Maxillary canine

Maxillary canine The maxillary canine is usually the longest tooth in the mouth. The root is oblong in cross section and usually produces a bulge  called the canine eminence on the anterior surface of the maxilla. The result is that the bone over the labial aspect of he maxillary canine is usually quite thin. In spite of the thin labial bone, this tooth can be difficult to extract simply because of its long

Maxillary incisor teeth

Maxillary incisor teeth The maxillary incisor teeth are extracted with the upper universal forceps (no. 150), although other forceps can be used. The maxillary incisors generally have conic roots, with the lateral ones being slightly longer and more slender. The lateral incisor is more likely also to have a distal curvature on the apical one third of the root, so this must be checked radiographically before t

Maxillary Teeth

Maxillary Teeth In the correct position for extraction of maxillary left or anterior teeth, the left index finger of the surgeon should reflect the lip and cheek tissue; the thumb should rest on the palatal alveolar process (Fig. 7-59). In this way the left hand is able to reflect the soft tissue of the cheek, stabilize the patient’s head, support the alveolar process, and provide tactile information to

SPECIFIC TECHNIQUES FOR REMOVAL OF EACH TOOTH

SPECIFIC TECHNIQUES FOR REMOVAL OF EACH TOOTH This section describes specific techniques for the removal of each tooth in the mouth. In some situations several teeth are grouped together (e.g., the maxillary anterior teeth), because the technique for their removal is essentially the same.

Role of Assistant during Extraction

Role of Assistant during Extraction For a successful outcome in any surgical procedure, it is essential to have a competent assistant. During the extraction the assistant plays a variety of important roles that contribute to making the surgical experience atraumatic, The assistant helps the surgeon visualize and gain access to the operative area by ref!e~ting the soft tissue of unobstructed view of the surgic

Role of Opposite Hand

Role of Opposite Hand When using the forceps and elevators to luxate and remove teeth, it is important that the surgeon’s opposite hand play an active role in the procedure. For the righthanded operator, the left hand has a variety of functions. It is responsible for reflecting the soft tissues of the . cheeks, lips, and tongue to provide adequate visualization of the area of surgery. It helps to protec

PROCEDURE FOR CLOSED EXTRACTION

PROCEDURE FOR CLOSED EXTRACTION An erupted root can be extracted using one of two major techniques: (1) closed Or (2) open. The closed technique is also known as the simple.. or forceps technique. The open technique is also known as the surgical, or flap technique. This section discusses the closed or forceps extraction technique the open technique is discussed in Chapter 8. The closed technique is the most f

PRINCIPLES OF FORCEPS USE

PRINCIPLES OF FORCEPS USE The primary instrument used to remove a tooth from the alveolar process is the extraction forceps. Although elevators may help in the luxation of a tooth, the instrument that does most of the work is the forceps. The goal of forceps use is twofold: (1)  Expansion of the bony socket by use of the wedge-shaped beaks of the forceps and the movements of. the tooth itself with the forcep

Mechanical Principles Involved In Tooth Extraction

Mechanical Principles Involved In Tooth Extraction. he removal of teeth from the alveolar process employs the use 01 the following mechanical principles and simple machines the lever, wedge, and wheel and axle. Elevators are used primarily as levers. A lever is a mechanism for transmitting a modest force-with the mechanical advantages of a long lever arm and a short efector arm into a small movement against gr

CHAIR POSITION FOR FORCEPS EXTRACTION

CHAIR POSITION FOR FORCEPS EXTRACTION The positions of the patient, chair, and operator are critical for successful completion of the extraction. The best position is one that is comfortable for both the patient and surgeon and allows the surgeon to have maximal control of the force that is being delivered to the patient’s tooth through the forceps. The correct position allows the surgeon to keep the ar
