RESUMO
Management of patients with congenitally missing mandibular second premolars continues to challenge clinicians to find the best treatment options. The Orthodontist must make the proper decision at the appropriate time regarding management of the edentulous space. If space is left for an eventual prosthetic replacement, the clinician should try to create the exact amount of space required and leave the alveolar ridge in an ideal condition for the future restoration. If the space is to be closed orthodontically, detrimental changes to the occlusion and facial profile must be prevented. Therefore, the correct decision must be made at the appropriate time. This paper presents a case report of a congenitally missing lower left second premolar where molar protraction with orthodontic temporary anchorage device has been done.
