Perfectly

Ringed instrument with beak w/ Crisscross serrations/surface

Needle Holder

Bone file Used in pull motion

Bone file with straight/horizontal serration

Bone file Used in push and pull motion

Bone file with criss-cross serration

Used to scoop out granulation tissue or necrotic tissue

Surgical or Bone Curette

Used to spread out and debride surgical site of debris

Surgical or Bone Curette

Used in post-extraction debridement in removing any kinds of tissue or debris seen in the site after extraction

Surgical or Bone Curette

Also used in removal of cystic lesion or cystic tissue inside the socket or alveolar bone

Surgical or Bone Curette

Sucks out fluid faster than saliva ejector

HIGH VOLUME EVACUATOR

Instruments used for extraction of teeth with the purpose of luxating/loosening the tooth from the alveolar process

ELEVATORS

If you use it for prying out the tooth, it is like a _____ lever

First-class

If you use it straight into the PDL space, it works more like a ______

Wedge

Crossbar is a _________ type of elevator

Wheel and axle

Active component of elevators

Blade

A fine-graded instrument inserted into the PDL space before they tear up the PDL fibers

Luxator

Flat instruments used to insert in the pdl space to sever periodontal ligaments.

Periotome

● The blade is roughly 90 degrees on the shank ● Also works as a wheel and axle ● Used when the object is hard ● A.K.A. pennant elevator ● Has a straight handle

Cryer Elevators

● Blade is the same as the Cryer, roughly 90 degrees on the shank ○ The difference is that it has a crossbar angle, it is perpendicular to the shank ● It needs more force compared to the cryer ● If you don’t use it directly you might fracture the mandible

Crossbar Elevators

Elevator used for removing root fragments

Crane Elevators

● For gross bone removal ● Like a nail clipper For: Bone removal during extraction in the absence of burs to expose embedded tooth Removal of overlying bone for the exposure of cystic lesion for enucleation

RONGEUR FORCEPS

Removal of fractured off apical third or root tips (Last 2-3mm of the tooth)

ROOT TIPS PICK

For cutting sutures and tissues/mucosa (universal use)

IRIS SCISSORS

Solely for cutting sutures

SUTURE SCISSORS

Expensive scissors For cutting excess tissue

GOLDMANN-FOX

Used for cutting small tissue or mucosa at the posterior area Much like the Iris scissors but have longer shank

DEAN’S SCISSORS #9

Used to hold onto the tooth and expand the alveolar bone to facilitate extraction

Forceps

For extracting maxillary centrals, laterals, cuspids, and premolars, and any root fragment

150 Forceps

Specific for Mx root fragments, but smaller

69 Forceps

Forceps with Same function as 69 ○ maxilla ○ small root fragments

65 Forceps

specific for upper third molars

240 Forceps

for maxillary first or second molars (scallops)

18 Forceps

for maxillary first or second molars (Prongs)

88 Forceps

for anteriors, premolars, and root fragments of mandibular teeth

151 Forceps

Extracts Md. molars with definite furcations

16 Forceps (Cow Horn)

Nicknamed as double wedge forceps

16 Forceps (Cow Horn)

Double scalloped beak, slightly bent handle, Md. forceps

215 Forceps

Double scalloped beak, Straight handle, Md. forceps

17 Forceps

Beak is 90o from the handle (forceps)

English Type Forceps

Forceps w/ beak and bumper

Physics forceps

Forceps are held with your palm ____, palm ____ Beak is pointing _____ from palm

palm open and palm up Beak pointed away from palm

○ Has 2 edges ○ Used to section teeth ○ Insert in the furcation area, using a mallet split it into mesial and distal half

bibevel chisel

○ Only one edge ○ Used for expanding or removing bone ○ Like the one used by wood carvers ○ Using to remove mandibular tori. Better if the bevel is new

mono-bevel chisel

Two uses of cautery

○ Cutting - removing tissue, making an incision and opening a flap ○ Coagulation - if there is a bleeding point, use to control the bleeding

Electro cautery tip used for coagulation

Ball

Electro cautery tip used for For excision or removing tissue

loop

Electro cautery tip used for cutting

Straight end

It forces the mouth to open when you close the ratchet, used in pediatric patients

Mouth gag

Syringe used for irrigating, Brand name called asepto syringe

Bulb syringe

Looks like a normal syringe but it has a spring to aspirate Used for irrigation

Irrigating syringe

Drain to evacuate abscess

Penrose drain

Most commonly used suture

3-0 or 000 suture for OS (silk)

Largest suture size:

Smallest suture size:

6-0

Absorbable sutures: (4)

Naturally occurring, made of intestinal lining of sheep or calf ○ Chromic gut ○ Plain gut Synthetic, made of polymer ○ Polyglycolic ○ Polyglactin ○ Poliglecaprone

Most commonly used non absorbable sutures (3)

Silk Nylon Polypropylene

Most commonly used suture material w/ good tying properties

Silk

Amount of time needed for gut sutures to be absorbed

1. PLAIN GUT - Enzymatically dissolves in about 7 days 2. CHROMIC GUT - Chromic salts added to slow down absorption rate of suture material (about 3 months)

The apex forms a cutting surface which facilitates penetration of tough tissues such as mucosa Triangular in shape

Conventional Cutting needle

Needle type For use in tissues that are not keratinized

Taper needle

Similar to a cutting needle except that the cutting edge faces down instead of up

Reverse Cutting needle

most common & ideal needle size in OS

½ circle

also called atraumatic sutures or needles

Swaged needle
