The origins of surgery can be traced back many centuries, with practitioners using various materials and techniques for closing wounds. Ancient methods included using ants or thorns to close wounds. In more modern times, catgut made from sheep intestine was used. Post-World War II, sutures were developed with needles attached to reduce tissue trauma. Sutures are classified based on material and absorbability, and appropriate suture selection depends on factors like the tissue and wound characteristics.
Collagen sutures are made from bovine or equine collagen. They are absorbable and elicit a mild foreign body reaction. Collagen sutures are absorbed slowly by the body over 60-90 days as the collagen is broken down. They have good handling properties and knot security. Common uses include skin closure and plastic surgery procedures.
Principles and Philosophy of CPD DesignAamir Godil
The document discusses the principles and philosophies of cast partial denture design, including stress equalization, physiologic basing, and broad stress distribution. Stress equalization aims to balance stresses on abutment teeth and residual ridges through the use of stress breakers like hinges or flexible connectors. Physiologic basing involves compressing tissues during the impression to position prosthetic teeth above the occlusal plane at rest. Broad stress distribution advocates distributing forces over many teeth and soft tissues through additional clasps and broad denture bases. The philosophies aim to prevent trauma to remaining structures by managing stresses.
The document discusses principles of wound closure through suturing. It describes various suturing instruments including needles, needle holders, forceps and scissors. It explains the principles of proper suturing technique such as bite size, tension, and knot tying distance from the wound. Different suture materials are also outlined, categorizing them based on absorbability, source, gauge and filament type. Common absorbable and non-absorbable suture materials are named and their properties and uses discussed.
Trituration is the process of mixing amalgam alloy powder with mercury to create an amalgam. There are two methods: hand trituration using a mortar and pestle, or mechanical trituration using a vibrating machine. The objectives are to remove oxide layers, reduce particle size, and create an evenly mixed amalgam. Both methods involve mixing the alloy and mercury until a workable consistency is reached, then removing excess mercury. Mechanical trituration has advantages like shorter mixing times and standardization but disposable capsules are more expensive. The effects of trituration time on properties like strength and creep depend on factors like alloy type.

The document discusses the philosophy of designing removable partial dentures (RPDs). There are several key principles that must be considered in RPD design:
1. Stress distribution - Forces acting on RPDs should be distributed broadly across remaining teeth and soft tissues to minimize damage.
2. Physiologic basing - Recording the soft tissue ridge under functional pressure better supports the denture base and stimulates tissue health.
3. Broad coverage - Using multiple clasps and ensuring broad denture base coverage distributes forces over more surfaces.
Proper consideration of stress distribution, tissue support, and force dispersion are fundamental to preserving remaining oral structures with an RPD.

Suturing is the process of closing wounds using needles and thread. There are a variety of suture materials that can be used, and the doctor will choose one appropriate for the wound. Sutures can be absorbable, meaning they dissolve on their own in the body, or non-absorbable, requiring later removal. Common suture techniques include continuous sutures using a single strand, interrupted sutures using multiple cut strands, and deep sutures placed under tissue layers. Suture removal times vary depending on the body location but generally occur within 7-14 days.

3. What is a Suture ??
Suturing is the act of bringing tissues
together and holding them in apposition
until healing takes place.
4. What is the Purpose or Goal of
Suturing ??
Provide adequate tension of wound closure
without dead space…but loose enough to obliviate
tissue ischaemia & necrosis.
Maintain Haemostasis.
Healing by primary intension.
5. Provide support for healing until it is no longer
needed.
Post operative pain control.
Prevention of bone exposure.
Proper flap positioning.
7. A needle holder has a locking handle and a short, stout beak
Needle Holder:
8. The faces of the beaks of the needle holder are cross-hatched to ensure a
positive grip on the needle
9. To control the locking handles the surgeon must hold the
instrument properly.
The thumb and ring finger are inserted through the rings.
The index finger is held along the length of the needle holder
to steady and direct it.
The second finger aids in controlling the locking mechanism.
10. The index finger should not be put through the finger ring,
because this will result in a dramatic decrease in control.
The first and second fingers help direct the instrument.
11. Tissue Forceps
commonly used for this purpose for dentoalveolar suturing
are the Adson forceps.
Adson forceps with teeth.
12. Scissors
The final instruments necessary for placing sutures are
suture scissors.
13. SUTURE MATERIALS
Ideal properties of Sutures :

19. Absorbable Sutures
Plain Gut
Derived from submucosa of
sheep intestines
Not a true monofilament
Less than 10 day life span in
tissue
100 times the bacterial
adhesion than that of Nylon or
Polypropylene
20. Absorbable Sutures
• Chromic Gut
Plain gut tanned with chromium
salts
Improved strength and duration
Duration is 2-3 weeks
Knot security greater than plain
gut
Absorption by proteolytic
enzymes
21. Absorbable Sutures
• Dexon (polyglycolic or PGA)
Monofilament which is braided
Un-coated Dexon S and coated
Dexon Plus
More durable than gut sutures
Absorbed by hydrolysis of ester bond
Sutures lost orally is 16-20 days
22. Absorbable Sutures
• Vicryl
Copolymer of glycolic and lactic
acid in a 9:1 ratio; Polyglactin 910
Nearly identical properties as
Dexon
Strength loss after 16-20 days
Absorbed by hydrolysis of ester
bond
Braided suture like Dexon
23. Non-absorbable Sutures
Silk
70% natural silk, silk worm larvae
Main advantage is favorable
handling
Knot security is good
Tissue response to silk is severe
Braided material, potential for
infection is great
24. most commonly used sutures for the oral cavity
is 3-0 black silk.
The size 3-0 has the appropriate amount of
strength; the polyfilament (braided) nature of the
silk makes it easy to tie and is well tolerated by the
patient’s tongue.
The color makes the suture easy to see when the
patient returns for suture removal.
25. Non-absorbable Sutures
Nylon
Synthetic polyamide polymer
Available in monofilament or
multifilament
Poor knot security
Among the best for minimizing
infection
Face: 5-0 or 6-0 Nylon
Scalp: 3-0 Nylon
26. Non-absorbable Sutures
Polypropylene (Prolene)
Similar to Nylon, synthetic
monofilament polymers
Breaking strength less than Nylon
Knot security and ease of tying
greater than Nylon
Absorption is non-existent, good
for contaminated wounds
27. Suture Needle
Anatomy of the needle :
Point -This portion of the needle extends from the tip to the
maximum cross-section of the body.
Body -This part of the needle incorporates the majority of the
needle length.
Swage -The suture attachment end creates a single, continuous
unit of suture and needle.
29. Taper-Point •Suited to soft tissue
•Dilates rather than cuts
Reverse
cutting
•Very sharp
•Ideal for skin
•Cuts rather than dilates
Conventional
Cutting
•Very sharp
•Cuts rather than dilates
•Creates weakness allowing suture
tear out
Taper-cutting
•Ideal in tough or calcified tissues
•Mainly used in Cardiac &
Vascular procedures.
NEEDLE POINT GEOMETRY
31. The cutting portion of the needle extends about one third
the length of the needle, and the remaining portion of the
needle is rounded.
Tapered needles are used for more delicate tissues, such
as in ocular or vascular surgery.
Care must be taken with cutting needles, because they
can cut through tissue lateral to the track of the needle if
not used carefully or correctly.
Suture Needle
32. Available Suture Sizes
Size: Refers to the diameter of the suture
The more “0’s” in the number, the smaller the suture
Microsurgery/repair: 9-0 or 10-0 suture
Facial skin closure: 5-0 or 6-0 suture
Trunk or extremities: 4-0 or 5-0 suture
Scalp: 3-0 suture
Muscle, deep skin, intraoral mucosa: 3-0 or 4-0 suture
33.
34. principles for placing the needle in tissue:
1. Force should always be applied in the direction that follows the
curvature of the needle.
2. Suturing should always be from a movable to a non movable
tissue.
3. Excessive tissue bites with small needles should be avoided, as it
will be difficult to retrieve them.
4. Only sharp needles with minimal force should be used.
Ethicon (1985)
PLACEMENT OF NEEDLE IN TISSUE
35. 5. The needle should be grasped in the body one-quarter to
one-half of the length from the swaged area.
6. The swaged area should not be held; this may bend or
break the needle.
7. The needle should never be forced through the tissue.
8. Retrieving the needle from the tissue by the tip should
be avoided. This will damage or dull the needle.
36. 9.The body should be grasped as far back as possible.
10. Sutures should be placed in keratinized tissue
whenever possible.
11. An adequate tissue bite is required to prevent the flap
from tearing.
37. KNOTS AND KNOT TYING
“Suture security is the ability of the knot and
material to maintain tissue approximation during the
healing process” (Thacker and colleagues, 1975).
Failure is generally the result of untying owing to
knot slippage or breakage.
38. 1. The loop created by the knot.
2. The knot itself, which is composed of a number of tight “throws”;
each throw represents a weave of the two strands.
3. The ears, which are the cut ends of the suture.
A sutured knot has three components
Thacker and colleagues, 1975
39. There are basically three types of knot used for
securing suture;
1. Square knot
2. Surgeons not
3. Granny knot
40. Square knot
Square knot is formed by wrapping suture around needle holder
once in opposite directions between ties.
41. Surgeon’s knot
Surgeon’s knot is formed by two throws of suture around
needle holder on first tie and then one throw in opposite
direction on second tie.
44. Knot tying
1. Knot must be firm ….no slippage.
2. Knot should not be placed on the incision lines to
avoid wicking.
3. Avoid excessive tension…..crimping of suture.
4. Maintain adequate tension …….avoid
excess……..necrosis.
45. Knot tying
5. Knot ends must be 2-3mm.
6. An added throw does not increase the strength of the
knot.
7. After the first loop is tied it is necessary to maintain
traction at one end of the strand to avoid loosening of
the throw.
8. Final tension or final throw should be as nearly
horizontal as possible.

48. Interrupted Sutures
Most commonly used in the oral cavity.
This suture goes through one side of the wound, comes up through
the other side of the wound, and is tied in a knot.
When placing multiple adjacent interrupted sutures, they can usually
be spaced about 1 to 1.5 cm apart.
49. indications
where maximum interproximal coverage is required.
Edentulous areas- tuberosity & molar areas.
Partial thickness flaps.
Incase of vertical incisions.
Bone regeneration procedures.
Osseo integrated implants.

holder
52.
53.
54. Advantages :
1. They are stronger & loosening of any one suture will not
cause the others to loosen.
2. In areas of tension when strong closure is required interrupted
sutures are preferred.
3. Incase of infection….removal of infected sutures is sufficient.
55. Figure of 8 Suture
Indications:
When flaps are not in close apposition because of
apical flap displacement.
The major disadvantage being presence of suture
between the 2 flaps.
57. Horizontal Mattress Suture
1. Used in areas of diastema or wide interdental spaces
to properly adapt the inter-proximal papilla.
2. This technique is also useful when the edges of the papilla
are very fragile, because the suture can enter the tissue
further away from the wound edges.
3. Helps in tissue eversion.
58. The use of this suture decreases the number of individual sutures
that must be placed.
59. Vertical Mattress Suture
1. Recommended for bone regeneration procedures.
2. provides maximum tissue closure.
3. avoids suture contact with implanted material by
avoiding wicking.
4. Particularly suited for papillary management.
61. Continuous Sutures
Advantages:
1. One can include as many teeth as required.
2. Minimizes need for multiple knots.
3. Allows independent placement & tension
of buccal & lingual/ palatal flaps
4. Simple
62. Continuous Locking Suture
Usually used in long edentulous areas.
Technique :
1. Initially a single interrupted suture is given.
2. Needle is inserted from outer surface of buccal flap & inner
aspect of the lingual flap.
3. Needle then passed through the remaining loop of the suture
& pulled tight.
4. Procedure continued & final suture tied at the terminal end.
