Abstract :
Segmental or marginal resection of mandible leads to defects altering the physiological position and movements of mandible. This occurs due to altered muscular action and contracture of scar tissue. Guide flange is a conventional prosthesis that helps to guide the mandible and restores repeated positioning of mandible to improve mastication and to provide support to remaining structures.
Immediate rehabilitation helps in maintaining the balance and counteracts unilateral action of muscles to provide stability. It is difficult to achieve favorable outcome with guide flange alone, if deviation is more and the muscular forces are strong. Adjunctive therapies like physiotherapy, maxillomandibular fixation with elastics, prosthesis anchored to natural teeth or forceful manipulation within physiological limits may be used to correct long standing deviation post surgery. This case report highlights use of (Maxillomandibular Fixation) MMF screws with orthodontic elastics to aid in proper functioning of guide flange prosthesis to
restore masticatory efficiency.
