Extraction of fractured teeth and roots

Question 1

Extraction technique using root tip forceps

Answer 1

• Same as tooth forceps -Tooth must protrude out of gingiva to grasp→ Gingiva reflected
• Same movements and position as teeth extraction

Question 2

Elevator used for root tips

Answer 2

Straight elevator

Question 3

Extraction of single rooted teeth with destroyed crown

Answer 3

• Straight elevator
• Concave surface of elevator between root and alveolar bone at mesial or distal surface
• Alveolar bone used as fulcrum
• Rotational forces applied to displace root

Question 4

Extraction of multirooted teeth with destroyed crown

Answer 4

If roots above alveolar bone→ Sectioned and separated

→After buccal/lingual groove formed with fissure bur to interradicular bone

-Roots removed one at a time→ Root tip forceps or elevator

Question 5

Sectioning of multirooted teeth with elevator

Answer 5

• Straight elevator→ placed in bi-furcation w/ concave surface on distal root
• Fingers support alveolar process
• Roots separated using rotational movements→ Elevates distal root
• Mesial root removed with T-bar handle or seldin elevator→ Removes interradicular bone and the root with rotational pressure upwards

Question 6

Extraction of root tips in single rooted teeth

Answer 6

• Double angled elevators used→ sharp tip
• Small root tip→ Narrow angled elevator between bone and tip w/ apical pressure to luxate→ mesial and distal pressure to immobilise and remove

Question 7

Extraction of root tips in multi- rooted teeth

Answer 7

• Removal of interradicular bone w/ round bur
• Elevator between bone and tooth→ Apical pressure to remove
• Root tip can also be removed with endo file
