Maxillary Fourth Premolar Extraction in the Dog | VETgirl Veterinary Continuing Education Videos
In this VETgirl veterinary continuing education video, Dr. Brett Beckman, DVM, FAVD, DAVDC, DAAPM will review the sequence of extraction of the maxillary fourth premolar tooth in the dog. Principles of extraction technique are described and demonstrated in detail. The periosteal elevator provides the means to elevate the periosteum and the attached and unattached gingiva from the bone allowing access for bone removal to facilitate extraction. Proper angulation, pressure and movement are keys to successful, atraumatic flap mobilization. A 701 L crosscut tapered fissure bur is used to remove vestibular bone starting coronally and moving apically. Once the vestibular bone is removed this bur creates a groove mesial and distal to further facilitate ease of extraction and creating a place for the locating/elevator. Partial apical resorption of the mesial roots are present, resulting in a root tip fracture. We take advantage of the fracture by demonstrating a simple technique to safely remove the root tip. A diamond football bur aids in smoothing the bone prior to closure. Closure is accomplished with a simple interrupted pattern with 4-0 monocryl in the attached gingiva of the vestibular and palatal mucosa and finished with a cruciate pattern in the unattached gingiva.
