Manual reduction of articular disc after traumatic extraction of mandibular third molar: a case report.

Camino Junior R, Manzi MR, Carvalho MF, Luz JG, Pimentel AC, Deboni MC - Dental Press J Orthod (2015)

Bottom Line: Disc displacement without reduction with limited opening is an intracapsular biomechanical disorder involving the condyle-disc complex.With the mouth closed, the disc is in an anterior position in relation to the condylar head and does not reduce with mouth opening.By means of reporting this rare case of anterior disc displacement without reduction with limited opening, after traumatic extraction of a mandibular third molar, in which manual reduction of temporomandibular joint articular disc was performed, it was possible to prove that this technique is effective in the prompt restoration of mandibular movements.

ABSTRACT

Introduction: Disc displacement without reduction with limited opening is an intracapsular biomechanical disorder involving the condyle-disc complex. With the mouth closed, the disc is in an anterior position in relation to the condylar head and does not reduce with mouth opening. This disorder is associated with persistent limited mandibular opening.

Case report: The patient presented severe limitation to fully open the mouth, interfering in her ability to eat. Clinical examination also revealed maximum assisted jaw opening (passive stretch) with less than 40 mm of maximum interincisal opening. Magnetic resonance imaging was the method of choice to identify the temporomandibular disorders.

Conclusion: By means of reporting this rare case of anterior disc displacement without reduction with limited opening, after traumatic extraction of a mandibular third molar, in which manual reduction of temporomandibular joint articular disc was performed, it was possible to prove that this technique is effective in the prompt restoration of mandibular movements.

Mentions: A 23-year-old woman was referred to the Oral and Maxillofacial Surgery Service ofAssociação Paulista de Cirurgiões-Dentistas 30 days after accidental extraction of amandibular second molar during extraction of a third molar on the left side. Figures 1 and 2show the panoramic radiographs taken before and after extractions, respectively. Thepatient also reported that the surgeon had considerable difficulty during the surgicalprocedure, which imposed an extensive period of time with the mouth opened. She reportedsevere joint pain on the right side soon after surgery, accompanied by difficulty inmouth opening and a deviation to the opposite side of the extractions.
