the shaping of the peripheries of a dressing by manual manipulation of the tissue adjacent to the borders to duplicate the contour and size of the vestibule

border mold

mode of self-cure or setting of a dressing in which the ingredients unite in a chemical process that starts as son as the blending is complete; the setting time is influenced by warm temperature and the addition of an accelerator

chemical cure

to approximate, as the edges of a wound; bring edge to edge with no overlap


constituent of clove oil; used in early periodontal dressings with zinc oxide for its alleged antiseptic and anodyne properties; more recently found to be toxic, to elicit allergic reactions, and to hinder, more than promote, healing


the termination of bleeding by mechanical or chemical means or by the complex coagulation process of the body that consists of vasoconstriction, platelet aggregation, and thrombin and fibrin synthesis


a process by which water slowly penetrates the suture filaments, causing breakdown of the suture's polymer chain; yields a lesser degree of tissue reaction


application of a wire or thread (suture) to hold or constrict tissue


presence of potentially pathogenic microorganisms; opposite of asepisis: the absence of infectious material


a stitch or series of stitches made to secure apposition of the edges of a surgical or traumatic wound


a suture that holds the margins of an incision close together

suture apposition

the fusion of a suture material to the needle, which allows for a smooth eyeless attachment; the suture will then pass through the tissue as smoothly as possible



amount of strength the suture material will retain throughout the healing period; as the would gains strength, the suture loses strength

tensile strength

light activation using a photocure system; shorter curing time than self-cure; does not start setting until the light is activated, thereby allowing longer working time for adapting the dressing material

visible light-cure

A ______ is a strand of material used to ligate blood vessels and approximate tissue.


Functions of Sutures

  • Close Periodontal Wounds and Secure Grafts
  • Assist in Maintaining Hemostasis
  • Reduce Posttreatment Discomfort
  • Promote Primary Intention Healing
  • Prevent Uderlying Bone Exposure
  • Protect Healing Surgical Wound from Foreign Debris and Trauma

Characteristics of Suture Materials


Handle Comfortably and Easily

Pass through Tissue with Minimal Trauma

Cause Little or No Tissue Reaction

Possess a High Tensile Strength

single strand of material


several strands twisted or braided together


capable of causing adverse tissue reaction


developed to reduce tissue reactions and unpredictable rates of absorption commonly found in natural sutures


approximate tissue until wound heals sufficiently to endure normal sress

absorbable sutures

*implant flap closure*

digested by body enzymes

*surgical gut & chromic gut*

natural absorbable sutures

*used for extraction socket & bone grafting*

broken down by hydrolysis

synthetic absorbable sutures

not digested by body enzymes or hydrolyzation; must be removed within specific time period

nonabsorbable sutures


natural nonabsorbable

nylon, polyester, polypropylen

synthetic nonabsorbable

The diameter of sutures ranges from ____ to _______.

1-0 to 11-0

More zeros the ____ the diameter and fewer zeros equals ______ diameter.



What shape can a needle be?





Most needles are _______ _______ formulated and sterilized for surgical use.

stainless steel

it has two opposing cutting edges, with a third located on outer convex curve of needle

reverse cut (B)

reverse cut (B)

it consists of two opposing cutting edges and a third within the concave curvature of the needle

conventional cut (A)

conventional cut (A)

______ and ______ knots are the most frequently used in dentistry.



A knot should be tied as ______ as possible.


Knots should be tied on the _____ aspect for easier access for removal and ___ to ____ mm of a tail should be left to assist in locating at the time of removal.


2 to 3

stitch is brought over a loop of the preceding one, thus forming a series of loops on one side of the incision and a series of stitches over the incision

blanket stitch (A)

blanket stitch (A)

What stitch is shown in B?

What stitch is shown in B?


a series of stitches tied at one or both ends

continuous uninterrupted

a term applied to a suture that encircles a tooth for suspension and retention of a flap


where the flaps are on both the lingual and facial sides, interdental ligation joins the two by passing the suture through each interdental area

interdental (C)

interdental (C)

when a flap is only on one side, facial or lingual, the sutures are passed through the interdental papilla, around the tooth, and into the adjacent papilla

sling or suspension (D)

sling or suspension (D)

Sutures are schedules for removal ___ days after the surgery or no longer than ____ days to prevent tissue infection and promote healing.



Suture removal can cause ____; high-risk patients may need antibiotic premedication for suture removal.


Steps for Suture Removal

Steps for Suture Removal

A: Suture grasped by pliers near the entrance into tissue.

B: Suture pulled gently up while scissor is inserted close to the tissue. Suture is cut in the part previously buried in the tissue

C: Suture is held up for vertical removal.

D: Suture is pulled gently to bring it out on the side opposite from where it was cut.

Dressings may be placed over the surgical wound following surgery. Dressings are not used to _____ the wound but to ______ the tissue.



What are the four types of dressings used?

Zinc Oxide with Eugenol Dressing (Bad Taste/Allergic Reactions)

Chemical-Cured Dressing (Easy to work with)

Visible Light-Cured Dressing (Looks like Gingiva)

Collagen Dressing (Wound Healing)
