Protraction of Posterior Teeth to Replace Missing Molars - A Case Review

Most frequently lost teeth due to caries or periodontal disease are first and second molars. Missing molars are conventionally restored with bridge or dental implants. However, if second or third molars are sound, missing molars can be replaced by protraction of other molars. A 30-year-old male was referred to consolidate space for implantation on his missing maxillary right first molar, mandibular left first molar and right second molar. However, orthodontic treatment option to protract second and third molars, replacing missing molars was chosen because of the patient’s request to reduce the number of implants. The treatment was achieved after 23 months. Protracting second or third molars could be a viable treatment option for missing molars.
