: We report a case of cystic lesion in a 23-year-old female, consisting of an oval-shaped lesion adjacent to the temporomandibular joint TMJ . She presented with a Class malocclusion with facial asymmetry and tenderness to palpation on the right TMJ. The patient was treated conservatively with a splint for the TMJ-associated cyst and combined surgical-orthodontic treatment for the facial asymmetry. The post-treatment course was uneventful. The authors recommend a conservative approach as one of the treatment options for TMJ cyst.

This is a case report of a female patient who was 15 years and 2 months old when first examined and who complained about anterior crowding. The patient had angle class III malocclusion accompanied by congenitally missing mandibular central incisors on both sides, telescopic occlusion at the second molars, and proclination of the maxillary incisors. The orthodontic treatment involved edgewise appliances, and a Nance holding arch with extraction of the maxillary first premolars both sides. Treatment involved arranging the lateral incisor as the central incisor, the canine as the lateral incisor, and the first premolar as the canine in the lower dental arch. When aligning the canine as the lateral incisor, it is common to avoid cuspal interference by reforming the cusp of the canine. However, we were eventually able to avoid cuspal interference by performing tooth movement only, and achieved good functioning when guiding the lateral excursive and protrusive mandibular movements without interference.
