![]() In Type III, buccinator muscle fibers originated from the posterior aspect of the parotid duct and ran posteriorly to the duct.Īs Bradin reported, “for vestibular extensions to be successful, pack should be in position for at least 3 weeks. in the year 2006 on buccinator muscle fibers (based on anterior to exterior position) extending to the terminal portion of parotid duct and finally concluded that muscle fibers extend in three different locations which are as follows: In a anatomical study done by Kang et al. Gingival augmentation would have also been another option for buccinator reposition, as the American Academy of Periodontology recommends that gingival augmentation procedures should be performed to prevent soft-tissue damage in the presence of alveolar bone dehiscence during natural or orthodontic tooth eruption, to halt progressive recession of the gingival margin, to improve plaque control and patient comfort around teeth and implants, and to increase the insufficient dimension of gingiva in conjunction with fixed or removable prosthetic dentistry. Treatment for buccinator reposition is a combination of frenectomy and vestibular extensions. In our reported case, negligible vestibular depth after traumatic extraction along with less attached gingiva on buccal aspect and almost crestal positioning of mucogingival junction precluded proper positioning of the toothbrush. ![]() Ĭan be due to hyperactivity of buccinator (presumably thickening it and putting pressure on the underlying hard tissues). The vestibular depth was almost nonexistent in that area. The origin of the attachment extended to the crest of the alveolar ridge. On closure examination, anatomic reference points and the nature of the attached tissue revealed that it was the buccinator muscle whose attachment was abnormal. On retracting the cheek, a frenum-like band of soft tissue attached at the crest of the edentulous ridge was observed. The height and width of the edentulous ridge were maintained. Tooth no 46 was missing, and the extraction was done because of the decayed teeth. Intraoral examination showed good oral and periodontal hygiene. The patient did not indulge in tobacco or alcohol chewing habit. No medical history and no extraoral abnormalities were detected. On examination, the patient was a well-built, well-nourished, well-oriented, and mentally sound adult. On examination, patient medical history was unremarkable, with no report of incidents of trauma and infections. Intraoral examination and medical history have described a tentative physiological role, suggesting that they act as a dilator of the parotid duct, as the buccinator muscle fibers extend to the terminal portion of the duct. The buccinator usually initiated the sequence followed quickly by the orbicularis oris. The buccinator and orbicularis oris play a major role in beginning the swallow by producing a peristaltic-like wave of contraction, originating in the oral cavity and passing pharyngeally. The superior constrictor muscle, buccinator muscle, and orbicularis oris muscle function as a unit in the acts of swallowing, blowing, sucking, pronouncing vowels, chewing, and coughing. It is usually described as having predominantly horizontal fibers arising from the pterygomandibular raphe and from the alveolar bone of the maxilla and mandible and running anteriorly to interdigitate with the fibers of the orbicularis oris in the corner of the mouth, which composes the mobile and adaptable portion of the cheek. The buccinator muscle may pose problems similar to thick, wide, and crestally attached frenum in the region of molars near its origin over the jaw bones. ![]() For the same reason and also for the purposes of appropriate prosthodontic management, coronally attached muscles may require apical repositioning if not resection. Most textbooks briefly and superficially describe the role of the buccinator as controlling the bolus during mastication, keeping food between tooth surfaces by “compressing the cheeks,” and preventing injury of the buccal mucosa.Ĭohen suggested that the frenum must always be removed when it is so thick and wide that it may interfere with toothbrushing. And finally, insertion of platysma neck muscle among others.īuccinator muscle protects the food from accumulating in the buccal pouches, prevents injury to buccal mucosa by compressing the cheek, and salivary glands produce saliva for softening the food and initial digestion.
