Q

Patient position for extraction of Maxillary teeth

A

-Patient mouth at same height as dentist shoulder
-120 ° angle between dental chair and floor
-Occlusal surface of maxillary teeth at 40 ° when open compared to horizontal

60
Q

Patient Chair position for extraction of mandibular teeth

A

-110 ° angle between chair and floor
-Occlusal surface of mandibular teeth parallel to floor when mouth open
-Patient mouth at level of dentist elbow

61
Q

Surgeon position for extraction with forceps for maxillary teeth

A

-Infront or to the side of the patient

62
Q

Surgeon position for extraction with forceps for mandibular teeth

A

-Right posterior and anterior teeth→ behind patient
-Left mandibular teeth→ in front of patient

63
Q

<p>Desmotome use</p>

A

<p>-Pen grip with dominant hand</p>

<p>-Positioned at bottom of gingival sulcus to sever PDL</p>

<p>-Continuous motion from mesial to distal→ buccally then lingually/palatal</p>

<p>-Non dominant hand→ index finger and thumb positioned on buccal and palatal</p>

64
Q

<p>Elevator use</p>

A

<p>Push or reflect gingiva→ allows extraction forceps to grasp tooth beneath cervical line</p>

65
Q

Extraction technique with forceps

A

-Beaks of forceps at cervical line of tooth→ parallel to long axis of tooth
-Gentle initial buccal then lingual/ palatal movements
-Gradual increase in pressure first at buccal(bone thinner and more elastic)
-Rotational force if roots single and conical
-Slight traction to facilitate extraction but not used at final stage
-Final movement → Maxilla=buccal and curved outwards and upwards
→ Mandible=Buccal direction and curved outwards and downwards

66
Q

Extraction technique of elevator

A

-Held in dominant hand w/ index finger along blade
-Used buccally(not lingual/palatal)
-Concave surface contacts mesial or distal
-Alveolar bone used as fulcrum
-In maxillary posterior teeth- perpendicular to long axis and in rest→ perpendicular, parallel or at angle

67
Q

Protective measure during elevator use

A

Cotton wool or gauze between finger and palatal to avoid injury is elevator slips

68
Q

Post extraction care of socket

A

-Periapical curette used at bottom of socket(removes granulation tissue preventing cyst)
-If sharp and bony edges-ronguers forceps or bone file to smooth alveolar margin
-Haemostasis aided by pressure on socket w/ gauze for 30-45 min

69
Q

<p>Post operative instructions</p>

A

<p>-Rest</p>

<p>-Analgesia</p>

<p>-Edema</p>

<p>-Bleeding</p>

<p>-Antibiotics</p>

<p>-Diet</p>

<p>-Oral hygiene</p>
