To luxate and remove teeth which cannot be engaged by the beaks of the forceps | ELEVATORS |
To remove roots fracture or carious teeth | ELEVATORS |
To loosen the tooth prior to the application of forceps | ELEVATORS |
to split the tooth which have had grooves cut in them | ELEVATORS |
PROCEDURE OF CLOSED EXTRACTION | Loosening of soft tissue attachment from the cervical portion of the tooth, Luxation of the tooth with a dental elevator, Adaptation of the forceps to the tooth, Luxation of the tooth with the forceps, Removal of the tooth from the socket. |
PROCEDURE OF CLOSED EXTRACTION:allows the surgeon to ensure that profound anesthesia has been achieved. | Loosening of soft tissue attachment from the cervical portion of the tooth. |
PROCEDURE OF CLOSED EXTRACTION:to allow the elevator and tooth extraction forceps to be positioned more apically, without interference from or impingement on the soft tissue of the gingiva. | Loosening of soft tissue attachment from the cervical portion of the tooth. |
TRUE OR FALSE: The adjacent gingival papilla of the tooth should also be reflected to avoid damage by the insertion of the straight elevator. | TRUE |
PROCEDURE OF CLOSED EXTRACTION:to create movement to facilitate movement of the tooth | Luxation of the tooth with a dental elevator. |
PROCEDURE OF CLOSED EXTRACTION:Expansion and dilation of the alveolar bone and tearing of the periodontal ligament | Luxation of the tooth with a dental elevator. |
TRUE OR FALSE: The straight elevator is inserted parallel to the tooth into the interdental space | FALSE |
PROCEDURE OF CLOSED EXTRACTION:The forceps are then seated onto the tooth so that the tips of the forceps beaks grasp the root underneath the loosened soft tissue | Adaptation of the forceps to the tooth. |
TRUE OR FALSE: the buccal beak is usually seated first and then the lingual beak | FALSE |
TRUE OR FALSE: Use slow, steady force to displace the tooth buccally rather than a series of rapid, small movements that do little to expand bone. | TRUE |
TRUE OR FALSE: The major portion of the force is directed toward the thickest and therefore weakest bone | FALSE |
PROCEDURE OF CLOSED EXTRACTION: what force is used to remove tooth from socket | tractional |
TRUE OR FALSE: Tractional forces should be maximized, because this is the last motion that is used once the alveolar process is sufficiently expanded and the periodontal ligament is completely severed. | FALSE |
ROLE OF OPPOSITE HAND:The left hand is responsible for _____ the soft tissues of the cheeks, lips, and tongue to provide adequate_____ of the area of surgery. | reflecting; visualization |
ROLE OF OPPOSITE HAND:The left hand helps to protect other teeth from the ____ should it release suddenly from the tooth socket | forceps |
ROLE OF OPPOSITE HAND:The left hand helps to stabilize the patient's ___during the extraction process | head |
TRUE OR FALSE: In some situations, greater amounts of force are required to expand heavy alveolar bone; therefore the patient's head requires active assistance to be held steady. | TRUE |
TRUE OR FALSE: The dominant hand plays an important role in supporting and stabilizing the jaw when mandibular teeth are being extracted. | FALSE |
ROLE OF OPPOSITE HAND:The opposite hand is often necessary to apply considerable pressure to expand heavy mandibular bone, and such forces can cause discomfort and even injury to the ___ unless a steady hand counteracts them. | TMJ |
"ROLE OF OPPOSITE HAND:A bite block placed on the _____side is also used to help support the jaw in this situation." | contralateral |
TRUE OR FALSE: the opposite hand supports the alveolar process and provides tactile information to the operator concerning the expansion of the alveolar process during the luxation period. | TRUE |
ROLES OF FINGERGUARD:before | retract |
ROLES OF FINGERGUARD:during | guard; tactile information of bone expansion |
ROLES OF FINGERGUARD:after | compression; para pag magheal hindi magkaroon ng undercut |
EXTRACTION OF A MAXILLARY ANTERIOR TOOTH (CENTRAL INCISOR). | initial labial (L) pressure o (i); the tooth is brought back to its original position, with direction of motion continuing to the palatal (P) side (ii); the final extraction movement is curved, with the concave part facing upwards (iii) |
EXTRACTION OF MAXILLARY LEFT TOOTH (FIRST PREMOLAR | Extraction movements: a buccal (B), b palatal (P), c final extraction movement |
Extraction of anterior mandibular tooth (central incisor). | Extraction movements: a buccal (B), b lingual (L), and c final extraction movement, which is curved, with the concave part of the arch facing downwards (that is, the opposite direction compared to the extraction of maxillary teeth) |
EXTRACTION OF A MANDIBULAR LEFT POSTERIOR TOOTH (FIRST MOLAR). | Extraction movements: a buccal, b lingual, c final extraction movement, always towards the buccal side, outwards and downwards |
extraction of deciduous molar with forceps: forceps are positions _______ on the crown not the _____ of the tooth | mesially or distally; center |
RULES (closed technique):Beaks of the forceps should be seated as far ____as possible without compression of the soft tissue | apically |
RULES (closed technique):Beak should be _____that the MD diameter of the tooth, so that there is maximal adaptation | narrower |
RULES (closed technique):Placement of the beaks of the forceps should be as _____as possible to the long axis of the tooth | parallel |
TRUE OR FALSE: RULES (closed technique):The application of excessive force should be encouraged | FALSE |
REASONS OF ROOT FRACTURE/BREAKAGE | 1. Improper application of beaks of forceps
2. Wrong type of forceps has been used
3. Presence of extensive caries
4. Brittleness due to age or non-vitality of the pulp of tooth
5. There is peculiar root formation
6. Due to excessive density of the surrounding bone
7. Improper application of force |
TRUE OR FALSE: Do not refer extraction as a simple procedure | TRUE |
TRUE OR FALSE: sometimes you cannot anticipate breakage | FALSE |
TRUE OR FALSE: You don’t need to inform the patient of the possibility of fracture if you are sure that the extraction is simple because you might scare the patient | FALSE |
TRUE OR FALSE: Never try to cover-up the breakage of a tooth | TRUE |
RULES IN THE USE OF ELEVATORS:Never use adjacent tooth as a fulcrum unless that particular tooth is ______ | subsequently extracted |
if walang radiolucency, do you still need to curette? | yes but more gentle |
cold compress: how long and what is the interval | 15 - 30 minutes on tanggal for 30 minutes; at least 24 hours for prevention |
do you still recall if resorbable yung suture? | yes to check healing |
