Tooth Extraction Fundamentals and Protocol

Vocabulary flashcards covering preparatory steps, forceps movements, tooth-specific extraction techniques, and post-extraction procedures based on the oral surgery lecture.

Throat Screen

A 4x4 piece of sterile gauze placed in the patient's mouth during extraction to block objects, such as an extracted tooth, from falling into the throat.

Simple Extraction

An extraction procedure where no incisions or sutures are typically needed, and a surgical handpiece is not used for bone removal or tooth sectioning.

Surgical Extraction

An extraction procedure involving surgical access via elevating a mucoperiosteal flap, bone removal or tooth sectioning using a surgical handpiece, and typically requiring sutures.

Center of Resistance

The point located at the center of the embedded root that forceps attempt to reach as closely as possible by seating apically.

Purchase Point

A location between the tooth and alveolar bone where an elevator blade engages to feel resistance while luxating the tooth.

Outward Motion

A forceps movement toward the buccal or labial direction, serving as the initial movement for most permanent teeth.

Inward Motion

A forceps movement toward the lingual direction, serving as the initial movement for most primary teeth due to root orientation.

Rotary Motion

A rotational forceps movement used as the initial motion for teeth with single conical roots, such as upper central incisors and lower premolars.

Upper First Premolar Extraction Rule

Rotational force must be avoided because upper first premolars often have two roots splitting in the apical third that can easily fracture.

Upper Molar Extraction Motion

Forceps movement that favors buccal pressure over palatal pressure to avoid pushing the long, bulky palatal root into the maxillary sinus.

Lower Premolars

Teeth considered among the easiest to extract due to their straight, single conical roots, with rotational motion being the primary movement.

Lower Molars

Teeth considered among the hardest to extract due to divergent roots and dense posterior mandibular bone, requiring slow buccal and lingual pressure without rotation.

Squeezing Cortical Plates

A post-extraction step where buccal and lingual cortical plates are compressed with fingers to reduce socket size, which is avoided if future orthodontics or dental implants are planned.

CSI Acronym

A post-extraction socket cleanup protocol standing for Curettage, Smooth bone, and Irrigate.

Curettage

The process of using a curette in the extracted tooth socket to remove residual cysts, radicular cysts, granulation tissue, and root or bone debris.

Irrigation

The post-extraction process of flushing out the tooth socket with sterile saline, typically using a Monoject syringe, to remove remaining bone or root debris.
