Introduction. The differences in the supporting structure of the implant make them more susceptible to inflammation and bone
loss when plaque accumulates as compared to the teeth. Therefore, a comprehensive maintenance protocol should be followed
to ensure the longevity of the implant. Material and Method. A research to provide scientific evidence supporting the feasibility
of various implant care methods was carried out using various online resources to retrieve relevant studies published since 1985.
Results.The electronic search yielded 708 titles, out of which a total of 42 articles were considered appropriate and finally included
for the preparation of this review article. Discussion. A typicalmaintenance visit for patients with dental implants should last 1 hour
and should be scheduled every 3 months to evaluate any changes in their oral and general history. It is essential to have a proper
instrument selection to prevent damage to the implant surface and trauma to the peri-implant tissues. Conclusion. As the number
of patients opting for dental implants is increasing, it becomes increasingly essential to know the differences between natural teeth
and implant care and accept the challenges of maintaining these restorations.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

1. INDIAN DENTAL ACADEMY
Leader in continuing dental education
www.indiandentalacademy.com
www.indiandentalacademy.com
2. Fluid Control and Soft tissue
Management
Introduction
1)Complete control
of the environment of the
operative site is essential during restorative
dental procedures (Fluid control procedures)
2)Control of the oral environment extends to
the gingiva surrounding the tooth being
restored(Gingival retraction procedures)
www.indiandentalacademy.com
3. Introduction……
)Sometimes it is necessary to permanently
alter the contours of the gingival tissue
around the teeth or edentulous ridge for
long lasting,better
restorations(Electrosurgery procedures)
www.indiandentalacademy.com
4. FLUID CONTROL
Need for removal of fluids varies and
depends on the task that is carried out:
1)Preparation of teeth – Large volumes of
water and saliva has to be removed
2)Cementation of Restoration & Impression
making - Smaller volumes of fluid has to be
removed .
Several types of attachment are used with Low
Volume (saliva ejector) or high volume vacuum
outlets to remove fluids
www.indiandentalacademy.com
5. RUBBER DAM
1)Most
effective of all isolation devices
2)It plays a major role in conservative dentistry
procedures
3)Limited role in the area of cast restorations
4)Can be used during tooth preparation for
inlays and onlays, for making impressions and
cementing the same.
5)In Impression making - not to be used with
polyvinylsiloxane material as it inhibits
polymerization www.indiandentalacademy.com
6. High volume Vacuum
1)Extremely useful
during the preparation
phase.
2)Excellent Lip Retractor while the operator
uses a mirror to retract and protect the
tongue
3)Not useful while making impressions or
cementation phases
www.indiandentalacademy.com
7. Saliva Ejector
1)Adjunct to high Volume evacuation – but can
be used alone for the maxillary arch
2)Placed in the corner of the mouth ,opposite the
quadrant being operated,and the patients head is
turned towards it.
3)Very effectively used in the maxillary arch for
impressions and cementation
4)Can be used on the mandibular arch also.
www.indiandentalacademy.com
8. Svedopter
1)For isolation and evacuation of the mandibular
teeth,the metal saliva ejector with attached
tongue deflector is excellent.
2)Most effective when used with the patient in
upright position.
3)Access to the lingual surfaces of the
mandibular teeth is a drawback
4)Presence of mandibular tori precludes its use.
5)The anterior part of the Svedopter should be
placed in the incisor region,with the tubing
under the patients arm
www.indiandentalacademy.com
9. Antisialagogues
1)Drugs used to create a dry zone in the oral cavity,
Methantheline bromide (Banthine)
Propanthaline bromide (Probanthine)
(These are anticholinergics that act on the smooth
muscles of the GIT,Urinary and biliary
tracts,producing dry mouth as a side effect)
Dosage (50mg of Banthine or
15mg of Probanthine – 1 hr before the appt)
www.indiandentalacademy.com
11.
Drug interactions
1)Potentiated by antihistamines
,tranquilizers, and narcotic analgesics
Alternatives
1)Propantheline- 2 to 6 mg injected
intraorally
2)Clonidine hydrochloride – 0.2mg (an hour
before appt
www.indiandentalacademy.com
12. FINISH LINE EXPOSURE
1.Tooth preparations in the presence of
untreated gingivitis makes task more
difficult and compromises chances for
success.
2.Marginal fit of a restoration is essential in
preventing recurrent caries and gingival
irritation
Hence finish line of the preparation
must be reproduced in the impression
www.indiandentalacademy.com
13. Techniques for exposure of finish line
1)Complete impression is complicated when
some or all of the finish line lies at or apical to
the crest of the free gingiva
2)In such cases finish line of a prep must be
temporarily exposed to insure reproduction of
the entire preparation
3)Methods employed are :
a)mechanical
b)Chemicomechanical
c)surgical – 1)rotary curettage
2)electro surgery
www.indiandentalacademy.com
14. Mechanical Methods
1)Physically displacing the gingiva was one of the method
for finish line exposure
2)Copper band or tube can serve as a means of carrying the
impression material as well as a mechanism for displacing
the gingiva to insure the capture of the finish line
3)Copper bands are especially useful when several teeth are
have been prepared
4)rubber dam can also be used to expose finish
line,generally when limited number of teeth are being
restored and in which preparations do not have to be
extended too far subgingivally
www.indiandentalacademy.com
16.
Epinephrine
1)causes local vasoconstriction ,which
results in transitory gingival shrinkage.
2)should not be used on patients taking
Rauwolfia compounds,ganglionic blockers
or epinephrine potentiating drugs
www.indiandentalacademy.com
17.
Alum
Used in patients with cardiovascular
diseases or hyperthyroidism or a known
hypersensitivity to adrenaline.
www.indiandentalacademy.com
18. Gingival Retraction -Procedure
1)2 inch piece of
retraction cord is
cut off
2)Cord is twisted to
make it as ight and
as small as possible
www.indiandentalacademy.com
19. 3)Loop of retraction
cord is formed around
the tooth and and held
taut with the thumb
and the forefinger
4)Placement is started
by pushing the cord
into the sulcus on the
mesial surface.It is also
slightly tacked into the
distal crevice to hold
the cord in position
while
www.indiandentalacademy.com it is being placed
20.
5)As the cord is placed
subgingivally the
instrument must be
pushed slightly toward
the area already tucked
into place.If the force
of the instrument is
directed away from the
area previously
packed,the already
packed cord will be
pulled out
www.indiandentalacademy.com
21.
6)Occasionally it is
necessary to hold the
cord with one
instrument while
packing with the
second
7)Instrument is
slightly angled
towards the root to
facilitate the
sublingual placement
of the cord
www.indiandentalacademy.com
22.
8)If the instrument is
held parallel to the
long axis of the
tooth,the cord will be
pushed against the
wall of the gingival
crevice and it will
rebound
9)The excess cord is
cut off from the
mesial interproximal
area
www.indiandentalacademy.com
23.
10)The placement of the
distal end is finished
until it overlaps the mesial .
It is made sure that the
force of the instrument is
directed toward the cord
previously packed
(To the distal in this case)
www.indiandentalacademy.com
24.
Placement of the cord in the sulcus
A)Correct
B)Incorrect
www.indiandentalacademy.com
25. Usage of ferric Sulphate Solution
Cord removal is done after made damp
If bleeding persists,Electro coagulation and ferric
sulphate are sometimes effective in stopping
persistent bleeding
If ferric sulfate is used as a chemical,soak a plain
knitted cord in it and place the cord in the
gingival sulcus
After 3 minutes, remove the cord
Then 1 cc special syringe is loaded with the
stringent chemical and a special fibrous tip is
used to rub or burnish cut sulcular tissue until all
bleeding stops. www.indiandentalacademy.com
26. Rotary Curettage
1)It is a troughing technique
2)Purpose is to produce limited removal of
epithelial tissue in the sulcus while a
chamfer finish line is being created in the
tooth structure
3)Must be done only on
healthy,inflammation free tissue to avoid
tissue shrinkage that occurs when diseased
tissue heals
www.indiandentalacademy.com
27.
1)A shoulder is formed at the level of the gingival
crest prior to rotary curettage
2)A Torpedo tipped diamond bur simultaneously
forms a chamfer finish line and removes the
epithelial lining of the gingival sulcus
3)A cord is placed in the troughed sulcus for
hemostasis
www.indiandentalacademy.com
28. Electrosurgery
1)Employed in situations where gingiva cannot be
handled with retraction cord alone.
(Ex – Areas of inflammatiion and
granulation tissue around a tooth,as a result of
overhangs or previous restoration or caries itself
2)Generally recommended for enlargement of
gingival sulcus and control of heamorrhage
3)Employs a high frequency electrical current of
1.0 MHz (Million Cycles per second) or more to
www.indiandentalacademy.com
produce controlled tissue destruction
29.
1)Typical electrosurgery
unit with active electrode
(A) and ground electrode
(B)
2)Five commonly used
electrodes –
a)coagulating
b)diamond loop
c)round loop
d)small straight
e)small loop
www.indiandentalacademy.com
30. Electro surgery – Mode of Action
1)Unit generates heat in a way similar to
microwave heating oven or a diathermy
machine
2)Current flows from a small cutting
electrode which produces a high current
density and rapid temperature rise at its
point of contact
3)Cells directly adjacent to to the electrode
are volatilizedwww.indiandentalacademy.com
at this temperature
32. Electrosurgery - Contraindications
1)Patients with Cardiac Pacemakers
2)Should not be used in the presence of
inflammable agents(Since generates sparks)
– Hence use of topical anesthetic such as
ethyl chloride and other flammable aerosols
should be strictly avoided when electro
surgery is used
www.indiandentalacademy.com
33. Electro surgery Technique
1)Anesthesia is verified in the site of surgery
2)Aromatic oil (Peppermint) is placed on the
vermillion of the upper lip to (For masking
unpleasant smell arising during tissue cutting
3)Connections of the unit are checked
4)Cutting electrode should be applied with light
pressure only
5)Strokes should be quick and deft
6)Electrode should be kept moving and no stroke
should be repeated immediately,smoothly
without tissue charring
www.indiandentalacademy.com
34. Contd……
7)Moist tissue will cut best
8)High volume vacuum tip(Plastic tip used
– to avoid burns when contact is made with
electrode) is used to draw off unpleasant
odors generated
9)Wooden tongue depressor is used rather
than normal mouth mirror
10)Frequently fragments are cleaned from
tip with an alcohol soaked sponge
www.indiandentalacademy.com
37.
Debris are cleaned
from the enlarged
sulcus with
hydrogen peroxide
on a cotton pellet
www.indiandentalacademy.com
38. Removal of Edentulous Cuff
1.Remnants of interdental
papilla adjacent to an
edentulous space will form a
hypertrophic roll or cuff –
hence fabricating a pontic
with cleanable embrasures
and strong connectors
2.A Large Loop electrode is
used for removing large roll
www.indiandentalacademy.com
of hypertrophied tissue
39. Crown Lengthening procedure
1)If there is a sufficiently wide band of
attached gingiva surrounding a tooth,its
removal can be accomplished with a
gingivectomy using a diamond electrode
2)Periodontal dressing is placed after
surgery
3)Lengthened tooth offers better retention
for any crown placed on it ,with the margin
placement in an area of the tooth more
accessible for cleaning
www.indiandentalacademy.com
40. Impressions
Impression – Definition
A negative likeness or copy in reverse
of the surface of an object;an imprint of the
teeth and adjacent structures for use in
dentistry
www.indiandentalacademy.com
42. Requirements of a good
impression
1.Exact duplication of the prepared tooth(all
of the preparation and enough undercut
tooth surface beyond the preparation –For
being certain about the location and
configuration of the finish line
www.indiandentalacademy.com
43. Requirements……..
2.Teeth and tissue adjacent to the prepared
tooth must be accurately reproduced to
permit accurate articulation of the cast and
to allow proper contouring of the restoration
3.Impression of the preparation must be
bubble free especially in the area of the
finish line
www.indiandentalacademy.com
45. Reversible hydrocolloid
1)Packaged as a semisolid gel in polyethylene tubes
2)Liquefied in a hydrocolloid conditioner by placing it
in boiling water.
3)Liquid Sol is too hot for intraoral usage – Hence
cooled in two stages , storage and tempering.
4)Tray filled with tempered sol is place in the
mouth,cool tap water is circulated through double
walled jacket of the tray to complete the gelation
process.
5)when completely gelled,tray is removed from the
mouth
www.indiandentalacademy.com
46. 6)Distortion problem is inherent – since can
lose or absorb water (Syneresis or
imbibition),Hence have to be poured immd.
7)Conditioning Unit – Parts
1)Liquefying bath – loaded syringes
are boiled for 10 mins here
2)Storage bath – Stored at 150 F for 10
mins
3)Tempering bath – Tempered at 110 F
for 5 to 10 mins
www.indiandentalacademy.com
47. 8)Two impressions are usually made –
Sectional (Quadrant) impression for making
a die and a full arch impression for the
working cast.
9)Procedure ( Refer to OHP sheet ).
www.indiandentalacademy.com
48. Custom Resin trays
1.These trays are used in elastomeric impression
techniques because these materials are more
accurate in thin layers of 2 to 3 mm.
2)Tray preparation
a)Baseplate wax is softened in flame
b)Fold it in half and place on diagnostic cast
c)Adapt to cast and trim excess more than 2 to
3mm beyond necks of teeth
d)3*3 mm hole is cut through wax over
posterior teeth on both sides of arch and in incisor
area – (Stops of the tray)
www.indiandentalacademy.com
49.
4)Aluminum foil piece is adapted over the wax
and stone cast to provide separation(Prevents
wax from impregnating the surface of tray when
exothermic reaction occurs during setting of
acrylic
5)acrylic resin is mixed, adapted over foil
covered wax,molded
6)Handle is also made and a a wing on either
side to facilitate its removal.
7)Resin is allowed to polymerize,and after it is
hard smoothening and polishing are done
www.indiandentalacademy.com
50. Polysulphide impression
1)Also known as as Mercaptan,Thiokol .
2)The material is packaged into 2 tubes – a
base and an accelerator
3)Base – A liquid polysulphide polymer
mixed with inert fillers
4)Accelerator – Lead dioxide mixed with
small amounts of sulphur and oil,acts as an
oxidation initiator on terminal thiol groups
on the polymer When the two are mixed –
polymer chains are lengthened and cross
linked through oxidized thiol groups
www.indiandentalacademy.com
51.
5)Dimensionally more stable than hydrocolloid .
But contract as curing occurs(Hence have to be
poured within 1 hour
6)Large undercut areas in interproximal region
should be blocked out in the mouth with soft wax
(Or else impression may get locked within mouth
– attempt to force it out- it distorts
7)Hydrophobic- therefore no moisture on the prep
should be there while making the impression
8)Unique quality –it is radiopaque & any
entrapped fragment can be easily seen on a xray
www.indiandentalacademy.com
52.
1)Anesthesia is checked.
2)Custom tray tried,Retraction cord placed
3)On disposable pad squeeze out – 1.5 inches
each of light (Syringe) base and accelerator
4)On second pad – 5 inch strips of regular tray
base and accelerator are placed.
5)Mixing is done ( Tray material mixing is
started 30 seconds before syringe material
mixing)
6)Mixed syringe material is loaded into the
syringe – Using a cone 0r by scraping the back
end across the mixing pad to scoop up the
material
www.indiandentalacademy.com
53.
7)Cord is removed after damping.
8)Syringe material is injected into the
sulcus,around the entire circumference of the
tooth ,until entire tooth is covered
9)Air is directed over the injected material to
spread it evenly.
10)Tray is seated slowly until the stops hold
the tray solidly in one position and held with
light pressure for 8 to 10 mins.
11)After it is set – the impression is removed
as fast and as straight as possible
12)Impression is rinsed,blown dry and soaked
in disinfectant www.indiandentalacademy.com pouring it
solution before
54. Polyvinyl Siloxane
1)Also known as addition silicones
2)Dimensional stability of this group is much
better than that of condensation silicones
3)Usually packaged as two pastes
1)One contains silicone with terminal
silane hydrogen groups and an inert filler
2)The other is made up of a silicone with
terminal vinyl groups,chloroplatinic acid
catalyst and a filler
4)On mixing – addition of silane hydrogen
groups across vinyl double bonds with the
formation of nowww.indiandentalacademy.com
by products
55. 5)Least affected by pouring delays –
accurate even when poured after one week
after removal from the mouth.
6)Earlier formulations released hydrogen –
voids occurred in the setting cast – hence
pouring had to be delayed for 1 day .Now
palladium has been incorporated to counter
the problem (Absorbs hydrogen gas)
7)Hydrophobic material – Surfactants are
incorporated to make it less hydrophobic
and easy to pour
www.indiandentalacademy.com
56.
8)Two pastes can be packaged in separate
tubes(Mixed on a pad) or placed in twin
barelled cartridge(dispenser or gun is used
for mixing)
9)Putty and light body consistencies are
made for his type of silicone also.
10)While mixing putty – gloves should not
be worn as polymerization retardation
results from sulfur derivatives in latex
www.indiandentalacademy.com
57.
1.Paint the custom tray with adhesive at least 15
minutes before the impression is to be made
2)Using a tube dispensed material.
The assistant and operator start mixing at
about same time,until all streaks are eliminated
Then the tray and syringe are loaded
3)Using a cartridge system.
A cartridge of light bodied material is loaded
into one dispenser and cartridge of medium or
heavy bodied material into another
4)DEMO
www.indiandentalacademy.com
58. 5)After mixing the ,cord is removed and
Impression material is injected starting in
one interproximal area
6)Operator applies the light body material with
the syringe and the tray is loaded with
medium/heavy body by the assistant.
7)Then loaded tray is seated firmly in the
mouth and held in place for 7 to 8 minutes
8)Impression is removed as quickly and
straight as possible to avoid distortion.
9)Blown dry and poured with extreme care
www.indiandentalacademy.com
59. Polyether
1)1)It is a copolymer of 1,2 epoxyetane and
tetrahydofuran that is reacted with an
alpha,beta unsaturated acid,to produce
esterification of the terminal hydroxyl
groups
2)double bonds are reacted with ethylene
amine to produce the final
polymer.Aromatic sulfonate produces cross
linking by cationic polymerization.
3)It is packaged in two tubes using a larger
volume of base than accelerator
www.indiandentalacademy.com
60.
4)Highly accurate
5)Improved dimensional stability(Can be
poured even after 1 week)
6)hydrophilic material and hence should not
be stored in moist environment.
7)Stiff material and hence undercuts have to
be blocked out
www.indiandentalacademy.com
61.
1)7.5 inches each of base and accelerator
are dispensed onto a mixing pad.
2)Mixed for 1 minute
3)Syringe and tray are loaded
4)Impression making is carried out similar
to that employed in other types
5)Tray is held in mouth only for 4 mins.
www.indiandentalacademy.com
62. Conventional Silicone Rubber Base
1.Also known as condensation silicones.
2.Base paste
a)Is a liquid silicone polymer with
terminal hydroxy groups mixed with inert
fillers
3.Reactor
a)Is a viscous liquid ,consists of a cross
linking agent ,ethyl silicate,with an organo
tin activator,tin octoate.
www.indiandentalacademy.com
63.
4.Two are mixed –materials are mixed by a
cross reaction between terminal hydroxyl
groups and ethyl orthosilicate
5.Condensation occurs by elimination of
ethyl or methyl alcohol(Evaporation of this
causes shrinkage and hence poor
dimensional instability.-Hence have to be
poured immediately.
www.indiandentalacademy.com
64.
Technique
1)2 inches of base are mixed with two
drops of accelerator to provide the material
used in the syringe.
2)8 inches of base and eight drops of
accelerator are used to for tray filling
material.
3)Other variant employs a putty material
relined with a thin wash
4)Putty has a silica filler content of 75%
(More than double than that in wash).
5)Hence has a very low dimensional change
in the putty impression.
www.indiandentalacademy.com
65.
Preliminary impression is made with a
heavily filled stock tray with putty material.
Preliminary impression serves as a custom
tray for wash impression with less heavily
filled conventional silicone
www.indiandentalacademy.com
66.
Tray preparation (Done before tooth
preparation is begun) and impression making
1)Stock tray is selected
2)Tray adhesive is applied
3)2 scoops putty (Base)+ six drops of
accelerator for each scoop is taken on a pad.
4)Mixed on pad for sometime and then then
transferred to palm on hand and kneaded for
30 seconds,until streak free.
5)Rolled and placed on a stock tray
6)Covered with a polyethylene spacer and
placed in the mouth
www.indiandentalacademy.com
67.
7)Tray is removed from mouth,excess
removed with sharp knife,set aside.
8)After tooth prep,Gingival retraction
procedure is done
9)8 inches of the thin wash silicone base+1
drop of accelerator per inch of base is added
onto mixing pad
10)Mixed for 30 seconds,free of streaks
11)Simultaneous loading is done into the
syringe (operator) and remainder into the
tray(assistant)
www.indiandentalacademy.com
68.
12)Gingival retraction cord is removed after
made damp,and tooth is dried.
13)Syringe material is injected into the
sulcus , and thoroughly around the entire
prepared tooth till it is completely covered
14)Syringe is exchanged for loaded now
15)Tray is seated firmly and held in place for
6 minutes without any pressure
application(Pressure application will
incorporate stresses which will later get
relieved when removed from the mouth
leading to dimensional in accuracy
