These are your sharpest teeth and are used for ripping and tearing food apart. Although the therapeutic occlusal form may incorporate canine guidance for convenience and to facilitate physiological adaptation, a “slow” development to group function following these changes need not be modified and indeed may be desirable if it involves a wider distribution of forces. Once erupted and grown to their maximum length, upper canines in baboons are continuously worn against the lower canines and the first premolar (P3) teeth. This fact can be used in restorative procedures. In other animals the canine is most laterally loaded during tearing of food. Repeated stress may lead to strain involving stretching or tearing of the attachments and result in “looseness” in the joint. The maxillary canine teeth are the most frequent sites of oronasal fistula formation and the premolars the least frequent. Lateral Tooth Guidance during Function. A full thickness flap is raised using a periosteal elevator. 3. Start studying Canine Teeth. This problem is often precipitated by persistent deciduous teeth; however, its origin may also be idiopathic. The four types of teeth in small animals are as follows: incisor, canine, premolar, and molar. A dental elevator is subsequently used to further loosen the canine tooth in the horizontal, more apical aspect of the alveolus, finally allowing complete extraction (Figure 30-15). The deciduous canine teeth (Triadan 504, 604, 704 and 804) are vestigial spicule-like structures, 0.5–1.0 cm long, that do not erupt above gum level. On the otherhand, the data with articulating paper were group function type (94%), the canine protected occlusal patterns as 2.5% and the unclassifiable pattern were found to be 3.5%. nasal discharge, food impaction and chronic infection, should be surgically repaired.

In long-term teeth, the order is reversed. Figure 4.24. If single layer repair fails or if the defect is large and of long standing, a double layer technique may be used (Fig. This may result in internal joint derangement and affect condylar and associated meniscus movements. Teeth help a person use their mouth to eat, speak, smile, and give shape to their face. The canine teeth are transition teeth located at the four corners of the mouth. Canine teeth have a wide pulp cavity that in young adult horses may extend to within 5 mm of the occlusal surface; consequently, the reduction (grinding down) of canines in horses (usually for non-scientifically validated reasons) risks causing pulpar exposure. By continuing you agree to the use of cookies. As they spend much of their time in deep water and are not particularly numerous, they are rarely observed. The single layer repair is the surgery of choice. Because of the great length of their unerupted crown (up to 7 cm long), extraction of uninfected canine teeth is difficult and should never be undertaken without good reason.19 Following an appropriate nerve block in the standing sedated horse, extraction is performed by initially removing the vertical aspect of its lateral alveolar wall (Figures 30-13 and 30-14).
