Intrusion of over-erupted maxillary first molar using a mandibular removable acrylic bite plate

Abstract

Over-eruption of maxillary molar because of loss of the opposing teeth creates occlusal interference and functional disturbances. To provide prosthetic treatment of the missing teeth, these over-erupted teeth need to be intruded, but molar intrusion is difficult in adults. In this report, we present a simplified version of the orthodontic appliances in conjunction with lower removable acrylic bite plate to intrude the over-erupted molars. The method advocated here, uses a removable acrylic plate resulting in a true molar intrusion, thus eliminating an additional surgical step of implant placement. The results showed that the biological responses of the teeth and the surrounding bony structures to the intrusion appeared normal and acceptable.
