule is influenced by buccinator
muscle anteriorly to the pterygomandibular raphe
posteriorly its lower fibres attached to the buccal shelf and
external oblique ridge
www.indiandentalacademy.com
51. The flange which starts immediately posterior to the
frenum swings wide in o the cheek and it is nearly right
angle o the biting force.
The impression is always widest in this region
The disto buccal border at the end of the vestibule
must converge rapidly to avoid displacement by the
contracting masseter muscle whose anterior fibers run
outside and behind the buccinator muscle in this
region
www.indiandentalacademy.com
52. Retro Molar pad
It is triangular soft pad of tissues at the
digital end of he lower ridge
Its mucosa is composed of a thin non
keratinized epithelium and in addition its
sub mucosa contains glandular tissue and
fibers of the buccinator and superior
constrictor muscles,the
pterygomandibular raphe and the terminal
part of the tendon of the temporalis
muscle
www.indiandentalacademy.com
53. The action of these muscles limits the extent of
the denture and prevents placement of extra
pressure on the distal part of the retro molar
pad during the impression procedures
www.indiandentalacademy.com
54. Mylohyoid muscle
The floor of the month is formed by this
muscle which arises from the whole length
of the Mylohyoid ridge
This ridge is sharp and distinct in the
molar region and becomes almost
indiscernible anteriorly
Medially the fibres join those from the
mylohoid muscle of the opposite side and
posteriorly they continue to the hyoid base
www.indiandentalacademy.com
55. The muscle lies deep to the sub lingual
gland and other structures in the anterior
region and so does not affect the denture
border except indirectly
The posterior part of h muscle in the molar
region affects the lingual impression border
in swallowing and in moving the tongue
Extension of the lingual flange under this
ridge cannot be tolerated in function
because it will interfere with the action of he
mylohyoid muscle when it contract will
displace the denture causing soreness
www.indiandentalacademy.com
56. An extension of the lingual flange well beyond
the palpable position of the ridge,but not in to
the undercut has other advantages.
The lack of the direct pressure on the sharp
edge of the ridge will eliminate the possible
source of discomfort.

57. Retromylohyoid fossa
It is the area posterior to the mylohyoid
muscle
As the lingual flange moves in to this
fossa.It ceases to be influenced by the
action of the mylohyoid muscle and so can
move back towards the body of the
mandible producing the typical “S” curve
of the lingual flange
www.indiandentalacademy.com
58. It is bounded by the retromylohyoid
curtain
The postero lateral portion of the curtain
overlies the superior constrictor
muscle,and postero medial portion covers
the palatoglossal muscle plus the lateral
surface of the tongue
The inferior wall overlies the sub
mandibular gland,which fills the gap
between the superior constrictor muscle
and the most distal attachment of the
mylohyoid muscle.
www.indiandentalacademy.com
59. The denture border should extend posteriorly to
contact the curtain when the tip of the tongue is
placed against the front part of the upper ridge.
Protrusion of the tongue causes the curtain to
move forward.
www.indiandentalacademy.com
60. Sublingual gland region
In the premolar region the sub lingual
gland rest above the mylohyoid
muscle
When the floor of the mouth is raised
the gland comes quite close to the
crest of the ridge and reduces the
vertical space available for the
extension of the flange in the anterior
part of the mouth
www.indiandentalacademy.com
61. This can be avoided by shaping this part of the
flange of the tray to slope inward, toward the
tongue and making the final impression with low
viscosity impression material
www.indiandentalacademy.com
62. Alveololingual sulcus
It is the space between the ridge and tongue
extending from the lingual frenum to the retro
mylohyoid curtain
The anterior region:
This extends from the lingual frenum back to
where the mylohyoid ridge curves down below
the level of the sulcus
www.indiandentalacademy.com
63. Premylohyoid fossa is palpated and a
corresponding eminence seen on the
impressions
The lingual border in this region should
extend down to make contact with the
mucus membrane, floor of the mouth
when the tip of the tongue touches the
upper incisors
The flange will be shorter than the
posterior flange
www.indiandentalacademy.com
64. Middle region:
This region extends from pre mylohyoid
fossa to the distal end of the mylohyoid
ridge,curving medially from the body of the
mandible
Posterior region:
Flange passes in to the retrohyoid fossa and
so mylohyoid muscle does not influence
the denture border in this region
www.indiandentalacademy.com
65. Conclusion
The denture bearing areas not only support
the dentures but have a direct bearing on
the impression making procedures, the
position of teeth and the contours of the
finished denture base.
Thus thorough knowledge of the anatomy
and physiology of the supporting structures
is essential for the success of the
prosthesis
